SAMA B650 Black 650W ATX 3.1 - PSU, 80 Plus Bronze

The SAMA B650 Black 650W ATX 3.1 Power Supply is a desktop power unit that converts AC wall power into stable DC voltages for PC components. It provides a continuous output of 650 W, suitable for standard desktop hardware. The unit complies with the ATX 3.1 specification, meeting the structural and transient response requirements of modern motherboards. It includes native PCIe 5.1 compatibility and the 12V-2x6 standard to support the power requirements of modern graphics cards. The unit holds an 80 PLUS Bronze certification, confirming an 85% efficiency rating under typical loads, and utilizes an active power factor correction (APFC) circuit to optimize AC power draw.

The power supply features a non-modular design, meaning all cables are permanently attached to the chassis. A 120 mm fan at the base handles thermal dissipation. The unit is rated for a mean time between failures (MTBF) of 100,000 hours and functions in ambient temperatures between 0 and 40 °C. Connections include a 24-pin motherboard plug and an 8-pin EPS connector, which uses a 4+4-pin layout to suit different board designs. The unit is certified to CE, FCC, and UKCA standards.

• Safety: Includes UVP, OVP, OCP, OPP, OTP, SCP, NLP, NLO, and SIP protection to prevent damage from voltage irregularities.
• SATA capacity: Includes six SATA power connectors for storage drives and accessories.
• GPU support: Features two 6+2-pin PCIe connections for compatibility with previous-generation graphics cards.
• CPU cable length: The 700 mm EPS CPU power cable allows for routing behind motherboard trays.
• Motherboard cable length: The 550 mm primary ATX power cable is designed for standard header placements.
• Dimensions: Measures 150 mm in width, 86 mm in height, and 140 mm in depth to ensure sufficient clearance within standard desktop enclosures.
