Need a server power supply

[Maxxarcade]

What kind of power supply do I need to run an Intel STL2 motherboard? It has a 24 pin ATX, 10 pin ATX12V, and another odd inline type connector. I'm only familiar with AMD stuff, so I don't know what that standard is called.

Also, I'll be running 8 320GB hard drives in RAID 5. Any recommendations on a suitable power supply for this system? It is going to be a file server with 24/7 duty.

I'm getting all the parts on Ebay except for the hard drives, because I'm trying to keep the cost down, so I'd like a PSU that is around $50-75 if possible.

Is this a good PSU for a dual PIII system with 8 hard drives? I don't think the 300W Sparkle I have right now is up to the task.

Actually this one has a very attractive price, and the +12V ratings are the same as a 400W unit.

EDIT: Looks like I'm going to need something pretty big. Each hard drive draws 2.8A peak on the +12v, so that's around 28A for 8 hard drives, a DVD drive, and a floppy

Well, the STL2 does like to have the 24 pin ATX, which just happens to match the latest 24 pin atx.. As for the 10 pin connector, IIRC that's for PSU management, and the 6 pin inline is an older standard more like 2000 era Pentium II and III series, server grade. It carries two +3.3's and one +5, with three grounds.. YOu can probably get away without using it, but if you can find a PSU that has it, it certainly doesn't hurt..


Any good PSU should be able to sustain at least 30% overcurrent on one rail for a period of at least 30 seconds with no harm to the PSU or reliability.. If you can enable staggered spinup on your drives, that would help a lot. On SCSI drives, that's really easy, but a bit more difficult on SATA drives...

Just bought a Zippy/Emacs HG2-6400P Looking forward to seeing what is inside.

It is rated for 30A on the +12v, which is about what I need. Hopefully it is worth the $80 I paid for it.

Oooh, nice.. I'd love it if Delta would actually sell to end-users.. Zippy/Emacs is good though. I'd love to have an ATX12V 600 or 700 W Delta to play with.. Given how nice their ancient 300W BB series is, when it comes to heft and cap quality, their 500+ W PSU's must be of legendary quality..

Probably not quite what you're looking for, but damn good for $30....
