No, the zero RPM mode stops the fan at low loads for silent operation. It spins up when needed.
Yes, the RM1000x Shift includes the 12V-2x6 connector for PCIe Gen 5.1 graphics cards.







The side interface is genius. I connected everything easily and the case looks clean. 1000W is plenty for my RTX 4090. Zero noise at idle. Highly recommend.
Excellent PSU. The 80 Plus Gold rating is real – my system runs efficient and cool. The micro-fit cables are a bit stiff, but they look great. Very happy with this purchase.
The unit is solid, runs quiet, and looks great in white. However, the cables are a bit short for a full tower case, especially the 24-pin. I had to route carefully. Otherwise, excellent.
I've built many PCs and this is the first PSU where I didn't struggle with cables. The side connectors make it super easy to plug everything in before mounting. The fan is silent and the unit stays cool. ATX 3.1 is future-proof. I'm going to buy another for my server.
Feels heavy and well-built. The white color is a nice touch. The modular interface is very convenient. My system runs stable even under heavy loads. Would recommend to anyone.
Good power supply, but I found the shifted connectors awkward for my case. The cables are also a bit difficult to bend. If you have a case with enough room, it's fine. Otherwise, a traditional unit might be easier.
Zero RPM mode is great – the fan doesn't even spin until needed. My PC is whisper quiet. The modular cables are high quality and the white finish is beautiful. It powers my i9 and 4070 Ti without any issues.
I like the side interface, but the included cables are a bit stiff and not as flexible as I'd like. The unit itself is excellent: quiet, stable, and looks sleek. Very good value for the features.
