How to use 2 PSUs in one system.

post #1 of 8
Thread Starter 
I have 2 PSUs, and rigging everything up once a month for BGBs each month is a hassle. Is there an easier way than connecting the additional video cards to the PSU and jump starting it? (lol at jump start) If there is an easier way, please let me know!

Its the green wire that registers a signal from the system that the power button has been activated. There is probably a guide to doing this yourself, but the adapter is so much easier. Just follow the advise the above members posted.

here is an OCN thread with a tutorial if you want to try it yourself:

HardOCP did a pretty good overview/review of retail solutions out there if you don't wanna do it yourself.

Just be aware of crossloading and ensure there is some load on the +5/+3.3v rails on older units.

I did this with 2X 750W PSU's before buying my big one.

If you don't want to buy the connector, simply run 2 wires, one from the green and one from an adjacent black wire at the motherboard, to the matching green and black wires on the second PSU, and the 2nd PSU will then power on/off with the first.
