The B12 BC Series is available in the standard ATX Form Factor and in wattages that are most common for a PC system. The Seasonic B12 BC achieves 80 PLUS® Bronze standard of providing at least 82 %, 85 % and 82 % power usage efficiency at 20 %, 50 % and 100 % operating loads, respectively. This efficiency, combined with Active Power Factor Correction, enables the B12 BC series power supplies to lessen energy waste, which translates into savings on the costs of energy costs for its users. In addition to being greatly efficient, the B12 BC units utilize the LLC resonant converter design, and the industry’s leading Smart and Silent Fan Control (S2FC). 80 PLUS BRONZE The 80 PLUS Bronze certification indicates that a high percentage of the electricity is converted into useful power, therefore there is less heat lost and more money saved on the electricity bill. The 80 PLUS Bronze certification guarantees greater than 82 %, 85 % and 82 % efficiency at 20 %, 50 % and 100% operating loads, respectively. Seasonic’s B12 BC Series is an economical choice with great performance and high built-in value.SpecificationsCoolingFan diameter: 12 cmNumber of fans: 1 fan(s)Fan location: TopCooling type: ActivePerformanceOn/off switch: YesPower supply unit (PSU) form factor: ATX80 PLUS certification: 80 PLUS BronzePurpose: PCMean time between failures (MTBF): 100000 hCertification: cTUVus, TUV, CB, CCC, BSMI, CE, FCCBearing technology: SleeveDesign80 PLUS certification: 80 PLUS BronzeCertification: cTUVus, TUV, CB, CCC, BSMI, CE, FCCProduct colour: BlackCooling type: ActivePowerTotal power: 850 WAC input voltage: 100 - 240 VAC input frequency: 50/60 HzInput current: 10 ACombined power (+3.3V): 100 WCombined power (+12V): 840 WCombined power (+5V): 100 WCombined power (-12V): 3.6 WCombined power (+5Vsb): 12.5 WMax output current (+3.3V): 15 AMax output current (+12V): 70 AMax output current (+5V): 15 AMax output current (-12V): 0.3 AMax output current (+5Vsb): 2.5 APower protection features: Over current, Over power, Over voltage, Short circuitPorts & interfacesMotherboard power cable length: 55 cmCPU power cable length: 60 cmMotherboard power connector: 20+4 pin ATXNumber of SATA power connectors: 6Peripheral (Molex) power connectors (4-pin): 3PCI Express power connectors (6+2 pin): 4CPU power connector (4+4 pin): YesPCI Express connector: YesATX power connector (20+4 pin): YesCabling type: Non-ModularEPS power connector (4+4 pin): YesOperational conditionsOperating temperature (T-T): 0 - 50 °CWeight & dimensionsWidth: 150 mmDepth: 140 mmHeight: 86 mmTechnical detailsSustainability certificates: CE, ENERGY STAR, REACH, RoHS, WEEECertificates80 PLUS certification: 80 PLUS BronzeCertification: cTUVus, TUV, CB, CCC, BSMI, CE, FCC
