ASUS Prime AP-750G 750W Gold Modular ATX PSU - 80+
The ASUS Prime AP-750G 750W Gold Modular ATX PSU is a fully modular 750W power supply built for builders who want long-term reliability and efficient operation in high-performance workstations, all-round PCs, and gaming rigs. Its 80 Plus Gold certification, dual ball fan bearings, and ATX 3.1 compliance make it a capable foundation for both current and next-generation component pairings. An 8-year warranty and a two-tone black-and-white housing round out a unit designed to last and adapt to different build aesthetics.
Why this product
80 Plus Gold: up to 92% efficiency
Low-ESR capacitors earn this PSU 80 Plus Gold status, delivering up to 92% efficiency — meaning less heat generated and quieter fan operation under typical loads.
Dual ball bearings rated 80,000 hours
The fan uses dual ball bearings with a rated lifespan of 80,000 hours — twice that of sleeve bearings and longer than fluid dynamic bearings — for sustained, low-noise cooling over years of use.
ATX 3.1 ready with PCIe Gen 5.1 cable
Compliant with ATX 3.1 guidelines, it ships with a 16-pin PCIe cable compatible with PCIe Gen 5.1 graphics cards, so it is ready for current high-end GPU pairings.
Fully modular cabling
Modular connectors mean you only route the cables your build actually needs, reducing clutter and improving airflow inside the case.
Eight-year warranty
ASUS backs this unit with an 8-year warranty — longer than the 3- to 5-year coverage common at this price tier — reflecting the rated component longevity.
Comprehensive protection suite
OPP, OVP, UVP, SCP, OCP, and OTP protections guard connected components against over-power, over-voltage, under-voltage, short circuits, over-current, and over-temperature events.

- Dimensions150 × 150 × 86 mm
- Weight1.466 kg
- SKUASU-2299
- EAN4711636288354
- Fits standard ATX cases — dimensions are 150 × 150 × 86 mm, which is a standard ATX PSU footprint.
- Compatible with ATX12V motherboards via the included 24/20-pin main connector and dual 4+4-pin CPU connectors.
- Supports PCIe Gen 5.1 graphics cards through the included 16-pin cable, with three additional 8-pin PCIe connectors also provided.
- Wide AC input range of 100–240 V makes it suitable for use in most regions worldwide.
- 0dB fan-stop technology is not included — the fan runs continuously rather than stopping under light loads.
- RoHS compliant for hazardous-material regulations; verify local import requirements if ordering internationally.
Best for
- Builders prioritising longevity — dual ball bearings rated at 80,000 hours and an 8-year warranty make this a strong choice for a system expected to run for many years.
- High-performance desktop and gaming builds — 750W total output with 62A on the +12V rail covers demanding CPUs and modern discrete GPUs, including PCIe Gen 5.1 cards.
- Efficiency-conscious builders — up to 92% efficiency at Gold tier reduces wasted energy as heat, which lowers both electricity draw and thermal load inside the case.
- Cable-management-focused builds — full modularity lets you omit unused cables entirely, keeping the interior tidy without zip-tie workarounds.
- Two-tone build themes — the dual black-and-white housing panels allow orientation to suit either a predominantly white or predominantly black build aesthetic.
Trade-offs
- Builds requiring fan-stop operation — this unit does not feature 0dB technology, so the fan does not stop spinning under light or idle loads.
- SFX or compact ITX cases — at 150 × 150 × 86 mm this is a full ATX-size unit and will not physically fit smaller SFX or SFX-L bays.
- Systems needing more than five SATA connectors — the cable set includes five SATA connectors and three peripheral connectors; larger storage arrays may need adapters or a higher-connector-count unit.
With 80+ Gold certification, dual ball fan bearings, 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.
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.
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.
ATX 3.1 Compatible
ASUS Prime Gold is compliant with ATX 3.1 guidelines and bundled with a 16-pin PCIe cable that is compatible with PCIe Gen 5.1 graphics cards.
Choose Your Style
Two sides of the housing are painted white, and two sides are painted black, allowing you to orient the PSU to match your preferred build theme.
