750W ATX power supply for gaming builds
The MSI MAG A750BN PCIE5 delivers 750 W of continuous power from a standard Intel ATX 12V design. It targets entry-level gaming systems that need a reliable unit with modern GPU support. The 80 PLUS BRONZE rating confirms efficient operation across typical loads. A single 120 mm sleeve-bearing fan handles cooling duties.
Non-modular cables with native 16-pin GPU connector
All cables are fixed, so unused leads must be routed inside the case. The unit includes one 24-pin ATX, one 8-pin EPS, two 8-pin PCIe, five SATA, two Molex and one FDD connector. A native 16-pin 12V-2x6 cable supplies up to 300 W to PCIe 5.0 graphics cards such as the RTX 4070 series. DC-to-DC circuitry keeps minor rails stable.
150 mm depth fits compact cases
At 150 mm long the supply suits smaller chassis where longer units cannot be installed. Active PFC accepts 100-240 V input at 50/60 Hz for worldwide use. Protections cover over-current, over-voltage, over-power, over-temperature and short-circuit events. The fixed cable set limits routing flexibility in very tight layouts.
