Cooler Master packs a more durable, cooler running 12VHPWR cable with their newest PSUs

Cooler Master’s pairing their new GX III Gold power supplies with enhanced 12VHPWR connectors for improved safety

With their newest power supply, the ATX 3.0 compatible GX III Gold 850W, Cooler Master are giving their customers a new “durable 90-degree 12VHPWR cable” that is designed to be cooler running, and more durable than standard 12VHPWR cables. 

Cooler Master’s new 90-degree 12VHPWR cables use connector pins that are 25% thicker than standard 12VHPWR connectors and feature four total contact springs. This is two times as many contact springs as standard 12VHPWR connectors. With these changes, Cooler Master says that their connector is 5 degrees cooler running than standard 12VHPWR terminals, requires a 12% higher withdrawal force, and has an impedance change rate that is 45% lower.

These new 12VHPWR cables from Cooler Master aim to give users “improved safety” and “lower temperatures”, with the cable’s 90-degree bend preventing cable wear from tight bending. 

With 12VHPWR connectors being famed for melting when not connected properly, it is great to see that manufacturers are doing what they can to improve the standard. Let’s just hope that all future PSUs with 12VHPWR connectors will have similar improvements implemented, and that PCI-SIG’s planned 12V2x6 standard, which will likely replace 12VHPWR, will force some of these design improvements on all cables of this type.
