Hello guys, thanks so much for such an informative forum. I have a quick question about PSU wattage:
How many watts must I have, and what determines this number for future reference? Heres the parts (New Egg):

- Rosewill R363-M-BK Micro ATX Black Ultra High Gloss Finished Computer Case with 400W ATX 2.2 12V Power Supply - Retail

- SAMSUNG Spinpoint F DT HD502IJ 500GB 7200 RPM SATA 3.0Gb/s 3.5" Hard Drive - OEM

- mushkin 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory Model 996587 - Retail

- AMD Athlon 64 X2 6000+ Windsor 3.0GHz Socket AM2 125W Dual-Core Processor Model ADX6000CZBOX - Retail

A good 400 watt PSU will be enough. However, the 400 watt Rosewill is not a good PSU.

A 300W Seasonic would be more than enough.

What video card do you have?
SLI or Crossfire?
Are you a hardcore gamer?
Do you overclock?

Well for the above config without a discrete graphics card, that 400W can handle it...
But like others said...it is a low quality powersupply and will not be able to handle anything more than your current config, mayb not even a slight overclock...
So better off buying a very cheap case + high quality PSU...

Mayb these...
Case -

PSU -
Preferably these...They can easily handle a ATI 4830 along with your current config...

Totals $70...
The extra $20 will give you a high quality PSU and a descent case...

Based on the informative replies, I changed the case to http://cmstore.coolermaster-usa.co [...] 766e3346dd and I changed the PSU to Rosewill Stallion Series RD450-2-DB 450W ATX V2.2.

Thanks :)

Rosewill is still a poor choice.

I disagree strongly. I do custom small-batch systems for businesses, and I commonly use just that case for office machines and other small systems. It does a great job powering most systems, up to and including Q6600 systems. I still wouldn't put a big VGA card in there, but for most things, it's just fine. As to rosewill in general, I have the new 700w single 12v rail PSU running my system with an i7 920 @ 3.7GHz and 2x 4870's in crossfire. It as stable as can be.
