Per, I'm curious as to why they sell such a low wattage power supply. The "lamest" that I could find locally was 465 Watts for a system that I just built, and it had a plug for the SATA drive that I put in.
The powersupply was in a cabinet I'd bought a while ago, but judging from what's on offer today, it's in the same range. 350W, maybe 400W in a typical office cabinet. Anything more than that comes with the usual "gamers" tag, which I've always found to be only about marketing. The range for individual power-supplies seems to be from 500W to 1000W.
On 26 Oct last year I posted in a reply to Fred Miller a table of how to calculate how much wattage your PSU ought to be able to handle for the components in your system. The table I provided is: QUOTE As a guide, I have been using the following table to work out what sort of wattage "my" PSU should be able to handle: COMPONENT WATTS MOB 15-30 CPU- Low end 20-50 High end(1) 60-100 RAM 7W/128MB PCI card 5 Network card 4 Floppy 5 Graphics card- Low end 20-60 High end(1) 60-100 CD/DVD/RW 10-25 IDE HD 10-30 SCSI - 10K-15K 10-45 To the TOTAL watts arrived at using above, ADD 30% to arrive at the wattage needed to be handled by the PSU. (Note1: these figures are applicable BEFORE the latest dual-and quad-core CPUs and also before the latest high end video cards came into being. Check their tech data to see what wattage they draw.) While the above figures give you a ball-park figure for what wattage your PSU should be able to handle, it then becomes a matter of ensuring that you get a PSU which *will* be able to 'deliver' because many PSUs (including expensive ones) claim one thing but simply do not 'deliver' when it comes to the crunch.
