This article covers CORSAIR RM750x シフトフルモジュラーATX電源.

Overview

The CORSAIR RM750x SHIFT is a fully modular ATX power supply that redefines cable management with its innovative side-mounted connector interface. Rated at 750W with 80 PLUS Gold certification, it delivers high efficiency (up to 92% at 230V) while complying with the latest ATX 3.0 and PCIe 5.0 standards. This makes it a future-proof choice for mid-range to high-end gaming PCs.
What sets the RM750x SHIFT apart is the placement of modular connectors on the side of the PSU rather than the traditional rear panel. This design allows much easier access when plugging and unplugging cables, especially in cases with limited clearance behind the motherboard tray. The 140mm fluid dynamic bearing fan features a zero-RPM mode, keeping the unit silent under light loads. Inside, 105°C-rated Japanese electrolytic capacitors ensure long-term reliability.
Positioned in the mid-high tier of the PSU market, the RM750x SHIFT offers a compelling mix of advanced features (ATX 3.0, side connectors, fully modular) at a competitive price point. It is particularly well-suited for builders who prioritize clean cable routing and ease of installation.

Compatibility Guide

The RM750x SHIFT uses the standard ATX form factor, so it fits most ATX cases. However, because the modular connectors are on the side, you need adequate clearance between the PSU and the case side panel or bottom compartment. Cases with a PSU shroud that leaves little room on the sides may cause interference. Always check your case specifications before purchasing.
It includes a native 12VHPWR connector (12+4 pin) for direct connection to NVIDIA GeForce RTX 40-series and future GPUs, eliminating the need for adapters. Multiple PCIe 6+2-pin connectors are also provided for older graphics cards. The unit supports ATX 3.0 transient power spikes, ensuring stable operation with modern high-end components.
All cables use CORSAIR Type 5 Gen 1 micro-fit connectors. The cable lengths are standard for mid-tower cases: the main ATX cable is 610mm, CPU EPS cables are 675mm, and PCIe cables are 675mm. This should be sufficient for most builds, but extra-long GPU cables may be needed for some full-tower cases.

Product Info

The CORSAIR RM750x SHIFT was released in 2023. It carries an 80 PLUS Gold efficiency rating and comes with a 10-year warranty, reflecting Corsair's confidence in its longevity. The unit is available through major online retailers like specialty PC hardware stores.
Market positioning: mid-high tier. It competes with other 750W Gold-rated fully modular PSUs but stands out due to its side connector design and ATX 3.0 compliance. For users who value cable management convenience, it offers a unique advantage over traditional designs.

Best Use Cases

  • PC builders who want the easiest cable management experience
    The side-mounted connectors make it much easier to plug and unplug cables, especially in tight spaces. This is ideal for first-time builders or anyone who frequently swaps components. However, if you prefer to hide all cables completely behind the motherboard tray, the side connectors may be slightly visible in some cases.
  • Gamers building a mid-range to high-end system (e.g., RTX 4070 / 4070 Ti)
    750W provides ample headroom for a Core i5/i7 or Ryzen 5/7 paired with a 300W-class GPU. The native 12VHPWR connector keeps the GPU power cable tidy. Not recommended for RTX 4090 or dual-GPU setups, which require 850W or more.
  • Users who prioritize silence
    The zero-RPM fan mode keeps the fan off under typical gaming loads (up to ~40% load). Even when the fan spins, the 140mm FDB bearing is very quiet. Great for living room PCs or quiet office environments.
  • Long-term system owners
    With a 10-year warranty and high-quality Japanese capacitors, this PSU is built to last through multiple system upgrades. ATX 3.0 and PCIe 5.0 support ensure compatibility with future hardware standards.

Things to Consider

The side connector design is innovative but not universally compatible. Some cases with very tight PSU compartments (e.g., those with bottom-mounted HDD cages or narrow PSU shrouds) may not provide enough clearance for the connectors. Always measure the available space before buying.
At 750W, this unit is not suitable for extreme high-end builds. If you plan to use an RTX 4090 or a heavily overclocked Core i9/Ryzen 9, consider the RM850x SHIFT or higher. For most single-GPU gaming rigs, however, 750W is more than sufficient.
Compared to competitors like the Seasonic FOCUS GX-750 or be quiet! Straight Power 11, the RM750x SHIFT offers the unique side-connector feature. If you don't need that, the other options may be slightly cheaper or quieter. But for cable management enthusiasts, the SHIFT series is a game-changer.

FAQ

Q: Will the RM750x SHIFT fit in my case?
A: It fits any standard ATX case, but you need at least 2-3 cm of clearance on the side where the connectors are located. Cases like
