Hello,

I recently just built a new build and wondering what power supplies out there would be good for my setup. The one I am using now was my old setup, and I don't trust it.. even though it runs decent and doesn't have alot of problems.

Here is my build.

AMD X3 II 435
ASUS M4a78L-M
Kingston HyperX 2GB PC2 - 8500 (Going to add another one of these next week.)
WD 750gb HD 7200
WD 1TB HD 7200 (Going to add a 2TB also in the mix, within the next few weeks)
Nvidia 7600 gt (Upgrading it to a 9800 gt this week also.)

I think that should give you an idea.

Also, for some reason.. when I run cpu-z it displays my ram as pc2-6400. Wonder why?

Thanks!

The OCZ Fatal1ty 550W (by Sirtec) is a good unit for you for only 52$ (after rebate) in Newegg:

On the other side, the Corsair CX400 (by Seasonic) will work fine with your system, but you will need to use a molex-to-PCIe adapter to be able to run the 9800GT since this PSU presents only one PCIe connector. Apart of this, It's an amazing PSU for only 32$ (after rebate):

You can find qualified reviews about both PSUs in the "PSU Review Database" (see my signature)

A Corsair 400CX (30 amp 12 volt rail)

would probably work.

For a little more capacity, the Antec 500 watt BASIQ

The reason the CPU-Z reports your RAM as pc2-6400 (DDR2-800) instead of pc2-8500 (DDR2-1066) is that CPU-Z reads the contents of the SPD chip on your RAM.

Most DDR2-1066 RAM is simply DDR2-800 RAM that has been tested to run at the higher speed, usually at an increased voltage and more relaxed timings. CPU-Z is telling you that is what you have.

Henry, he said a 9800GT, so he only needs one plug. The PSUs that Jsc listed are good. I'd start with them.

Yes, you are right. The nvidia 9800GT only needs one 6-PCIe connector. I was mistaken.
Anyway, the recommendation that i did is plenty valid. The Corsair CX400 for single graphic card and the modular OCZ Fatality 550W for even two graphic cards in CF would be my choices.
About the Antec Basiq 500W (by FSP), is another option but It present less max. combined watts on the +12V output (348W) than the Corsair CX400 (360W), which makes it a worse option considering the price. Moreover, the internal built quality of the CX400 is better (japanesse caps in the primary included), it presents more SATA/IDE connectors,...

By the way, it's a bit strange that Corsair has decided to discontinue its production. There is no reviews yet, but the new CX430 (by CWT) seems not to be as good product as the old CX400. But this is the first impresion. We have to wait for qualified reviews to give an accurate opinion about it.

Thank you guys, very informative.

I started checking out, and I still think I could pick up a decent 9800 gt 1gb off craigslist on the cheap... but I was thinking I may see if I can find a 4850/70 instead.

If I go that route.. would these power supplies still be a good way to go?

Newegg has a 620w antec for $39.99 after rebate in today's promos. It has a single large 12a rating in the high 40's or low 50's. You have to be registered with newegg to receive the promos and for the codes to work. They also have a cable select ocz 500w with gigabyte 4550 video card for $34.99 after rebates. Finally, a gigabyte 9800gt for $49.99 after $30 rebate.

Awesome! I think I'm going to go ahead and order the MSI R5750, and the corsair CMPSU-400.. or should I just go ahead and bit the bullet for the Antec 620? I'm not to big on MIB's.. but if the extra money isn't worth it, that can goto my new 2tb internal. Ha.
