Power Supplies for Cards

post #1 of 12
Thread Starter 
In theory.. if I wanted to, could I get another power supply and have it dedicated to my video cards? In this case potentially 8800gts' in SLI?

I cant see why not. you would prolly have to mod ur case to fit the extra PSU though. I have had another PSU running just my card, just to see if there was any kind of performance increases (there wasnt) but if you are worried about power, then I cant see why not.

You'd also have to find a way to turn the PSU on when you turn on your first PSU. That's the toughest part, the PWR_ON leads need to be connected between the PSU's.

Does it really need to be a specially designed one though? surly he can just use a seperate PSU. each connection only uses 12Volts, regardless if its pluged into a MOBO. and like i said, I have done this, and it caused no problems whatsoever.

lol, i cant be bothered explaining, but here's a guide:

basically, the green wire is the PSU_ON wire. link those, and the ground wire, and they should both fire up.

you might want to see about getting a dedicated ps just for you video cards depending on how much your ps currently can handle because the 8800gts in sli will run with a decent 600 watt ps....... so my best suggestion for you would be that would be that you first find out howmuch power you are pulling at this site
http://www.extreme.outervision.com/p...ulatorlite.jsp

i recommend it if you want to find out where your pc stands at how much watts it uses.
