840 W Full Modular ATX PSU

This 840 W full modular ATX power supply delivers up to 450 W of rated output power. The fully modular cable design lets builders connect only the cables their system needs. An integrated 256 colour RGB fan provides customisable lighting that can be switched or turned off. It is suited to gaming PCs that value cable management and visual flair.

80 PLUS Gold Efficiency Quiet Fan

The unit carries 80 PLUS Gold certification and reaches up to 90 % efficiency during normal operation. A high static pressure fan runs almost inaudibly while maintaining stable temperatures. Comprehensive protections cover over current, over voltage, over power, over temperature, under voltage and short circuit events. Large capacity magnetic ring components contribute to steady output.

Replaces Lower Wattage Non Modular Units

This supply upgrades systems that rely on lower wattage non modular power supplies with fixed cable bundles. The jump is worthwhile when a build needs cleaner cable routing, higher efficiency and RGB fan lighting in one package. Builders who need more than 450 W of continuous rated power or who require additional PCIe connectors not listed should look elsewhere.

Perguntas sobre este artigo

How do I install this 140x150x85mm 840W unit and which step is often missed?

Mount the supply in the case, connect only the cables you need — 20+4 pin mainboard, 4+4 pin CPU, 6+2 pin GPU, four STAT and two IDE — then turn on the rear switch; the step people forget is leaving unused modular ports empty to preserve airflow

What maintenance will this 80 PLUS Gold 450W-rated supply need later?

No scheduled maintenance is required; dust the 256-colour fan intake periodically and check that all modular plugs stay fully seated after any hardware changes

What limit appears first during sustained heavy loads?

The continuous rated output is 450W, so that ceiling will be reached before the 840W peak figure under prolonged stress
