ATX 3.0 power supply for modern builds

The ASUS AP-750G delivers 750 W through a fully modular ATX12V design that meets ATX 3.0 guidelines. A single 135 mm fan with dual ball bearings and axial-tech blades provides cooling. 80 PLUS Gold certification reflects low-ESR capacitors and premium components. The unit measures 150 x 150 x 86 mm and weighs 1.466 kg.

Suitable for PCIe Gen 5 graphics cards

One native 16-pin PCIe connector plus three 8-pin PCIe connectors support current and next-generation GPUs. Two CPU 4+4-pin cables handle high-end desktop processors. Five SATA and three peripheral connectors cover storage and accessories. Builders needing more than three 8-pin PCIe cables or a shorter depth than 150 mm should verify case clearance first.

Check case depth and cable routing before ordering

The 150 mm length must fit your chassis with room for the 24-pin, CPU and PCIe cables, which range from 610 mm to 675 mm. Confirm your motherboard uses a 24-pin main connector and 8-pin CPU power. Ensure the 100-240 V input matches your mains supply. The package includes all listed cables and a power cord.

Questions about this item

Do I need a case that fits a 150 mm deep ATX power supply?

The unit is 150 mm deep and 86 mm tall, so the case must accept a standard ATX PSU of at least that length and height.

Can I keep my older motherboard with a 24-pin ATX and two 4+4-pin CPU sockets?

The PSU includes one 24/20-pin motherboard cable and two 4+4-pin CPU cables, so it connects directly to those sockets.

How do I confirm the PSU is delivering power to a PCIe Gen 5 graphics card after installation?

The bundled 16-pin PCIe Gen 5 cable plugs into the PSU’s 16-pin port and the card’s 16-pin connector; the system will post and the GPU will appear in device manager when power is correct.
