Customer Ratings & Reviews

Needed a Gold Sandra’s power supply for my first gaming computer. This is the perfect power supply with absolutely no noise. It is modular so use only the cables needed and route them to make the PC look neat and tidy. Super easy to install. Came with all the necessary hardware, adapters, cables, etc.

Did curbside pickup, was broufht out to my vehicle quickly. Was easy to install and instructions were clearly written. Has performed very well, no issues at all.

It's a Corsair PSU, of course it works great. Upgraded one year ago from a non-modular to this fully modular, and will never go back -- less clutter!

Great power supply. After unboxing and installing in my PC, it powered up first time with no issues. It also came complete with ALL the needed wire harnesses which were an upgrade to the originals that came with the PC. Great product.

Great power supply that can handle the spikes of the 3xxx cards. Well built 10 year warranty Quite underload Nice cable length Only con is that the capacitors are in cable so they are bulkier then normal and a bit harder to work with.

Being modular its nice and stealthy not being in the way. And it has just so much power that I probably wont need to get a new one for a while.

bought this when upping gpu to a 6800xt runs like a dream came with plenty of cables to even run 2 seperate ones to my GPU for max power

Great power supply. Fully modular makes cable management easy. Run only what you need. 850 watts is more then capable of running my system. works well. No issues.

Always trust Corsair not had any problems with them for years a reliable and robust choice for powering your rig. A powerhouse capable of handling demanding setups if you need a upgrade and can't wait just get this one and it will do it's job Plus more.

very good power source, i have been building computer systems for over 20 years and corsair has never let me down, it stays cool and i put my systems through some serious video rendering and have had over 500 images in photoshop adobe raw and it never overheats and keeps the power coming, i highly recommend it.

Easy to use and install. For most pc builds, this power supply is more than capable to run your computer. And with this being fully modular, no need to getting extra cables, it comes with all that you need!

Works amazing and no more hot delays! This power supply has surpassed my expectations, allows stability and consistent power. Definitely recommend

Bought after a thermaltake died. Was much easier to fit in my new 5000d airflow case. Wires were way more flexible than thermaltake and it made cable management easy. Very happy and fired up quick. 0 issues

Corsair has always made good, reliable power supplies, and this is no different. Fully modular, cables aren't too short or unreasonably long. Nothing more to really say

With a 10-year warranty. Very silent and name brand. I am very confident this power supply will stay with me throughout many of my upgrades and rebuilds. Worth investing in a good power supply.

This psu was easy to install and well labeled. It came with a large assortment of cables. Powers my pc like a champ.

This power supply produces plenty of power for my computer that requires power, the cables that connect to motherboard and such are easy to plug in and come with labels.

Love this PSU. Its highly rated in reviews and this is one product that corsair really did a good job on. All in all i estimate my computer to be using around 500 to 700 watts of power. This is why i chose the 850. It has just enough buffer to make sure it stays within its efficiency range. I highly recommend it!

This is the second computer I've built with this model power supply, the first one has been working hard for about a year. Love the modular for the cable management, and the quality, it has not failed me yet.

Great value. Fully modular PSU with a good power rating, easy to install and work with in general. Highly recommend
