Available in wattage outputs from 550w all the way up to 1000w, we have in our possession for this review the ‘top-dog’ 1000-watt model. Coming as a fully-modular design and 80-Plus Gold efficiency rating, this already has all the hallmarks of a great power supply suitable for practically any high-specification gaming or professional PC. With Corsair placing a high-emphasis on low noise output as well, the RM1000X really does appear to be ticking all of the right boxes!
