I have this Corsair RM850e powering my Work/gaming computer. PC Part Picker only calls for maybe 550 watts, but I wanted something a bit overkill just in case I upgrade, etc.This Power Supply has not let me down. Only had it about 6 months and it rocks. Powerhouse and never has skipped a beat.10/10 would recommend!

    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.

    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.

    The power supply in an older Dell computer died so needed to be replaced. This Corsair PSW fit perfectly in the case and I particularly liked the modular cables so that I only used the ones needed and didn't have a lot of loose ones to deal with. The unit is also whisper quiet. I did have a problem finding a 4 pin connector needed for the CPU but found that the 8 pin one actually was able to split apart and worked great. Took a star off since it was fairly difficult to find info on this and finally stumbled upon a note about doing that. Great purchase and recommended.

    when my old noname psu started to make trouble,
    i did some research, mostly at cultist's psu tiers list and have chosen this psu - tier a, available and most reasonable price, (750w, atx 3.0 & pcie 5.0 for future proof for some planned midrange rtx 5000 gpu)
    until this psu arrived i used some replacement psu (tier f) from computer lab guy .
    replacement psu was actually new one with box.
    so essentially i have experienced using 2 new out of the box psu recently.

    i write all this to talk about coil whine.
    f tier replacement cpu started quiet and after 1 hour loud coil whine began. i had just turn off pc at night. i didn't really care because i knew it was a temporary one.
    interestingly, after 1 week of coil whine - it mostly disappeared and tier f psu worked almost silently.

    after this cpu arrived - it had similar coil whine pattern: start silent, then some period of coil whine, than silent. probably because it's tier a - coil whine period was much shorter - 2-3 days.

    so people complaining about coil whine probably should give a psu some chance before rma.

    except that, psu is just working (now it's 1 week since installing). my general load is way below 750w, probably less than 20% of it, so psu fan is just idle not spinning - best outcome for silence.

    I’ve been using the Corsair RM750e for about two weeks now, and I’m really happy with it. This power supply works great and keeps my system running smoothly with no issues. I’m running it with an RTX 4070 Super, a Ryzen 7 5700X3D, and a Peerless Assassin 120 SE ARGB cooler. Even with all these components, I’m left with a good wattage buffer, which is reassuring.

    Installing it was easy because the modular design helps a lot with cable management. What I love most is how quiet it is—seriously, I hardly hear it even when I’m gaming. The efficiency is good too, which means I'm saving on power bills. I installed everything two weeks ago so when I got my power bill yesterday, I actually noticed a slight reduction in power consumption compared to last months bill using an old bronze-rated psu. That's only 2 out of 4 weeks of primary use.

    The price feels fair for the quality you get, so it’s a solid value.

    Overall, the Corsair RM750e is a fantastic choice for anyone wanting to upgrade their PC. It’s powerful, quiet, and looks nice. Definitely recommend it!
