Gundam-themed 850 W ATX supply

The ASUS 850G-WHT-GUNDAM is an ATX12V power supply rated for 850 W maximum output. Its fully modular design and white cables match the GUNDAM-themed case, stickers, magnets and lighting panel included in the box. The unit targets builders who want a coordinated white aesthetic with 80 PLUS Gold efficiency.

ROG heatsinks and 0dB fan mode

ROG heatsinks cover critical components to lower internal temperatures and reduce noise. The Axial-Tech fan uses dual ball bearings and a reversed centre-fan rotation for improved airflow. 0dB technology stops the fan entirely during light loads, keeping the system near silent. 80 PLUS Gold certification comes from 100% Japanese capacitors and premium components.

Compact 160 mm depth with full cable set

At 160 mm long the supply fits a wide range of cases while leaving room for cable routing behind the motherboard tray. The package provides a 24-pin ATX cable, two 8-pin CPU cables, three PCI-E cables with 6+2-pin ends, two SATA cables and two peripheral cables. All cables are modular so only the needed leads are installed. Input voltage spans 100-240 V for worldwide use. Protections include OPP, OVP, SCP, OCP and OTP.

Questions about this item

How do I route the 1000 mm CPU cables in a standard ATX case without kinking them?

Use only the length you need, keep bends gentle, and secure the white modular cables with the supplied GUNDAM cable ties so they clear the 160 mm PSU depth and motherboard 24 pin (20+4) ATX connector.

Which component should I check first if the fan stops spinning under light load?

The 0dB Technology keeps the Axial-Tech fan off until internal temperature rises; if it never spins under sustained load, the dual ball fan bearings or ROG heatsink thermal path may need inspection.

At what sustained load does the 80 PLUS Gold efficiency curve typically stop improving?

Efficiency peaks around 50 percent of the 850 W rating; beyond that the 100 percent Japanese capacitors maintain stable output while protection circuits OPP OVP SCP OCP OTP guard the rails.
