This article covers CORSAIR 80PLUS GOLD認証取得 750W高耐久電源ユニット.

Overview

Corsair brings a reliable 80PLUS Gold 750W power supply to the market, designed for gamers and workstation builders who need a clean, quiet, and efficient PSU. The fully modular cable system eliminates unused cables, making cable management a breeze. With a compact depth of 160mm, it fits into most ATX mid-tower cases without issue. This unit carries the 80PLUS Gold certification, achieving over 87% efficiency at typical loads. The 135mm fluid dynamic bearing fan operates quietly even under moderate load, and the semi-fanless mode keeps it silent during low-power tasks. The 750W capacity is a sweet spot for single high-end GPU builds, providing enough headroom for overclocking. Sold as an official Japanese distributor product, it comes with a 1-year warranty. Positioned as an entry-high PSU, it offers a solid balance of performance, features, and price for the demanding mainstream user.

Compatibility Guide

The PSU complies with ATX12V v2.4 and works with any standard ATX motherboard. Before purchasing, measure your case's power supply clearance: the unit is 160mm deep, so ensure at least 170mm of available space. Supports ATX, Micro-ATX, Mini-ITX motherboards (with ATX power connector) Connectors: 24-pin main, 1x CPU 4+4-pin, 2x PCIe 6+2-pin, 6x SATA, 4x peripheral 4-pin Ideal for single GPU systems up to RTX 4070 / RX 7800 XT; dual GPU or RTX 4090 requires 850W+ Place fan facing downward (intake) for optimal cooling and natural heat exhaust

Product Info

Released around 2018, this Corsair PSU carries a retail price of approximately ¥21,500 in Japan. It features 80PLUS Gold certification, fully modular cables, and a 135mm fan. In the market, it sits in the “entry-high” tier — not the absolute best efficiency (Platinum/Titanium) but a very popular choice for reliable daily use. Warranty is 1 year through the Japanese distributor, which is notably shorter than the global 10-year warranty of the RMx series.

Best Use Cases

Quiet PC builds: The 135mm fan with semi-fanless mode keeps noise to a minimum, ideal for home offices or HTPCs. The modular cables reduce clutter, improving airflow and making the build look cleaner. Mid-range gaming rigs: Pair this 750W unit with an RTX 4070 or RX 7800 XT and a Core i5/Ryzen 5 for a balanced system. You’ll have enough headroom for stable gaming at 1440p or even light 4K. Secondary PC or NAS: The Gold efficiency reduces electricity waste, and the stable output is perfect for 24/7 operation. The fully modular design also helps in small form-factor cases (if compatible). Not for: Dual GPU setups, extreme overclocking with top-tier CPUs (Core i9/Ryzen 9) and RTX 4090. Those scenarios require 850W-1000W units.

Things to Consider

The biggest caveat is the warranty: only 1 year in Japan, whereas Corsair’s global RMx series typically offers 10 years. This significantly affects long-term value. Competitors like Seasonic Focus Gold offer 10-year warranties at similar price points. Physical clearance is another factor: while 160mm fits most mid-tower cases, some compact Micro-ATX or Mini-ITX cases may be too tight. Double-check your case specs before ordering. Also note that the unit lacks a native 12VHPWR connector for RTX 40-series GPUs. You’ll need to use the included adapter or a separate 12VHPWR cable (compatible with Corsair Type 4). ## FAQ
Q: Can this PSU power an RTX 4070? A: Yes, 750W is sufficient for an RTX 4070 (200W TDP) and a mid-range CPU. Use the included PCIe adapter or a Corsair 12VHPWR cable (Type 4). Q: Which motherboards are compatible? A: Any ATX motherboard works. For Mini-ITX boards, ensure your case has enough depth for a 160mm PSU. Q: Why is the warranty only 1 year? A: This product is sold through the Japanese distributor with a 1-year guarantee. Corsair’s official global warranty is 10 years for the RMx series, but the Japanese market version may differ. Check with the seller for details.
