Bronze won't make a difference, depending on the price you could go 600w platinum if you wanted. System Power consumption on the gtx780 is 350-400w, so if you were to OC you would be leaning towards the hotter side of efficiency. I would reccomend a 750w if your planning on a high end gpu and atleast 950w if you plan to sli 2 high end gpus. High end sli will run almost 600w
This was pretty useless, I'm sorry to say. You should have thrown in the el-cheapo power supply, perhaps before putting in two graphics cards, and made a direct comparison. Or even better, you could have gone with a 80plus rated 600W power supply to show how much difference the range of the PS makes. Right now, we have no clue how much of the wattage the sysstem pulls is due to an inefficient range of the power supply.
@declaration963 then why do they make up to 1500w power supplies? ive heard linus say that you dont need anyhtign more than 1250, or are the 1500w for other things?
I'm going to build a computer using: I5 4670K GA-Z87X-D3H 1tb WD hard drive 8GB ram and will be buying a graphics card later if im also intending to OC how much power do you think ill need?
Hey Linus, what PSU do you recommend for my setup? I'm currently looking at a 1200w 80+ Platinum Corsair 1200i Core i7-4930k 4.3 Ghz Corsair H100i CPU Cooler 3x GTX 780 ti (1.1Ghz 3 way sli) 16GB DDR3-1866mhz Ram Asus X79 Deluxe Motherboard
does the PSU get hot at all under stress? I have the same PSU but an i5 2500k @4.7 and a single 560 ti (i know the PSU is overkill, but it was my first build so I was bound to not get it perfect!)... just wondering.
Thanks mate. I bring a smile to my face when people appreciate things. I wanted to do something different. So I went with 2 power supplies. 1 for the hard ware, and the second for Pumps fan controllers, fans leds, cold cathodes. I also wanted my hardware have uninterrupted power seeing that I am running Push-Pull with 35 fans. Couldn't see why not,
Thanks for the video, Linus! I've been wondering for years how much idle power changes with high-end components, but I've never seen anyone review the topic. Its good to finally have an answer.
Hey I don't get this, you have GTX 580 SLI and the power draw is 530w. Does this mean if I have a 550w power supply it would be able to power the two graphics cards?
Superb video about power consumption of a PC. You have cleared all my myths about it. Here at my place there is a lack of continuous power supply and for time being we depend on our inverter-battery set. Your video has given me the freedom of running my PC during that period of time too. Thanks a lot. My rig: processor: intel i5 4670k motherboard: intel 87mc 4th gen ram: hyperx 1333mhz power supply: Cooler master 600W graphics card: nvidia 560gtx (gifted by my friend). :)
i need help im upgrading my graphics card from amd 6670 to a amd 7870 2 GB GDDR5 i have a 850 watt power supply is there enough power for the 7870 or do i need to upgrade
Easily... as long as your PSU is quality and matches the ratings and rail power. Not only is a 850 good enough..... it could probably run two 7870's easily.
i still don't understand with power supply, for example i have 600W, is that mean when i start PC, the power supply take 600W power from the wall? or 600W is the maximum power consumption? Need help, thank you.
Thank you for this video. I have a further question : How many watts do disk drive's typically consume when under load? I need to run at least four drives simultaneously when video editing.
@declaration963 i guess that makes sense, but in general the pwoer consumption wont go up by a whole lot because that just means more heat and more innovation with gpu cooling to counteract that, and the heat produced decreases with smaller architecture, i think its more likely future proof for soemthing like 5-6 way crossfire/SLI
I have a 450w cooler master gx 80 bronze certification and im running a i3-3220 stock ghz (3.3), a asus gtx 650 ti 1 gb oc (normal overclock setting) and i bought a msi z77ag45 gaming motherboard, and i wanted to buy a watercooling kit. Can i ? i have some super talent 8gb ram at 1330ghz
have you had any PSU related problems since then (as it was 8 months ago you said that)? I'm thinking of getting an OCZ 550W 80+ PSU for an FX6100 and 6870 for a friend, and i dont want to have his PC failing a few years down the line.
I had planned for a 520W Seasonic M12II for a build with an 2500k and GTX560ti (well, the Ivy Bridge and Kepler equivalents once they are released), sounds good?
What is the point of having a power supply that can handle/put out 1000+ watts when your wall watts showed in the video final setup that only used 500-600 Watts max?
