This article covers Corsair RM1000e (2025) 完全モジュラーATX電源 12V-2x6ケーブル付き ATX 3.1およびPCIe 5.1に対応 Cybenetics Gold 105°Cのコンデンサ ブラック.

Overview

The Corsair RM1000e (2025) is a fully modular ATX power supply that hits the sweet spot for modern high-end builds. Rated at 1000W and carrying Cybenetics Gold certification, it delivers reliable and efficient power. It fully supports ATX 3.1 and PCIe 5.1 standards, and comes with a native 12V-2x6 cable ready for next-generation graphics cards. A 120mm rifle-bearing fan keeps noise levels low, while 105°C-rated capacitors ensure long-term durability. This PSU is ideal for gamers, content creators, and anyone building a future-proof system.

Compatibility Guide

The Corsair RM1000e (2025) uses a standard ATX form factor and fits almost any mid-tower or full-tower case. Its fully modular design lets you connect only the cables you need, keeping the build clean and improving airflow. Connector inventory includes one 24-pin ATX, two EPS 4+4-pin, two PCIe 6+2-pin, one 12V-2x6, six SATA, and two PATA connectors. It works natively with NVIDIA GeForce RTX 50 series and AMD Radeon RX 9000 series GPUs. It doesn't depend on CPU socket or memory type, but make sure your system's total power draw doesn't exceed 1000W. This PSU is best paired with builds that demand 650W or more – 1000W gives generous headroom for single-GPU high-end setups.

Product Info

The Corsair RM1000e (2025) sits in the mid-to-high-end PSU segment. Released in 2025, it has a street price around ￥30,000 in Japan and comes with a 10-year warranty. Cybenetics Gold efficiency translates to 87-90% across typical loads. The unit measures 140mm in depth, making it relatively compact for a 1000W PSU. It is available through Corsair's official store, , and major PC hardware retailers.

Best Use Cases

First, this PSU is a natural choice for high-end gaming rigs. If you're building with an RTX 5080 or RTX 5090, the 1000W capacity and native 12V-2x6 cable provide a clean, stable power path. Second, it suits content creators who run long rendering or encoding sessions – the 105°C capacitors and high efficiency reduce heat and improve reliability under sustained loads. Third, it's great for first-time builders who want a hassle-free cable management experience. The fully modular design means you only attach what you need, drastically simplifying installation. ## Alternatives
Direct competitors include the Seasonic Focus GX-1000 and Thermaltake Toughpower GF3 1000W. The Seasonic offers similar 80 PLUS Gold efficiency and a 10-year warranty, but it does not include a 12V-2x6 cable – you'd need to buy one separately. The Thermaltake GF3 supports ATX 3.0 and includes a 12VHPWR cable, but it's the previous connector generation. The Corsair RM1000e (2025) wins on future-proofing with ATX 3.1 and the latest 12V-2x6 standard out of the box. If you need a slightly lower price, the RM750e (2025) is worth considering for mid-range builds.

Things to Consider

While the RM1000e (2025) is ATX 3.1 compliant, it still fits standard ATX cases without issue. However, its 140mm depth is shorter than many high-wattage PSUs, so be sure to check your case's PSU clearance if it's particularly compact. Cybenetics Gold is roughly equivalent to 80 PLUS Gold; if you demand Platinum or Titanium efficiency, this PSU may not satisfy you. 1000W is overkill for systems with mid-range GPUs like an RTX 5060 or RX 8600 – consider the 750W or 850W version to save money. Also, only one 12V-2x6 cable is included; if you plan to run multiple high-power GPUs, you'll need to source an additional cable separately.
