WHich power supply?

post #1 of 29
Thread Starter 
I am upgrading my system power supply and I cannot decide between these units. I want to upgrade my video card to either a gtx 580 or 6970 and I would like some room to grow. I may eventually replace mobo and go bulldozer....

Kingwin Lazer gold 850w
Silverstone Strider Plus 850w
XFX black edition 850w

any input would be supremely appreciated!

Thanks

There is nothing wrong with your current power supply for your rig. You will use 350w in heavy games. I would downgrade and save money. But if you must...get the XFX. It's made by seagate i believe.

He's right. You'll never go over 400W. Absolutely pointless to get an 850W. And your PSU is very good already.

Your EA650 is fine for a single 6970 or GTX 580.

I believe you mean seasonic... I have heard rumors of some squealing noise and it is ugly as sin...

Seems like all manufacturers have been having problems with squealing/coil whine lately anyway...

Yeah, this.

Edit: PSU calculators are grossly inaccurate, ignore them. I ran my i7 and 5970 on a HX650 and still had loads of headroom.

ok so I may not need the new psu, however if I were to upgrade would I be better off with the Kingwin or the Silverstone?
