Its fully modular design and ease of installation are also frequently praised, simplifying cable management and the overall building process. While some users noted its larger size, the positive feedback overwhelmingly focuses on its reliability and value. The power supply is considered a great option for its price point.

    Quiet, has zero db fan mode. Only downside is Corsair has changed the amount of included PCIE power cables from 3 to 2. Extra cables are almost impossible to find through retail channels

    Bulky, but mostly the fault is on me for not having measured parts before buying. Power supply itself works great.
