670 and PSU question

[joe pineapples]

Hello

Was thinking about selling my 670 to someone, but his PSU is only rated 28A on the 12v rail (Corsair builder series 500W), and I see the 670 needs 30A minmium. Just wondering if he might get away with it, or if anyone has had experience of running one with that PSU.

thanks
joe

Depending on the rest of the system it's likely to be fine.

What are the specs of the PC?

AMD Phenom II 955 Black Edition Quad Core
4gb DDR3
1TB HDD (plus maybe 1x 500gb)
DVD Writer

:/ AMD room heater, they would put it right on the PSUs maximum load, if you managed to load the CPU and GPU to 100%.

It would probably run, but I personally wouldn't, particularly as it's a budget PSU running close to it's maximum output.

What GPU is he running now?

I think its something like a GT440.

100 W+ jump from what he could be using.

Investing in a Power meter might help test it out. (Remember to factor in efficiency, take 10% off the reading. (It's probably 20%, but better safe than sorry)

It's certainly on the limit if you manage to get the CPU & GPU at 100% load at the same time, this would be quite hard, but it is possible.

Unfortunalty I can't recommend this, even though it may be fine there is some risk. I tend to stick with the 80% rule, spec within 80% of the maximim output. Maybe up to 90% with a High end premium PSU.

This looks to be in the 90-100% range.

Thanks Sasahara. From what you've said, and my own initial thoughts, I might see if I can get a buyer for his PSU, then get something better for him + my gfx card.
