low +12v on software reading of corsair hx620w

[fjorner]

i know that software voltage readings are unreliable, but let me ask this.

I'm running MSI's corecenter application and its telling me the +12v voltage coming from my just-out-of-the-box corsair HX620W is 11.72-11.78 idle. Speedfan says the +12V is hovering around 12.46V. Also, the 3.3V is 3.28 in corecenter and 3.07 in Speedfan.

I know I'm proving my own point here... software voltage is unreliable... but WTF ?

I'm thinking my PSU might be funny but without a voltmeter, how am I to know?

Well the corecenter numbers seem to be closer to the values they should be than what speedfan is telling you. Speedfan tells me my +12V is 12.25 and quite amazingly AVcc says 3.30 (I take this means the 3.3V rail). I don't have the same PSU as you.

Dude, your voltages are just fine. There's simply no way of telling your PSU might be funny, going by software read outs. Whip out the good old voltmeter if you want to know. If you don't have one, sit back and relax, it's pretty much 99% gauranteed that your PSU will be just fine, won't damage your PC, and isn't going to cause instability. Now, if you have been experiencing instability under heavy load, then you might want to check it out, but once again, those software read outs don't mean jack shit. In fact, your whole post is just kind of funny ...

ok.

my BIOS reading says 11.73 on the 12v rail. I have an msi neo4 platinum. Is the BIOS setting more or less accurate than all the software I've tried? Also tried everest trial, which also read 11.73.

I'm thinking I call Corsair support but do you think they'd grant an RMA based on this? I bought the PSU at CompUSA and with their bankruptcy discounting in effect, no returns.

I still have an 8800GT in the box that I'm terrified to install...

dood......whats the problem?

You cannot trust your bios reading or software readings.
Get a voltmeter and check it out if it concerns you!

I seriously doubt that Corsair would let you RMA your PSU based on software or meven bios readings!!!

lol cpu-z says my +12V is 3.46v, does that look correct?

btw it also reads:
vcore1: 1.33V
vcore2: 1.92V (wth is vcore2)
+3.3: 3.25V
+5V: 4.89V
+12V: 3.46V
-12V:-16.64V
-5V: 8.22V
-3.2V: 5.13V
Vbat: 3.14V

anyone see anything wrong with those numbers? PSU is a 2 year old FSP FX600-GLN Epsilon

Any reading within 5% meets specs, anyway, and decent digital multimeters are extremely inexpensive.

This thread is ridiculous. Wanting to RMA a unit based on software readings. You've got to be joking us.

One of many "why you should use a DMM to test rails" threads on the Corsair forums.

Ask Santa for a <$20 DMM, or simply take the psu to a local shop for them to test it. Unnecessary RMA's waste time and money for everyone.
