MSI MAG A500N-H

The MSI MAG A500N-H is an ATX-format power supply with a 500 W output, designed for basic and mid-range configurations featuring a single graphics card and a standard set of storage drives. The unit features a non-modular design, with all cables permanently attached, which simplifies connection but requires careful cable routing within the chassis. The MSI MAG A500N-H employs active PFC, a single +12 V rail, and a 120 mm hydraulic-bearing fan for cooling internal components under sustained load. On the +12 V rail, the unit can deliver up to 38 A, or up to 456 W, making this channel the primary power source for the processor and graphics card. Protection circuitry includes OCP, OPP, SCP, and UVP, which are essential for stable system operation in the event of overload, short circuit, or voltage sag. The MSI MAG A500N-H supports input voltage between 200–240 V at 50–60 Hz, making it suitable for standard mains in this range. The connector lineup includes 1 × ATX 24-pin, 2 × EPS 4+4-pin for CPU power, 1 × PCI-E 6+2-pin, 3 × SATA, 2 × Molex, and 1 × FDD. The chassis dimensions are 140 × 150 × 86 mm, conforming to standard ATX dimensions and ensuring compatibility with most cases. The MSI MAG A500N-H is well-suited for home PCs, office systems, or budget-conscious gaming builds without demanding multiple PCIe connectors.
