My power supply is a generic 250 W (specs here:
http://support.gateway.com/s/PC/310_...00788sp6.shtml)

I have the following devices connected to the power supply

1. mobo (obviously heh)
2. 2 weak but quiet Case fans
3. cpu with heatsink and a fan on that
4. IDE hard drive (7200 rpm)
5. The SCSI HDD (10,000 rpm)
6. DVD burner/CD burner/DVD ROM combo drive



What is the best wattage for this type of configuration?

Please throw me a bone here.

Regards,

AR