Just the thing I was looking for, I was really confused about choosing a power supply for when I build a computer soon. Looks like 700W is the way to go indeed. Thanks for the video!
I need some advice. What power supply should i egt with the following config: AMD Phenom II X4 965 BE @ Stock Clock XFX AMD 6870 1GB @ Stock Clock Corsair Vengenace CL9 8GB @ Stock Clock Asus M5A78L-M Motherboard Seagate Barrucuda 1TB Hard Drive 7200RPM Any replies would be greatly appreciated!
can my stock hp bestec 250W (220W max) with 14A on 12v rail handle an upgrade from hd5450 to hd5570 ? if not whats the best i can get ? i am running an athlon 64x2 4600 2.4ghz(89W TDP).
Great explenation Linus, thanks! I'm using an HX1000watt 80+ Gold Modular "Magnetic series". I only got me 1 graphics card. It will do a great job thanks to your explanation of what the components quality mean :)
Thank you. Sure wish we had access to this type of vide when I was studying for my A+ certification back in the early 00s. Now I know why my power bill's so high. LOL! :)
I bought a better graphics card ( EVGA Nvidia 9800 GT). But when i installed it my screen was black and there was no beep. In specs for GPU it says that Minimum System Power Requirement is 400W. My PSU is 230V. Is that the reason that my screen is black ?
i need some help... im going to build a system with: an intel i7 3930k, asus rog rampage IV extreme, sapphire radeon 7970 oc, sound card, 16 gb ram, cooler master haf x corsair h100 and some led strips what power supply should i use ? i might be getting another card and setting up crossfire later. thanks
But the 2 560 ti's still beat a single 680 by a slight advantage, even with the lower vram. The dude in the first comment already had 2 560 ti's, going for a 680 would be a waste of money. He should consider either a 690 or 2 670's, not a single 680 which would give him no advantages except for more expansion room.
What is he using for the basic setup? I'm interested in a low power consumption server with basic CPU. He's using an Intel i3 2100(T?) CPU and H67 motherboard? But what exact setup? There are alot of motherboards with an H67 chip..
Hey guys..i have a doubt here.Atm i have a thermaltake tr2 rx 750w powering an hd 5850 and a AMD phenom ii x6 1055t. But i want to upgrade my psu to a newer one.Like 850w or 1000w.I have a budget of 300bucks..what do u reccommend me?(of course i will upgrade my VGA AND CPU in order to match the psu)
Thanks for the reply! I overclocked my i5 3570k @4.1Ghz, and im also planning to OC my 2 680 lightnings to 1.212v. Still ok? I just want to make sure. Cheers!
Is going from a 600W random PSU to a 1250W 80+ Gold a logic upgrade ? 3570K GTX 650 Ti Corsair CX430 - at max load on GPU and CPU 191 Watts from the wall ???
this video helped me A LOT, thanks for the info linus.. right now i'm running AMD FX4100 @3.6ghz 8Gb of ram @1600mhz XFX 9500GT @ 512mb gigabyte 970a-ud3 1 HDD of 750gb caviar green i'm running this rig on a LNZ650kr (it came with my sentey bx 4246) i'm going to upgrade my graphics card.. and i have a doubt... is this PSU going to support a GTx460? answer me please XD because i'm between that one or the GTS 450..(without changing my PSU of course)
Whats the best power supply i can buy for my specs? - Intel Quad Core Q9400 @ 2.66GHz - ATI Radeon HD 4600 - Asus P5Q SE2 - 4GB Ram DDR3 At the moment im running on a 500w but i think its too low and maybe i should get a 1000w?
I have a 500w psu with a foxconn 945 7mc mobo with E6300 stock with stock cooler and 2gb corsair ram and a galaxy GTX275 with windows 7 with a 160gb hd+120hd+80gb hard drives and two disk drives with two 120mm fans should i get a bigger psu?
@declaration963 wow, i guess ive alwasy severely underestimated what power supplies are capable of, makes me think that all those 1500w ones are pointless
So the wall supplys your pc with AC power and the PSU converts that into DC power. If my system draws 700w DC power it will only draw (estimate) 400w AC power. What I am asking is when your computer is converting power to DC do watts increase from what is being take from wall?
