The RM750i comes with all available protection features, and besides full definitive, it uses the same FDB fan as the other high-end Corsair units. Thanks to its quality bearing, the NR135P fan should last for ages. On top of that, it is very quiet, even at higher speeds. Moreover, it is supported by a highly relaxed fan profile and a semi-passive mode.

Distribution Of Power

he same OCP trigger point applies to the 24-pin ATX connectors, and all six-pin modular connectors are fed by a virtual plus 12V rail with 40A OCP as well. According to Corsair, when the PSU operates in multi-+12V mode, which is selected by default, the over-current protection (OCP) is set to 40A on each one of the eight-pin modular connectors for PCIe and EPS cables. n other words, power distribution is optimal since the PCIe and EPS cables are fed by dedicated plus 12V rails. The same applies to the 24-pin ATX connector.

Exterior Side

There is also a sticker letting you know that the fan will not spin at light and moderate loads. This notification is mostly for folks who might be inclined to think the fan defective once they notice it not spinning. On the PSU’s sides, decals show the model number of unit. Finally, the power specification label can be found on the bottom.


We hope that this will power supply be better for PC users.
