This article covers Corsair RM750e (2023) Fully Modular Low-Noise ATX Power Supply.

Overview

The Corsair RM750e (2023) is a fully modular 750W power supply unit with 80 PLUS Gold certification. It complies with the Intel ATX 3.0 standard and includes a native 12VHPWR connector for PCIe 5.0 graphics cards, making it an excellent match for modern GPUs like the GeForce RTX 40 series and Radeon RX 7000 series.
This PSU uses 105°C-rated Japanese capacitors for stable power delivery and long-term reliability. It also supports Modern Standby for fast wake-from-sleep times and improved low-load efficiency. The 120mm rifle-bearing fan features an optimized fan curve that keeps noise levels low even under full load.
Positioned in the mid-range segment, the RM750e offers an outstanding balance of features and price. It delivers the essentials—Gold efficiency, full modularity, and ATX 3.0 compliance—at a price point that undercuts many competitors. This makes it a go-to choice for builders who want quality without overspending.

Compatibility Guide

  • The RM750e uses the standard ATX form factor (140mm depth), so it fits in most mid-tower and full-tower cases. Always check your case's PSU clearance before buying.
  • It works with any motherboard that has a 24-pin ATX connector, including ATX, Micro-ATX, and Mini-ITX boards.
  • Two 4+4-pin EPS12V connectors provide ample power for high-end CPUs like the Ryzen 9 or Core i9.
  • One native 12VHPWR connector supports PCIe 5.0 GPUs directly, eliminating the need for adapter cables. Four additional 6+2-pin PCIe connectors cover older GPUs or multi-GPU setups.
  • Eight SATA connectors and four peripheral 4-pin connectors handle storage drives, fan hubs, and other accessories.

Product Info

The Corsair RM750e (2023) launched in 2023 and carries a 7-year warranty. Its 80 PLUS Gold rating ensures at least 87% efficiency under typical loads, reducing electricity costs and heat output.
In terms of market positioning, this is a mid-range PSU. It offers the key features enthusiasts demand—Gold efficiency, full modular cabling, and ATX 3.0 support—at a price that often falls below ¥20,000 in Japan. For builders on a budget who still want quality and future-proofing, the RM750e is a compelling option.

Best Use Cases

  • Mid-range gaming PC builders: If you're pairing a Ryzen 5 / Core i5 CPU with an RTX 4070 or RX 7800 XT, 750W provides plenty of headroom. The fully modular cables make cable management a breeze, improving airflow and aesthetics.
  • Noise-sensitive users: The 120mm fan runs silently at low loads, and the optimized fan curve keeps noise in check during gaming sessions. It's a great choice for a quiet home or office PC.
  • Users planning future upgrades: ATX 3.0 compliance means this PSU is ready for next-generation graphics cards. The native 12VHPWR connector also avoids the need for clunky adapters.
  • Cable management enthusiasts: With a fully modular design, you only connect the cables you need. This keeps the inside of your case clean and improves airflow.

Things to Consider

  • 750W may not be sufficient for top-tier GPUs like the RTX 4090 or RTX 5090. If you plan to use one of these, step up to an 850W or higher unit.
  • The single 12VHPWR connector means multi-GPU setups with high-end cards are not supported.
  • The 120mm fan is smaller than the 140mm fans found on some competing units. Under sustained heavy load, it may spin faster and produce more noise.
  • Prices fluctuate, so it's worth checking price comparison sites before buying. Occasionally, the higher-wattage RM850e or the more premium RM750x may be available for a similar price.

FAQ

Q: Can I use this PSU directly with a GeForce RTX 4070 Ti SUPER?
A: Yes. The RM750e has a native 12VHPWR connector, so you can connect the GPU without any adapter. The RTX 4070 Ti SUPER has a recommended PSU wattage of 700W, so 750W provides adequate headroom.
Q: Will this PSU fit in a Mini-ITX case?
A: Probably not. The RM750e has a standard ATX size of 140mm (depth) x 150mm (width) x 86mm (height). Most Mini-ITX cases require SFX or SFX-L power supplies. Check your case specifications carefully.
Q: How much difference does 80 PLUS Gold vs. Platinum make in real-world use?
A: At 50% load, Gold is 87% efficient and Platinum is 89% efficient—a 2% difference. This translates to a few hundred yen per year in electricity savings. However, Platinum units run cooler, which can be beneficial in cases with restricted airflow.