I've been using a Thermaltake TR2 RX 750 watt PSU for over 2 years. I didn't know about its problems once it gets past 650 watts, but I've never encountered a problem with it. I had a XFX 750i motherboard with a Q9650 and 2 Palit Sonic Edition GTX 460s (1024 MB) in sli back in 2010 and recently upgraded my motherboard to a ASUS P8Z68 V with an i5-2500k. I've OC the CPU to 4.6 Ghz and the video cards to 800 Mhz, with 8 gigs of 1600 Mhz DDR3. Runs like a champ.
One year ago, I bought an Asus desktop PC. It has an Intel i5-2320, 6Gb ram, an HDD and a not so good Asus mATX motherboard. The GPU on this is only a Gt 620, so I have decided to upgrade to a GTX 650 Ti. Will this run okay on my stock 350W PSU, or should I upgrade it? Preferably, I'm going to be lazy and keep the 350W, but could this lazyness be fatal?
@Thecashflowman should be fine for normal usage. You basically got 1 extra 6970 and 300W more capacity. The 6970 will never use more than 250W (typically around 190W under load) so you should be good to go.
im a noob at gaming/building pc's... My amd radeon7750 1gb card needs at least 450watts. (other specs:AMD Processor - AMD FX-4100 3.6GHz (Quad Core), 8gb ram, 1tb HDD) Do I need to buy a greater psu?
I have a FSP Everest 800W PSU Rest of the system: - Intel Core i7 2600k @ 4,6Ghz, with Corsair H50 - Corsair Vengeance 8gb 1800Mhz RAM - ASUS Sabertooth P67 - ATI Radeon HD 5970 - OCZ Vertex 2 60GB, WD Caviar Black 2TB Do you think my PSU is enough? Thanks!
i have a corsair 80+ 650 watt PSU; my GPU is an amd radeon 6870 and my CPU is an amd phenom ii x6 1100t. i was thinking of overclocking my CPU to something like 3.9 or 4 GHz so i could get more performance, but i don't know how much more wattage this would cause my CPU to draw. is my 650 enough? or maybe i'm better off only bumping it to 3.6 or 3.7 ghz?
i have intel core i3 2100, 2x4gb ram 1333, gtx 670, 2x500gb caviar blue, and an asus p8h61-m le I have a cooler master 550watt power plus, would that PSU be enough? i am not overclocking anything
Very nice video! I put in a Cosair PSU that is somewhat over powered, as they don't start their fan before they reach 40% load. That means that I have a "fan-less" PSU 99% of the time and since I am only a casual gamer this is perfect for me. A true 650W fan-less PSU is way more expensive than my 850W Cosair.
So will my cooler master silent pro 1000 watt be able to power and dual sli setup besides two 590s. I have an i7 930 oc'ed to 3.8ghz on my msi big bang xpower and one hard drive
NVIDIA recommends 720+ watts, but you will probably get away with a high quality 650 watt. I am using 2 760s and I've got a 750 watt Rosewill Hive PSU.
650 watts will be MORE then enough. you should not look at the tdp to calculate the system power usage. use a power calculator website and you will be surprised.
I have geostar 680w mid case with fan 1x120mm fan 4x80mm fans I am experiencing over heat my thermal paste dryed to CPU do I need new paste and what is good cooling fan for x4 CPU.?
I7 3770 (non-k I got it for $125). XFX AMD Radeon HD 7850 2gb, 8gb of Viper 3 Series 1600mhz ram (2x4), ThermalTake Smart Series SP-750M PSU and a Z77-G45 motherboard. What would you rate this system?
I have a 550 watt power supply and I'm building a PC with a gtx 680 and a 3770k. IS this enough?(8gb ram, 1 hdd, 1 ssd, asus sabertooth, disk drive, haf x case)
Oh, i see. So, if you're not doing any overclock, just the default configuration, 600w is ok. The part of "try 650 or 700" was just my personal opinion. I like to have clearance in power output, just to have sure. PLUS, if i want to upgrade your PC, you don't need to upgrade the power supply because you already have a good and powerful one. In my case, i use AX850 and already upgraded my intire build 2 times.
I haven't bought the psu (450watt), but the guy at bestbuy said that 450watts will run fine... What im confused about is if the psu only powers the gpu or also all the other parts of the pc.
You will never need more than a 600w bronze for any single GPU system, even when overclocked.
