800 W Full-Modular PSU

The TOPOWER TOP-800G delivers 800 W of continuous power through a single +12 V rail. It targets system builders who need reliable output for multi-GPU configurations and high-end components. The 80 PLUS Gold certification confirms high efficiency across typical loads. Full modular cabling lets you connect only the leads your build requires.

Build Quality and Connectivity

A 14 cm fan handles cooling inside a 150 x 160 x 86 mm chassis. Active PFC and protections against over-voltage and overload safeguard connected hardware. The unit supplies four 6+2 pin PCIe connectors, eight SATA power connectors and a 20+4 pin main connector. Full modularity keeps the cable count low and simplifies routing in standard ATX cases.

Upgrade Path and Fit

This supply replaces lower-wattage or non-modular units that cannot support SLI or CrossFire multi-GPU setups. The jump is worthwhile when your graphics cards demand four PCIe power leads or when cable clutter hinders airflow. Input voltage spans 100 to 240 V for global compatibility. Builders needing more than 800 W or a smaller form factor should look elsewhere.

Questions about this item

Does the ATX12V/EPS12V v2.3 design limit the +12 V rail to 800 W?

The single +12 V rail delivers the full 800 W so the v2.3 standard does not cap the output below the unit rating.

Will the 160 mm depth fit a case with a 150 mm PSU clearance?

No, the unit is 160 mm deep so it needs at least that much clearance from the rear panel.

How do I connect the 6+2 pin cables without forcing the extra two pins?

Slide the 6+2 block together until it clicks, then insert the combined 8 pin plug; do not push the 2 pin tail in separately.
