Conclusion

With the RM650, Corsair has an overall solid power supply in its portfolio, which is able to score with its low noise level as well as the integration into Corsair's Link software. Other than that there is a fully modular cable management, there are plenty of connector cables and the unit easily hit 80 Plus Gold standard. Furthermore noise and ripple are very good. What could be improved is the soldering quality, especially on the bottom side of the PCB.

Although the RM650 is a good PSU, there are is one crucial point we have to address, which has to do with competition from Corsair's own camp. First of all some background information: the RM650 is based on the same design like the RM550 and the RM450, which means that the RM650 is the highest upgrade level of this layout. If we now have a look at the RM750, then we see, that components received improved cooling, which means lower operating temperatures for the components and ultimately increased reliability through better cooling. If we would build a PC that burns up to 600 Watt, then we would happily spend 10 US-Dollar more for the RM750 and get a unit with even better internal cooling.

Last but not least we headed over to Geizhals.at and checked what the competition has to offer in the same price range. What we found is a Seasonic X-650, which is one of the best 80 Plus Gold certified power supplies out there and it also offers an excellent noise level.

The RM650 receives good 4 out of 5 stars.
