Power delivery for PCIe 5.1 graphics

This fully modular ATX12V unit delivers 1250 W and carries 80 PLUS Gold certification with up to 92 % efficiency. It includes two native 12V-2x6 connectors, each rated for 600 W, to support PCIe 5.1 graphics cards. The 135 mm fluid-dynamic bearing fan enables a zero-fan mode for quiet operation.

Cable reach and case fit

All cables are detachable, so only the required leads occupy space inside the chassis. The housing is 150 mm long and 150 mm wide, a compact footprint that eases routing and airflow in most ATX cases. Input voltage spans 100 to 240 V at 50 or 60 Hz for worldwide compatibility.

Protection and rail layout

Two +12 V rails feed the system, backed by OVP, OCP, OTP, OPP, SCP and UVP safeguards. Eight SATA power connectors are available for drives and peripherals. The embossed-jacket cables use premium copper-alloy contacts for reliable mating.
