Question-11.68 regarding -12v — 14th PIN line
Hi there, your test results show a reading of -11.68 on the 14th -12v line, which is unusual. The other PSUs are showing correct positive voltages. Is this typical?
Thanks in advance,
Dustin
Make and model of the PSU?

I struggle to see the brand and wattage clearly without removing the whole unit. It’s good to know the tolerance ranges, so I’ll be printing this out. The customer reported the original board had a bad DMA controller, so I replaced it and now they’re complaining about restarts during games. I think the power supply is fine since everything stays within specs, but I’m thinking about replacing it with a new board if I can find one. It’s tough to locate older models in good condition. For another thought, maybe checking the temperatures?
Testing a PSU effectively requires more than just a multimeter; it depends on assessing performance under load. Proper evaluation should have started with checking the power capacity and quality to ensure suitability for the intended hardware, which demands understanding the PSU's specifications from the beginning.

It should work, though it might not be the top brand. Would you recommend a load tester for this setup? I don’t have one and plan to try swapping again.
It's not as bad as most Apevias, though some are quite serious. I'd still prefer to replace it with something reliable, just to avoid it. I'm sure it's usually in the "budget build" tier, not an i9 model. I often use my neighbor's old SunMoon; even decent entry-level load testers cost around $1500, making it a significant investment.
