440W ATX Power Supply

This 440 watt ATX power supply is built for desktop PCs that need efficient, reliable power delivery. It carries 80 PLUS Gold certification and uses a resonant LLC topology with DC-to-DC conversion for clean output. Modern Standby compatibility ensures fast wake times and improved low-load efficiency. The unit is new and ready for system integration.

Ideal for efficient mainstream builds.

This unit suits builders assembling mainstream desktops or office machines where 80 PLUS Gold efficiency and quiet operation matter. The Zero RPM fan mode keeps noise low at typical loads. It is not suited for systems with multiple high-end graphics cards or heavy overclocking that demand higher wattage headroom. Buyers needing more power for multi-GPU arrays should look elsewhere.

440 watts continuous capacity

The 440 watt rating provides comfortable headroom for single-GPU gaming rigs, productivity workstations and general-purpose desktops. Gold-rated efficiency reduces waste heat and electricity draw across the load range. At very high sustained loads approaching the maximum rating the fan will spin up and headroom diminishes. The resonant LLC design maintains stable voltages within this envelope.

Questions about this item

Does this 440W unit include the 24-pin ATX cable and the 8-pin EPS cable my motherboard needs?

Yes, as an ATX-type supply it ships with the standard 24-pin motherboard connector and the 4+4-pin CPU power connector required by current boards.

Will the Zero RPM Fan Mode and Modern Standby support work with a motherboard that is a few years old?

Zero RPM operates from the unit's own thermal curve so it functions on any ATX board; Modern Standby requires a compatible motherboard and OS, but the supply remains fully usable without it.

How can I confirm the 80 PLUS Gold efficiency is active after installation?

Check the fan stays off at idle and use a software monitor or wall meter to verify low-load draw matches Gold-class expectations.
