GTX480 SLI on 750 w PSU ?

post #1 of 38
Thread Starter 
Hey guys !!

I need some opinions on the subject because i have a good deal on
Inno3D GTX480 but if i buy it i wont be able to afford a new PSU for a while.
So im thinking if there's any way to make this work with my current PSU .
Now i know i should have at least 850W PSU but maybe there is some way to make it work with the on i have now at least for the moment.
Naturally i would get rid of dedi PhysX 275 maybe take off the OC what do you guys think any ideas ?
And what are my risks with doing such thing i don't want to compromise my other components.

I usually recommend an 850W.

People have told me they've had GTX 480's in SLI on a 750w PSU and have had no problems, whatsoever.

I'd like to know the general consensus on this as well, seeing as how I have me a GTX 480 and would certainly consider another one in SLI later on down the road.

480 SLI @ stock can work on a good 750W. Never overclock or run Furmark on it though. I repeat...never run Furmark if you do.

850W would really be better though.

OK sounds good.
Will taking off OC on the CPU help ?
Im going to get a new PSU anyway but i'd like to use those babies in SLI in the meantime.

I agree. Just make sure the PSU is from a reputable company (Corsair, Antec, Seasonic, etc.).

My rig will pull a little over 850W peak. I've seen it in the 880s. I have several drives and 9 case fans though too
