MSI MAG A500DN II 500W power supply

Power for mainstream builds

The MSI MAG A500DN II is a 500 W ATX12V unit built for systems that run a single graphics card and standard storage. It suits gamers and office users who need reliable delivery without the cost of higher-wattage models. The 80 PLUS Standard rating confirms up to 80 percent efficiency under typical loads. A 120 mm fan handles cooling across the operating range.

Fixed cable layout and rail design

The non-modular design means every lead stays in the case, so builders must route the full set of 24-pin ATX, 8-pin EPS, two 6+2-pin PCIe, six SATA and two 4-pin peripheral connectors. A 12 V single-rail topology supplies 21 A on the primary rail, simplifying power distribution for the GPU and CPU. Active PFC accepts 100-240 V input at 50/60 Hz without a voltage switch.

Protections and black flat cables

Six protection circuits — OVP, OTP, OPP, SCP, NLP and SIP — shut the unit down if voltage, temperature or current exceed safe limits. The supplied cables use a black flat profile that lies flush against panels and eases bundling behind the motherboard tray. No software or extra accessories are included in the package.
