I was having stability issues with my PC and suspected my PS may be too weak for my GPU. I saw this PS reviewed at Jayz2Cents and I liked the idea of the flexibility. Being able to rotate the plug means you can have a traditional PS with the cables out the back or a shift PS with the cables out the side. It may seem gimmicky until you try it yourself.I tried it both ways and decided to go with the shift configuration so the cables connect on the side. This makes cable management so much easier. I pull the side panel off my tower and there are all the connections easily viewable and accessible.

Although this was the wrong PSU for my case these things are solid as a rock and good quality. I've used one of their PSUs before and had it for roughly 8 years with no problems at all with it, ran like a champ powering two high end GPUs 8, sata drives, 4 m.2 nvme drives, 360 AIO cooler and 12 high end turbo fans pushing 2500 rpm airflow, plus a 2k touch screen display on front of case and about 11 USB Hubs hanging off of it all atuffed with little 4TB SSD drives.
Hello, Thank you for fast delivery. I cannot image that this PSU has USB FAN HUB and also 90 DEGREE AC. This is an awesome feature that i needed for my build. My previous psu does not work and this will be used for my new build. It comes with a rotational ac which is a nice feature depending where i am going to install and also the USB hub. I do not need to buy an extra USB hub as i always needed to have extra USB beacuse motherboard internal ports are enot enough and with this hub , i do have option to separate and use it like normal usb hub or i can connect on the psu as another internal hub
Está muy completo en cables
It does what it says it does
The Lian Li RS1200G 1200W Rotational Shift Fully Modular ATX Power Supply is the latest addition to the collection of tech for my new PC build. While I'd have preferred the white color option (to match my build), the novel innovation of the rotatable AC inlet offers a level of versatility that I've never seen in any power supply before. As we add more and more components to our tech over time, a power supply such as this allows us to ramp up as our system needs grow. This is a real upgrade for me, and I'm pleased to be on the cutting edge with this amazing piece of tech. I can't wait to see wh
This is a beast of a power supply. I have the 1200W model, and I've seen 1000W people having trouble with it and saying the cords aren't great. However, the 1200W model's cords seem perfectly fine, and I haven't had any issues with the quality. I like that this lets you flip the power port around based on your case, but I feel like that's never really been a huge issue for me in the past. However, I love multifunction. It does help that this is Fully Modular and easy to get all the cords, along with add-on ports for other devices. The noise level is about average with what you'd expect of a po
