## Description

Review: Great value SFX PSU - Needed a SFX PSU for a SFF build and this checked all the boxes. For a 850w Platinum, you are getting a lot of value for the money. Cables are easy to work with and just long enough. The on/off switch extensions is very convenient since some Sff cases have the PSU sitting inside plugged into an extender leading to the back without a switch. Noise is mainly audible on start up but after boot most of the noise is canceled out by other components. It’s quiet overall and temps are good; just warm to the touch. I am happy with my purchase.
Review: Make sure you test right away! - Make sure your fully test products like these. I went to use a month later after purchasing and it did not work.

### ⭐⭐⭐ Its fine
*by X***R on 16 May 2026*

It works fine, but some of the cables are shorter then what they need to be. Be weary if your cables have to bend around corners
