Power supply GENESIS Nihon 750W 750NM 20+4 pin ATX ATX White

GENESIS Nihon 750NM is a 750 W ATX power supply aimed at mid-range to more serious gaming and workstation configurations, including modern GPUs under the new standards. You get a classic ATX format with a length of only 140 mm, which facilitates installation even in more compact cases. The power supply comes with active PFC, 88% efficiency and 80+ Bronze certification, so it is not a full budget option but rather a slightly more optimized choice for long-term work. The black design is clean, and the non-modular cables are easier to manage thanks to the included accessories.

What you get

This PSU follows the new ATX 12V v3.1 standard, which means official support for modern graphics cards and their power spikes – up to 200% power excursions for GPU. The kit includes a 12V-2x6 PCIe 5.1 cable up to 600 W, so you are ready for powerful cards without relying on adapters. The fan is 120 mm FDB (fluid dynamic bearing), which usually means quieter and more durable operation compared to cheap sleeve-bearing solutions, although here there is no semi-passive mode and the fan runs constantly. Inside there is a Japanese main capacitor 105 °C, which is important for stability under high load and higher temperatures. Add to that a wide range of protections plus Cybenetics ETA Silver and LAMBDA Standard++ certifications, and you have a PSU that is designed not just to "power on" but to survive.

• Power 750 W – sufficient for serious gaming builds with a modern mid/high-end GPU and a powerful CPU, without entering extreme zones.
• ATX 12V v3.1 + ATX 3.0/3.1 – PCIe Gen 5.0/5.1 support – the power supply is prepared for the new generation of graphics cards and their short-term peaks.
• 12V-2x6 PCIe 5.1 cable up to 600 W – direct connection to modern GPUs without the need for adapters and with sufficient power headroom.
• Efficiency 88% and 80+ Bronze – less heat and losses compared to the most budget PSUs, suitable for 24/7 load.
• 120 mm FDB fan – better cooling-to-noise ratio and longer bearing life, as the fan runs constantly for stable temperatures.
• Japanese main capacitor 105 °C – more reliable operation at high temperature and longer power supply life.
• Wide protection set OCP/OPP/OTP/OVP/SCP/SIP/UVP/NLO – protection for your system against short circuits, overload, overvoltages, drops and other anomalies in the power supply.
• Non-modular "oplot" round cables with combs and velcro – although not modular, cable management is easier and the build looks more organized.
• Input 100–240 V AC, 50–60 Hz, 9–4.5 A – universal compatibility with the electrical grid, suitable even with less stable power supply.

Who is it suitable for

GENESIS Nihon 750NM is a good choice if you are building a gaming or workstation machine with a modern graphics card, and you want a PSU that follows the current ATX 3.0/3.1 and PCIe 5.x standards, without paying for premium Gold/Platinum class. Suitable for 1080p and 1440p gaming builds and systems that are often under load. If you are looking for a fully modular power supply, semi-passive mode, or a higher efficiency class, you will need to look at the upper segment.

The most sensible here is the combination of ATX 12V v3.1 support for modern GPUs, 12V-2x6 cable up to 600 W, Japanese capacitor and real Cybenetics certifications in a balanced 750 W package. This makes Nihon 750NM a stable foundation for a serious but reasonably sized build.
