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, theyre a great choice for high performance PCs where reliability is essential. 80 PLUS Platinum efficiency reduces operating cost and excess heat, and Zero RPM fan mode ensures virtual silence at low and medium loads. Premium internal components ensure solid power delivery and long term reliability. Toggle single 12V rail or multi 12V rail mode. In the SINGLE position, the full output capability of the power supplys 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. Main Features 80 PLUS Platinum efficiency, delivering 90 energy efficiency at real world load conditions Zero RPM 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 computers chassis Engineered to meet maximum power output at a server-grade 50°C temperature rating 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 Main Features 80 PLUS Platinum efficiency, delivering 90 energy efficiency at real world load conditions Zero RPM 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 computers chassis Engineered to meet maximum power output at a server-grade 50°C temperature rating 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 Interfaces/Ports Power Connectors    1 x UK Plug SATA Connectors    16 PCI Connectors    6 x PCI-E Floppy Connectors    1 x Floppy Connector Other Connectors    1 x ATX Connector • 2 x EPS Connector • 6 x Four Pin Connector • Compliance Standards    FCC • ICES • CE • UL / CUL • CSA • C-Tick/RCM • TUV • CB • CU • KC Mark • RoHS • WEEE • RoHS (China) • REACH Electrical Voltage    100 to 240 V AC Power    850 W Power Cord    UK Power Cord Physical Form Factor    Power Supply Unit Case Colour    Black Pack Quantity    1 In The Box    HX Series ATX Power Supply • Power cord • Mounting screws • Cable ties • Corsair case badge • User manual Width    15 cm Depth    18 cm Height    8.6 cm Weight    1.92 kg Warranty Warranty    Ten Years Warranty Key Features Modular Cables    Modular 80Plus Rated    80 Plus Platinum PSU Form Factor    ATX Molex connectors    8 PCI-E Connectors    8 Floppy Connector    1 Motherboard Power Connectors    4 4-Pin x 2 PCI-E Pin Type    6 2-Pin PSU Depth    180 mm ETA Efficiency Cert.    A Lambda Noise Cert.    A
