The RM1000x Shift is more than a power supply—it's a cable management revolution. The side-mounted interface is perfect for builders who value aesthetics and airflow. With a 10-year warranty and high-quality components, this PSU is designed to outlast multiple system upgrades, making it a smart investment for any high-performance PC.
Yes, the PSU supports standard ATX mounting. If your case has a bottom vent, orient the fan downward for better intake airflow.
It places all cable connections on the side, making them easier to reach and route, reducing cable clutter and simplifying installation in small cases.
Yes, it includes a 12VHPWR cable and is PCIe 5.1 compliant, designed for the power requirements of high-end graphics cards.
No, Zero RPM fan mode stops the fan at low and medium loads for silent operation. It only spins up under heavy load or high temperature.












The side interface is brilliant! No more reaching behind the PSU to plug in cables. My build looks so much cleaner and tidier. The unit is fully modular, so I only use the cables I need. It's also quiet and efficient. Highly recommend to anyone building a new PC.
This power supply is excellent. The build quality is premium, and the side cable interface makes installation a breeze. The 1000W is more than enough for my RTX 4090 and i9-13900K. It runs cool and silent, and the 80 Plus Gold rating means it's energy efficient. Worth every penny.
The side interface is a neat idea, but it requires some planning since the cables come out from the side. If your case doesn't have enough clearance, it might be tricky. Once installed, it's great. The PSU itself is reliable and quiet. Overall, I'm happy.
I've built several PCs, and this is the easiest PSU to install. The side cables are a game-changer. The modular design means no clutter. The unit is silent, and my PC's cable management looks perfect. This is my go-to PSU from now on.
The PSU is great, but be sure your case has enough room for the side connectors. In my case, it was a tight fit and I had to bend the cables a bit. Once installed, it works flawlessly and is very quiet. Just make sure your case is compatible.
I upgraded from a 750W to this 1000W unit, and it's been flawless. The side interface is so convenient; I don't have to reach into the back of the PSU like before. The cables are high-quality and the unit is silent. I'm very impressed.
The PSU works fine and is quiet, but the side interface doesn't offer a huge benefit for my build. It actually made the cable routing a bit more complicated because the cables stick out to the side. It's still a good PSU, but I don't think the feature is a must-have.
I wanted a clean look for my RGB gaming pc, and this PSU helps achieve that. The side-facing cables make it easy to route everything neatly. The modular design is great, and the fan is silent. I'm very pleased with the purchase.
The PSU is great quality and runs silently. The side interface is innovative, but it took me a bit of time to figure out how to route the cables with my case. Once it's in, it's great. The 80 Plus Gold efficiency is a plus, and my electricity bill might be a bit lower.
This is the best PSU I've owned. The 1000W gives me headroom for future upgrades, the 80 Plus Gold ensures efficiency, and the side interface is pure genius. Installation was smooth, and the PC looks immaculate. I can't recommend it enough.
Works perfectly. No issues.
The PSU is fine, but I had a minor coil whine under load that went away after a few days. The side interface is interesting but didn't make a big difference for me. It's a quality unit, but I'm not sure it's worth the premium over other ATX 3.1 PSUs.
