I recently changed my server to MSI K8N SLI + AMD X2 3800+ cpu.
There's 4 ATA hard + 1 SCSI hard drive installed.
I also replaced power supplier with A-Power 500W and
it seems when I hook all HD and try to booting, I get long beeping sound
when it's checking bios and while loading windows 2003.

Sometime, power went off and rebooting at the login screen and
some times I could logon.

Doing detailed diagnosis, I found I'm not getting beeping when I'm only hooked
3 hard drives.. and I can't belive 500W power supply can't handle 5 HD.

Should I get reliable brand power suppier ?
