Need more power?

[NeoMadHatter]

my computer is randomly going insane and restarting itself. it doesn't give me any warning. just goes powerdown and restarts. do i need a bigger power supply or what else could be the problem? i currently have an Antec default 300W power supply that came with my Antec SX830.

Plextor 24x10x40 CDRW
Maxtor 40GB 7200RPM HD
Maxtor 30GB 5400RPM HD
WD 80GB 7200RPM HD
LG 8x DVD Drive
Iomega zip100 ATAPI Drive
Floppy Drive
Maxtor ATA100 PCI Card
ATI All In Wonder Radeon AGP Card
Linksys LNE100TX NIC
DLINK DFE510 NIC
5 Panaflos fans
Asus K7M mobo with AMD 800Thunderbird
Hercules Game Theater XP Sound Card

Any ideas?

Your assumption is correct, I would try another powersupply first. See if you can borrow a 350+ watter. If you have NT/2K/XP look in the event view for errors.