Bronze won't make a difference, depending on the price you could go 600w platinum if you wanted. System Power consumption on the gtx780 is 350-400w, so if you were to OC you would be leaning towards the hotter side of efficiency. I would reccomend a 750w if your planning on a high end gpu and atleast 950w if you plan to sli 2 high end gpus. High end sli will run almost 600w
***** Agreed. There's OEM microtowers running an i7 and a Titan off a 330w external power brick.
6 years later, rtx 3090 lists 750w as a recommended requirement
@@alexwhite1624 lol was about to make a joke about this
do you have 2 560 ti's and one 680 to prove me wrong? because all the other benchmarks point to that result.
This was pretty useless, I'm sorry to say. You should have thrown in the el-cheapo power supply, perhaps before putting in two graphics cards, and made a direct comparison. Or even better, you could have gone with a 80plus rated 600W power supply to show how much difference the range of the PS makes. Right now, we have no clue how much of the wattage the sysstem pulls is due to an inefficient range of the power supply.
@declaration963 then why do they make up to 1500w power supplies? ive heard linus say that you dont need anyhtign more than 1250, or are the 1500w for other things?
that rabbit video its creepy
Would a 750w psu be enough for a 4.2ghz 2500K 16gm of ram at 1600mhz and a 7970?, it is a good quality 80+ gold psu but im not sure
You should redo this video and use all sorts of machines ranging from your Scrap Yard Wars pcs to your gaming pc/ servers.
I'm going to build a computer using:
I5 4670K
GA-Z87X-D3H
1tb WD hard drive
8GB ram
and will be buying a graphics card later if im also intending to OC how much power do you think ill need?
great videos as always dude... love your comments and the way you think about computer hardware specs, thanks keep posting and ill keep watching
2021 update!
Hey Linus, what PSU do you recommend for my setup? I'm currently looking at a 1200w 80+ Platinum Corsair 1200i
Core i7-4930k 4.3 Ghz
Corsair H100i CPU Cooler
3x GTX 780 ti (1.1Ghz 3 way sli)
16GB DDR3-1866mhz Ram
Asus X79 Deluxe Motherboard
Ask the forums on linus tech ,you'll get your answer within a day.
You should be fine with that config. You can use pc part picker to guestimate your power needs.
JacobStar91041 3way sli, 4930K and asking what PSU you may need. You clearly do not know what you're doing, do you?
Sorry if this has been asked in any of your video's but where did you get your test bench and what brand is it?
I LOVE the volume in this video.not low but near loud and clear.
Best and most informative episode about COmputers I have ever seen on TH-cam!!! Nice 1
does the PSU get hot at all under stress? I have the same PSU but an i5 2500k @4.7 and a single 560 ti (i know the PSU is overkill, but it was my first build so I was bound to not get it perfect!)... just wondering.

@jamesl1324 That's no where near "blowing up" do you have a dedicated graphics card in the computer?
That made things a lot easier to understand, and I have an understanding what I can put in my computer now.

Yes, no question.
Thank you for this video.
I have a further question : How many watts do disk drive's typically consume when under load? I need to run at least four drives simultaneously when video editing.
What is that tray you put the motherboard, powersupply, etc on? Thanks for respone
very cool video!!!! I had a lot of questions about power consumption but after seeing this they are all cleared out! Great job Linus!
@declaration963 i guess that makes sense, but in general the pwoer consumption wont go up by a whole lot because that just means more heat and more innovation with gpu cooling to counteract that, and the heat produced decreases with smaller architecture, i think its more likely future proof for soemthing like 5-6 way crossfire/SLI

Great video, I dig this link out every time I see people saying that they "need" a 1000W+ PSU :)
can my stock hp bestec 250W (220W max) with 14A on 12v rail handle an upgrade from hd5450 to hd5570 ? if not whats the best i can get ? i am running an athlon 64x2 4600 2.4ghz(89W TDP).
so would it be a bad idea for me to run two 7850's off of a 600w psu? Ive also got a fx 6300 at 3.5 ghz (stock)

Awesome video mate, it's great to still continue to learn more and more about computers even though I'd consider myself a pretty hardcore user.
Whats that called that all the components are installed in? Like instead of a case...

what power supply should i use ? i might be getting another card and setting up crossfire later. thanks
Thank you for this awesome video. It did help me understand more about power consumption. I use the OCZ ModXstream Pro 700 watts.
I am using a Silver Power 750W Modular. With only a 550ti.
This video made me understand how little power my PC actually would demand
Thanks Linus. A very helpful vid. Interesting seeing how inefficient a PSU is if you are not running it with the better components.

