750W Power supply unit category is especially popular, hitting a sweet spot of ample headroom and affordable pricing for high-end hardware. A roughly 15 dB(A) noise output makes the RM750x one of the quietest 750W PSUs available.
Corsair's suite of protection features is complete, aside from OCP on the +12V rail, which is replaced by over-power protection on single-rail PSUs. Active cooling is handled by a 135mm fan with a rifle bearing.
