GTX 680 with 700W OCZ PSU

[twisted_rb]

hi im thinking of upgrading from GTX570 to GTX 680 and i have a 700w OCZ power supply is this a good enough psu? or would i need better?
thanks

The 680 is a poor choice. Get the 670. About the same performance (you won't see a 2-5% difference when you're playing, trust me on that) at a much lower price.

Your PSU might actually be considered overkill in wattage, although I have known some OCZ models to be less reliable than many other brands. It should have enough 12v amperage, but I recommend that you check the 12V amperage to be sure.

Yes....the OCZ 700 is enough

 

[twisted_rb]

ok what is the fps difference between the 670 and 680? and my psu would be ok with both these GPU'S?

 

[hellfire24]

OCZ? what model is it?

The two are almost identical in performance. The 670 uses considerably less power than the 680, but both can work just fine on much lower wattage PSUs than yours assuming that they have the 12v amperage for it. Unless you tell us the 12v amperage that your PSU has, we can't be sure that it is enough,, but I can say that it is almost definitely more than enough. Now, it's reliability is what worries me. Without knowing the model, it is a wild card that I don't trust.

At what resolution? 1080p? The 670 should be able to do that with the texture settings maxed out, although AA and such might be a problem. Make sure that your CPU can handle that much FPS.

i play at 1920x1080 and my cpu is a i5 2500k and i only want to run the game on medium settings not ultra @ 120 fps or even around 100 becuase u can cap the fps in game!

unfortunately your power supply sucks-

grab a 750w and a 670 instead of 680 and faulty psu.670 OC'd beats/matches the performance of a 680/7970.i would suggest this-

note: this power supply has enough power to run 2x 670s in SLi so don't worry about future upgrading.
EDIT: 2500k is a very capable cpu and will not cause any problems.
problem solved

If you want to play on Medium, that's your choice to make, but the 670 can probably do 120 FPS averages even in Ultra, so I don't see the point. Do you have a reason for wanting to play in medium settings?

 

[hellfire24]

psu is one of the most important part,a faulty psu like your can burn your whole rig.

That PSU is a little more expensive than what I'd go for, but XFX is worth that much money. They're just re-branded Seasonic models from what I'm told and that's as good as PSU quality gets as far as I'm aware.

However, if OP has any multi-GPU plans, then I'd recommend AMD Radeon 7900 cards over Nvidia.

@OP
Do you have a preference for Nvidia cards?

 

[twisted_rb]

because on medium i think it looks around the same as ulrta tbh but ofc i will try to run it on high/ultra if i can and also do i definitely need a new psu then?

 

[twisted_rb]

is it certain that my psu is bad because it cost me £80 and its 80 plus certified so i dont see what is wrong

The problem is that OCZ has a lot of unreliable PSUs. They have some pretty good ones, so they're a wild card. I wouldn't go as far as saying that it sucks without knowing the exact model because some OCZ PSUs are actually good, but some are very bad too, so I wouldn't trust it at least until you can give me an exact model number.

PSU quality goes beyond efficiency and wattage. Reliability matters too and some of OCZ's PSUs have some poor quality components that fail too easily and too messily (taking other components with them happens all too often). OCZ doesn't actually make their own PSUs, they simply re-brand PSUs from other companies, so some of them suck and some of them don't suck.

The XFX is great. You can get that.

If you want to stick with your OCZ PSU, then read the reviews that were just posted of it so that you know exactly how to treat it to make it last. If you can't keep with what they recommend, then I recommend replacing it. That OCZ PSU looks like it's a risky PSU to keep to me, but that's my opinion.
