SAMA G-Series 650 W ATX 3.1 PSU

This fully modular power supply delivers 650 W of continuous power for high-performance gaming PCs and content-creation workstations. Its ATX 3.1 design includes a native 12V-2x6 connector so modern graphics cards can draw up to 600 W from a single cable.

Cybenetics Gold efficiency with 140 mm FDB fan

The unit meets Cybenetics Gold coverage, keeping efficiency above 90 % while the 140 mm fluid-dynamic-bearing fan runs in ECO mode below 40 % load for near-silent operation. Active PFC and a single +12 V rail provide stable output across the 100-240 V input range.

Compact 150 mm depth fits small-form-factor cases

At 150 mm long the chassis installs in most compact enclosures without blocking drive bays or radiator space. All cables are detachable, letting builders connect only the 24-pin, one 6+2-pin PCIe and two SATA leads required for their specific build.
