Power requirement for HDs

[bastardman]

I have a lot of HDs, and I'm thinking of getting some more, but don't know if my powersupply can cut the mustard

my system;

420 Watt Thermaltake PS

1.4 Athlon
BFG Geforce 6800 oc 128mb
2 x optical drives
10 GB 7200
100 GB 7200
120 GB 7200
120 GB 7200
200 GB 7200
200 GB 7200

* Forgot to give PS

thanks

Seagate lists a max load for their drives of 33.6w, JSCustomPCs PSU calculator lists 25w. 25w is more likely average, the 33.6 would be peak.

33.6 watts is what it uses max. JSC is just an approximation to be used as guidelines only, not for specific components.

Exactly why I said 33.6 is listed as a max(for a specific family of hard drives), and the JS's number is an average.

those numbers seem high. ive run 6 10k rpm drives off my enermax 430. including the rest of my system. right now i run 4 drives off the same power supply. i know thats the absolute max, but it seems to me the absolute max would almost be attained at boot.

this is my boomstick!

Forgot to give my PS! 420 watt Thermaltake PS. So.. Around 30+ watts each HD? So like 180-200 watts for 6? That leaves me 220 watts for 1.4 Athlon (hopefully that doesn't use much), 2 optical drives, Hercules Game Theater XP sound, and BFG Geforce 6800 oc ...

Do you think I'm pushing it? And if I am, whats the worst that can happen? My PS dies?

 

[jihiggs]

if your power supply is worth the space it takes up your fine. theres no freaking way a hard drive uses 30 watts all the time.

this is my boomstick!

I've had 10 10krpm scsi drives in a dual PIII 550 xeon machine with a sparkle 300watt psu. You should be ok
