Smallest 850W ATX 3.1 PSU

The Super Flower Leadex VIII Platinum PRO delivers 850 W in a 125 mm deep ATX chassis, making it the shortest unit in its class. Full modular ribbon cables keep builds tidy while a 120 mm fluid-dynamic-bearing fan runs quietly. Cybenetics Platinum certification confirms high efficiency across the load range. It supports ATX 3.1 and PCIe 5.1 with a native 12V-2x6 connector.

Compact-case builders and silent rigs

This unit suits small-form-factor cases that cannot accept standard-length power supplies and users who value low noise under load. Builders needing more than 850 W or requiring multiple 12V-2x6 cables for multi-GPU setups should look at higher-wattage or larger models. Systems restricted to ATX 3.0-only motherboards will not gain the newer standard’s benefits.

125 mm depth decides fit

The 125 mm length is the single specification that determines whether this PSU fits your case. Measure the available clearance from the motherboard tray to the side panel or drive cage before ordering. If the space is shorter, this unit cannot be installed regardless of its other features.

Perguntas sobre este artigo

Will the 125 mm length fit my ATX case?

At 125 mm long this is the smallest ATX 850 W Platinum unit available, so it fits any standard ATX chassis that accepts a 125 mm deep power supply.

How do I connect the native 12V-2x6 cable for a PCIe 5.1 graphics card?

Plug the supplied 12V-2x6 cable directly into the PSU’s dedicated port and into the GPU — the common error is using an adapter instead of the native cable.

Does the 120 mm fluid-dynamic-bearing fan need periodic cleaning?

Yes, dust the 120 mm fan intake every few months to keep airflow optimal; the fluid dynamic bearing is sealed and requires no lubrication.
