Built for ATX 3.1 systems

This 850 W unit meets ATX 3.1 specifications and includes a native PCIe 5.1 12V-2x6 connector able to deliver up to 600 W to modern graphics cards. Japanese 105°C main capacitors and a single +12 V rail rated at 70.5 A provide stable power for high-performance builds. The 80 PLUS Gold badge confirms efficiency above 85 % at typical loads.

Modular flat cables simplify routing

A fully modular design lets you attach only the cables your build requires, reducing clutter inside the chassis. Flat cables with colour-matched connectors improve flexibility and make cable management easier. The package supplies one 24 pin ATX connector and sixteen SATA power connectors for drives and peripherals. No fixed cables remain when unused leads are removed.

135 mm FDB fan handles thermals

The Gravel Sand coloured 135 mm fluid-dynamic-bearing fan keeps internal temperatures low while adding visual accent. Active PFC and LLC plus DC-DC topology maintain tight voltage regulation across the 100-240 V input range. Hold-up time exceeds 17 ms at 80 % load, and the power-good signal arrives within 100-150 ms for reliable start-up.

Questions about this item

How much continuous power can the +12 V rail deliver before hitting its limit?

The single +12 V rail is rated for 70.5 A, giving up to 850 W for the GPU and CPU combined.

What is the fan size and how loud does it get under full load?

A 135 mm fluid-dynamic-bearing fan spins only as fast as needed; at 850 W load it stays within typical Gold-class acoustic limits.

Which cables must my motherboard and GPU already have to use this unit?

You need a 24-pin ATX socket on the board and a 12V-2x6 or 12VHPWR receptacle on the graphics card for the native 600 W PCIe 5.1 connector.
