Dual ATX power supply help

[cyberey66]

I recently bought a 300watt psu and want to use my old one for testing. Is there anyway that's possible. Can I put some switch on the connector that goes to the board?

you need to connect the green wire with anyone of the ground wires (the black ones) it should work.

Thanks much. I'll try that.

[anarki_gr]

try and let me know if it worked.

It would also be a good idea to ground out the PS-OK wire (grey). But, I have tested a power supply on its own with just the PS-On wire grounded out. I used it to power some hard drives.

I looked in my motherboard manual to find out which wire was ps-on, it was the green one. So I hooked the green wire to a ground and it worked.

Cool article, I was thinking the same exact thing for running a dual psu. But I'm only gonna use it for testing.

Check it out i did what that article says. its real easy just go down to the shack and get the parts. also i used a bigger relay that can also handle AC so i can hook my pump up to it

peppy thanks for the link and I was about to give you a big BS for your sig until I got to the last phrase. OC 48 lol! you forgot the fibre channel drives in 8x raid 0!

to put it simply, get a paper clip and connect the green wire to a black one

If I ever get a full tower and a fun cpu I should have a reason to hook a relay between the two supplys and any other cooling I have.
