Power Supply for High-End Builds
This ATX 12V unit delivers 850 W of continuous power and carries 80 Plus Platinum certification for high efficiency. The fully modular design lets system builders connect only the cables required, reducing clutter inside the case. A single +12V rail architecture simplifies load distribution across demanding components. Conformal coating on the PCB protects against dust, stains and humidity up to 95% relative humidity.
Single +12V Rail Architecture
The power supply uses a single +12V rail design rated for the full 850 W, meaning all PCIe and CPU power draws share one large current pool. This eliminates the need to balance loads across multiple rails when installing high-wattage graphics cards. Eight 6+2-pin PCI-Express connectors are provided to support multi-GPU configurations or power-hungry single cards. Active PFC exceeds 99% power factor for clean mains input.
Fully Modular Cable Set
Fourteen SATA power connectors and the 24-pin ATX main connector are all detachable, freeing up space for airflow and cable routing. The unit measures 190 mm in depth, so builders must verify case clearance before purchase. An Eco switch enables fan-stop operation below 30% load for silent idle running. Protection circuits include OCP, OVP, SCP, OPP, UVP and OTP, with safety certification to UL 62368.

Questions about this item
What does the 850 W rating deliver inside a working PC?
The single +12 V rail can supply the full 850 W to graphics cards and CPU, so high-end components draw stable power without balancing across multiple rails.
How does the 80 Plus Platinum certification affect actual efficiency?
The unit maintains at least 90 % efficiency at typical loads, and active PFC above 99 % keeps power draw clean on the mains side.
Will the 190 mm length fit my case and what mounting does it use?
Standard ATX 12V mounting holes are used; measure your case clearance against the 190 mm depth before installing.
