My Power Supply died while overclocking

[spitter]

Thought I had killed my motherboard. Added .1 volt to the cpu core and 300mhz to the cpu and it came back with a blue screen while loading window, no big deal, up the volts by.01 and it just gets to loading windows and the screen fades out. Start pushing delete to get back in the bios and realize there are no lights on, no fans on. Hit the power button, nothing happens, unplugged it and opened up the case and reset the bios, nothing happens, i was sure that the motherboard was toast. Wanting to find out quickly if it was, I found my repair power supply, a real cheap backup ps that works, plugged it in and the computer works. Never had a power supply die like that before, usually the slow death with alot of reboots. Anybody else have one die while overclocking???

prolly too much load on one 12v+ rail, 18A each is what you get on standard DELL 305W PSUs

18 each is the same as that bfg has. The computer is running better with this repair/backup psu, ppd while folding has gone up by 1500 since the other one died also overclocks better, and it only has one 11amp rail. Apparently the bfg was on a death spiral a few weeks ago and overclocking just pushed it over the edge.

Under powering your computer is a bad idea, it might work in the short term and not damage any of your parts. In the long term it leads to hard drive corruption and data loss and alot of bsods. Been there done that!! Reading the sticker on the dell psu the max output on the 12v rails is 22A and max total output of 305watts, sound like a good power supply but not made for a machine that requires pcie connections.
