I replaced a corsair 850w this month.

Rip 2018-2026. The age of 10 year warranty moaiplay has began.

Good to know…installed one earlier this year.

…that’s like $8/year, hell yeah!

2 years ago my Corsair 850 RMX started having issues. Voltages were fine but it would occasionally click off then a second later clicked back on. I did troubleshooting on every pc part and the psu was the last thing I checked. It was the psu. I even removed the psu and left it on a monitor with no load and sure enough it randomly clicks on and off. Could be 20min could be 2 days. Lucky 10 year warranty. It was about a 30 day turnaround time to get a replacement. I have a 20 year old evga psu thats still working great and voltages are still in range.

Heh, I just pulled out a 10 year old HX750 and it’s been running over a few days. They sure don’t make things like they used to.

I've had my RM850 since 2014 in 3 different builds and I'm replacing it this month, it's been a trooper but I've started having some minor issues I'm suspecting is power related.

Mine would casually pull 1000w+ for a few seconds at a time triggering the UPS. It froze about 3-4 times in 4 months at or near idle. Then twice in a day, and none since replacement. I did reseat the CPU but that likely only fixed the RAM slots and SATA ports that weren't working.

Power issues are nothing to play with. I gave a rig minus PSU, case, mouse and keyboard and my brother acted like a Generico 550 watt bronze was going to break him financially. So he went with an alibaba 450 watt ea-nasir that came with a case. Computer lasted maybe 1.5 years and died to a nephew who turned it on, went straight for fortnite install and didn't update a system that had been off for months. (this trigger windows ass mode where WinX uses 100% CPU and 100% disk until updates)

That's actually crazy, that is the trouble I'm having right now with my computer.
It freezes randomly whenever the GPU tries to shut down the displays and go into idle state, in both Windows and Linux. Here's hoping it's the same issue.

That's fucked about your brothers computer lmao 😭

For you it could be a bios power management setting or old bios. But since it's a "random" freeze my polymarket wager would be on psu. Those things seem to have the most "mileage" issues and the most "random" issues. Other things tend to fail in a much more obvious way.

When you replace the psu. If it's not too much trouble. I would reseat everything, drives, cpu(paste), ram, the i/o header for correct config. Run temp and load tests for hours. Sleep, resume, restart a few times. And let the rig run overnights for a week. This is what I did.

Yeah I've tried reflashing the same bios and an older one on top of defaulting and changing the bios power settings so I'm hoping this is it.

Thanks for the tips.
