2 Power Supplies

post #1 of 22
Thread Starter 
Is it possible to split two PSUs to one system? Or would that be a hazard? I haven't had the guts to test it...

No, it's not possible.

How you're going to split two PSU into 1? BTW, here's the meaning of split: http://dictionary.cambridge.org/defi...6704&dict=CALD

Now, yes, you can combine two PSUs into 1 but there's some sort of cable that would allow the PSUs to turn on at the same time when both hooked to a motherboard. Where can that cable be bought? Not sure but there's gotta be a place, google it!

You cant split the power but you can dedicate, so one for the mobo and hdd's and the second for fans lights and pumps

I also have a problem. I bought a newer PSU for an old rig and I hooked it up right and it turns on but the monitor doesn't work!!! The GPU is running because I can feel the fan! What is WRONG?!?!?

Sounds like you missed the 12v. Double check connections.
