New Corsair RM850X ATX 3.1 PSU is available.
Hi everyone, I recently bought a Sapphire Nitro+ RX 9070XT and needed a more powerful power solution. My existing 600W BeQuiet! PSU isn’t enough for the recommended 750W minimum, so I purchased a Corsair RM850X ATX 3.1 PSU from MicroCenter. After setting everything up at home—carefully avoiding any cables from my old PSU—I powered it up. The system didn’t start. When I pressed the power button, fans whirred but didn’t activate, and the PSU emitted a noticeable click. All fans reached maximum speed, yet the GPU stayed silent, RGB didn’t light up, and no game loaded.
I tried a few troubleshooting steps: completely disconnecting everything from the board—even SATA power and drives—and leaving only the 24-pin and CPU power connections. Nothing changed. The system remained unresponsive. Eventually, I connected the new GPU to my old BeQuite PSU, and it worked perfectly. This confirms the new Corsair PSU is faulty.
I’m considering sending this unit back to MicroCenter for a replacement or upgrade. I’m really disappointed with Corsair, feeling they skipped quality checks. These products are well-reviewed, but I wouldn’t trust them anymore. If Corsair isn’t properly tested, what else might they be overlooking?
Just because you received a DOA component from Corsair doesn't mean they're a bad company or their PSU selection is terrible. DOA parts are common across all brands and sometimes quality control issues occur. It could have been any other brand, like Sapphire or BeQuiet, that experienced the problem. You can always replace it or switch to another manufacturer if you prefer. Personally, I stick with Corsair RMx PSUs and have used over 200 of them without issues. I could have gotten a DOA part too, but it didn't happen. It was just a bad luck situation. Maybe consider a BeQuiet PSU next time.
Usually I would have, but their power supplies aren't available at MicroCenter.
Just a reminder. The damage might have occurred during shipping from the Corsair warehouse to the Retailer. It could also have happened in MicroCenter's warehouse. If they're not careful, someone could have bought it, damaged it, or returned it. Personally, I just purchased an RM1000 model (2024 version) a month ago and everything seems fine so far. That’s why my PSU tester kept beeping while showing -12v isn’t present. Lmfao. Not using the Asrock board yet, but I’ll check my front aux later.
I believe this situation might have come about by chance. The device could have been missing during transit or due to improper handling at MicroCenter, making it possible for anyone to end up with it. This time, the fault was on you. As noted, I currently have four 3.1 ATX power supplies, including one ATX 3.1 RM850x model that functions perfectly. Personally, I recommend replacing it with a new RM850x. It's an excellent, dependable high-end option. Sometimes things just happen like this.
Was die PSU in einer Plastikhülle? Sie haben immer noch einen -12-Volt-Strom auf der HXi, und es scheint nur Asus-Boards, die das verwenden. Der einzige Nachteil ist, dass deine Lautsprecher "knallen" oder abschalten, wenn der PC eingeschaltet wird, wenn du keinen -12V hast.
This is wild. I wish you luck but I'm not sure there is a whole lot someone can do if that's how you reason through problems. Do you expect everything 100% of the time to be perfect and failures are out of the question? You are aware that's not feasible by any company and never will be. Everyone has DOA products. Literally everyone.
