Stable Continuous Power

The unit provides up to 650W of continuous output. A power supply should be selected according to the complete system specification, including the processor, graphics card, storage devices, cooling hardware and expected upgrade path.

Efficiency and Reduced Heat

The 80 PLUS Bronze certification describes the PSU's energy-conversion efficiency under defined test conditions. Higher efficiency can reduce the amount of electrical energy lost as heat, helping the cooling system operate more effectively.

Modern Graphics-Card Power

1 x native 300W 12V-2x6 connector plus conventional PCIe support. Where a native 12V-2x6 or 16-pin cable is supplied, it should be inserted fully at both ends and routed without a tight bend immediately beside the connector.

Cable Management

The Fixed standard cabling design determines how the cables are connected. The attached cable set provides the essential connections without requiring separate modular cables.

Cooling and Noise

Cooling is provided by a 120mm hydraulic bearing fan. Fan speed and acoustic output vary with temperature, input voltage and power load. Adequate ventilation around the PSU intake and exhaust remains important.

Electrical Design and Reliability

DC-to-DC power design with active PFC. Components are selected for dependable everyday operation. Over-voltage, under-voltage, over-current, over-power, over-temperature and short-circuit protection help protect the PSU and connected components from abnormal electrical conditions.

System Compatibility

The PSU uses the ATX format and measures 140 x 150 x 86mm. Before ordering, confirm the PC case supports the unit's length and cable-exit position. The motherboard, CPU and graphics-card connector requirements should also be checked against the supplied cable set.
