Pretty much, the old CX400 is great too.
Not saying the others are bad, just that there are much better options for the same price.

As said, get a cheap but reliable PSU and check if you can OC more. worst case scenario: you'll have a better PSU.
Have a look at the CX, TX or GS series from corsair smile.gif
doh.gif The CX, TX and GS series are the worst quality PSUs that Corsair sell.
I know, but they're decent for the price.
I agree on the seasonic PSUs though, they're epic.
If you have the cash, you might as well check out the Corsair HX or AX series. Silverstone striders are also viable and not too expensive considering how well they perform.

Are the guys recommending a new PSU even reading the topic?
Another PSU will not suddenly make the power usage of the videocard go up.
It just depends on the type of games you play.

A quality PSU is always good to have, but it will not solve OP's "problem". (which is not really a problem)

It's so easy to get carried away talking about PSUs though! biggrin.gif
Even if the PSU isn't the culprit (probably isn't), it's still a good idea to get rid of that generic 450W.

OP: bottom line you need a 550W PSU to run with some head room for OC.. 650 to Run with PLENTY of headroom

1- Calculate your power with This Calculator
2- Choose the cheapest or the one that suits your budget from This List

Problem solved.

have fun biggrin.gif

AX > HX > TX > GS > CX > VS

VS is like absolute cheapest that's not dangerous. CX is decent on a tight budget. New GS is pretty good these days. TX is good, HX is mostly beefed-up version of GS with better parts. New AX are among the best out there.

TX / GS / CX as suggested would definitely be upgrades over what the OP's currently running, but that doesn't necessarily mean that any of these are at good prices and should be bought. Sometimes they are, especially CX.
post #18 of 32
Thread Starter 
I have an SG06, which means it only fits SFX PSUs... Your Corsair suggestions are nice, but they won't fit, or else I would have already upgraded. tongue.gif

Thinking about upgrading to an SG08, which would come with a suitable PSU for the price, but I'd want to swap it out for an SFX because of a case mod I'm working on with Dwood.

The 670 FTW recommends a minimum of 30A. If 30A is 100%, then 36A would be 120%, right? So wouldn't that mean that my theoretical power target would be 120%? But that's 432W (36A*12V), out of a total of 450W for the PSU. Meaning that at least some of that power has to be reserved for my CPU, mobo, and other components. This would leave less power for my GPU. That logic is what makes me believe that my PSU really is the limiting factor here.

What do you guys think?

Edit: Oh, and my friend and I are running identical cards on the same bench, Valley. I know there is a difference between each card, but this difference is quite vast. If I do end up getting the SG08 I guess I'll find out...

Ask him if you can test your card in his rig biggrin.gif

Im not sure what your system rig is, but im currently using the 450 watt psu with my GTX 670 SC (4gb) and SG05, according to my meter im only pulling 300 watts on load (from the wall). tongue.gif So i would say from what i can tell it shouldnt be the PSU
