is it possible to use a second power supply to power an array of hard drives? my power supply is strained enough as it is, i dont think it could handle a bunch more drives. i am planning on using an at psu, the old style with the switch that turns on the psu directly.

i went to the tomshardware forums and all i got was this lousy signature.

Yes, you wouldn't be the first. Also if you got a full tower you can install it top of the original. Just make sure you turn on the PS with the drives hooked to it before the rest, or hook the two together so when you power up your original it turn on the second PS.

I could make that turn on with a 12V car relay, can draw you a picture with details if interested. No more manual switch! :)

You can find out <A HREF="http://www.burningissues.net/how_to/power/psu.htm" target="_new">here,</A> how to connect two PSU's in parallel.

that's 2 ATX not 1 ATX and 1 AT

The easy way to connect an AT power supply to an ATX not having to use the manual switch is.... (to me anyway)
Using a relay like the one people use for car alarms, fog lights, whatever else 12Volts, and the relay socket which comes with wires... Cost here under 5$(Ca) for relay and socket.

The hook up:
Mark the wires and cut the switch off the AT ps. (why keep that huge thing?)

1st AT ps switch cable to relay leg 30
2nd AT ps switch cable to relay leg 87 (these two you can mix up and nothing happens)

ATX molex positive to relay leg 86
ATX molex ground to relay leg 85 (do not mix these two up!)

<i><b><font color=red>Make sure that you got the right hook up before powering up the system!!!!</font color=red></b></i>
If there is a 5th cable in the relay socket then tape it up or just remove it. Ziptie the relay somewhere, hook up a 12V fan to the AT ps, power up your ATX box and see. If fan on AT ps turn on you did good, turn your system off and hook up your toys. Have fun!

You hit your ATX power button, your box start powering up, send voltage to relay, relay close the circuit and turn on the AT power supply. Your ATX ps supply power only to the relay to close the circuit and keep it closed till you power down, takes almost nothing. Pretty simple isn't it? :)

I'm not responsible if you get shocked, killed, or kill any of your hardware. Use your head.

If you decide that's too hard, then something like this might be good:

I think you could put many fans on this supply without a problem.

That thing is huge! A 550W Enermax is a lot smaller in size and nearly as powerful.

Yeah, and probably a bit excessive for just about everybody.

I like to find: if money were no object parts. That's what I consider this case. It could probably double as a fallout shelter though.

I do that for my car too.
