Purpose-built ATX 3.1 unit

The SAMA GP650 is a 650 W ATX 3.1 power supply built for modern gaming PCs. Its fully modular design lets builders connect only the cables required. A native 12V-2x6 connector supplies up to 450 W to PCIe 5.1 graphics cards. The single +12 V rail simplifies power distribution for high-load components.

Cybenetics Gold thermals and noise

Cybenetics Gold certification confirms over 90 % efficiency at typical load, reducing waste heat. A 120 mm fluid-dynamic-bearing fan runs under temperature-adaptive control for quiet operation. Active PFC and Full Bridge LLC plus DC-DC topology keep voltage steady. Protections include over-voltage and overload safeguards with a hold-up time above 12 ms at full load.

12V-2x6 connector for next-gen GPUs

The decisive spec is the 12V-2x6 (12+4 pin) cable rated for 450 W, enabling direct power to the latest graphics cards without adapters. Combined with two 6+2 pin PCIe cables and six SATA connectors, the unit covers current and upcoming builds. ATX 3.1 compliance guarantees compatibility with new power-excursion requirements.

Questions sur cet article

Will the 12V-2x6 connector deliver full power to a new GPU without an adapter?

The 12V-2x6 (12+4 pin) cable is rated for 450W and plugs directly into PCIe 5.1 graphics cards, so no adapter is required.

Does the fully modular design include all cables needed for a typical gaming build?

The box contains a 24-pin ATX cable, two CPU 4+4 pin cables, two 6+2 pin PCIe cables, one 12V-2x6 cable, and two SATA/Molex strings with six SATA plugs total.

Can this unit fit in a compact case with a 140 mm PSU clearance limit?

The power supply is 140 mm long, matching that exact clearance; verify your case specification allows the full length including cable bend radius.
