So you had 2 PSUs hooked up at the same time ?
I always wondered if that would work.
Can you post a photo of the damage ?
Two PSU's shouldn't be an issue. I think quite a few people who've OC'd their box are using two, me included.
Two power supplies can be bad mojo if you ever happen to have one powered on and not the other. Sometimes a power supply in the off state will short +12V to GND. If this happens while the other is trying to keep things at 12V, bad things will obviously happen.
can someone else also confirm this? adding another 600w psu is clearly cheaper than replacing with one 1000w+..
i wonder why they didnt make the avalons on proliant hot swap psu..

Could you not perhaps wire both PSU's to the same switch.
I used to run a shitload of hard drives in RAID on a cheap computer. Think 15-slot plywood drive cage with a dedicated power supply, 120mm fans blowing through the drive slots, and 36 inch IDE cables in a unholy mess to tie back to the main computer.
I built a box with a relay to trigger the power_on signal to the slave power supply when the master power supply was on. Radio Shack should have a suitable relay, either 5v or 12v DC trigger, negligible output current. Cut an ATX extension cable to connect to the slave supply, and cut any 4-pin molex accessory (splitter, fan power, SATA converter, etc) for the input. Bond the power supply cases together, either by rigidly mounting them in a shared metal frame, or by using a copper wire (and an appropriate crimp-on spade terminal if you aren't a savage).
For connecting the relay, you have several options. Bonus points if you etch and drill a PCB. This is an easy build, you can draw if freehand with a sharpie and the Radio Shack PCB kit. Second best choice is to use a socketed relay. Automotive relays are commonly available with pigtail sockets, from there it is just a few wire nuts to get everything together. Third is QC connectors. Forth is soldering directly to the relay.
Heh, if this is the case, i rather invest in a €100 psu and replace the one in it.
So it is kind of confirmed, if a certain psu model shorts 12v+ground, it might kill the entire unit?
Even disabling this shorting functionality might be too much for me and would make me just buy new psu..
