Hi. I'm new to these forums, but not to PC modding. I ran into a rather interesting problem the other day. My modded PSU killed two motherboards, as implied by the topic of this thread.
Everything was fine, until I modded my PSU to make it more attractive when used with my SwiftTech liquid cooling system. I chopped off all the molex and floppy power connectors, and rewired them so that one line had 3 molex and 2 floppy connectors(to run my DVD+-/CD-RW, floppy, vid card, and HDs), and the other had 3 molex connectors(to run all my case accessories). I also cut off the AUX connector, and sealed each wire seperately with electrical caps, which were tucked inside the PSU case. After I did that, I had to make a rather confusing mod to get the pump relay installed. My PSU, like many others out there, had 2 power plugs in the back of the thing. One male(where you put the normal power plug), and a female. I was going to take off the female one, and put another male for my coolant pump. The female plug had a transformer on the back of it, and both positives and negatives(one from each plug) went through the transformer before going to the rest of the PSU circuit. I removed the female plug from the transformer, being very careful not to tamper with the transformer configuration for the male plug, and I attached the male plug that came with the relay kit in its place. I connected the wires, as diagramed in the supplied instructions, and closed my PSU.
When I hooked everything inside my case (it was naked, because of the mods to the case itself) I filled and bled the cooling system, and went to turn my comp on. All the system and case fans started, the power LED came on, and the HDs started up like normal, but after that, the system hung. No beeps, no display, nothing. I pulled and tested everything in that case seperately, and everything but the motherboard is still in perfect condition. Since the board is still under warentee, I sent it to be replaced. In the mean time, I was using a secondary system, and it worked great. But, I decided to put that board into my modded Xazer2 case so I could use my Radeon9700 Pro(which had a GPU cooler attached, so it was a perm addition to that case), and the same problem happened. This other motherboard stops at the exact same point as my original(listed in my profile). My original one was deemed inoperable by my friends at my preffered computer store, and this second board is in the same condition. Any idea what could be causing this to be killing my mainboards? I'm still a but unfamiliar with PSU modding, so I read up a bit before doing what I did. By the weekend, I'll have taken my modded PSU to my comp shop and have them take a look at it, as well as hooking up a tester to it.
Any suggestions are welcome, and my appologies for the long message. *lol* Soon, I'll have pictures to show anyone who wants to see what I'm talking about.
