A friend made a really neat twin PSU PC a few years ago. As he wasn't running any optical drives he removed the 5.25" cage and mounted the second PSU up there at the front. He hard wired a spur from the original PSU's power socket into the second power supply, and somehow triggered the second one to wake up using a MOSFET. He also replaced the 5.25" bay covers with a perforated alloy plate so the extra psu had somewhere to blow air out of. It all looked very tidy when he finished. The reason for doing all this was because he had a couple of overclocked GTX 980 ti graphics cards SLIed in there, and during heavy gaming that pair would suck up over 500w all by themselves !!! He already had a really good 600w PSU in there, but found the system was getting unstable at the limit, so as he had a spare 450w unit sitting about doing nothing, he decided to just add that. The new PSU ran one 980 and all his RGB, while the original ran the second 980 and everything else. He ran it like that for a couple of years before the lure of newer gaming hardware became too strong. Apparently the only issue he ever had with this setup was the ridicules amount of heat it produced. In summer, after a few hours of gaming, he'd have to open his game room window to let the temperature drop to a barrable level, and in winter he could near as damn it turn the houses heating off. :D
Adapters can get very easy and cheap. If in your area not available, you can make one very easy yourself. Swapped cases and PSU's with these HP motherboard quite few times and it works perfectly. Actually got one of those adapters spare right now, as they are cheap, got one just in case will get another PC swap of this type. :) Also making it work with no error messages or needing to press F1 on startup. Everything is doable.
@@AxeFxMikenot sure on this one. I can see that this board have 24pin connector. Never done one of these before. If original power supply uses 24 pin, then obviously you will be fine with standard PS, if it uses 6pin, then I guess one way to find out is to try using 24pin connection and see if it works.
Still confused what makes a custom build z440 is a prebuild system ?? ( I mean before you upgraded it) Also with the video why not buy a bigger case to house the psu motherboard and gpu etc
I've been doing that stupid thing for a year now as main computer (i.e. 2 power supplies) So, now, to turn it on: dedicated video card PSU as #1, then turn on the computer. Reverse order to shut it off. Burns more electricity though - 2 psu's No extra relays needed. MY PSU has a switch on it and and plug on 24 connector to turn it on automatically. Another stupid thing is cutting close cover open so that larger video card can fit into that small factor SSF with a grinder :) I think it looks nice now.
LOL Mate, don't feel alone at all, A month ago I was thinking "Oh yeah, I'll flex on my buddy with a dual socket Windows xp era build, heck yeah, here's a xw-6200 board for like 20$" Little did i know there's the proprietary heatsinks and power supply, and I've now got another lovely money hole ! :D
@@Robonza Hey ¡Glad to know! I just want to thank you a lot because i've learned something new, and also very useful.

@@Apologized9 can you give us an update. What product did you buy exactly. This is a useful post but a lot of knowledge hiding on vital info is being used by people that claim to have a solution
I'm having the same problem and I was thinking the exact same thing to hook a 12 volt relay to one of the 12 volt Hearts coming off that thing and now that I ain't seen your video and know that it works I'm a goddamn genius
Wouldn’t doing this damage something or short circuit since I have the same issue because I bought a power supply for an rx6600 but the ps won’t work with the motherboard
Sometimes you need to change the P2 6 pin connector cable position on the adapter for it to work, can't remember exactly which one, but sometimes they put one cable on the wrong position on P2 6 pin connector and it is what makes it faulty. You can find the correct configuration, and switch the little 6 pin (1 cable) to the right configuration(cables position, which should be just a single cable that you need to reposition) and it should work right away.
@@Robonzaplease help I turned off my PC but the other PSU was connected directly to GPU and it was on for long time, now my GPU won't turn on please tell me what happened, it's can be fixing?
Genius! -Thank you for sharing. I would like to apply your solution to power a high wattage external GPU connected to an HP Pro 6300 SFF. Do you mind providing some close-ups or explanations of the red & black wire splices, and a part number of the relay you used. Much obliged!
Any old 5v or 12v relay will work. You simply connect it to the 12v or 5v hard drive power depending if you choose a 5v or 12 relay. The relay normally open contacts start the 2nd power supply, just google "atx power supply turn on without motherboard"
@@Robonza Thank you for your response, Sir! Since then, I found out that your Power idea/solution/concept is not only genius, it is also commercialized as this product: "ATX 24Pin to SATA Dual PSU Power Supply Sync Starter Extender Cable Card". When you Google it, the Amazon purchasing option is one of the first to show up, but other companies such as eBay and AliExpress sell these adapters too. The ATX adapter kind with a SATA connection to your PC is the easiest connection, in my opinion.

Funny thing is I have a hp with a 190 watt psu. Well this is what I did the cpu used 65 watts of power I got a evga gforce gtx 750 ti ftw 2gb card that used 65 watts got a sata power adapter to 4 pin molex to power the card. It runs fine. Lol I play yakuza like a dragon at 30 fps 1080p med settings it's not too bad. Really did not need to do it because I have a ps5 and series x. I did it because it mad me mad.
Am I getting this rite your system used a total of 130watts which is still under 190watt power supply? Does the psu wattage plus and the gpu wattage have to be summed up to know how much wattage on a power supply is required
@trulgn yes, most of the rest is board power, and it was 50 watts it works fine to this day. The 750 ti doesn't take 65 w more like 45w most of the time gpus take less than what it says. I build a pc later so I was mostly wondering if I could get the 750 ti to work.
Ok here I am again. I did the same thing, however it should be noted that a diode should be placed in reverse bias across the coil terminals of the relay.
@trulgn if you don't have any knowledge of electronic circuits, I wouldn't recommend doing any of this. I ended up using the card in a different computer with the same issue and I didn't need a relay I actually just used a npn transistor and a 10K resistor. This is basic electronics and if you don't have knowledge then I'm not going to recommend anything. I'm not going to be responsible for you frying your machine
