I'm wondering what sort of wattage people may think I should grab for a new PSU. I am trying to overclock my GPU to it's max, and plan on overclocking a 4670 in the future.

I want a new PSU because at the voltages I'm throwing at my 7950 (1.17v) my PSU is making weird noises and I get bad instability in games, even though I pass benchmarks after a good long run.

My current PSU is an 850W Orion cheaper, and i really don't want to fry any components so I want something different. I plan on OC'ing my CPU and GPU more.

My setup is as follows:

M4A78-E Asus MoBo
Phenom 965BE
Sapphire 7950 (1100/1500 @ 1.15-1.17v)
3 HDD Sata Storage
1 SSD
3 120mm LED fans
1 200mm LED fan
Front Panel Fan Controller.

I realize I can plug these numbers into a calculator and get a rough estimate, I jsut don't know how much more juice is wanted from a PSU once you start overclocking/overvolting...

Edit: Also, my price range is 75 - $99, willing to budge a bit.

Any help/recommendations is appreciated!

well... the gpu is a 250W gpu at the MOST... and the cpu might draw 180W from the wall at the highest overclock you can stick on it... that means your cheappie psu is real junk if it's struggling with what is effectively a 450W build. Grab yourself a 600W psu from corsair, antec, seasonic or xfx make sure it's a bronze certified or better, to give yourself some wiggle room and call it a day. that should handle your future i5 as well.

Really? I had no idea it was that low. And yes, this PSU is garbage. It was cheap at the time and, well, been stuck with it. Thanks for the info, I feel more enlightened on the subject.



So you would suggest that for a PSU? That exact one is $10 cheaper at a store quite near me... I was looking at the corsairs, and more specifically the HX series. Would I be really missing out on anything if I went with a TX PSU vs an HX from corsair?

Edit: http://www.canadacomputers.com/product_info.php?cPath=33_443&item_id=054107 Here's the link. If I am reading that right, does this not support Haswell chips or something? Or is the title on newegg just exaggerated for sales?

Thanks.

i think hx series is modular meaning there's cable management and yea i would lean towards good branded psus like corsair maybe not specifically that model if you are wanted to save a little money by dropping to a lower watt one
