Review: Great 850w Power Supply Unit Highly Recommend - This is a great power supply handled my Ryzen 5 7500F and RTX 5070 Ti with a ton fans and aio. Also has the 12v-2x6 ATX 3.1 connector for my GPU which is nice as well. No problems at all the smart zero fan mode is also nice so it doesn't come on at low loads when it doesn't need to. Cables are nice as well and the psu is nice and compact so it was easy to install in my case which is the Montech XR. It is much better compared to my older unit I use to have it will also allow me to get stronger upgrades for PC parts in future if you need to.
Review: Quiet & good value on sale - Got a pretty good deal & the cables were easy to sort & easy to manage as well. Noise level is non existent & the cable quality was also great to replace my daughters faulty one

### ⭐⭐⭐⭐⭐ It's Working Fine and Was Easy To Install
*by -***Z on February 2, 2026*

This power supply replaces a smaller one that was failing. I have 10 internal drives and this PSU is larger so should handle the power requirements. I did figure the power needs of the MOBO along with the various cards, including the GPU, and drives along with my CPU water cooler. This 850W PSU will handle load.
