400 Watt PS

It should be plenty unless your running slaved hard drives and burners and a bunch of fans and lights and ....... But serously it is enough to run what you have listed.

i just made an upgrade ...bought the 36gb raptor, 320gb wd, corsair rams and enermax coolers...the problem is im getting random restarts and the minidump analysys pointed to the files win32k.sys, ntkrnlpa.exe. on a similiar thread i found that these could mean either that psu is not sufficient or ram-modules are not good.

also driver problems and cmos battery could need replaced a good bench mark testing software would help too ..
You can download a good utility for free at download.com to help pinpoint
the problem.
Also I am not familer with the new OS by microsoft but XP and 2000 PRO and 98SE I have only exployer loaded up at startup even my Anti viros I load manuly... Good luck

Use this utility and it will tell you how many watts a you need.

Also understand that the 12V+ rail is the most important in a computer. You might have a PSU that has 17A on the 12V+ rail, but you PC may need 20A on it. So go with a PSU that has at least two 12V+ rails. That way you PC won't undervolt and cause random restarts.

You'll be pushing the limits. Go for at least 450W or greater. Always add about 30% cushion for whatever you calculate - this also includes the degrade factor. ALL PSUs degrade over time due to capacitor aging. A 2 year old PSU loses 30% power if ran constantly due to aging.

Agreed, you'll need a little bit more to give you upgrading options as well.
