[SOLVED] Why Does Plugging in 15 Pin SATA to D5 Next Pump Causes PSU To Stop All Power

[USMC7312]

I was cleaning and rebuilding my PC. After finally getting everything all cleaned and put back together, I started to have a problem with getting my pump powered.

So when I insert the 15 pin SATA cable into the back of the D5 Next Pump, it seems to result in my PSU cutting all power.

The power light for the motherboard on/off does blink green.

Has anyone seen this behavior before and know how to fix it.

I have tried new cable.

You have a short somewhere. Could be as simple as 1 drop of coolant in the Sata connection at the pump or one of the keys is misaligned or bent
