Enermax platimax, please check my new voltages !

post #1 of 14
Thread Starter 
Ok, so i bought a Enermax Platimax 850W, installed the PSU, (also i've done a great cable management with this PSU). So i installed the PSU, powered up the PC, and thank god the PSU is not making coil whine noises, it's silent, and the fan too, soo silent fan for a ball bearing fan.

Ok, so now i checked the voltages via software, and could please tell me why the +12V GPU voltage is so big ? Check the picture below.

Also, i had in the past a enermax revolution PSU and the +12V GPU was also big, why is that ? This is normal on a multi rail psu ?

A am using the native power cables which comes from the PSU, for my GPU,

    While the 12v rail (both of them, actually) are somewhat high, 12.2v is certainly within the spec (11.5v–12.5v).  I believe that those voltages are intentionally high so that they won't go too low under load.  My guess is: If you run a CPU and GPU intensive game, those numbers will go down a little bit.  When it's idle, your rig probably uses 80–180 watts.  When the load on the power supply is that low, the voltages will be higher, since it's designed for a load 4–9x higher than that.
    Also, due to calibration (or the lack thereof), those readings are not going to be 100% accurate; most likely, they are within, say, +–0.15v.

    Unless you start experiencing spontaneous reboots, or the computer switching itself off, I wouldn't worry about it.  thumb.gif

The 12.144v is still in 1.2% of it's nominal voltages. Seeing such value is safe and nothing to worry about. One thing you should know is that voltage monitoring tend to be highly inaccurate, in which you would want to use a DMM.

Actually the 12V GPU in load (games) drops from 12.234V to 12.134V
And the 12V drops in load from 12.144V to 12.056V

And the changes in idle on the 12V is 12.144V and 12.054V, most of the time stays at 12.056V

Hi as been said most software monitoring is at best vague at worst total pant's.

I used the Asus probe 2 and had speed fan running it told me my 5v was 3v then dropping then the stupid programme froze so stuck the multimeter probes on a 5v line and stayed @5v just dropped by .03? or something little.
One of the best investment any person can get is a decent multimeter.

Software monitoring is ok for if you see each time your on the pc so say you see it for 7 days and say's 12.3v then one day drops or is higher then that can give you a bit of a warning to check with meter to confirm before you do any damage!.

At idle volt's isn't too critical it's when under load that it is as if volts drop the amps get too high or if high can over drive components.

Plus as you have found it's ok you can also get those gadgets that give you a read out ive the digital one reading led dot/dashes wasn't really my think? give the full readouts for most cables.inc power good

Now i checked again my 12V GPU and now in idle says 12.234V and 12.250V
When i bought the PSU, said only 12.234V in idle. It's possible over time the voltage to increase ? Or i missed the 250 value from the first time when i looked into voltages in aida 64 ?

I'm not sure if you're following the responses that you're getting, but that software voltage readout is worthless. Period. If you're concerned with what your voltages are, buy a multimeter.

If you have an empty pci-e connector on the same rail as the gpu, measure that with a multimeter. If you don't, then measure another one, it will be within an insignificant margin. So will any other 12v wire you measure, for that matter.

Just start the PC and plug the multimerer wires into the connector, and it will show the volts ? It will do nothing with the PC, shutting him down or whatever ?
