I currently have 2 hard drives, an optical drive, and a 533 celeron running. I am about to add a 3rd hard drive and upgrade to a PIII 1 gig. I have a 250 power supply. Should that be enough or should I upgrade?

Also, when installing the 3rd hard drive, it will be on the same IDE cable as my optical drive. Does it matter in this case which is the master and which is the slave? I'm running Win2K, should that make any difference. Thanks.

Your current psu should be fine.

I would have the optical drive as master and the 3rd HDD as a slave.

I have a similar question.

My current system specs.

I'm currently running this system with an Antec PP-303X 300W power supply and I'm
wondering whether I could still use that after I swap in a Northwood 1.8Ghz P4, an
Asus P4S333 motherboard and 256Mb of Crucial PC2100. Although the PP-303X isn't
a P4 power supply, the Asus board apparently has some EZ-Plug thing that will work
with older power supplies.

Will my PP-303X be adequate, or should I pick up a new Antec P4 compliant PP-352X (350W)?

(Thanks in advance)
