800W ATX power supply for modern PCs

This 800W ATX unit delivers stable power for mid-range and high-end desktop builds. It carries 80 PLUS Gold certification for high efficiency and lower running temperatures. Modern Standby compatibility enables extremely fast wake-from-sleep times. The platform suits gamers, creators and professionals who need reliable output.

Upgrading from lower-efficiency

Replacing an older bronze-rated or non-Modern Standby supply cuts idle power draw and improves sleep-state responsiveness. The resonant LLC topology with DC-to-DC conversion reduces coil whine and provides cleaner voltage regulation. The jump is worthwhile when building a new system or when an existing unit lacks the efficiency or sleep-state support required by current platforms.

800W headroom for single-GPU configurations

An 800W capacity comfortably handles a modern CPU paired with a single high-performance graphics card and typical peripherals. Zero RPM fan mode keeps the unit silent at low and medium loads. The unit runs out of headroom for multi-GPU setups or extreme overclocking scenarios that demand sustained output beyond the rated wattage.

Questions about this item

Does the 800W ATX unit fit a standard ATX case cutout?

Yes, it uses the standard ATX form factor so it mounts in any case with an ATX power-supply opening.

Which cables must be connected during installation to avoid a no-post issue?

Attach the 24-pin ATX motherboard connector and the 8-pin EPS CPU connector; missing either will prevent the system from starting.

How often should the fan intake be cleaned to keep the Zero RPM mode effective?

Remove dust from the fan grille every six to twelve months with compressed air so the fan can stay off at low loads.
