XP install shutting off power during install

A most bizzare problem. During the install of XP on a new SATA drive, the power will keep mysteriously turning off like the cable was pulled from the power supply. I can make it through the install process up to the point of setting up the system files. It will load, format the drive, and then bring up the screen saying that the system files are being written to the drive. Sometimes it shuts off power immediately. Other times it makes it up to 30% complete.

So is this a MB, memory, processor, drive, powersupply, or XP problem?

System is all new parts: MSI K8NGM2-FID motherboard, AMD 3700 San Deigo core, 2GB Corsair Value Ram, and a Seagate 250GB Sata2 drive. System temps are normal, and it can sit in the bios page for hours without a rise in temp over 90' F. 400W AMD approved powersupply has been in use for months without problems, and works with sepparte motherboard.
 
It is the COOLMAX CX-400B ATX v2.01 400W. It has great reviews on Newegg, and it has seemed to work on my previous system without a hitch. But nothing would surprise me at this point. My question is, why would a powersupply (or any hardware device) choke at the same point during the windows xp install??? In the bios, the powersupply voltages seem fine, and the processor stats are great. This is really bugging me!

 
Because a power supplys wattage rating is only a small part of what makes a good power supply good. Having clean power go to your system is very important and can affect stability. The actual output the ps has can also affect how many components it can support and how much power those components can require.

Coolmax is not known for quality power supplies and looking at the reviews on newegg don't look to good to me.

This is an older article but the basic information you need to know is there.
