RM650x (2018) cable doesn't go fully in

[empleat]

Hello,

 

i have problem with PCI-E undervolting. So i am trying to find out, what is the cause! Is it normal, that on RM650x (2018) outlet cable, part which goes into PSU, is sticking out and doesn't go fully in, in opposite of other PSUs? Also using 2 other cables for GPU. So that's not a problem.

 

BTW can i use iCUE to set the power to a SINGLE RAIL PERFORMANCE? This told me Nvidia support to do. But no device is detected in iCUE software.

 

Thanks!

Can you take a photo of that connector that doesn't fit completely just to have a better idea of the problem?

 

And you can't connect an RMX power supply to iCUE. Only the "i" versions do, through USB (RMi, HXi etc...)

Thanks for quick answer!

 

Hope it is enough, one photo wasn't best!

Although it does not look properly seated (are you using the kettle lead supplied with the psu?) I would think unlikely this is causing your issue. You can sometimes hear a crackling noise from the socket/lead if it was not home correctly, have attached a photo of my new TX850M. Check the socket for obstruction, and otherwise give it a firm push home.

 

If you suspect a poor connection it could be one of your outlet leads, or connections onto mobo causing pcie power issues.

 

Check all connections into the psu and onto your board, and gpu , especially the 24 pin and 6/8 connector, these can be a real pig to connect and is easy to have one not properly seated. As they are split plugs and all 3 supply PCIE with power.

 

Also check all pcie cards are seated correctly.

 

Could you post spec of pc, and a more In depth description problem please.

If by kettle lead, you mean default PSU to outlet cable. Then yes. I don't hear cracking noise. I can't connect cable more tho, it holds there firmly already. I know how much force is needed. And i pushed it normally in and it doesn't go further. I would have to use like extra large force at this point, i don't think thats it. In old PSU it went fully in, using same force, now it won't even move more, even to the side, not even little!

 

I don't think connection of cables is problem. As i built computers over 10 years and i know how to connect it and then it is secured. But gonna probably check all cables nevertheless... I will also check socket for obstruction, but this was since it was new and i read it is ok. But now i have problems so i was asking...

 

Thanks for the tips!

occasionally pieces of packing material can get into places you do not want but I have not seen many IOC cable problems over the eons since the PC surfaced back in 1981
