Do I need a bigger power supply?

[Hauk]

I've recently developed an issue where my PC reboots once at the the bios screen upon a cold powerup. I've check the memory with memtest. I installed a Gainward 5900 card a month or so ago, and I think the problem started then. The 5900 card needs that extra power connection directly from the P/S; and states a minimum 300W P/S is required.

I have:

An Antec 350W dual fan P/S
AMD XP 2600 oc'd a bit
512MB Corsair PC3500 oc'd a bit
MSI KT600 M/B
1 40G HD
2 CDRWs
1 floppy
sound card and modem

After the reboot everything is fine. But the no brainer leads me to believe I need a bigger P/S. What do ya think?

Got my eye on an Antec TruePower 430W from Newegg. Opinions?

You should be fine

What did you have in your computer BEFORE the Gainward 5900 card?

Old drivers "remains" could cause conflicts.

edit: my new 9800pro is a power-hungry hot-running monster (that raises my case temp by at least 12F); yet my 350w cheapie PS has no problem.

Your system isn't O/C'd, is it?
2nd edit: try backing OFF on your O/C . . .

that Power Supply is fine, for what you have in it.

On a Dell 350W PS I was running
P4 1.8
1 GB RDRAM
4 hard drives, 2 in RAID
1 CD-RW
1 DVD
floppy
Augigy 2
Wireless NIC

I did a fresh OS install when I put the 5900 card in (Win XP). Prior to that card, I had a Gainward Ti4600.

Hmm, what else would cause a reboot problem? I've heard the main thing could be memory...

It could be a card is upset about the slot that it's in. I had a dreadful case of the reboots that took forever to crack. My secondary video card didn't like being in the bottom slot.

Hmm... I did relocate both my sound card and modem when I did my OS reinstall. Was going for a cleaner look. That's worth a shot. Thanks...

SOLVED!

Turned out to be an over aggressive memory timing, and AGP 1 W/S had to be disabled.
Neither presented a problem running Memtest; so I was looking elsewhere.
Thanks guys...

P.S. My coolbits hack was kept getting reset to default clock speeds. That problem was solved too!
