Hi chaps,

 

New here and first post so please be nice 

 

I recently acquired an RM850 (2nd hand) to upgrade from my CX500 having got a new graphics card.

 

I have an issue however as when I did a test to make sure it was good, after plugging in the 24 & 8 pin CPU cables and a test fan via molex, the RM850 makes a single tick before what I can only equate to sounding like a breaker being switched.

 

It puts the board LED on to show power but powering on trips a breaker it seems and it fails.

 

I'm totally stumped. I have tried a different CPU cable (same result) and reconnected the CX500 which powers the system just fine.

 

Any ideas, MUCH appreciated.

Thanks a tonne

Hello carts60,

 

From what I understood the PSU starts when doing the paperclip test, but when you hook it up to your system it does not start?

Best regards,

Hey! So was there a resolution to this issue? I have pretty much that same problem, and have also done the paper clip test and passed. I also checked all connections and wires multiple times. Previous Power supply works fine I had actually put it back in and it's working right now. So do what do I need to do?
P.S. RAM LEDs turn on and the motherboard LEDs turn on but that's it.

Uh..

 

Are you sure the cables that you got with the RM850x are correct and are Corsair type 4 cables?

Well at first I used the previous cables that I had and nothing would power on so I switched out the cables with the ones that came with it and that's where I am. Also not sure about the type 4 or how to check.

What other cables? The CX500 is non modular. There are none that you could have removed from that and reused on the rmX

Sorry I had just quoted the other guy I don't have the CX500 my previous one is fully modular.

And what PSU was it?

How about we get some system specs. What in the original post doesn't directly relate to your problem? Did anything happen when you did the paperclip test? That PSU has a zero RPM mode. What did you attach to it for a load?

Seagate 750w 80plus gold is my previous one. With the paper clip test the PSU fan turned on for a few seconds and the case fan stayed on and working. Before I had ran the test I had everything reconnected and setup in my PC and after Putting in the new cables, since with the old ones there was no power at all to the pc, I had just LEDs on the mother board and RAM. No fans or nothing else working. I also have the click from the RM 850x after powering it up.

Seasonic? 

That uses different cables than your RMx. 

Spoiler

Look at the PSU side of the cables. Except the EPS connector, they're all different.

Since you used incompatible cables, it's possible that you killed some components. Try booting with as few parts as possible. I.e. CPU, CPU cooler, motherboard, a single stick of RAM, and GPU if your CPU does not have an iGPU.

Sounds more like there is another issue. There is a relay that clicks when you power the system on and off normally, that's not a breaker.

[LK The Oz]

well i did try less parts not that less but yeah

This.

 

You don't use Seasonic cables with Corsair PSUs.

 

You don't use EVGA cables with Cooler Master PSUs.

 

That's why the RM850x says right on it:

Wait i literally don't know why i said i tried the other cables when they didnt even fit correctly so I had only used the ones it came with sorry i had told u i tried it as powering it on with them. Sorry for the confusion...

just keep in mind... in this forum, when a Corsair PSU is faulty, users are blamed first. (often till the end)

If a Seasonic PSU is faulty, people jump right to the conclusion that PSU is bad to begin with.

 

Which is weird, if you look at the Newegg rates, Corsair gets 4 eggs and Seasoncs are 5.

fyi, Newegg reviews were considered legit evidence for the WD 3TB drive lawsuit. 

 

edit: it was Seagate... instead of WD

Don't turn this in to a fanboy argument. They said they used their Seasonic cables with the Corsair PSU, which obviously won't work. People would say the same thing if they tried using a Seasonic PSU with Corsair cables.

Corsair cables will have "type 4" printed on the connector on the end that plugs in to the PSU. Only use cables that are labelled type 4 with Corsair RMx. 

Take the PSU and all the cables out of the system and make sure the only cables you are using are the Corsair type 4 cables. You might have forgot to change one over from when you were using the seasonic cables.

I think they do actually fit, so it's possible you are using some Seasonic cables with the Corsair PSU.

 

After you've double checked the cables if it still doesn't boot let us know and we can go from there, though as Seon mentioned if you did try to power it on with the wrong cables it's possible you have damaged something.

Okay I will get back to you guys on this since i had put the other PSU in my pc i might just put it in my wifes but we need ram and ssd and then ill know for sure if it works but thanks for the help guys! Talk soon!

I was not referring to the cable mismatch responses in this thread. I was referring to the responses of this forum in general.

I can quote some examples if necessary but it does not take a lot to figure out what I was talking about.

not true. Seasonic psus have a lot f problems right now, so they are easy to blame, no one should really buy them right now atleast. 

Higher end corsair psus do not have any major problems, so they are harder to blame, that is how it goes.

 

if you had to choose between 2 cars, 1 is good, 1 has issues and YOU choose the bad car, well of course we re going to blame you for buying crap.

If you use the DC cables from a different PSU with your new one, be it Seasonic, Corsair, EVGA, whatever. Then the blame is on the user, it's one of the simplest and most frequent user errors. Nothing to do with 'people on this forum'.

 

By using the incompatible cables, the user likely just fried their hardware, so even if swapped to the right cables after, the PC wouldn't work either.
