Corsair RM650 Power Supply review

The market today seems literally flooded with power supplies from a variety of manufacturers. Corsair however have a very special place in the hearts and minds of the enthusiast user, especially when it comes to their power supply range.

Corsair’s new RM650 supply is set to target the demanding enthusiast user who requires 80 Plus Gold Certification, a pure modular design and ultra low noise levels. On paper it certainly ticks all the right boxes.

First impressions are positive. The quality of the paintwork is high and proves resilient to both fingerprints and careless handling during a system build. The flat, ribbon style modular cables will appease system builders who need to route and hide unsightly wiring out of sight. The cables are all very long as well, ideal for builds within tall full tower designs.

Technically the unit is solid, if unremarkable. Load regulation could have been better, although there are no causes for concern based on our results. Equally so, ripple suppression fell within rated industry tolerance guidelines, although we have seen better results from some high grade competitor products in the last year.

Efficiency is excellent, achieving 80 Plus Gold Certification with flying colours. This high level of efficiency ensures that the large 135mm custom fan never has to work that hard, even under high load.

Most of the time this power supply will be silent and unless you are pushing it to within the last 10% of power draw, it will be basically inaudible. Below 400W and the fan either won’t be spinning or it will be rotating so slowly it would be almost impossible to hear under normal circumstances. If you need load above 550W on a regular basis, then we would recommend you aim higher up the food chain anyway, perhaps at a 750W model.

Right now you can buy the Corsair RM650 from Overclockers UK on a special deal for £89.99 inc vat. At this price and considering the all round package it really does deserve a recommendation.

Pros:

  • very quiet.
  • high quality paintwork.
  • pure modular design.
  • flat cables.
  • 105c capacitors.

Cons:

  • A lot of competition at the price.

Kitguru says: A solid all round unit which delivers high quality power without making a racket.
