With a strong and dependable foundation DeepCool is helping build better systems today that meet the expectations of tomorrow.GO FOR GOLDCertified 80 PLUS Gold for generating clean and consistent power while reducing heat waste and noise. The PQ-M Series achieves 90% efficiency at 50% system loads.BUILT SOLIDCarefully constructed throughout with quality components to ensure pristine power output quality. The modular board is hard connected to the circuit platform instead of traditional cables for added rigidity and less signal noise.- Dual EPS12V & Triple PCIe- All 105C Japanese CapacitorsSILENCE IS GOLDENA fine-tuned silent fan curve helps produce a perfect balance between cooling and silence with an additional fan stop option during low temperature conditions. A rear fan control button also allows the option for setting a minimum fan speed when fanless mode is not preferred.- Optimized thermal performance.- Reduced noise levels overall- Longer lasting lifespanBEST OF THE BESTFluid Dynamic Bearing (FDB) fans are considered the best-in-class for operating noise and life expectancy compared to other fan bearing types. The hydrodynamic and fluid-based properties greatly reduce friction and vibration that enables better reliability and quiet operation.TypeATX12V V2.4Product Dimensions ( W x L x H )150 x 140 x 86 mm80 PLUS CertificationsGOLDFan Size120mmFan BearingFDBTopologyActive PFC + Full Bridge SRC LLC + DC to DCCapacitorsFull Japan Electrolytic CapacitorsPower Good Signal100-500msHold Up Time=16ms (90% load)Efficiency=90% Under Typical Load (50% Loading)ProtectionOPP/OVP/SCP/OTP/OCPOperation Temperature0 - 50 C (derating from 100 % to 80 % from 40 C to 50 C)RegulatoryCCC/CE/FCC/TUV-SUD/cTUVus/RCM/EAC/CAN ICES-003(B)/NMB-003(B)/UKCAErp RegulationErP 2013MTBF100000 HoursConnections1 x Main Power Connector 24-Pin (20+4) (x1)2 x EPS 12V Connector 8-Pin (4+4) (x2)3 x PCIE 6+2 Pin (x1)2 x SATA (x4)1 x SATA (x2) & 4-Pin Peripheral (x2)1 x 4-Pin Peripheral (x3)
