    Power supply is pretty great, I love the fact that I don't need to have all those wires to have to deal with. When you need that extra space for your build and now you got to find places to store the wires instead, well that makes you mad.

    Great power supply, toggleable rgb halo. Comes with plenty of cables. Red connectors are nice for red GPUs. Using this on a 5900x and 3090 kingpin. Its still possible to trip OC protection with aggressive overclocks, though.

    Upgraded to the 3090 GPU so had to up my PSU. Had the Thermaltake 650W and was happy with it and I am equally happy with the 850W. Well made, great design and the inputs are well placed. The RBG is limited with color but it's a nice touch. I'm a fan of this brand and will remain one!

    Great Power Supply

    I purchased this power supply because I was building an older computer (windows xp), because i was bored and wanted to play some older games that i had sitting around (lol). I could have went cheaper, but bought it as a back up in case my 1200 watt psu goes bad that's in my main computer (windows 10). I dropped one star from my rating because it is missing a connector that should be included (20 pin motherboard to 24 pin psu). They include a floppy adaptor and should include the motherboard adaptor. It's still a great power supply.

    After browsing and reading all the reviews. I chose this thermaltake PSU, mainly because : - a well all around performer - great features(RGB, silent capability) - affordable price - it's a well known ThermalTake! No cons so far!

    I’ve been using this power supply for over a month and have had zero issues. While they do give you plenty of cables, I can’t rate this power supply 5 starts because they aren’t braided or sleeved.

    Works great. Maybe not enough for my RTX 3080. The RTX is very power hungry and I have a cpu water cooler as well and RGB everything. Sometimes, when i start up the computer it will turn off. Not the power bricks fault tho. It will still run without any issues once up and going. I most likely will run it with a differnt card and motherboard. I bet the Rtx 3080TI would be fine

    the power supply works great but the rgb, not so much. there is a single button on the power supply that allows you to cycle through a few colors. there is no software available to adjust the rgb any further

    Great power supply! Modular, so it doesn't take up anymore room than you need it to. The rgb fan is able to be shut off with the rear button very easily. Runs super quiet even under load
