Hi,

Over the years, I've kept a few ATX power supply from old computers. Now,
I'm thinking about upgrading my computer and add more hard disks. The
problem is the current power supply might not be able to support so many
hard disks running at the same time. Instead of buying a new, more powerful
power supply, I am planning to use one old piece (350w) to serve the
motherboard, CD, and 3 hard disks, then another power supply (350w too) to

Do the numbers.
Only 8 should not be a problem, if it's a real 350W.

15W * 8 = only 120W.
Add another 100W for the motherboard, and you're pretty much fine.

Also.
You'll want to do the numbers on life cycle cost.
Yes, you may have 3 80G drives spare, that you can stick into a system.
If you're going to be leaving them on (which increases drive life), then
in some places, you'll pay for a new 240G drive in a couple of years.
