This article covers Corsair RM750e 750W PC電源ユニット CP-9020248-JP PS1213 80PLUS GOLD認証 フルモジュラーATX.

Overview

The Corsair RM750e is a 750W fully modular ATX power supply with 80PLUS GOLD certification, model number CP-9020248-JP. It features a compact 140mm depth chassis and a 120mm rifle-bearing fan that supports Zero RPM mode, keeping the fan completely still under low loads for silent operation. This PSU targets mid-range to upper-mid-range gaming PCs and creator workstations. With two EPS12V 8-pin CPU cables included, it comfortably handles Ryzen 7 / Core i7 processors paired with mid-tier GPUs like the RTX 4060 or RX 7600. The fully modular design lets you connect only the cables you need, improving airflow and making cable management much cleaner. Corsair backs the RM750e with a 7-year warranty, giving long-term peace of mind. It sits in a competitive price bracket around $90–$110 USD, offering a strong balance of efficiency, modularity, and reliability.

Compatibility Guide

The RM750e follows the standard ATX form factor and fits most mid-tower and many compact ATX cases thanks to its 140mm depth. It is compatible with all modern platforms including Intel LGA1700/1200/115x and AMD AM5/AM4. Connectors: 1x ATX 24-pin, 2x EPS 8-pin (CPU), 4x PCIe 6+2-pin (GPU), 9x SATA, 6x peripheral 4-pin. Enough for multi-GPU setups or multiple storage drives. Memory & Storage: No restrictions — works with DDR4/DDR5, SATA SSDs, NVMe SSDs, and HDDs. * Important: The RM750e does NOT include a native 12VHPWR (12V-2×6) connector. For GeForce RTX 40-series and newer high-end GPUs, you will need to use the included PCIe 6+2-pin cables with an adapter, or purchase a separate Corsair Type 4 12VHPWR cable.

Best Use Cases

Mid-range gaming builds: Pair with a Ryzen 5 / Core i5 CPU and an RTX 4060 / RX 7600 GPU. The 750W capacity provides ample headroom, and the fully modular design makes cable routing easy even in compact cases. Silence-focused users: Zero RPM mode keeps the fan off under light loads (roughly below 40% load). For desktop work, web browsing, or media playback, the PSU operates completely silently. * Future-proof upgraders: 750W gives you room to move up one GPU tier or add more storage without swapping the PSU. The 7-year warranty supports long-term use. ## Alternatives
In the same 750W / 80PLUS GOLD / fully modular category, the Seasonic Focus GX-750 and EVGA SuperNOVA 750 G7 are direct competitors. Seasonic Focus GX-750: Comes with a native 12VHPWR connector, making it a better choice for RTX 40-series GPUs without adapters. However, it is slightly longer (160mm vs 140mm), which may be a concern in smaller cases. EVGA SuperNOVA 750 G7: Offers a 10-year warranty and similar compact dimensions (150mm). Availability and pricing in Japan can be less consistent compared to the RM750e. Overall, the RM750e wins on price-to-performance ratio, compact size, and quiet operation, especially for users who don't need native 12VHPWR.

Things to Consider

No native 12VHPWR: If you plan to use an RTX 4070 Ti SUPER or higher, you will need an adapter or a separate Corsair Type 4 12VHPWR cable. This adds a small extra cost and cable management complexity. Capacity overkill for low-end builds: For office PCs or entry-level gaming rigs with no discrete GPU, 750W is overkill. A 550W–650W unit would be more cost-effective. Cable stiffness: Corsair's Type 4 cables are on the stiffer side, especially the 24-pin ATX cable. Users who prioritize ultra-clean builds may want to invest in custom sleeved cables. Warranty registration: The 7-year warranty is manufacturer-backed, but you may need to register the product on Corsair's website after purchase. Always buy from an authorized retailer to ensure warranty validity.
