Some time ago, I had an Etasis ET750 power supply (essentially like a PCP&C Silencer 750, feature for feature) in my testing rig, gearing up to test an ASUS M2A-VM motherboard (based on the AMD 690G chipset). However, after about the seventh or eighth time I powered up the system, there was a loud pop and the smell of acrid smoke, and the PSU was toast. I discovered it had taken the motherboard's south bridge with it, as the system would turn on and POST, but refuse to see a hard drive. Etasis replaced the power supply after a while of trying to get in touch, but the review of that motherboard never happened. Sorry, ASUS.
