  1. Hunter –

    Looks good. Even better that you can customize what you connect.

  2. Unknown –

    It arrived on time, and it does it’s job well. No issues so far, and the white really fits with the aesthetic of my PC. It came with a bunch of extra cables that I didn’t need.

  3. JinTA –

    Bought this power supply for my new custom white build. It’s been about a month and I haven’t run into any hiccups.

  4. Aqua –

    Every wire came as white which was pretty nice. Nothing shorted or anything and still running strong.

  5. TenaH –

    Awesome power supply, perfect for a all white build. Highly recommended.

  6. Seigyo –

    Easy to install, white finish and cables match my case well! The only downside is that the PCIe cables are a little ugly where they split off into 2 x 8 pins.

  7. DerekS –

    So far so good. Love the cable management and cable slots instead of all cables already attached

  8. Vian –

    Love the white cables, modularity is nice too. No complaints

  9. BigDawg1172 –

    The best psu I’ve purchased so quite i got this to go with my new rtx 4070

  10. alex –

    I have had no issues with it and does great paired with my 4070 and i7-13700k. looks good too!

  11. RicardoG –

    Works perfect for my current setup will 100% recommend

  12. Vince –

    I needed a power supply unit that would fit my HYTE Y60 case and this did the job perfectly. Output of power is great. Great price too.

  13. Lucas –

    I bought this to replace my EVGA Gold power supply dying within 5 years (I know, I’m surprised too). I saw this Corsair power supply was white and liked that it stood out compared to all the black and greys. Works like it should. Would recommend.

  14. Kevin –

    Very good power supply. I have it hooked to a 4070. The fan RARELY comes on. When it does it’s silent.

  15. JorgeR –

    well, there’s no much things to say, it is what it says, I love that is full modular and not too expensive for ir, enough to supply a 4080

  16. MarcosP –

    More than what I needed, easy to install, fit perfectly.

  17. Chris –

    i replaced a 700w with this 850w and after 2 months it started making a loud buzzing noise.

    Best Buy will not do a return after 14 days which is ridiculous.
    i will not shop at Bust Buy again

  18. Shattered1Plain –

    Love the modular design and easy to understand labels.

  19. GregoryC –

    I have a white case so Inwas going for that look. The modular cables even on this thing are white which was a huge surprise and made my build pop. The power itself is amazing, its powering my 5900X and a 7900XTX which needs consistent power. This did the trick.

  20. Zeddrick –

    Quality PSU, braided 24pin MOBO cable. lots of SATA cables. I always trust Corsair PSU’s and cases.

  21. RTXCUSTOMZ –

    Very stable and quiet PSU and the white connectors look very high quality. I love this setup on my RIG. Really flashy

  22. NikitaG –

    Достоинства
    Мощный. Бесшумный. Гарантия 10 лет, производитель явно уверен в качестве своего продукта

    Недостатки
    Недостаток в комплектации, зачем людям 3 провода питания процессора и всего 2 провода питания видеокарты, да они разделяются ещё на 2 и получается 4 на 8 pin PCI-E но кто в здравом уме будет запитывать 3090 раздвоенным проводом питания, надо на каждый разъём отдельный провод. Тем более выходы на блоке для них есть свободные. Поэтому заказал отдельные провода для подключения видюхи, благо в интернете полно предложений проводов PCI-E именно для серии Corsair RM

    Комментарий
    Отличный надёжный блок, но дополнительный провод питания видеокарты надо бы докинуть в комплектацию. Тем более скоро выходит 4000-я серия с 12 пинами, а там желательно иметь переходник с трёх отдельных 8 pin на 12 pin

  23. OfficialRewind –

    Looks good, works great, and supports the power requirements of my upgraded system!

  24. Chris –

    Great Power supply, looks good in my case. Using it for a system with a 7600x and 7800xt and more than enough power to spare. Includes white cables, so make sure that fits the aesthetic of your build. Stays cool and quiet and even shuts off fans when not using a full load.

  25. Ghostpants –

    You can never go wrong with corsair products specifically their power supplys.

  26. Isaac –

    This power supply looks great with my build and works perfect

  27. NathanaelM –

    Recently I started making some upgrades to a PC I built a few years ago and I obviously had to start with a new power supply to make sure the rest of the new hardware would run smoothly once I had it installed.

    This Corsair RM850 has met all of my expectations and has run super quiet, which was really important to me.

    It installed really easily, and having things labeled made getting my entire system connected and back up and running a really smooth and quick process.

    If you’re in the market for a reliable power source that won’t break the bank, I would definitely recommend this one.

  28. Myun –

    Good psu I like that it came with white cords but i still got cable extensions for a cleaner look, corsair is a reliable brand.

  29. Crist –

    So many cables! Loved that when I was installing, I had so many options for cable management. Nice and quiet too!

  30. Epic –

    Runs everything flawless and its white full modular

  31. BraulioG –

    perfect for my set up, also a good size an colors!

  32. Buyer –

    Works on my PC with 4080 FE and 13600KF. No issues at all!

  33. ClintonW –

    Very nice power supply. Has all the cables I need and are very good quality

  34. Mocha –

    Bought for my new computer and works wonderfully!!

  35. DevanC –

    Works perfectly! Only thing that could’ve been better is if the cables are individually sleeved but I guess I’m asking too much for the price.

  36. Buddy –

    This power supply is great! It works well for the price and I had no trouble installing it into my PC. I like that it’s white to brighten my PC as well, instead of all black like other power supplies.

  37. ColbyC –

    works GREAT!! love it cant wait to get the 1300..

  38. Martinez –

    More than enough power! easy to connect and use. would recommend to anyone wanting a good power supply for a good price.

  39. MohamedSamir –

    Nice product. However didn’t use it yet. Will update review later

  40. user579325 –

    White as stated, no issues with my new pc setup. Item comes as advertised

  41. Timothy –

    Works great, and has enough slots for a 4080, with extras just in case. Put mine into a hyte y60 case and even with the added molex monitor, theres still tons of room.

  42. JdW1 –

    850w gold rating and the cables are white with no ketchup and mustard cables. Fully modular makes it easy.

  43. Jagger –

    Great power supply for a 7800 xt it’s fully modular and perfect for white builds.

  44. Eunice –

    Came in well packaged.

    Building a new pc with this guy. Just the right size. Used pcpartpicker to know if it fits my pc case. Hope it works fine when I finally get to build it.

  45. Psyi –

    I knew the quality and design would be great, but also really impressed with the looks!

  46. John –

    Works Great! installed a i7 12700k and 4070 and everything works great with no flaws!

  47. Noah –

    850 watt psu is more than enough for majority of high average gaming pc’s. I have a 4070 ti and it runs great. The white cables are also a nice detail. Overall you get alot for how decently its priced, especially when you get it on sale like i did.

  48. JustinK –

    Works perfectly have had it for a while now. Perfect power

  49. ThomasM –

    The RM850 power supply from Corsair is a beast! The 80 PLUS Gold efficiency ensures stable power delivery, and the fully modular design keeps cable management a breeze. With 850 watts, it’s a powerhouse capable of handling demanding setups. The Zero RPM fan mode keeps things quiet during low loads, and when it kicks in, it’s still impressively silent. Whether you’re a gamer or a content creator, the RM850 is a reliable and robust choice for powering your rig.

  50. Alister –

    I’d highly recommend this psu it’s long lasting quiet and gives enough power for my setup I’m glad I chose this power supply and continue to stay with Corsair best company around
