The SSD and it's power requirements

Piggybacking off my SSD/BSOD post...

I was reading through some posts over at OCZ Forum and caught something...

I have all my drives... my Agility3 and 3 500GB Hitachi HDD's... all running off the same power cable. It sounds easy enough, right? Daisy-chain them all in a pretty row with less wiring clutter.

None of my drives are serious power monsters, but should I be running either just the SSD, or, alternately, the SSD and maybe one HDD off one power cable and the others off another? Or is the power draw nothing to worry about?

Just trying to figure out what's best for my build for the long run...

I would assume (including losses) a possible 40 watt peak draw on such "chain". Check your PS specs for the capacity per feed. I dont like to chain that many off one feed, but fact is, except possibly for start up, not all devices will be drawing max. power at the same time (eg, not much power use when drive is idle; most power used on start up then when writing).

The power is split between 12V and 5V. I'll bet the current through any single wire never goes past 2 amps in your setup. The wire itself can easily carry 5 times that much current.

Power should be sufficient for a desktop drive at each connector; you're using essentially a laptop drive for one so you should be fine.
