Yesterday I blew two PSU's on my machine. It's a Corsair box, and the first PSU was high spec (Antec 750W Gamer). The second was just a bog standard PSU.
Both blew in the same power point. I have a multi-meter stuck in it at the moment and have some suspicious readings. (I got over 700 volts for about 30 seconds yesterday. My meter is pretty old though, so I'm not 100% confident of the reading).
So, I have a few questions:
- Is there any possibility at all that my box/motherboard/machine could be causing the issue?
- Is there any way I can use Linux to monitor the input voltages? (I read a bit about lm-sensors but that just measures the output of the PSU. That could be handy, but what I really need is the input to the PSU.)
- What kind of protection should I be looking at? I haven't been a fan of this in the past because it seemed a minefield - you could end up spending a reasonable amount of money and still end up with something that was inadequate.
