SAMA HAT-650yzB1G 650 W power supply

ATX 3.1 650 W unit

This 650 W power supply follows the ATX 3.1 specification and targets builders assembling a single-GPU desktop. Fully modular cabling keeps the interior tidy, while 80 PLUS Gold certification confirms high efficiency across typical loads. A 140 mm fluid-dynamic-bearing fan handles cooling with low noise. The compact 150 mm depth fits most mid-tower cases.

Single +12 V rail with 12V-2x6

The single +12 V rail delivers the full 650 W to modern graphics cards through a native 12V-2x6 connector rated for 600 W. One 6+2-pin PCIe cable is also included for secondary power needs. Two SATA power strings support multiple drives. Hold-up time exceeds 12 ms at full load, giving the system a brief ride-through during power dips.

100 % Japanese capacitors and protection suite

All electrolytic capacitors are Japanese-sourced, improving long-term voltage stability and lifespan. The protection suite covers over-voltage, over-current, over-power, short-circuit, under-voltage, surge and no-load conditions. A five-year manufacturer warranty backs the design. No software utilities or RGB controllers are bundled.
