[thePh@r@oh]

im gonna be building a rig with 80GB HDD, floppy, CDrom, CDrw, P4 2.4A onboard video 512mb pc2100ram. will a 300 watt PSU be enough??

Yes, more than enough. What brand PS? One of those PS that comes with the cheap cases would be able to handle that.

Onboard video . . .

just found this might use it http://www.newegg.com/app/ViewProduc...ion=11-190-013

You don't have much of a load. I think a 250w would cover it if it were a quality PS like an Enermax or Antec. I'm running an integrated mobo with about the same load as you listed in your first post on one of my boxes with a mATX mobo. I'm using a 250w PS now but I originally had it on a 150w with no problems.

300w would give you more headroom though, if you wanted to add more stuff later like a Nvidia or ATI state of the art Video card.

The thing you have to remember is that not all power supplys are created equal. I purchaced one of Newegg's low end cases a couple of months back. It had a 300w PS but it was considerably lighter than my Inwin 250w.

Economy power supplys use lower rated components. The transformer and capacitors are smaller, thus the lighter weight. Also, they have fewer molex connectors to keep you from attaching too many devices.

The 12v rail on that PS that comes in the case you mentioned will handle 16 amps. An Enermax 350w will handle 26 amps.

The power supply in the case you linked to will fill your needs but I just wanted you to see the difference.
