    • great PSU with a solid rep for quality
Review Image by sango_wango sango_wango
This PSU was slightly longer (as indicated) than any of the ones I've had before, and it was a bit of a tight fit in my Corsair 4000D mid-size case. It worked out fine, but I had to plug in all the modular cables before inserting the PSU itself due to the tight fit to get things in there nicely meaning I'd have to take it out if I needed to plug in any additional cables in the future. ... show more

    • Easy Install, Gets You the Power You Need
When I purchased my last computer, I was a little disappointed that it only came with a 650W power supply. I mean, come on, the GFX card needed 600W alone! Well, this item solved my problem. It was easy to install and you only hook up the cables you need, so your build looks a LOT cleaner!

    • Make sure to use the right cables
This was my first time upgrading a power supply. I thought it was supposed to be easy but the cords were different. The old one used 3 4 pin connectors to power the motherboard. Corsair doesn’t come with 3 4 pins so I freaked of course. But After some research I only needed to use one 8 pin, everything powered up nicely and is nice and quiet! Can’t wait for my 3080 to come in :} ... show more

    • Worth it for the cash
Bought it to power with my RTX 3060Ti + 7 3700x and does it very well with low fan noise, fully modular helps keep the cable clutter to a minimum

    • Pretty good
Like its modular setup along with its 850W rating, dont have to worry about using this PSU all the way. The box was damaged along with its wrapping but everythings here and working.

    • Greatly improved my coil whine
I had a 10-year-old Corsair CX600M PSU, and I was trying to run my new RX 6800. It ran, but there was terrible coil whine from bothe the PSU and the GPU. It was giving me a headache. I upgraded to the RM850, and the PSU coil whine is gone. The GPU coil whine is almost entirely gome now too. It's very quiet at least and is at a tolerable level. ... show more
