The Corsair RM750e (2023) Fully Modular Low-Noise Power Supply is one of the best PSU upgrades I’ve made for my build. It delivers clean, consistent power with impressive efficiency thanks to its 80 PLUS Gold certification. I’m running a high-performance gaming PC, and this PSU handles it effortlessly, even under heavy loads.

    • impressive low noise power supply
Style: RMe (2023) ATX 3.0 & PCIe 5.0 Size: 850 Watts
The Corsair power supply is top-notch and delivers exceptional performance, efficiency, and quiet use. One of the biggest things I like about this power supply is its fully modular design. By allowing you to connect only the cables you need, it helps keep your build clean and improves airflow within your case. With an 850W capacity, this is ideal for high-performance builds, including systems with power-hungry GPUs. It's great for gaming pc's and content creation with ease, ensuring consistent and stable power delivery. The RM850e features a quiet 120mm fan that operates near-silently during low and medium loads. Its Zero RPM mode is particularly nice, as it stops the fan entirely during light tasks. ... show more

Happy with the purchase. No problem so far. I thought it was faulty at first because of ground issues but it was fixed by changing my extension into a 3-pronged grounded surge protector. Fan is very quiet. Sufficient power to my 7600x and Rx 6600. Cable length is just right. There's a strong rubbery smell at first when you unpackage and use it to power the pc but it goes away after a few days of usage which are all normal. It also comes with some screws for the chassis/case, a safety manual and complete modular cables as specified. Long warranty period. The item was delivered internationally without any visible damage to the box. If I have to name a cons, then it has to be some cable hook/clip being too tight or not "clicking" at all when plugged. So I really need to use force if I need to pull out a modular cable (like the mobo cable) from the psu. At the end of the day, power supply is functional and stable which is what's important. ... show more

    • Reliable Power Supply!
Style: RMe (2023) ATX 3.0 & PCIe 5.0 Size: 750 Watts
I have been buying Corsair PSU's for all of my PC builds because of the reliability and trust of this brand. I put this 750W power supply inside my custom-built machine that has a 3070 graphics card and an I7 12th gen CPU. It has more than enough power, but I would also like to have more than enough just in case I want to upgrade components. I highly recommend Corsair for their power supplies. I have had my PC with another Corsair for over 3 years now, and it is running super efficiently. ... show more

    • Worth it for the price
Style: RM (2023) Size: 650 Watts
Bought to replace a different unit that gave out on me not long after purchase. So far it has been amazing. As simple as any other modular unit to install, though the cables are more stiff than I’m used to. Connectors work as expected. Smaller than expected, but fits within standard cases ok enough. Looks good. Manages heat perfectly for my needs. Minus one start for a small but noticeable click made when the unit powers on and off. No other sound, though, so it’s something I’m willing to overlook. All together was a fantastic investment for the price, and I hope it lasts. ... show more
