I have a custom Antec 350 watt PSU in my Sawtooth.

Things that are connected to the motherboard:

1.5 Ghz 7455B Upgrade
Flashed Radeon 9800 Pro
2 HDs
Fan controller with 4 extra fans
Wireless PCI card
USB PCI card

Should I get a bigger PSU? I don't want to wreck the one I have and especially not my mobo. Ever since I installed the 9800 pro I've been getting some weird symptoms like the keyboard is sometimes unresponsive and the clock seems to reset after every shutdown.
 
I think You're OK. I'm running a GeForce 6800GT, 3 HDDs, a DVD-RW, a Wifi card, USB 2.0 card, SATA card and overclocked 1.4GHz OWC G4 off my stock (vintage 2001) OEM Digital Audio power supply with no issues, and I belive it's rated at something like 338W.
 
I ran a Sawtooth w/the stock 200W PSU, a DUAL 500mhz cpu card overclocked to 600, and:

1) 4x HDD's, 2 of them 10k/74GB Raptors + 2 other 7200rpm drives
2) 2x 2port SATA cards
3) 1x 4port USB2 card
4) Flashed PC Radeon 9800/128mb, (plugged in to a molex connector)
5) Superdrive
6) Zip drive
7) 1x 3 speed, high output 120mm case fan w/ blue LED's
8) 2 extra fans, 1x 80mm, 1x 60mm

so I doubt you will have any probs w/ a 350w psu!

And yes the DA had a 338W psu as stock :p
 
If the clock is resetting after you shut down .... replace the motherboard battery.
They tend to cause funky problems when they go, but are thankfully an easy fix. Radioshack has them for <$10.
 
Digital Audio running:

1.5 Ghz upgrade
2 320G Seagates
1 500G Maxtor
1 IBM 36G SCSI
2 SATA cards
3 port USB 2
1 UW SCSI card
8500 Radeon

So far, OK.;)

BTW, Radio Shack robbed me last week... $14.99 for battery. :eek:
