CORSAIR HX Series HX750 CP-9020137-NA/RF 750 W ATX12V v2.4 / EPS12V 2.92 80 PLUS. Platinum efficiency, fully modular and virtually silent. CORSAIR HX series power supplies give you extremely tight voltage regulation, quiet operation, Platinum-certified efficiency, and a fully modular cable set. Built with all Japanese 105°C capacitors, they’re a great choice for high performance PCs where reliability is essential. 80+ Platinum: Runs cooler and uses less power than less efficient power supplies. Fully Modular: Allows user to only use the cables they need for a cleaner looking build with better airflow. 135mm FDB fan with Zero RPM mode: Virtually silent operation at low loads. MTBF hours: 100,000 hours. +12V Rail Switch: Gives the user the choice of a single +12V rail or multiple +12V rails. 80 PLUS Platinum efficiency reduces operating cost and excess heat, and Zero RPM fan mode ensures virtual silence at low and medium loads. 100% Japanese 105°C capacitors. Zero RPM Fan Mode. Since the fan doesn’t turn on until it’s needed, you’ll enjoy virtually silent operation at low and medium loads. Power In Your Hands. Toggle single +12V rail or multi +12V rail mode. In the’Single’ position, the full output capability of the power supply’s +12V rail is available to any and all connectors, while in the’Multiple’ position, each individual connector has Over-Current Protection so no more than 40A of current can be delivered on any given cable. HX Series ATX Power Supply. 80 PLUS Platinum efficiency, delivering 90% energy efficiency at real world load conditions. ZeroRPM mode for fanless operation at low loads and outstanding noise reduction. 135mm thermally controlled, fluid dynamic bearing fan only spins up as needed. Fully modular cables for easy installation, less clutter, and helps maximize airflow through your computer’s chassis. Over-voltage protection, under-voltage protection, short circuit protection, over power protection, and over temperature protection provide maximum safety to your critical system components. Safety and Agency Approvals: FCC, ICES, CE, UL / CUL, CSA, C-Tick/RCM, TUV, CB, CU, KC Mark, RoHS, WEEE, RoHS (China), Reach.
