I gave it 4 stars because LED cannot be controlled from MB and its manual control, which is useless

coolest power supply I've ever had. Featured a Smart Fan Zero, and a RGB fan inside, where you can only change the color of it with a press of a button on the back of the power supply.

Quiet, colorful, has the wattage I need to grow with my pc upgrades..ie: cooling loops

Diggin' the RGB lighting this thing comes with. Although it is a bit ridiculous to have on a PSU its still kinda neat. Performance wise this things kept up with my expectations and does what its meant to.

Wanted a nice, neat psu. Got this one. The rgb isn't addressable so that sucks and I had created a psu shroud in the end so it only glows underneath. Still, a good psu if you want to display it.

RGB is taking over pretty much every component nowadays, and though I did not buy this power supply specifically for its RGB elements, there are major shortcomings related to this feature. The RGB fan can only be set to 5 settings - the typical colour cycle option, red, blue, green, and white solid colours. There is no way to address the RGB LEDs through software and the lack of customisation options makes it seem very tacked-on just to fit in with the RGB component hype.

My PC definitely doesn't require 850W of power, but if I intend to add more storage or GPU upgrades to the rig it affords these, with plenty of slots of spare cables afforded.

This is very nice PSU only thing i dont like is they dont sell sleeved cable kit for it. I have extensions but would prefer actual cables

A lot more power then I needed for my build but amazing to work with. quiet and efficient. But.. Who really needs an RGB power supply, or 850W. i got it at -$30 Off so i jumped on it. but i would have been fine with 650W unit
