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.

Questions about this item

Will the 500 W unit handle a graphics card that needs two 8-pin power connectors?

Yes, the PSU provides two 6+2-pin PCIe connectors, each able to serve an 8-pin socket, so a card requiring two such connectors is supported within the 500 W limit.

Does the non-modular cable set include enough SATA power plugs for multiple drives?

Six SATA power connectors are supplied on the fixed cables, allowing several SSDs or hard drives to be powered without extra adapters.

What protections guard against voltage spikes or short circuits?

The unit includes over-voltage, over-temperature, over-power, short-circuit, no-load and surge-inrush protection circuits.
