Power Supply, 12v line
Good afternoon! I have a power supply installed, 1STPLAYER NGDP, 750W, 80+Gold, ATX3.1 (HA-750BA4). The rest of the hardware: Gigabyte B760 GAMING X, 12400f, 3060 Asus 12 Gb OC. The Aida64 program shows the idle voltage on the 12v line, 12.240v is stable, and already under load, in games the value changes to 12.096v -12.024 v. Yes, I know, and you don't need to tell me that you need to measure with a multimeter and this is the most accurate of all methods, but please let's make do with what we have. Is everything okay in this case? Thanks!

Its safe. If its 12.7 or 11.4, its already unsafe.

Whats Power Supply, you have?

in bios it should also say
some monitoring software is incorrect or needs offset values

the software for the mobo model from the mfg should read correctly

but atx spec is +/- 10% which is pretty wide
12v, can be 13.2 to 10.9

but if the psu cant hold the 12v rail within 0.25v its not a good sign

Nah, it was -5% ~ +5% with ATX 2.4 and 2.53, with ATX 3.0/3.1 it's -7% ~ +5%-.
10% for 12V rail was like 30 years ago.

11.16V-12.6V for OP's PSU.

^ this, IIRC it has been +/-5% since the AT spec in the 80s more than 40 years ago.

Hmm...
PCIe Voltage Deviation

No Requirement


No Requirement


-8% ~ +5%


-8% ~ +5%


did anyone miss the fact this is a listing for the 12 volt rail......by OP first post its well with in limits and should be fine.....

It works, I have no doubt about that. Why did I start to look at this, so after I wiped the system unit from dust with a slightly damp cloth, and touched the power supply cord near the power supply socket with a little cloth while working at the PC
But realistic speaking you should really never be seeing anything on 12V going below 11.4 or higher then 12.4

The 10% + / - IS non-sense spec designed to cover the behinds of the brand makers. If you're finding a voltage out of line by 5% or more.... get a different PSU

But also keep in mind you DO have a higher tolerance range when you are using 220V at the wall as opposed to 110 since ever since ATX 2.x came out

It's hard to argue with you. As I said before, the reason for my concern is that so after I wiped the system unit from dust with a slightly damp cloth, and touched the power supply cord near the power supply socket with a little cloth while working at the PC
A damp cloth? You mean just the exterior of the PC Case / Chassis I hope.

Use a lint free cloth, like you'd use to wipe down a Car with. And apply some rubbing alcohol when you do it. The alcohol will kill static. Allow everything to dry before plugging it in and powering it on. But either the rubbing alcohol on the mix, everything shoild dry rather quickly.

If you need to clean the inside of the PC tower and such. For that you'll want a handheld blower with speed adjust on it.It's best to do that outside so you do not breath it in or fill up your room and indoor air with dust.

No, no, I just wiped the closed PC case with a slightly damp cloth, the top is on the outside, and in the upper part I have a PSU, and its mesh grille, which I also wiped, at that time the PC was on. What do you say?
Just don't use plain tap water. Use Iso Alcohol such as 90% or higher. It's safer, it cleans good, kills static and also dries much quicker
