ASUS Prime 750W Gold PSU AP-750G - 80+ Gold, ATX 3.1
The ASUS Prime 750W Gold PSU AP-750G is a fully modular-style ATX 3.1 power supply suited to builders of high-performance workstations, all-round PCs, and gaming rigs who want efficient, long-lasting power delivery. It carries 80 PLUS Gold certification for up to 92% efficiency, and backs that with an 8-year warranty and a dual ball bearing fan rated for 80,000 hours of operation.
Why this product
80 PLUS Gold: up to 92% efficiency
The 80 PLUS Gold certification means less energy is wasted as heat, which keeps temperatures down, reduces fan noise, and lightens the load on your cooling setup.
ATX 3.1 compliant for next-gen hardware
Full ATX 3.1 compliance means tighter voltage and current regulation, making it ready for the latest CPUs and GPUs without requiring adapters or workarounds.
Dual ball bearing fan rated 80,000 hours
Dual ball bearings last twice as long as sleeve bearings and outlast fluid dynamic bearings, delivering quiet, reliable airflow across the unit's working life.
8-year warranty as standard
ASUS backs this unit with an 8-year warranty, one of the longest in its class, reflecting confidence in the components used.
Six protection circuits built in
Over-power, over-voltage, under-voltage, short-circuit, over-current, and over-temperature protection are all active, guarding your components against electrical faults.
Wide AC input range
A 100–240 V AC input range means it operates correctly on the mains voltage used anywhere in the world without a manual voltage switch.

- Does not support 0 dB fan-stop mode; the fan runs continuously under all loads.
Best for
- Gaming PC builders who want a reliable, efficient PSU with a native 16-pin GPU connector and ATX 3.1 compliance for current and upcoming graphics cards.
- Long-term builders who value an 8-year warranty and a fan rated to 80,000 hours, reducing the likelihood of needing to revisit the power supply.
- Workstation users running high-sustained loads who benefit from 80 PLUS Gold efficiency and six hardware protection circuits.
- Worldwide buyers who need a PSU that accepts 100–240 V AC without manual adjustment.
Trade-offs
- Small-form-factor builds — at 150 × 150 × 86 mm this is a full ATX unit and will not fit SFX or SFX-L cases.
- Silent-operation enthusiasts who want a zero-RPM fan-stop mode at low loads — this unit does not include 0 dB technology.
- Very high-wattage systems — the total output is 750 W, which may be insufficient for configurations combining a high-TDP CPU with a top-tier multi-GPU setup.
With 80+ Gold certification, dual ball bearing fan, and an 8-year warranty, the ASUS Prime series PSU brings efficient and durable power delivery to high-performance workstations, all-round PCs, and gaming rigs.
80 Plus Gold Certification
The ASUS Prime 750W Gold PSU features efficient, low-ESR capacitors to ensure efficient operation — affording it 80 PLUS® Gold status. This means it delivers up to 92% efficiency, resulting in less heat, reduced fan noise, and increased reliability.
Dual Ball Fan Bearings
Dual ball bearings boast a remarkable lifespan of 80,000 hours, lasting twice as long as sleeve bearings and exceeding even fluid dynamic bearings. Ensuring long-lasting, reliable cooling with minimal noise for ASUS Prime Gold series.
ATX 3.1 Compatible
The latest power specification updates have landed. ATX 3.1 ushers in tighter voltage and current regulation guidelines for next-gen hardware - and ASUS Prime 750W Gold steps ahead of the curve by being fully compliant.
