Corn Electronics 850 W Fully Modular Power Supply White

850 W Fully Modular ATX Supply

This 850 watt fully modular ATX power supply delivers gold-rated efficiency for high-performance desktops. Builders who need clean cable routing and strong single-rail 12 V output will appreciate the flat modular cables and Japanese capacitors. It suits gaming rigs and workstations that demand reliable power across modern Intel and AMD platforms. The white finish fits colour-coordinated builds without compromising function.

Thermals Noise and Power Draw

A 140 mm hydraulic bearing fan runs under automatic speed control, starting and stopping based on load to keep noise low during everyday tasks. Active PFC and >90 % typical efficiency reduce waste heat at the wall, while the 100–240 V input handles global mains without a switch. Protections including OVP, OCP, UVP, SCP, OTP and OPP engage quietly when needed. The unit draws up to 10 A at the inlet under normal operation.

Sustained Load Behaviour

Under continuous demand the LLC resonant architecture maintains stable voltage regulation across all rails. The single 12 V channel supplies up to the full 850 W rating through four 6+2-pin PCIe connectors and eight SATA leads without rail balancing concerns. Japanese 105 °C electrolytic and solid capacitors support a rated MTBF above 50 000 hours. Fan speed ramps smoothly to match thermal load, avoiding abrupt acoustic spikes.
