SAMA G850 850W ATX 3.1 - PSU, 80 Plus Gold

The SAMA G850 850W Black 80+ Gold ATX 3.1 fully modular PSU provides stable power for modern desktop PCs. It follows the updated ATX 3.1 specification, allowing the unit to handle the high transient power spikes common in current graphics cards. A native 12V-2x6 connector is built in, providing direct power to compatible GPUs without the need for adapters. The unit is 80 PLUS Gold certified, achieving up to 90 percent electrical efficiency under typical loads. This efficiency reduces heat and lowers power consumption compared to base-level certified units.

The fully modular design allows system builders to use only the necessary cables, reducing clutter and improving airflow inside the case. A 140 mm fan handles active cooling, keeping internal temperatures steady during long gaming sessions or heavy workloads. Connectivity includes six SATA power connectors for storage and expansion. Three 6+2-pin PCIe headers support older graphics cards or additional expansion boards. Dual processor connections—comprising an EPS 8-pin and a 4+4-pin CPU header—ensure compatibility with motherboards requiring extra socket power.
