Great Power Supply at a great price!
After having a new MSI ATX3.1 power supply blow and take out have my components I decided to try this Red Dragon power supply and I have to say I am beyond impressed. The build quality is excellent and at first I thought the ARGB fan was just a gimmick, but it comes through on the back of my daughters Lian Li 011D case and looks awesome. Also Red Dragon includes a power supply tester and MSI does not, which would have been nice to have. The cables are not the highest quality I have ever seen, they are good and work just fine though. Overall this power supply compares very well to my Corsair RM1000x. While the Corsair has better cables, both power supplies generally are very close on all other features. Both use Japanese CAPs, both are quiet and considering the Red Dragon power supply was considerably cheaper I would have to lean towards the Red Dragon if I ever need another power supply. Really, you can't go wrong with this power supply.

Worth the price. Easy install
Stress tested and no issues raised with it. Fits right into my musetex case with no issue. Came with all of the cables I needed and frankly they didn't feel cheap. The RGB is direct and you have no control over it aside a button that changes the colors and modes. For 80 bucks a psu that has 5 years of warranty. Gotta love it

Works great. good quality.
Works great. Giving 4 stars because of the following issue: I had this delivered to me for my ITX server, but it will not turn on. I asked for a replacement, and they sent one quickly [ good customer service] , but the new one will also not work. It turns out that the main Motherboard cable was bad. The unit itself works perfectly. I have been using it as a server with 3 VMs on a constant load, and the power unit is very silent and works great. I will recommend this brand. Cables are well labeled for easy matching with your motherboard pins. Note: Do make sure all your pins are securely clicked in. Pins are a very tight fit, which is great for long-term durability.

Read if you have NO experience with PC’s
So let me start by saying I’m a mid 20 something’s male, so I have *some* understanding of technology mostly Xbox and PlayStation with some VR. I’ve never owned a “Gaming PC” before my current one. The only “pc work” I’ve done prior to installing this PSU for a new GPU to be installed was pulling old RAM sticks and adding new ones. I didn’t even build this PC myself (ghost gaming sky tech), it’s a prebuilt so I have no experience in PSU swaps or anything. If you just follow the instructions and actually use common sense and your eyes in the mobo/gpu/etc you will find this SUPER SIMPLE!!! I was SO SCARED I’d ruin something. The install was FLAWLESS and booted right up. I am so happy cause this has allowed me to run a WAY BETTER GPU than what came originally in my PC thanks to this PSU, it’s ran now for 2 months only being power cycled once and it hasn’t hiccuped at all. It worked perfectly with my new RTX5060 TI, and works flawlessly with the ASrock b560M motherboard, it was a phenomenal value and the length of cables were perfect for my midsize case. It even includes special connectors for compatibility with the more weird gpu’s and motherboards. I’d buy it again and it has LED lighting which ties into my whole PC theme!

Red Dragon Keyboards/Mice are great, but can't say the same for their power supplies
I have purchased Red Dragon peripherals in the past and never had an issue, but recently purchased their power supply (RGB 850 watts) to replace an evga 650 watt power supply. There was nothing wrong with the evga, but figured I'd upgrade since I have a RTX 3080 in the PC. Red Dragon PSU was a good deal so I grabbed it, but unfortunately, the power supply would not turn on, after installation. I disconnected everything and only connected the motherboard and still nothing. I should had known there would be an issue when the RGB for the PSU would not even turn on. I will be returning this PSU and fall back to my EVGA for now. I still like the Red Dragon keyboards and mice, but don't think I will purchase any other type of hardware from them. I may had received a defective unit, but given the time it takes for wire management and everything, this first impression was a let down..

6 month review
Have been in heavy use for at least 6 months now. Still working flawlessly and the rgb ring is a nice touch. Fully modular is always a big W. Easy install, silent to my knowledge as my gpu is quite loud. Overall very happy
