    Upgraded from a 20 series card to a 50 series card and needed a 12vhpwr cable, went with this corsair and so far so good, playing for long hours and the only warmth im feeling on the cable is from the fans blowing the hot air off the card on to it. Stable, and works great.

    Install just like any other power supply. No problem with noise issues and got it on sale. I have only been using the power supply for a week so we’ll see how it goes.

    Replaced my nearly 10 year old RM 1000 with this one for my new build and couldn’t be happier. The other one was still working when I replaced it. Corsair has upgraded the cables that come with the PSU. They are no longer in those awful woven sleeves that don’t bend. Much easier to route the new cables.

    I needed new power supply for my pc and this one was a good price for the wattage and it fits inside my case. It's got plenty of power and wattage to support anything and runs really quite, and it was easy to install and came with all the cables needed to hook everything back up. I would recommend this particular unit to anyone and the also the brand as well. It's quality is really good and run any pc for years to come

    Cosair has a way of showing off how "Power-ful" it is! Competes with big dawgs but affordable for all. I would recommend this. Easy to install and works quiet and good.

    Excellent PSU. Upgraded from the old RMX1000 (20201) to this version and my coil whine is completely gone, RTX 4090, i7-12700K based system. Not saying this will fix it for you if you have this issue, but I am incredibly happy with it, as I tried swapping out a bunch of other components, including the GPU itself, motherboard, ssds, and it didn't fix the issue.

    I got this power supply for my gaming PC and it's absolutely fantastic! The cables look great and it has zero issues pushing my hardware (not too surprising considering this is a little overkill for what I'm running) I absolutely love it!

    This currently powering my main setup . plenty of connections easy to use with plenty of power for future upgrades . If I was to purchase another Power supply I would definitely look at the corsair shift series ... The cables attach to the side on those ..

    Great PSU -- Unlisted 12VHPWR power rating.

    Everything about it works great, however the included 12VHPWR was only rated for 300W. The specifications make no mention of the power rating of the 12VHPWR cable. When running the cable on a RTX 4080, it caps the power draw at 290W when the card is capable of 330+W and has more to give. If buying this PSU, check what your cable is rated for as there are multiple cable versions available like the 450W and 600W that your GPU may need.