Hey Linus, could you please redo this test with parts of 2018? It is really interesting to see what your PC does to your electricity bill.
Chat on the LTT chanel i think this channel is inactive
ok,please tell me if your system draws 150w why do you need 1200w power suply wouldnt a 200w psu be good ?
sory for my bad english
So if the meter shows that my computer is at 489 watt full load will it be safe to use a high quality 500W power supply?
Thanks for the reply! I overclocked my i5 3570k @4.1Ghz, and im also planning to OC my 2 680 lightnings to 1.212v. Still ok? I just want to make sure. Cheers!
how much watt would a regular HD5770 with an Athlon II X4 640 quad core, 8gb kingston value ram consume?
Is going from a 600W random PSU to a 1250W 80+ Gold a logic upgrade ?
3570K
GTX 650 Ti
Corsair CX430 - at max load on GPU and CPU 191 Watts from the wall ???
If i'm going gtx 680 sli,,is 750watts PSU enough? talking about the corsair 750zt modular PSU.
is the thermaltake toughpower 650w enough for gtx 660 ti amd fx 8120 and 8 gb corsair vengeance?
i already have the i3, so what video card would be good for my processor?
What would be a good wattage and brand psu for the rig I want to build?
amd fx 6100 six core processor
8gb ram (possibly 12 or 16)
geforce gtx 550ti
this video helped me A LOT, thanks for the info linus..
right now i'm running

i'm running this rig on a LNZ650kr (it came with my sentey bx 4246)
i'm going to upgrade my graphics card.. and i have a doubt...
is this PSU going to support a GTx460? answer me please XD because i'm between that one or the GTS 450..(without changing my PSU of course)
This was an incredibly informative video! Thank you.
I'm using a 750w Zephyr PSU, powering 2x 9800GTX+ GPUs and a AMD 965BE CPU.
Whats the best power supply i can buy for my specs?
- Intel Quad Core Q9400 @ 2.66GHz
- ATI Radeon HD 4600
- Asus P5Q SE2
- 4GB Ram DDR3
At the moment im running on a 500w but i think its too low and maybe i should get a 1000w?
I have a 500w psu with a foxconn 945 7mc mobo with E6300 stock with stock cooler and 2gb corsair ram and a galaxy GTX275 with windows 7 with a 160gb hd+120hd+80gb hard drives and two disk drives with two 120mm fans should i get a bigger psu?
SO I would be correct that running a 2500k overclocked and 2 6950s in Xfire with an 850W Antec True Power Quattro would be fine?
@declaration963 wow, i guess ive alwasy severely underestimated what power supplies are capable of, makes me think that all those 1500w ones are pointless
So the wall supplys your pc with AC power and the PSU converts that into DC power. If my system draws 700w DC power it will only draw (estimate) 400w AC power. What I am asking is when your computer is converting power to DC do watts increase from what is being take from wall?
I've been using a Thermaltake TR2 RX 750 watt PSU for over 2 years. I didn't know about its problems once it gets past 650 watts, but I've never encountered a problem with it. I had a XFX 750i motherboard with a Q9650 and 2 Palit Sonic Edition GTX 460s (1024 MB) in sli back in 2010 and recently upgraded my motherboard to a ASUS P8Z68 V with an i5-2500k. I've OC the CPU to 4.6 Ghz and the video cards to 800 Mhz, with 8 gigs of 1600 Mhz DDR3. Runs like a champ.
AMD 8350 and GTX660..what psu do I need? pls answer!
a 450w would be plenty for that.
Tunknatar thanks!
@hecjr82
2 quad core cpus? You are pushing it on that setup, because a 560ti requires a minimum of 500w
One year ago, I bought an Asus desktop PC. It has an Intel i5-2320, 6Gb ram, an HDD and a not so good Asus mATX motherboard. The GPU on this is only a Gt 620, so I have decided to upgrade to a GTX 650 Ti. Will this run okay on my stock 350W PSU, or should I upgrade it? Preferably, I'm going to be lazy and keep the 350W, but could this lazyness be fatal?
Hey guys, what psu would you suggest for a system with a FX8120 and crossfire 6850s?
@Thecashflowman should be fine for normal usage. You basically got 1 extra 6970 and 300W more capacity. The 6970 will never use more than 250W (typically around 190W under load) so you should be good to go.
can i sli 560 ti 2 gbs with a XFX pro 750 watt psu? i'm running a single 560 atm but i'm thinking of geting a second if my psu can handle it
Might be a bit on the limit there, but if you don't mind that fan spinning to full RPM and the noise it will make, I think it should work just fine.
