Wacky Rosewill HIVE 550w?

[Bubbleawsome]

I'm running a HIVE 550 with my 4670k and 770. (Both overclocked. The i5 hits ~90w and the 770 hits 106% power limit, then 85c, then throttles to ~75% power.) The HIVE is very highly rated in reviews.
Recently I used HWiNFO to check my voltages. Everything was within 2/10v of normal (3.3+ was 3.31 IIRC, 5+ was 5.2 IIRC) but the 12+ was running well into 13.3v. I took a quick chip into the BIOS and it was reporting 12.228v. Is this normal? I think HWiNFO was glitched, but I want to make sure.

12.228V is normal, and actually very good. The ATX specification allows up to 5% deviation, 12.228V is only a 1.9% deviation. 3% can be considered "tight" voltage regulation, while the very best units perform within 1% of the nominal values.

However, the BIOS reports a value when the PSU is not doing much. Generally, with lower end units, you'd expect otherwise stable voltages to approach unstable when loading the unit close to its rated wattage. But your Hive is not a low end unit and it should be capable of stable voltage regulation beyond what it's rated for.

Even in full load with the monitor and speakers the killawatt rarely pushes 390w, so it is in it's limits. I'll test more later.

Got a pic.

You need a voltmeter(found on every multimeter) to really see what voltage is being output, as 13.4 is well beyond spec. Red lead into the yellow 12V wire and black into a black ground wire. Sticking them in a free molex connector is probably the most convinient way to do it.

I suspect the software reading is incorrect, because voltage should be going DOWN as amperage goes up.

At what load is that, or is it idling? Is the result the same when idling and when doing something power demanding?

Don't have a multimeter. :/ Can't buy one either. :awe:

Full load on GPU. I think it is slightly lower on idle, but I'm not sure.
