[SOLVED] Power Supply Shutdown Loop ?

[ab92134]

It happens randomly. The computer will shut off: I hear the powersupply make a loud click (probably electrical bypass? It always happens when powering the computer on or off.), then if it wants to, it continues in a continuous loop of click-restart-click-restart-click. Sometimes it might regain strength and I can use the computer to have enough time to fix things. I've managed to have enough time to download for 12 hours, load a video game (Borderlands 3) use the highest graphical settings, run a benchmark, steady fps, components are being kept cool; computer can last anywhere between 12 hours - 30 seconds. I'm guessing there is a compatibility issue, or bios setting that can maybe help?

This problem started after putting in the newest GPU, especially after installing drivers too. And it just so happens 6 months before I built the computer everything was fine when I installed windows with my plain old gtx 660. And so far I have not noticed this PSU shutdown loop occur on it when I decide to take out the 3060 and retry things with the 660. I don't think it has shutdown yet when I was using the bios however. Just usually between turning on the computer after it hasn't been running for some time, or I walk away from the computer and come back to a windows recovery tool. Just to be clear the main issue is the computer shutting down all on its own, but the continuous loop is also worrisome.

CPU: Ryzen 7 3700x
Mobo: Asus TUF Gaming b550M-plus WIFI
Memory: Corsair Vengeance LPX 16gb 2x8 DDR4-3600 cl18
SSD: WD SN750 500gb m.2
Case: Fractal Design Meshify C

GPU: GTX 3060 12gb
PSU: Fractal Design ION+ 660w Platinum

Fractal's PSU manual says something about a C1E (Enhanced Halt State) or check the graphics card options, including "vsync" option. Also I notice a power supply idle control in the bios, along with many other settings, usually set to Auto. Not sure, but I'm pretty sure the issue is with the power supply and the graphics card.

Could be compatibility. Can't say I've seen a lot of Fractal PSUs in the field. A lot of PSUs struggle with Ampere cards for different reasons.

Is the PSU still under waranty?

If you're willing to try something, unplug the 10 pin from the PSU and pop out pin 4 (+12V sense) and see if the PSU stops acting up. This works on the Seasonic PSUs with a similar issue.

See page 6 of the manual for the pinout: https://www.fractal-design.com/wp-content/uploads/2019/06/IonP-manual.pdf

What does the 4 12Vse do?

What does the 4 12Vse do?

It's pin 4. On the 10-pin. It's a +12V sense.

Are you sure? Looked at that page and it says it's +5V VDC. Was lookin at page 5 sorry even while i knew it was at the psu side, so dumb.

Ah at page 7 it gives the pin out for the 10 pin, there it indeed is the pin 4. @ab92134 this is at the psu side, not the motherboard side.

The sense wires monitor the appropriate voltages, and most higher-end psus have them. Could consider them as supplemental to the protections package, kind of like how Asus uses Anti-Surge on some of its motherboards.

With the ampere cards and Vega cards especially, they have such high, instant transient spikes, that the voltage drops on the 12v rail are noticeable, the 12v sense sees that, and freaks out.

Seasonic seems to have its protective circuitry set just a little too tight, so that drop in voltage registers as an issue, psu shuts down.

Fractal ion+ OEM is High Power, but has a similar affect. Pulling that sense wire is similar to pulling a pwm wire out of the header, the fan just runs full speed, no 'off' pulse. So the psu doesn't see that intermittent varience in rail outputs.

Afaik. Could be wrong.

It's worth a shot.

Is there a way I can check for such electrical spikes on a program or something? Or is that already evident enough with the shutdowns. I've tried to take out pin 4 with a pair of staples but failed and put everything back in, I'm going to need to get a better tool
