Hi ALL,

I'm revamping an oldish server that ran 5 x 80 Gb IDE HDs in RAID 5 to now run 6 x 500Gb Seagate 7200.9 hard drives in raid 5 (on a Promise SX6000 6 channel caching raid card) plus a pair of 80Gb HDs mirrored for the system drive on the motherbards onboard Promise RAID. The Mboard is an intel server board running a P4 1.8 Ghz with 1Gb RAM and onboard rage XL gfx.

I noticed whilst building it, that the existing PSU is a delta 300 Watt and I decided it needs a more butch power supply, qusetion is how much power do 8 hard drives and a 1.8 Ghz P4 draw? Being used to speccing for high powered gfx cards and overclocked CPUs i have a feeling that its not going to draw more than 400Watts but I'm unsure...

any help apreciated,

Thanks,

E-I
