+12V question

[MAXX RS4]

What's a safe range for my +12v to be running at? Mine has dropped to 10.88.

I know the +5v shouldn't go below 4.9v, but mine never went be 4.98v.

+/- 5% is the acceptable range. For the 12 volt line, you can accept as low as 11.4 volts or as high as 12.6 volts. For the 5 volt line, you can actually allow as low as 4.75 volts.

Now, my question is where you're getting those measurements from. Motherboard sensors can't be trusted to give reliable voltage measurements. You should use a multimeter or similar device to get an accurate reading. If you're using a multimeter to get those readings, let's discuss requirements for your new power supply...

10.88 = Bad.

Any more questions?

Seriously though, check with the multimeter.

Yea, I'm using a motherboard sensor. I'll whip out the voltmeter later today and see what that reads..

As I read in another post, someone mentioned that the voltage sensors are actually NOT all that wrong. It is the true value with the resistance on top so somehow if you add the resistance you will get your true total voltage values.

Still, you can't know how far off the measurement is without using an absolute measurement via multimeter or something. Thus, it defeats the idea of using the motherboard sensors simply out of convenience. Do motherboard readings make a good relative indication of voltage levels? Sure.

Ok. Well we can't argue that multimeters do the real job.
