Corsair RM750i power supply review - Introduction

Corsair Professional Series RMi PSU - Silent & Rail Configurable

We review the Corsair RM750i GOLD power supply. This silent RMi series PSU comes Gold certified, that means it's 90% efficient at 50% load. Efficiency matters. The PSU itself is fully modular, for most of you with a side panel window in their chassis a must really as you'll want modular cables. The new PSU also improved on the audibility front and through Corsair LINK software you can even configure the 12V rails in a single and multi rails. This 80 Plus Gold certified power supply has silent Zero-RPM fan operation, Corsair Link customization and monitoring. The product comes with solid capacitors, and fully modular cables. The PSU is cooled with a 140 mm fluid-dynamic-bearing fan that will only spin up when the PSU needs to and operating virtually silently at low and medium loads.

This silent RMi 750 comes Gold certified, that means it's 90% efficient at 50% load. Efficiency matters. The PSU itself is even 100% modular, for most of you with a side panel window in their chassis a must really as you'll want modular cables. The PSU also improved on the audibility front. Have a peek at the article. Efficiency matters; years ago PSUs were as low as 70% efficient, meaning that 30% of the used power simply vanishes, whilst you are paying for it on that electricity bill. If your components eat away 500W then with that 70% efficient product you'd actually use 650W. The PSU itself is 100% modular as well, for most of you with a side panel window in their chassis a must really as you'll want modular cables.

As mentioned, the PSU improved on the audibility front as the fan doesn't even spin until it reaches a certain load or temperature, so if your PC is in idle and pretty much doing nothing, the rather silent fan will actually disable itself. That's right, the thermally-controlled fan spins up gradually above 40% load thus up-to 300 Watt power consumption this PSU makes no noise whatsoever, but even during normal use and when gaming it remains silent really.

All in all we have plenty to show you and test. Mind you that being the mainstream to high-end range you'll get an added benefit as well, Corsair Professional Series PSUs are backed by an excellent 7-year warranty. Hey, that's gold all by itself, but sure my man -- have a quick peek and then let's head on-wards into the review.
