Most efficient PSU, slightly odd spec system..

blueacid · 17 Apr 2011 at 21:00

So I'm dusting some old hardware off to build a file server for my home, but would like an efficient power supply to go with. Noise isn't an issue.

So the spec:
Intel P2 @ 350Mhz, 512MB ram, wired NIC, PCI SATA adaptor (not hardware RAID)
Four 2TB Green SATA drives.

...I think I'll be needing around 100watts; would I be far wrong with that guess? What'd you recommend for this? Looking at the FSP120-50GNF as with a fan fitted that ought to be fine.
Equally, what about a 120+watt PicoPSU; would one of those swing this kind of load 24/7 comfortably? Or would that be a bit too optimistic?

Cheers,
Blueacid

I'll grab my electricity monitor back from a mate and see how much it's using.
I'm also going to email a couple of suppliers of Pico PSUs (in that OCUK don't seem to sell them) to see if they can advise me further as well.

Let's suppose that there's no suitable Pico PSU; what would you guys advise otherwise? What's the most efficient low wattage ATX PSU?