Very informative. I would like to see more videos like this one
I'm wondering, is 750w enough for R9 280X 2-way crossfire, with a quad core i5 4670K?
im a noob at gaming/building pc's... My amd radeon7750 1gb card needs at least 450watts. (other specs:AMD Processor - AMD FX-4100 3.6GHz (Quad Core), 8gb ram, 1tb HDD) Do I need to buy a greater psu?
I have a FSP Everest 800W PSU
Rest of the system:
- Intel Core i7 2600k @ 4,6Ghz, with Corsair H50
- Corsair Vengeance 8gb 1800Mhz RAM
- ASUS Sabertooth P67
- ATI Radeon HD 5970
- OCZ Vertex 2 60GB, WD Caviar Black 2TB
Do you think my PSU is enough? Thanks!
what's the thing plugged into the surge protector?
i have a corsair 80+ 650 watt PSU; my GPU is an amd radeon 6870 and my CPU is an amd phenom ii x6 1100t. i was thinking of overclocking my CPU to something like 3.9 or 4 GHz so i could get more performance, but i don't know how much more wattage this would cause my CPU to draw. is my 650 enough? or maybe i'm better off only bumping it to 3.6 or 3.7 ghz?
i have intel core i3 2100, 2x4gb ram 1333, gtx 670, 2x500gb caviar blue, and an asus p8h61-m le
I have a cooler master 550watt power plus, would that PSU be enough? i am not overclocking anything
I have a GTX670, A10 5800k, 8gb of 1300mhz vengeance RAM, With a Corsair 650W PSU all ordered for chirtmas time.
Will this be enough to run?
Very nice video!
I put in a Cosair PSU that is somewhat over powered, as they don't start their fan before they reach 40% load. That means that I have a "fan-less" PSU 99% of the time and since I am only a casual gamer this is perfect for me.
A true 650W fan-less PSU is way more expensive than my 850W Cosair.
So will my cooler master silent pro 1000 watt be able to power and dual sli setup besides two 590s. I have an i7 930 oc'ed to 3.8ghz on my msi big bang xpower and one hard drive
Would a 650w psu be enough for an AMD fx 6300 and SLI gtx 760s?
Thats cutting it very close. What power supply do you have?
I'm still researching for my first build, so I don't have one yet.
2DoubleLightsabers A 650w PSU should be able to run that; make sure you get a really good PSU though.
NVIDIA recommends 720+ watts, but you will probably get away with a high quality 650 watt. I am using 2 760s and I've got a 750 watt Rosewill Hive PSU.
650 watts will be MORE then enough. you should not look at the tdp to calculate the system power usage. use a power calculator website and you will be surprised.
Im planning to SLI my MSI Gtx680 Lightning. Will my silverstone 750w 80+Gold do the job?
I have geostar 680w mid case with fan 1x120mm fan 4x80mm fans I am experiencing over heat my thermal paste dryed to CPU do I need new paste and what is good cooling fan for x4 CPU.?
Cool vid... I always wonder how much my system is drawing... How much for one of those meters?
Is it safe to use a power strip for a PC?
i use a 430w psu with a radeon hd 7850 and amd x3 450 3 core processor 4gb ram should i use a more powerful psu ?
I7 3770 (non-k I got it for $125). XFX AMD Radeon HD 7850 2gb, 8gb of Viper 3 Series 1600mhz ram (2x4), ThermalTake Smart Series SP-750M PSU and a Z77-G45 motherboard. What would you rate this system?
I have a 550 watt power supply and I'm building a PC with a gtx 680 and a 3770k. IS this enough?(8gb ram, 1 hdd, 1 ssd, asus sabertooth, disk drive, haf x case)
This video was great!!! I'm just getting into building a PC and this helped a lot
Oh, i see. So, if you're not doing any overclock, just the default configuration, 600w is ok.
The part of "try 650 or 700" was just my personal opinion. I like to have clearance in power output, just to have sure. PLUS, if i want to upgrade your PC, you don't need to upgrade the power supply because you already have a good and powerful one.
In my case, i use AX850 and already upgraded my intire build 2 times.
I haven't bought the psu (450watt), but the guy at bestbuy said that 450watts will run fine... What im confused about is if the psu only powers the gpu or also all the other parts of the pc.
