Will 850W be enough even in the future?

post #1 of 38
Thread Starter 
Hello people, i am thinking of selling my GPU and Power supply which are the low points on my pc. I have a 6870 and a 600W Diablotek power supply on an Intel Core i7 2600K. I am looking to add a GTX 580 superclocked and an 850W power supply. I read some places that a 750W power supply can handle the gtx 580 even in sli. Am i going over the edge or should i go for the 850W and just keep it for the future??? biggrin.gif

Depends what kind of rig you want in the future... it's certainly enough for pretty much any single card and sli setup...tri+ sli cf and you might want more.

Depends on the quality of the PSU. 750w should work if you're not into breaking world records and benching or running furmark and prime together. Here is a list of recommended PSU: http://www.overclock.net/t/183810/faq-recommended-power-supplies

This should be in the PSU section.

As far as now 850 is pretty much good for any 2 gpu setup, hard to say if that will be the case in the future though

My XFX Core Edition 850w is running without any problem my 580 SLI so i think if you buy one you will forget of changing your PSU until it dies biggrin.gif

Can a power supply reduce the performance of your graphics card? or can a hard drive reduce in game FPS?
post #8 of 38
I personally wouldn't try to future proof PSUs. Just get the PSU for what you need now.
Currently 850w is good enough for most high end cards in CF and SLI.
650 is good enough for most single GPU systems.

If you can get a good deal on a 750w go with that.
