This article covers CORSAIR RM1000e (2025) 完全モジュラー低ノイズATX電源 12V-2x6ケーブル付き.

Overview

The CORSAIR RM1000e (2025) is a fully modular 1000W power supply that embraces the latest ATX 3.1 and PCIe 5.1 standards, now available in a clean white finish. It delivers reliable power for high-end gaming rigs and creative workstations, with Cybenetics Gold efficiency that keeps noise and heat in check. The native 12V-2x6 connector (rated for 600W) makes it a drop-in choice for next-gen GPUs like the GeForce RTX 5090 without any adapters. Positioned as a mid-high-tier PSU, it strikes a strong balance between feature set and price.

Compatibility Guide

The RM1000e uses the standard ATX form factor with a depth of only 140mm, fitting most mid-tower and many compact cases. Its fully modular cabling means you only connect the cables you need, keeping airflow clean. Connector set: 24-pin ATX, two 4+4-pin EPS12V (CPU), one PCIe 6+2-pin, one 12V-2x6 (12+4-pin), plus a 12V-2x6-to-dual-8-pin PCIe cable. Six SATA and two PATA connectors cover storage. GPU compatibility: Native 12V-2x6 works directly with RTX 40/50-series cards. Older GPUs can use the 6+2-pin PCIe cables or the adapter. Motherboard fit: The EPS12V cables reach easily in most modern cases. Dual EPS connectors are provided for high-end boards. Important: Always check your case’s PSU clearance – 140mm depth is compact but some ultra-small ITX cases may require SFX units.

Product Info

Released in early 2025, the RM1000e (2025) retails around ¥60,000–¥61,000 in Japan (as of August 2026). It is Cybenetics Gold certified (equivalent to 80 PLUS Gold) and comes with a 7-year warranty. CORSAIR’s RMe line focuses on delivering essential modern features – ATX 3.1, full modularity, and quality components – without the premium of the flagship RMx or HXi series. Rated wattage: 1000W Efficiency: Cybenetics Gold ATX version: ATX 3.1 / PCIe 5.1 Fan: 120mm rifle bearing, semi-passive (stops under ~40% load) Capacitors: 105°C rated, Japanese/high-quality Protection: OPP, OVP, UVP, SCP, OTP * Warranty: 7 years (manufacturer) Market positioning: mid-high. It offers top-tier compatibility with future GPUs while keeping cost reasonable, suitable for builders who want modern features without the Platinum premium.

Best Use Cases

High-end gaming PC builder: Perfect pairing with RTX 5080/5090 and Intel Core i9 or Ryzen 9. The 1000W headroom ensures stability during transient spikes, and the white cables match light-themed builds. Creative workstation: For sustained CPU+GPU loads in rendering, AI training, or video editing, the 105°C capacitors and high efficiency handle long sessions reliably. Silence-focused user: The semi-passive fan mode keeps the PSU silent under typical desktop or light gaming loads. Even at full load, noise is modest. Compact ATX builds: At 140mm depth, this PSU fits many cases that normally require shorter units. Just double-check the PSU compartment dimensions.

Things to Consider

Overkill for mid-range: If you’re building with a RTX 4060-class GPU and a Core i5, a 650–750W PSU would suffice. The RM1000e makes sense if you plan a future GPU upgrade. Competitors: Seasonic Focus GX-1000 and be quiet! Straight Power 12 1000W offer similar specs. The RM1000e’s advantage is native 12V-2x6 and compact size. For Platinum efficiency, look at CORSAIR RMx or HX series. White cable care: White sleeved cables look great but may show dust or stains more easily. Consider your case’s interior color and lighting. ATX 3.1 nuance: While fully backward compatible, the native 12V-2x6 benefit is most relevant for RTX 40/50-series and future GPUs. Older builds work fine with included adapters. ## FAQ
Q: Can this PSU power an RTX 5090? A: Yes. It includes a native 12V-2x6 connector rated for 600W, which is sufficient for the RTX 5090’s peak power draw. The ATX 3.1 certification guarantees it can handle transient spikes up to 2x rated current for short durations. Q: Does the fan always spin? A: No. The RM1000e uses a semi-passive fan curve – the fan stays off until the load exceeds roughly 40% of rated capacity. Under typical gaming or creative loads, you may often find it running silently or stopped. Q: How does it compare to the CORSAIR RMx 1000? A: Both are Gold-rated fully modular units. The RM1000e (2025) adds native 12V-2x6 and ATX 3.1, while the RMx typically uses higher-grade capacitors and a slightly different fan. The RM1000e is generally more affordable and suits users who want the latest connector standard.
