RMx SHIFT PSU Compatible Cases: A Definitive List

The CORSAIR RMx SHIFT PSUs are modular power supplies (PSUs) that “shift” the cable connections to the side of the PSU. Moving the cables to the longer side of the PSU positions the cable connections along the case side panel where cable routing occurs, allowing for simpler cable management and easier access.

The RMx SHIFT comes in black or white and in the following wattage outputs: 750W, 850W, 1000W, and 1200W.

Since the RMx SHIFT power supplies are ATX PSUs, the width and height are identical to any other ATX power supply. However, the ATX standard does not regulate the length of a PSU. So the 1000W and 1200W versions are 20mm / 0.78" longer than the 750W and 850W models. For the sake of completeness though, you can find the dimensions for all of them below.

Since the cable orientation of the RMx SHIFT is different from a traditional PSU, it's reasonable to ask which PC cases are going to be compatible with RMx SHIFT PSUs. We've got that all sorted out for you.

Just click the "CHECK CASE COMPATIBILITY" button on any RMx Shift product page and type in your case model.
