Get the Seasonic Focus SGX650. I switched to that, works perfectly.

I also changed to SGX650, no issues. No other parts of my computer are affected *PHEW*

I don't think so. I swap to Seasonic 650 and it works fine after that. It might not be a Corsair issue per say but it is more of a batch issue that the current stores or in particular Dynacore stock.

I called Convergent up to do an RMA, they told me they don't have the stocks for RMA as they have placed an order since Jan and because of COVID-19, there is no stock left for me to RMA. So they recommended me to do a 1-1 with the shop I bought from which is Dynacore https://www.dynacoretech.com/. The one that returned might be from me for the initial set (returned from Dynacore)

Heh unlucky =(. I also can't RMA it, there is no RMA stocks in Singapore. Luckily it spoiled within a month and the shop was good enough to do a 1-1 for me. Is that for the first time or subsequent times as well? Normally my PSU has always been at the "on" position and I just turn on the wall plug.

When I did a 1-1 swap with the Seasonic and flip the switch, there is RGB lightning from the mobo. I have been switching it on 24/7 for 2 days and did not encounter any power trip. I have now switched it off now but remains plugged in for a day (so far). RGB lights are still on and no power trip. For the Corsair, when I flipped the switch to the on position, the PSU switch was already at the On position. The reason I mentioned that it might be a batch issue is because both Corsair SF750 causes my house's circuit breaker to trip. After changing to Seasonic, it hasn't yet *touches wood*. So I can deduce three things. 1. Removing all the power cables and re-plugging it in solves it (PSU change). 2. Batch problem with my shop's Corsair SF750 (???). 3. The difference in 750W vs 650W causes it to trip (unlikely).

Yes. That is right. But it only happens when I plugged my new desktop in. No other equipments causes that. I have an iMac at home that works fine if I swap it out.

I think my bad for using the word interchangeably. My assumption is that a power surge has happen and that causes my circuit breaker to trip. Sorry I have double checked. The RGB is coming from the mobo itself without the computer being switch on. 1. I plugged my computer to the electrical outlet, the outlet is switched on (In Singapore, we have switches on the outlet). 2. I did not power on the computer, but there are RGB lights on the mobo 3. In the above state, it causes my circuit breaker to trip (and hence I assume it is power surge). 4. It trips for three times. For the first two times, the RGB on the mobo still came back on after I flip back the switch of the circuit breaker 5. On the third trip, when I I flip back the switch of the circuit breaker, the RGB on the mobo went off (PSU spoiled) Computer Specs AMD Ryzen 7 3700X Asus ROG Crosshair VIII Impact Zotac Gaming GeForce RTX 2080 Super Twin Fan G.Skill Trident Z Neo Series 32GB (2 x 16GB) 288-Pin SDRAM PC4-28800 DDR4 3600MHz CL16-19-19-39 Addlink S70 2TB NVME SanDisk Ultra 3D NAND 2TB Internal SSD Corsair SF750 Lian-Li TU150 ITX Black Casing Arctic P12 PWM PST (Black/Black) Value Pack I am not using any custom cables, all of them are from the box. I went back to the shop and did a 1-1 for Seasonic Focus SGX 650W SFX Gold Modular PSU. It has been 3 days, and so far so good which makes me think is the SF750 issue (might be a batch issue).

Exactly, I am also confused with what happen. I didn't even switch on the PC, but it was plugged-in to the socket, so the default RGB lights on the AMD CPU fan is on, RAM RGB is on, etc. But the computer itself is off as in I did not press the power button to switch it on. That causes 3 trips. On the 3rd trip, the lights disappear and I knew the PSU is spoiled.

Original one died, could not power on. That happens when I try to switch on the PC and it trigger a surge. After that, my PSU is spoiled. Changed a new surge protector, RMA the SF750. Replacement came, also died. This time round, the weird thing is I did not even switch on the PC when the power surge happens.

Sorry for bumping up this thread. Chanced upon this from Google. I am in a similar situation with OP, just that mine is SF750. Original one died, could not power on. Replacement came, also died. The weird thing is I did not even switch on the PC when the power surge happens. In Singapore, power is stable, it seldom go out.
