Power and Efficiency

The sakose RGB-850 is a fully modular ATX power supply rated at 850 W with 80 PLUS Gold certification. It accepts 100 to 240 V input at 47 to 63 Hz and delivers up to 90 % efficiency under typical loads. A single +12 V rail provides stable output for demanding components.

Capacity and Headroom

The unit supplies two 6+2-pin PCIe connectors and eight SATA power connectors for drives and peripherals. Its 170 mm length fits standard ATX cases with bottom-mounted PSU positions, while cables reach at least 500 mm for clean routing. Protection circuits cover over-voltage, under-voltage, over-power, short-circuit and over-current events.

Build Integration

A 14 cm RGB fan with intelligent speed control moves air through a honeycomb ventilation grille. Addressable lighting offers multiple colour modes for visual coordination. The fully modular design lets you attach only the cables your build requires, reducing clutter and improving airflow inside the chassis.

Questions about this item

Will the 850 W unit and its 20+4-pin main connector work with my older ATX12V 2.3 motherboard?

Yes, the supply is compatible with both ATX12V 2.3 and 2.4, and the 20+4-pin connector fits legacy 20-pin or modern 24-pin sockets.

How can I verify the 14 cm RGB fan and 80+ Gold efficiency are operating correctly after installation?

The fan spins under intelligent speed control and lights up in addressable RGB modes; 80+ Gold means it should run at 90%+ efficiency at typical loads.

Which cables come pre-attached in the fully modular box and what must I source separately?

The box includes the modular PSU, a full set of detachable cables — 20+4-pin, two 6+2-pin PCIe, and eight SATA — so no extra power cables are needed for a standard build.
