This article covers ASUS Prime 750W ゴールド(750ワット.

Overview

The ASUS Prime 750W Gold (AP-750G) is a fully modular ATX power supply from ASUS, delivering 80 PLUS Gold efficiency and ATX 3.0 compliance. It includes a native 16-pin PCIe Gen 5.0 cable, making it a solid choice for modern gaming and workstation builds with GeForce RTX 40-series cards or future GPUs. With a rated output of 750W, it sits in the mid-to-high range of the market, targeting users who want reliable power without stepping up to 850W or higher. The standout feature is the 120mm Axial-tech fan with dual ball bearings, which ASUS claims lasts up to twice as long as sleeve bearing designs. The fan also supports a semi-passive mode, stopping entirely under low loads (below 20%) for silent operation. Combined with low-ESR capacitors and 80 PLUS Gold certification (up to 90% efficiency at 50% load), the Prime 750W Gold offers a strong balance of durability, quietness, and energy savings. It comes with an 8-year warranty, giving buyers long-term peace of mind. Pricing in Japan typically hovers around ¥18,000–¥20,000, making it competitive with other Gold-rated 750W units from Seasonic, Corsair, and Cooler Master.

Compatibility Guide

The ASUS Prime 750W Gold follows the standard ATX form factor with a depth of approximately 140mm, so it fits in most mid-tower and full-tower cases. However, some compact Micro-ATX or Mini-ITX cases may not accommodate a 140mm-long PSU, so always check your case's power supply clearance before purchasing. Connector-wise, it includes: - 24-pin ATX main connector - Dual 4+4-pin CPU power cables (supports high-end motherboards requiring two EPS12V connectors) - One native 16-pin PCIe Gen 5.0 cable (12VHPWR) for RTX 40-series GPUs - Two 6+2-pin PCIe cables for older graphics cards - SATA and peripheral (Molex) cables This connector set covers most modern builds, including dual-CPU-power motherboard setups. The native 16-pin cable eliminates the need for dongles, reducing cable clutter and potential points of failure.

Product Info

Released in late 2023, the ASUS Prime 750W Gold is positioned as a mid-range, high-quality PSU for gamers and enthusiasts. Key specs include: - 80 PLUS Gold certification (up to 90% efficiency) - ATX 3.0 compliant (withstands up to 200% power spikes) - Fully modular cabling - 120mm Axial-tech fan with dual ball bearings - Semi-passive fan mode (fan stops below 20% load) - 8-year warranty It is widely available through Japan, major PC component retailers, and ASUS's own online store. The price-to-performance ratio is strong, especially considering the long warranty.

Best Use Cases

Mid-range gaming PC builder For a build with a Ryzen 5/7 or Core i5/i7 and an RTX 4070-class GPU, 750W is the sweet spot. The native 16-pin cable fits RTX 4070/4070 SUPER/4070 Ti SUPER without adapters, making cable management clean. Creator workstation (light to moderate) If you're using a CPU like Ryzen 9 7900X or Core i7-13700K with a single GPU such as RTX 4060 Ti or RTX 4070, the Prime 750W Gold provides ample headroom for sustained loads. The high efficiency helps keep power bills lower during long render sessions. Silence-focused PC The semi-passive fan mode means the fan stays off during web browsing, office work, and light gaming. Combined with the quiet operation of the Axial-tech fan even when spinning, this PSU is a good choice for noise-sensitive users. Who should NOT buy this If you're building a high-end system with an RTX 4090 or a dual-GPU setup, step up to an 850W or 1000W unit. Also, if you need a fully silent PSU (no fan noise at all times), consider a fanless model or a higher-end unit with a more aggressive semi-passive mode.

Things to Consider

First, 750W is becoming the minimum recommended wattage for high-end GPU configurations. While the Prime 750W Gold can handle transient spikes thanks to ATX 3.0, pairing it with an RTX 4080 SUPER or RTX 4090 may leave little headroom for overclocking or future upgrades. For such builds, an 850W+ unit is safer. Competitors in this price range include the Seasonic Focus GX-750, Corsair RM750e, and Cooler Master MWE Gold 750 V2. The ASUS Prime distinguishes itself with dual ball bearing fan longevity, native 12VHPWR cable, and an 8-year warranty. However, at times, the price may be slightly higher than these alternatives, so check current deals. Finally, confirm your case's PSU clearance. Some smaller cases (e.g., Fractal Design Terra, Cooler Master NR200) cannot fit a 140mm-long PSU. If you're building in a compact case, look for a shorter unit (120mm or less) or ensure the case specification supports ATX PSUs up to 140mm. ## FAQ
