Howdy,

I have a Supermicro SC-750A full size tower case I bought about 2 years ago. I'm planning on a massive upgrade of my old 433 Celery to a new Athlon 1.4GHz, along with upgrades to almost everything else as well.

The case has a 300W power supply, but I don't know if it's AMD approved or will be adaequate for the task ahead. It does fine in my current system, with 3 old SCSI hard disks, 2 SCSI CD-ROMS, and 6 case fans. The old SCSI hard disks will be replaced with a big new disk, but with the added load to the ps of the AMD CPU, and a GF3 card I'm wondering if I need to upgrade the power supply.

How hard is it to upgrade the ps in this case? (The last time I looked at a case's power supply it was years ago, and the ps was irreplacably bolted to the case.) What's a reasonable amount to spend on a new ps? Would it be worth shooting for a 400W supply instead?

Thanks!

Open your case, look at the brand and model number then check it against AMD's List of Approved PSUs.

If you case is a few years old, and you got it with the normal shipping PSU, then you probably have either a 300W Sparkle PSU, or 300W PowerMan PSU (economy Sparkle subsidiary), both of which are approved PSUs.

It would still be in your best interest to open the case and look.

Yeah I had an AMD system running in my 750A with the 300W Sparkle power supply, and its definitely AMD approved. Ran everything well, and a whole lot mroe as well

mine came with a sparkle.

i have a celeron2 on an asus cusl2-c and i replaced my power supply witha 430w enermax. why? because i have more drives than the sparkle could handle.

my drives:
DVD-ROM
CD-ROM
CD-RW
3 7200 rpm IDE drives
floppy

i realized i needed a new ps when i added the 3rd HDD. the system would not power on at all (unless i unplugged some things). so i used an at ps to power some components, and the system did turn on.

now i have a new ps =)
