Hey all,

Just installed my new AIO but now the pc doesn’t start.

Thinking it might be some shortage, I’ve disconnected the AIO and GPU but it’s still not starting. All that it’s doing is making a slight clicking noise followed by all the LED’s turning off and on again.

PC worked fine before installing the new cooler.

Can we let go of the psu for now, the RMx series are very good. And yes of course you can even get a bad one out of those, but he got problems after adding the AIO.
Only thing thing i'm thinking of with the psu is that he didn't connect the wires correctly and i mean at the psu side, he wouldn't be the first that didn't push both parts for the 24pin in all the way.

Corsair RM is a terrible PSU with much better and superior alternatives, possibly it will be a PSU problem.

The RM lineup uses low quality capacitors that other Corsair models do not use, the 1000W RM lineup has failures of failing the OPP and exploding, I don't know if it happens in other models below.
But there is a high chance that RM units will come up with problems or have problems after some time.
First he has the RMx one on the best power supplies made, for the RM SERIES the 2021 model is also a high quality PSU

Don't make statements you can't back up!!!

And let's understand something that I just claimed to be a "bad PSU" because of the shoddy capacitors they use on these models. Let's differentiate things!

The problem is that most of you seem to have some commission or some kind of favoritism with the brands (
just with this and the rude way they talk to some users, it doesn't deserve a continuation of the conversation) anyone who talks about TOP brands having problems it seems like it's a crime or a kind of sin to mention they have problems, although that there are better alternatives. Not to mention that RM, RMX, RMI are a mid-range segment.
I will not recommend a product that most detect problems with units and that the brand dont wants to take responsibility, all brands have problems now people have to get used to it, you cannot create favoritism for brands.
Instead of asking the stores to return the PSU to solve the problem, they continue to resell.
Before coming here to comment I did research before that now I won't waste time doing it for you since you have this ability to do it. I'm going by the user's opinion and experience if a majority of units come up with problems and the brand doesn't want to admit it in public and stifle these problems with the RMA, it wouldn't be the first to do it, because Gigabyte does it with the Gigabyte P000GM.
"Don't make statements you can't back up!!!"
I'm not going to stop saying things just because most people are uncomfortable, here in this forum I've only encountered the same problems with the same PSU and I helped people with these same problems.

Depending on the value of the Corsair, as I said above, other alternatives from other brands are worth it. As with all models and brands I've come across, there are some people who buy certain PSU that end up having problems and others don't.

Just don't take it so seriously, calm down and relax. Have a rest of a good day.

Guys, always check the power supply first. It's true power supplies have internal protection but it's not always flawless. Also the supply might have crapped out when powering up something new that had severely depleted capacitors. This presents a quick but extremely heavy load on the supply. That's why they put current limiters on the supplies, However current limiters don't always work. I repaired electronics for 40 years full time. I couldn't begin to count the number of power supply I've repaired. You can blame things all day long on this board or that board and never get anywhere if the power supply has failed. The way the lights are flashing is a dead indication of the supply tripping and starting back up. However you'll never know what the problem is unless you divide and conquer. Separate the power supply and start it up. If you hear the relays kicking in and out with nothing connected to the supply it is not passing the self test and just shuts off then starts up and tries again. It can continue this process until it blows a fuse or something breaks down. They should sell power supply loads that simulate the load the computer imposes on the supply. If the supply works under load it's probably fine. Your next step is to connect the mobo by itself with no processor. If it starts clicking you still don't know if the supply is tripping under normal loads. But if it seems stable shut it off, and let it discharge. Next install the processor and see what happens. In other words work the load up. However without a test load for the power supply to test it properly I would change the supply with a knows good one or buy a suppler load test fixture. A good one is one that simulates a variety of loads , like 500w up to 1500watts or something but you get the idea. We had all that stuff in the repair shop. You guys are guessing and making assumptions. We had a saying, don't ever assume anything, it will come back to haunt you.

You might well be right, but only thing added was according to the OP the AIO cooler, cannot see how that brings load up that much that it makes a good quality psu crap out.

Other thing, it's not that we have the pc in front of us so a forum like this in the end always a guessing game. This is not a shop.

Another thing, the OP hasn't responded again so i t hink he has found the problem or maybe he thinks we're "just guessing" as well. I'm gonna wait till he shows up again after this post.

Sometimes multi layer circuits can short internally, Ive seen it happen. The power supply is probably just turning on and off when it senses an over current. Some supplies shut down and stay down until you power cycle them. Others shut down, then there is no more excess current to trip the over current sensor. Then they start back up only to shut down again. The flashing lights might be attached to the supplies, if so the supply is cycling on and off. The cooler pump puts pressure on the processor and the processor pins put pressure on the board. It's not likely the board has an internal short but it also not likely pump housing is shorting something. I think the pumps have a speed sensor that connects to the mobo but screwing that connection up isn't likely but if he did, The mobo might think the motor isn't turning and shuts down. But that won't trip the power supply from over current but instead it can turn the supply off. The power button doesn't connect directly to the two pins of the power supply, the mobo does. So basically if it's wire correctly, on the order of likely hood, I would suspect the speed sensor of the aio isn't working. If it were in the shop an oscilloscope could verify the pulses from the speed sensor. Ohm meters can check for supply shorts. Personally I'd contact the company who made the cooler. They may have others with the same problem.

Hey all,

Quick update, turns out the motherboard was faulty. Replaced that and the PSU (just to be safe) and all is working now!

Thanks everyone for the help!
That's cool, I suspected static electricity from the git go. Maybe it zapped your mobo. I don't think my aio even has a pump motor speed sensor though. Maybe the mobo had an internal short from the pressure put on it from the aio. I'd keep that processor and mobo for a little while though.
