White ATX 3.1 power supply for modern builds
The segotep GM850 White delivers 850 W of continuous power through an ATX 3.1 compliant design. It targets system builders who need a clean white aesthetic and native support for current-generation graphics cards. Full modular cabling keeps the interior tidy and airflow unrestricted.
Native 12VHPWR cable and dual 6+2 PIN connectors
A single 12+4 PIN cable supplies up to 600 W directly to PCIe 5.1 graphics cards without adapters. Two additional 6+2 PIN ports cover older or secondary GPUs. Flat white cables simplify routing and improve case airflow compared to traditional sleeved looms.
80 Plus Gold efficiency at 850 W
The unit maintains greater than 90 percent typical efficiency across the load range, reducing waste heat and electricity cost. Active PFC and a 100 to 240 V input range ensure stable operation worldwide. DC-DC topology with LLC resonance provides tight +12 V regulation under heavy transient loads.

Questions about this item
Will the 120 mm fan need replacement after long-term use?
The 120 mm fan is the only moving part; under normal conditions it runs for many years, and a full-modular design lets you swap the unit without rewiring the case.
What protection activates first if the 850 W load is sustained?
Overload Protection triggers when total draw exceeds 850 W, while Over Voltage Protection guards the 12 V rail against spikes.
How loud and hot does the unit get when it runs all day at high load?
The 80 Plus Gold rating keeps waste heat low, and the Silent Fan mode keeps the 120 mm fan at low RPM until internal temperature rises.
