Most users nowadays look for good performance along with a very silent operation, which is a really hard find in, especially, high-capacity PSUs. Corsair’s response to the scarcity of silent units was the RM series which currently includes six members with capacities ranging from 450 W to 1000 W. We have already tested three RM units 650, 750, and 850 W models which satisfied us with their performance and generally silent operation, although the 750 W and 850 W models had the cooling fan engage rather late, which increased internal temperatures. We already tested most RM units, so why don’t test and the strongest one, Corsair obviously thought, so they sent us the RM1000 which, as its model number implies, has a capacity of 1 kW.The RM1000 is Gold certified and has a fully modular cabling design, two features common to all RM units. Corsair also says it to be optimized for silence as its high efficiency and low-noise capacitors and transformers will eliminate coil-whine issues, a problem many modern high-performance platforms suffer from. Its fan also operates semi-passively and Corsair promises this PSU to be whisper-quiet even while being pushed hard. We will soon find out whether this holds true since we plan to push it beyond its limits during our evaluation tests. The RM1000 utilizes a single and powerful +12V rail and is currently prices very affordably for a PSU of its category, so it will easily do well in our price/performance ratio chart if it does well in our performance tests.
