850 W ATX 3.1 fully modular PSU

The SAMA GP850-Black is an 850 W ATX 3.1 power supply built for gaming PCs that demand stable delivery to modern graphics cards. Its fully modular design lets builders connect only the cables required for their specific hardware configuration.

Cybenetics Gold efficiency with 120 mm FDB fan

Cybenetics Gold certification confirms over 90 percent efficiency at typical load, reducing waste heat inside the case. A 120 mm fluid dynamic bearing fan provides quiet cooling while the single +12 V rail simplifies power distribution across all components.

PCIe 5.1 ready 12V-2x6 connector for 450 W GPU power

The native 12V-2x6 (12+4) connector supplies up to 450 W directly to compatible next-generation graphics cards without adapters. This single specification determines whether the unit matches the power requirements of the target GPU.
