Hi all. I currently have an Antec Sonata III case with an included 500w psu. I have had issues with the front USB port and am going to get a case with better cooling. I might as well upgrade my PSU while I'm at it. I'm looking for recommendations for a decent PSU that will supply enough power for my rig plus a decent OC. I may end up upgrading the GPU sometime in the future, but will probably never crossfire my gpu's...

what will be connected to the PSU:

Asus P5KC mobo
Case (tbd - Rosewill challenger maybe?)
8 gb DDR2 gskill rAM
tuniq tower cooler
HD5770 1gb gpu
several USB devices (wacom tablet, externat HD, headphones, mouse, etc)
Q9300 cpu

Any suggestions for a decent PSU that will supply enough power and then a bit more accounting for a GPU upgrade? I want to stay under $75....

Thanks!!!!

I'd say you'd be good with a 500 or 600 watt Corsair. If you go basic, you'll be under your budget. If you start going modular or semi modular, the price will jump up.

Corsair CX430v2 or Antec NeoECO 400C.

Yanks, I have no idea what modular or semi modular means... Sounds like Corsair is a good trusted brand though.

Pahedrus, will 400w or 430w really be enough?

Absolutely, got something similar running off a Delta Electronics 350W. Has to be a quality 350-430W like the ones I mentioned, but the wattage is more than ample. 100W CPU, 100W GPU, and 50-100W for everything else.

Phaedrus, what do you make of this? Says my HD5770 needs a 500w minimum. http://www.guru3d.com/article/radeon...review-test/11

this suggests anywhere from 160-200watts eaten up by my processor...

http://techreport.com/articles.x/14573/15

how did you come up with 100w for cpu and 100w for gpu?

Well Guru3D aren't PSU experts. They're good with graphics cards, but not PSUs so much. The HD5770 consumes 80-120W.

As for Techreport's article, that's for a different CPU. Plus that's whole-system power consumption at the wall, so that's all the other parts in the computer plus the inefficiency of the power supply.

Your GPU has been measured at the PCIe cables and slot at 80-120W, and your CPU has a TDP of 95W, and in normal usage pulls far less than that. Everything else shouldn't go over 50-75W. So 250-275W max.

If you scroll down the techreports article...it does list the Q9300. But didn't realize that was for everything. Why would the 5770 say I need a 500w PSU minimum? What is the disadvantage of getting something bigger than I need other than price?

on other thing i should have mentioned...there is a chance I may need to put my 6950 2gb in the computer should something happen with my sig rig. BOth of these are used for our photography business...and a little gaming How does that affect your recommendation PHaedrus?

AMD says the 5770 needs a 500W because they're assuming that at least one person will pick a bottom of the barrel 500W that is actually a 250W-300W.
