Compact Platinum ATX 850 W

This 850 W ATX 3.1 power supply carries Cybenetics Platinum certification and a native 12V-2x6 cable for PCIe 5.1 graphics cards. The unit measures 125 mm long and uses a fully modular ribbon-cable design with a 120 mm fluid-dynamic-bearing fan. All cables detach for clean routing in small builds.

Builders who need 850 W in tight spaces

The short depth suits compact cases and sandwich layouts where standard-length units will not fit. Platinum efficiency keeps heat and noise low under load. Builders who require multiple 12V-2x6 connectors or higher wattage for multi-GPU systems should look at larger or higher-capacity models.

125 mm length

At 125 mm deep this power supply fits cases that reject longer units while still delivering 850 W on a single +12 V rail. The dimension is the deciding factor for small-form-factor compatibility.
