CORSAIR RM750e (2025) Fully Modular Low-Noise ATX Power Supply with 12V-2x6 Cable – ATX 3.1 & PCIe 5.1 Compliant, Cybenetics Gold Efficiency, 105°C-Rated Capacitors, Modern Standby Mode – Black

A Solid Contender for Modern BuildsThe CORSAIR RM750e (2025) continues to solidify Corsair's reputation for reliable power supplies, offering a compelling blend of features, performance, and value for mainstream PC builders. This iteration brings key updates that cater to the demands of contemporary hardware, making it a strong choice for those looking to power mid-to-high-end gaming rigs.Key Features and Updates:One of the most significant upgrades for the 2025 model is its ATX 3.1 and PCIe 5.1 compliance, including a native 12V-2x6 (600W) GPU power connector. This ensures full compatibility with the latest and upcoming high-power graphics cards like the RTX 40 and even future RTX 50 series, without the need for cumbersome adapters. This forward-thinking design is a major selling point for users planning future upgrades.The RM750e maintains its 80 PLUS Gold certification, indicating excellent efficiency, particularly at typical loads (around 87-90% at 115VAC input, and even higher at 230VAC). This translates to less wasted energy, lower heat generation, and potentially reduced electricity bills.Fully modular cabling remains a hallmark of the RMe series, allowing for clean builds and improved airflow by only connecting the necessary cables. The flat, flexible black cables also contribute to a tidier aesthetic.For cooling, the RM750e utilizes a 120mm rifle-bearing fan with a Zero RPM fan mode. This means the fan remains off under low loads, resulting in near-silent operation for everyday tasks and light gaming. The fan only spins up when thermally necessary, keeping noise levels in check even under higher loads.Performance Under Load:In terms of performance, the RM750e delivers stable and reliable power. Load regulation on the primary rails is generally very good, ensuring consistent voltage delivery to your components. Ripple suppression is also strong, contributing to the overall stability of your system.While efficiency can see a noticeable drop at 115V AC compared to 230V AC, and ultra-low load efficiency might be considered mediocre, these factors are unlikely to significantly impact typical user experience. For most gaming and productivity workloads, the RM750e performs admirably.Build Quality and Longevity:Corsair has opted for a HEC/Compucase OEM for the RM750e, a reputable manufacturer. The internal components are neatly arranged, and while it might not feature the absolute top-tier Japanese capacitors found in Corsair's higher-end RMx series, the industrial-grade, 105°C-rated capacitors are still of good quality and contribute to reliable performance.The compact 140mm length of the PSU makes it easy to fit into a wide range of PC cases, including smaller form factor builds. Corsair also backs the RM750e with a 7-year warranty, providing peace of mind.Pros:* ATX 3.1 and PCIe 5.1 compliant with native 12V-2x6 connector: Future-proof for modern GPUs.* 80 PLUS Gold efficiency: Reduces power consumption and heat.* Fully modular design: Excellent for cable management and aesthetics.* Zero RPM fan mode: Near-silent operation at low loads.* Compact 140mm depth: Easy to install in various cases.* Good ripple suppression and load regulation.* 7-year warranty.Cons:* Efficiency drops more noticeably at 115VAC compared to 230VAC.* Component quality (e.g., non-Japanese capacitors) is a step down from the premium RMx series, though still perfectly adequate for its price point.* Some reports of coil whine, though this can be subjective and vary by unit.Conclusion:The CORSAIR RM750e (2025) is an excellent power supply for anyone building or upgrading a modern PC. Its ATX 3.1 and PCIe 5.1 compliance with the native 12V-2x6 connector is a significant advantage, making it ready for the latest graphics cards. Coupled with its 80 PLUS Gold efficiency, fully modular design, and quiet operation, it offers a fantastic balance of features, performance, and value. While it may not have the absolute bleeding-edge components of higher-tier PSUs, the RM750e (2025) provides robust and reliable power that will serve most users very well for years to come.

Works very well, doesn't make much noise during use unless you are doing intense stuff.Cables are of high quality and are long enough for everythingIt is very easy to setup inside an ATX case, and cables connect easily.

Overall great, quieter than my old PSU and the fan doesn't run when under light loads. Very efficient which is nice as that results in less heat being sent into the room. Super easy to install and wire as the power supply is modular. Cable length is more than enough for any size case

Great quality, solid case (as you would expect form Corsair). It is so quiet even when under a reasonable load, only making any real sound when it is really baing pused powering a high end GPU playing games on Ultra settings.

The media could not be loaded. Clicking noise, I think it's about the explode. It's 100% not something stuck in the fan. These are electrical noises.

It has a manufacturing fault which corsair acknowledge and are looking to replace them i dunno why no one has mentioned this in the comments probably gonna be getting a refund 🤔 clicking noise at certain low to moderate power draws

Great product as always from Corsair, well built and plenty of cables however a word of warning.If you are doing a small build where the PSU needs to have an internal to external power cable connected I would not recommend it due to the way the cable will need to be rotated creating small radius bend.

I have this and have heard the same noise may times, mostly in Frostpunk2 when capped at 60FPS. If i remove the cap the noise goes away. Due to the Spec of the PSU I think its flipping between 2 12V circuits and this is by design.I don't get the noise during normal operation like normal desktop workloads and just seams to be when the GPU (with the new 12V connector) is busy but not busy enough if that makes sense considering its a 1Kw PSU likely powering 500W systems in the most caseMy spec for ref:amd 9950XRTX 4070 Super64GB RAMSome Disks and a ODDAnd this PSU
