SAMA H500 Black 500W - PSU, 80 Plus White

The SAMA H500 500W 80 PLUS White ATX power supply provides stable DC power for desktop components. This ATX 2.52 unit delivers up to 500 watts of continuous output. A single +12V rail provides consistent power for modern processors and graphics cards, while the DC-to-DC converter and active power factor correction ensure stable voltage regulation under load. With an 80 PLUS White certification and 85% typical efficiency, it helps minimize heat generation within the chassis.

Thermal management is handled by a 120 mm temperature-controlled fan that adjusts speed based on internal system heat. A silent mode reduces noise during low-demand tasks. As this is a non-modular unit, all wiring is permanently attached, requiring users to manage unused cables within the case. Integrated safeguards include over-voltage, over-power, short-circuit, under-voltage, and no-load protection.

• 100,000-hour MTBF: projected lifespan for internal circuitry.
• Two 6+2-pin PCIe connectors: for graphics cards requiring supplementary power.
• Four SATA power connections: for multiple storage drives.
• 600 mm CPU power cable: length sufficient for routing behind motherboard trays.
• 550 mm main ATX cable: for standard 20+4-pin motherboard sockets.
• 0–30 °C operating temperature: safe ambient thermal range.
