I am fairly new to computer DIY projects and this machine will become the first I built myself. However I am very skeptical that it will work flawlessly on it's initial run and to avoid $200 down the drain and a large paperweight, I want to ask someone who would be more experienced in this. Here are the specs:

Processor: Intel Pentium 4, 2.26GHz

Motherboard: Biostar G31-M4

Graphics Card: GeForce 8400GS

Power Supply: Pre-installed with a Logisys CS308RD at 480 Watts


So far, I have found that the Power Supply can easily pull the Graphics Card, and it should be able to do the motherboard, but I am still fearful of the outcome. Thanks in advance for anyone who can help.

Just as important as the actual 330W rating is the amount of +12V power the PSU can provide. It's the main voltage for your power hungry parts; CPU and Graphics cards, plus case fans, HDD fan motors, etc.
That PSU can provide 16Amps worth of +12V power. 16A*12V=192Watts - a really abysmally low amount for a modern computer.
Luckily, your parts aren't especially power hungry and your system's requirements are covered by that PSU.
Hello Northwestern;

Logisys has a habit of marking their PSUs with PEAK output power ratings instead of the continuous power rating nearly everyone thinks of as the 'true' rating of a PSU.

For example the Logisys PS550ABK 550Watt PSU has a peak output rating of 550W but only 400W continuous power. Most would say this is a 400W PSU.

In the case you're looking at I believe this is your PSU:
PS480D 480W and is from the same family as the PS550 above.
So far, I can't find a data plate of the 480W to figure out it's continuous power rating.
 


Yes, that is my PSU installed. I also looked on the box of the case I somehow still have and it says the PSU is 480W.
 
What does it say for Total Power?

Thankfully. I was worried more about the Graphic card being the main guzzler of energy out of all components.

I'd test-boot it right now but I don't have an operational CPU Fan so I'd be treading dangerous if I did. Thanks for all your help.
