Over the past several years, Corsair is a name that we've grown to love for a vast number of reasons. They take great pride in their power supplies from low to high-end. Their units are always spectacular inside and out and the results that we see are some of the best in the industry. They were the first to the market with a full digital desktop power supply and since their introduction, they have been working to integrate their digital monitoring and control technology into all of their units.
Today, we have the new RMi series power supply on the bench. The RMi series is Corsair's entry-level enthusiast power supply with a focus on quality outputs and minimal noise. Our unit today is the RM750i which is the 750W model, but it is also available in 650W, 850W, and 1000W models as well. The RMi series shares several similarities with the RM series in that they are both analog units, feature 80 PLUS Gold efficiency, and run fanless up to 40% load.
The RMi series picks up a few new features though such as all Japanese capacitors, Corsair Link capabilities, and a longer warranty to name a few. Let's start tearing this apart to see what all it offers.
Specifications, Availability and Pricing
The Corsair RM750i 750W power supply features a single 12V rail that is rated for 62.5A or 750W of power. The 3.3V and 5V rails are rated for 25A each with a combined maximum output of 150W. The 5VSB rail is rate for 3A or 15W. The combined maximum output for the Corsair RM750i is 750W.
Being that this is a Corsair unit, we would expect nothing less than a complete set of features out of the RM750i. This holds even truer since it is one of their enthusiast grade units. As you can see, the RM750i doesn't miss a beat on our feature summary. It has a complete set of protections including SCP, OVP, OCP, OPP, and OTP. The unit features a fully modular cable design, all of which are either fully sleeved or of the flat ribbon type. The power supply is rated for 80 PLUS Gold efficiency and for 100% continuous output at 50C. It is nice to see the bump up here in power rating as the previous RM series units were only rated for 40C.
Corsair has an MSRP of $139.99 on the RM750i. Considering what you get with the unit, this seems like quite a bargain. There may be cheaper units of the same wattage on the market, but there will be less than a handful that provide similar features AND build quality for the same price. Corsair backs the RM750i with a seven-year warranty.
