Reminds me of my Corsair grey label CX750M where the inductor cooked itself.

I replaced a corsair 850w this month.

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

u/Ur_mum 20h ago

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.

3

u/LaDmEa 12h ago

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)

u/NeoCGS EndeavourOS | 5900X | RTX 3080 | 32 GB 3600 MT/s 9h ago

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 😭

1

u/LaDmEa 7h ago

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.

1

u/NeoCGS EndeavourOS | 5900X | RTX 3080 | 32 GB 3600 MT/s 7h ago

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.

u/Aw_geez_Rick 23h ago

Had this exact same thought... Couldn't remember exactly what I had because it's been so long and my PC has a shroud over the PSU but thankfully the box doesn't 😮‍💨

Safe... I hope 😂

19

u/ShortHandz 22h ago

The PSU in question is the older green labeled CX PSU's. I believe they got better with more recent iterations getting less... Explodey?

2

u/Schwarz_Furumoto 21h ago

Oh shit I think that's what I have on my build lol. At least the name is the same CX-750M but the box is yellow not green. Should I be scared?

3

u/ShortHandz 21h ago

Not a great PSU, but that sounds like a second or third gen model that was less prone to exploding.

1

u/Schwarz_Furumoto 21h ago

Thank god lol

2

u/Aw_geez_Rick 21h ago

Can confirm genuine IT term: "explodey" 👍🏻

u/Foxy_Psycho 22h ago

I used one for 12 years no problem, still works. The main issue is you never want to cheap out on a PSU because if it does fail it will kill the other more expensive components attached to it.

u/bigbassdream 9800x3D-5070TI-32GB DDR5 22h ago

Yea same lmao

1

u/Relative_Claim6178 21h ago

I also had a CX750M until I got my most RM1000x. I got tired of certain games causing instant power-offs. Playing HITMAN WOA with my RTX4070 and High settings and Nvidia Reflex + Boost seemed to be too much, but if I turned off the Boost, the CX750M would be able to handle it. Now the RM1000x handles everything.

u/modal11 PC Master Race i5 10600K/Z490/32GB DDR4 3200/GTX 1660 20h ago

If your part number is the older 75-002019 these are known to have issues.

If your model number is similar to CP-9020222 it is a revised version that is not affected by this issue.

u/Sarpool 19h ago

I looked at mine too.

But I have a TX750M

Had it since 2013.

Got damn I’m old.

u/SirAmicks 17h ago

I have a CX750 that’s over a decade old that’s still running great.

…not in my main PC, though.

u/tentegesszmeges 22h ago

thx, I've never have time to finish it /all fans are disconnected from rgb/ but, yeah i also really like it.

3

u/WeakAd569 22h ago

Is this a Jonsbo D32?

I've been deciding between that and the Lian Li A3 for a month now. Are the thermals? Were you running all 3 fans as exhaust? Or are those reverse flow fans?

2

u/tentegesszmeges 22h ago

Z20. 140 mm fan next to PSU is intake /its standard, just flipped/, rest /120 mm/ is outtake. Thermals are ok, IMO better that last case for this setup /corsair spec omega with grill mod/.

1

u/loneguy_ 13h ago

Is VS750D and this similar in design else you should be cool right

u/LuHex 23h ago edited 23h ago

Uh? That's weird... I've had the EXACT Corsair CX 750 fail like that, and it was the only time I've ever seen it in over 20 years of using PCs (and hopefully it stays like that). It was my spare/backup machine, which I hand't used in a while. When I powered it up it blew the fuse of my surge protector, then I replaced it (surge protector) for another one and the PSU lit up exactly like this video.

u/rips_n_chel 22h ago

It's almost like Corsair CX PSUs become a house-fire meme for a reason.

u/railbeast i7 12700k | RTX 3080 FE | Samsung G9 + D E C K 23h ago

I'm basically done with Corsair PSUs after I've had 2/4 fail within a year. A friend also had one fail.

u/Ok-Spot-9917 22h ago

Using corsair psu since 2011 1 hx 480 2 rmx 750 and 1000 never had any issues

The RMX ones are rock solid, really good PSUs

u/azrckcrwler 21h ago

Similar to me. I'm still running my Corsair AX1200i that I bought in 2013. Over 13 years of near daily usage as a gamer or various work purposes. I haven't paid attention since my PSU research during 2012-2013. Did Corsair quality drop or something?

2

u/placebotwo 20h ago

Using an AX760 here for 12 years so far.

u/TristanVE 21h ago

Literally bought a Corsair RM850x this week but after reading all these comments I’m legit getting a bit scared. Should I return it and buy another brand?

2

u/burnburn0303 21h ago

no, RMx is one of the best lineups

3

u/DrTuSo Ryzen 9 9950X3D, 5080, 64 GB RAM, 8 TB .M2 22h ago

I'm done with this shitty company in general. Build a new system with brand new parts, including a Corsair iCUE H170i Elite LCD XT AIO and a ton of other Corsair products.

System worked for 4 weeks, on New Years Eve, after pressing the power button, there was no display on the AIO and smoke started coming out.
The AIO caught fire.

The Corsair mouse was shit, the keyboard, their flagship one, is total shit and hangs up mid gaming.

1

u/BazarBS 22h ago

Same. I had 2 fail on me. One was 750 the other 1000+. Can't remember exact model. I believe former was cx something and later one was one of those higher end models. The 1000 took half the house with it when it gave up after damn near exactly one year of use. I make sure the PSU is of tip top quality now. Just makes sense to me.

1

u/Agret i7 6700k @ 4.28Ghz, GTX 1080, 32GB RAM 22h ago

I use Corsair RMX line in my high end system builds, they're super reliable unlike the cheaper ones.

u/Puzzleheaded-Flow724 20h ago

When the PSU used to have a 120V outlet, as a prank, I've put a radial capacitor across its pins so when my coworker turned it on, it would go "bang!" and smoke would come out of the back of the PC (from that destroyed capacitor). No harm to the PC and gave my coworker a scare lol.

u/FlamboyantPirhanna 19h ago

I’d say the terrorists won this round.

1

u/Broudison 16h ago

Lol this exact PSU gave up on me just few days ago. It survived for like 3 years

1

u/iAmGats 1440p 180hz| R7 5700X3D + RTX 3070 16h ago

You probably got the version 2. The spicy version was released in circa 2021.

1

u/Broudison 16h ago

Yup, i checkd the serial nr. It was not the exploding one. But i guess quality on that thing was bad anyway. Bought corsair rm850x now.
