This article covers ALIMENTATIONS CORSAIR 601-850ワット RM750 750W CP-9020195-EU.

Overview

The CORSAIR RM750 (CP-9020195-EU) is a 750W ATX power supply with 80 PLUS Gold certification, delivering reliable and efficient power for mid-range to high-end PCs. It features a single +12V rail rated at 62.5A, ensuring clean and stable power delivery to CPU and GPU. A 120mm rifle bearing fan supports Zero RPM mode, keeping the unit silent under light to moderate loads.
This semi-modular design means the main 24-pin and EPS12V cables are fixed, while peripheral cables (PCIe, SATA, Molex) are detachable. This simplifies cable management without the cost premium of fully modular units. Backed by a 5-year warranty and CORSAIR's reputation, the RM750 is a solid choice for builders who want quality without overspending.

Compatibility Guide

  • Form factor: Standard ATX (150 x 86 x 160 mm). Fits most ATX cases; double-check PSU clearance (depth) in compact mid-tower cases.
  • Motherboard connector: 24-pin fixed cable, EPS12V 4+4-pin (two cables for high-end boards).
  • GPU connectors: Four PCIe 6+2-pin cables — supports one high-end GPU (e.g., RTX 4070 / RX 7800 XT) or dual mid-range GPUs.
  • Storage: Nine SATA power connectors and six Molex connectors; ample for multiple SSDs, HDDs, and fan hubs.
  • Compliance: ATX12V v2.4. Works with all modern Intel and AMD platforms.
  • Not compatible with 12VHPWR connectors natively; use included adapters for RTX 40-series cards.

Product Info

  • Release: 2019 (RM series refresh)
  • Real-world price: 12,000–15,000 JPY (Japanese online retailers at time of writing ~13,000 JPY)
  • Warranty: 5 years
  • Efficiency: 80 PLUS Gold (up to 90% at typical load)
  • Fan: 120mm rifle bearing with Zero RPM mode
  • Rail design: Single +12V rail (62.5A)
  • Market position: Mid-high tier. Offers Gold efficiency and semi-modular cabling at a competitive price, sitting between budget Bronze units and premium fully modular Platinum models.

Best Use Cases

① 1080p / 1440p Gaming Build
Perfect for a single GPU setup like RTX 4070 or RX 7800 XT paired with a mid-range CPU (Ryzen 5 / Core i5). 750W leaves headroom for overclocking and additional drives. Zero RPM mode keeps the system quiet during light gaming or desktop use.
Not for: Enthusiasts planning dual high-end GPUs or RTX 4090 builds — you'll need 1000W+.
② Quiet System for Creative Work
Video editing, 3D rendering, or music production benefits from the RM750's low noise profile. Under 40% load the fan stays off, and even under full load it remains subdued (sub-25 dBA).
Not for: Absolute silence seekers may prefer a fanless PSU or a larger unit that runs cooler.
③ Budget-Conscious First-Time Builder
Semi-modular cabling is easier to manage than non-modular, and the price is hard to beat for Gold-rated quality. The 5-year warranty provides peace of mind for newcomers.
Not for: Those who want fully modular cables for the cleanest look — step up to the RMx series.

Things to Consider

The RM750's primary compromise is its semi-modular design: the 24-pin and EPS cables are permanently attached. While this isn't a problem for most builds, tight ITX cases or clean-wire enthusiasts may prefer a fully modular unit.
It lacks ATX 3.0 / PCIe 5.0 support. If you're building with an RTX 4070 Ti Super or higher (which use 12VHPWR), you'll need to use the included 8-pin adapters, adding cable clutter. For future-proofing, consider a native ATX 3.0 PSU.
Competition includes the Seasonic Focus GX-750 (full modular, same efficiency) and the Be Quiet! Pure Power 12 M (ATX 3.0). The RM750 often wins on price but loses on modularity.

FAQ

Q: Can the RM750 power an RTX 4070 Ti Super?
A: Yes, but you'll need to use both PCIe 6+2-pin cables with the included 12VHPWR adapter. The 750W capacity is sufficient for this GPU + a mid-range CPU. For RTX 4080 Super or higher, 850W+ is recommended.
Q: Is the RM750 compatible with sleep states and modern CPU power management?
A: Yes, it supports C6/C7 sleep states and is compatible with Intel's latest S-states and AMD's Cool'n'Quiet. It operates efficiently across the entire load range.
Q: How does it compare to the CORSAIR RM750x?
A: The RM750x is fully modular, uses Japanese capacitors, and has a 10-year warranty. The RM750 uses Taiwanese capacitors and a 5-year warranty, but is significantly cheaper. Choose RM750x for long-term investment or full modularity; RM750 for best value.
