I have a used Corsair AX1200i Digital Power supply. It was given to me by a friend. RMA is not an optional. When I hook it up to a motherboard it trips instantly. So I started poking around with it. I pulled out all power cables exept wall power and turn it on with a small piece of wire. It will stay on for 20 minutes to an hour and it will trip. Then I plug it back into the board and it starts right up. So I hooked it up to my main system and it turns on for about 3 seconds and trips. It has a self test feature that works somtimes. I can hear a clicking noise coming from the area near where the wall power plugs in. Its an expensive PSU so I dont want to scrap it. Any help would be much appreciated!

Re: Sick Corsair AX1200i. Please help!
The clicking noise when you power it up is from a relay, which bypasses the NTC thermistor once tit has done its job and allowed the primary cap to charge up more slowly. the noise is perfectly normal on this PSU.I love putting bad caps and flat batteries in fire and watching them explode!!
No wonder it doesn't work! You installed the jumper wires backwards

Hello everyone,
I'm encountering a frustrating issue with my Corsair SFX 450 power supply. After an undefined period of operation, my PC will either suddenly restart or, in some cases, it won't start at all until I disconnect the power cable and reconnect it. This erratic behavior occurs intermittently, making it difficult to pinpoint the exact conditions under which it happens.
For context, I have tested the PSU using an electronic load at 150W, and under those controlled conditions, it functions flawlessly. This leads me to... -
This found its way to my workbench this week.
Wired Wall Light Cam S100
The buyer thought he got a great deal but it turns out it was likely dead and the seller tried to get anything they could for it by passing it off on an unsuspecting buyer.
Rather than tossing it in the bin he gave it to me to play with as he knows how much I love to try to solve problems like these.
The camera portion of this device worked fine when powered via USB but when on the mains it would not work at all.
This reminded me of the eufy floodlight... -
The power supply is 2020 Corsair HX1200 modular power supply.
Cause of damage: I connected EVGA molex cable to the Sata port and test it with a ATX tester. Since the pin out on the EVGA is wrong, result in the 12V pin shorted to the 5V pin, in the 12V back-feeded to the 5v port.
Damage: Power supply shorted out, shut off itself internally, damaged the 5v or 3v rail or the monitoring circuitry. The self protection circuit shut off the power supply when power up because it detected some abnormal/defect. I waited a few minutes, let it self reset then try to re power up.... -
I have this Corsair VS450 PSU which lies dead and has an exploded TNY chip. Upon removing primary side parts like mosfets, the bulk cap and the bridge rectifier I've found that the primary cap is also a goner. (Photos)
The mosfets and the diode are fine and survived the collapse it seems. The TNY chip is shattered and from the online review/sources it was probably a TNY176~177.... -
Looks like I may need a little help from the PSU experts (or anyone really!
) I have a Corsair CX750M (Model 75-002019) that I picked up for free about 4 years ago. This is the PSU:
So here’s what’s strange about this one: it appears to work normally (normal output voltages) and any PC is stable with it. However, after a while (typically 10-20 minutes, but time can vary depending on the load), there is a sweetish smell of burned magnet wire insulation emanating from the PSU. Upon opening the PSU after this happened (many times), I was able to confirm...
