650 W ATX 3.1 Fully Modular PSU

The SAMA GT650-Black delivers 650 W of continuous power through an ATX 3.1 compliant design with full modular cabling. Dual Gold certification from 80 PLUS and Cybenetics confirms high efficiency and low acoustic output. Japanese capacitors provide stable voltage regulation across the single 12 V rail.

Installation uses native 12V-2x6 GPU cable

Only the cables required for the build need to be connected, reducing clutter inside the case. The 120 mm ECO fan features auto speed control and FDB bearing for quiet operation. A hold-up time greater than 11 ms and full protection suite guard against voltage irregularities.

Suits builds with RTX 4090 class graphics

The native 12V-2x6 connector removes the need for adapters when powering modern GPUs. Input range of 100-240 V at 50-60 Hz supports global mains without switching. Systems requiring more than 650 W or additional PCIe connectors should consider higher-capacity units.
