There are 6 options for the RM series namely; RM450W, RM550W, RM650W, RM750W, RM860W and RM1000W, each built with a Corsair NR135L fan that features a ZERO RPM Fan mode that only turns on during 40% and above loads. But if you have a Corsair AX/AXi or new the HX series, you have already seen this kind of feature.

All RM power supplies comply with the ATX 12V v22.4 and EPS 2.92 standards and has an Active Power Factor Correction (PFC) with PF value of 0.99. All are also fully compatible with the latest Intel Haswell and Intel Ivy-Bridge E systems, making sure that your system is future proof.

The new super silent and power efficient power supplies are also compatible with Corsair Link for real-time monitoring of fan speed, and power delivery. All the RM Series PSUs come with a 5 year limited warranty and judging from the price Corsair has given them, I’m pretty sure these are the new bang for the buck power supplies and will replace the old TX and HX series.
