PCIE power down issue

[josh_27]

Hi guys i just moved my old psu and gpu from my old system into a new case with new cpu and mobo. 

 

I didn’t change any cables whatsoever and my gpu lights up and spins. However it’s giving me the “Please Power down and connect the PCIE power cables for all graphics cards” Error. I’m really frustrated and have been trying to fix it for the past hour. Only thing is that one of the PSU 6+2 cable splits into two cables so i end up using 2 gpu plugs from the same 1 pcie cable. I’m not sure if that’s the reason? but i don’t see how it’s not working when it’s the same exact psu and set of cables that i’ve been using for the past 4 years.

if the cable is eant to split it should work, you could change the power ports on the GPU if it matters what slot its in for some reason, or issue with either.

Not sure why you would get that message, do you have PSU cables going to nothing.

If you have more PCIE slots, try moving the GPU to the slot below, just to see if it works.

Hopefully not a bad mobo.
