  • Japan-made main capacitors and comprehensive protections ensure long-term reliability

850 W Fully Modular ATX PSU

This fully modular ATX power supply delivers 850 W of continuous power with 80 Plus Gold efficiency. It is built for mid-range gaming PCs, home-theatre builds or workstation upgrades where clean cable routing and stable voltage matter. The single +12 V rail design simplifies power distribution across modern graphics cards and CPUs.

Flat Modular Cables & Honeycomb Ventilation

Only the cables required for the build are connected, reducing internal clutter and improving airflow through the honeycomb grille. Low-profile nylon-sleeved flat cables make routing easier in tight chassis layouts. A 135 mm fan runs in a zero-RPM mode at low loads, keeping acoustics down during idle or light workloads.

Japan-Made Capacitors & 11.6 ms Hold-Up

Japanese main capacitors provide the 11.6 ms hold-up time at full load, giving the system a brief ride-through during momentary mains dips. The 80 Plus Gold rating guarantees over 90 % efficiency at 50 % load, limiting waste heat. Builds demanding sustained loads well above 850 W or requiring redundant power paths will need a higher-capacity unit.

Questions about this item

How long will the main capacitors last before they need replacing?

The Japan-made main capacitors are rated for a hold-up time of 11.6ms at full load and are designed to prevent explosion and leakage issues for long-term durability.

What is the efficiency drop-off point when the PSU runs at high load for hours?

The unit delivers over 90 percent energy efficiency at 50 percent load per its 80 Plus Gold certification; efficiency will be lower at sustained higher loads.

How loud does the 135mm fan get when the system runs all day?

A zero RPM fan mode keeps the 13.5cm fan off at low loads, while the honeycomb structure maximises airflow to limit noise and heat during extended operation.
