Thoughts on the 750W Corsair RM750e PSU
Posted by Azza449@reddit | buildapc | View on Reddit | 19 comments
Hi all,
As you can see from the title I am just wanting to get some opinions on whether this PSU is both reliable and trustworthy, as well as will it be okay for my pc build I am thinking of getting. The link below should hopefully take you to it. If not, I will post the specs below.
If this PSU is not good. Then what other options (that the company I am using offer) would be good? Ideally I don't want to go into the 1000W, as I am already over my budget.
Thanks in advance!

Regarding the PSU: Check out the PSU Tier list. RMe falls under Tier A, so you're fine brand-wise.

Okay great! Thanks for that. Do you know if 750W will be adequate to power the build?

I would say yes. The GPU is the main driving factor. A good practice (in my opinion) is to check the GPU recommended PSU rating and add 20%. The recommended rating for a 3070 is ~~600W~~ 650W. So if you add 20%, that's ~~720W~~ 780W, so the ~~very next~~ closest one is 750W. You can go higher if you feel like you will be upgrading your GPU within the next year or two, but I say just go with 750W, especially if you are on a budget. Another reason for getting an 850W PSU is if you are (really) hypersensitive to noise and don't want the PSU fan kicking in while gaming.
Edit: sorry, corrected the ratings. Also, you may opt for an 850W if you will be pushing the card and CPU to their limits and would like to be on the safe side.

Bruh I will necro this because that's a terrible practice. Manufacterers' recommended PSU wattage are always exaggerated, a 3070 will at max consume like 250W, even a good 500W PSU will do just fine.

RM750e is noisier than RM750 and RM750x according to Cybenetics tests. Its noise level rating is only standard++, whereas RM750(2019) got A, RM750x(2021) got A-. However, it has smaller form factor and is cheaper.

For those who want to buy RM750e and encountered this post, I used it for a year and never noticed its noise. In fact, you need a REALLY sensitive ear in order to hear it and wearing a headphone cancel it 100%.

Ive got to say that i have been using it for about 6 months and the noise bothers me alot
Correct_Fish2930@reddit
got a new rm750e at it has absolutely 0 noise. hope the fan is working ahahahah
benson33@reddit
Good luck man i switched it out for a sc750 annd it works great
My pc is in a ssupd meshroom s case so sff is better in the first place
SlideSensitive7379@reddit
maybe you got unlucky and got a bad model.
my pc case has a lot of airflow and i never hear it.
the only thing i hear with the psu is a click when i turn the pc on and off, which i was not used to until i got this psu.
It is strange how you are able to notice the noise, do you have like Noctua fans on your PC and the RM750e is the only non-Noctua fan in your pc? This is the only thing i can think that will explain how you are able to notice the psu noise.

I can't really hear it when I'm not doing anything heavy on my PC and when I am running it harder the rest of my fans easily drown it out. Perhaps if you have a Noctua or silent tuned PC the noise would be a bigger deal but the conventional fans in mine and the ambient noise makes the psu effectively inaudible for me

I believe this new Corsair PSU started life as the Corsair CS750 80+ Gold Fully Modular Power Supply. Corsair must have recognized they made a mistake with naming this new power supply and bumped it up to the RM line where it belonged in the first place.
I have a Corsair Vengeance PC from about 1 1/2 years ago and it has this exact PSU, just labeled as the CS750. Corsair's website has recently taken down the page for the CS 750 and now shows it as the RM750e.
It is a good power supply. I have had no problems with it in my Vengeance PC in the year and a half I have had it. It is basically silent and powers an i7 11700 and RTX 3070 just fine. Rock stable 12v.
Here is link to picture of it in CS mode. I'd upload pictures if I could.

Hmm, found a page they still have up:
https://www.corsair.com/cn/en/p/psu/cp-9020239-cn/cs-series-cs750-750-watt-80-plus-gold-fully-modular-atx-psu-cn-cp-9020239-cn
Compare to RM750e:
https://www.corsair.com/ww/en/p/psu/cp-9020248-eu/rme-series-rm750e-fully-modular-low-noise-atx-power-supply-cp-9020248-eu
Only difference in specs is the +3.3 and +5v rail output is listed on the RM at 150, and at 110 on the CS, but on both Max load for +3.3 and +5v is 20 amps. These are the exact same power supplies, just renamed. If any rep for Corsair wants to add any input, please do.
Whatever its called, it is a very good power supply.

Hey , so you think the rm750e is good like really stable and reliable am planning to get a 750w but am debating at the moment any tips help
MTCMayhem@reddit
I have not had any problems with mine for 2 years now, and I believe the RMe series come with a 7 year warranty. You could also get the RM750 one, not the RM750e, and I believe that one has a 10 year warranty.
Corsair has good power supplies, and they have good customer service, so I think you are fine with either one.
Patient-Researcher31@reddit
Where to buy that?
MTCMayhem@reddit
NewEgg or Amazon have the Corsair RM and RMe power supplies. The one I mentioned above is still working great, and I now have an RMe 1200 in my current build that I bought from NewEgg.

Hey! I was looking into buying the RM750e and was wondering if you'd recommend it. Thanks!
Klutzy_Rutabaga1710@reddit
No. The RM750e uses chinese caps. Get the RM750x (2021) which actually uses Japanese caps.
RedCaballero1@reddit
Thanks for the advice!
