What's the normal range for a 12v rail to operate within? Something in my PC (which used the 12 volt rail) caught fire today, and after I got it sorted I checked Asus Probe, which reported the 12v rail pumping out 12.54. Is that ok? My googling didn't really help me : /

All relavent information is welcome. All jokes are too, if they're funny :D

assuming your motherboard is reporting it correctly that is straying more than it should. What brand is the power supply and rating? If the PSU is out of warranty it may pay to open it up and check to see if any capacitors are bulging or popped.

i think mine sits on that roughly.

PC caught fire is more likely dust buildup or something.


Did it damage much?

The PSU is an Antec 500W Smart Power 2.0, bought just 3 months ago. It was a little transformer for a light that caught fire. Lucky for me it only melted a few of its own wires and filled my room with smoke. I got a major panic at first though since it looked like it was comeing from one of my hard drives. I unplugged the PC in seconds though.

Ignore the ASUS probe.

Get out a multimeter and measure the voltages on the molex plugs manually while the PC is on. Just careful you don't short anything.

I reckon it would be pretty safe to say that it's normal....I wouldn't worry about it.

Cathode transformers actually have a tendency to do that.
