hile owners of GeForce RTX 5090 class graphics cards nervously peek under the hood of their system units waiting for that familiar smell of burning plastic, hardware makers are trying to fix the mess they made themselves with the new connectors. Corsair has introduced the updated RM1200e 1200W power supply, featuring a built-in PinProtect system designed specifically to combat connector melting.
Real-time contact protection
PinProtect technology aims to stop the overheating of 12V-2×6 standard power connectors before it gets out of hand. The system continuously monitors the current passing through each of the six power contacts in real time.
"the new 1200W RM1200e implements PinProtect technology, monitoring the current at each contact of the power connector to prevent critical overheating"
As soon as the load on any of the pins crosses a safe threshold and stays there for a while, the power supply sharply drops the power on that line and forcibly shuts down the graphics card. You get a black screen instead of a smoking plug and a chance to calmly check the connector.
Reliability and price

The model has earned a Cybenetics Platinum certificate with a claimed efficiency of up to 91% and full support for the current ATX 3.1 and PCIe 5.1 standards. Inside, you'll find Japanese capacitors rated for operation at temperatures up to 105 degrees Celsius, while the chassis itself has been shortened to a depth of 150 millimeters—available in your choice of black or white finishes.
The RM1200e power supply costs $204 on the market, and the manufacturer backs that price tag with a ten-year warranty.
The bottom line
For $204, Corsair offers a 1200W power supply with contact melt protection that will kill your graphics card before an expensive connector goes up in smoke.
