As demands for smaller systems have risen people have struggled to find power supply units from brands and series they trust in the SFX category. Though it didn't come as soon as we originally planned Cooler Master is glad to finally be able to provide a reliable high quality PSU that's compatible with smaller cases and their accompanying components. A reduction in size should never mean a reduction in quality and with the V SFX Gold it doesn't. Make it mini. Make It Yours.80 PLUS GOLD EFFICIENCYThe efficiency of your power supply unit is important because it directly affects your system's performance and your power bill. The efficiency rating does not reflect the quality or reliability of a PSU. It only reflects the unit's ability to move power from the wall to your components. The higher a PSU's efficiency is the lower the total amount of power it needs to power your system. The V SFX Gold series has an 80 PLUS Gold efficiency rating meaning it has a guaranteed typical efficiency of 90%. SFX-TO-ATX BRACKETThough the V SFX Gold was made for mini-ITX builds it can actually be used for any ATX case as well. With the included SFX-to-ATX bracket you can instantly convert this unit from an SFX to an ATX PSU. That makes this product Cooler Master's first power supply unit that can be used to power systems ranging from as small as mini-ITX all the way up to E-ATX motherboards. Cooler Master's motto is "Make It Yours" and with the V SFX Gold's almost universal case compatibility you can use this PSU to build just about any system you'd like.QUIET COOLINGTwo of the main benefits of a mini-ITX build are the reduced size requirements and reduced noise. The main cause of noise in a PSU is usually the fan. The V SFX Gold uses a 92mm FDB fan so it's extremely quiet. With its small size high efficiency and excellent heat dissipation the overall noise is kept to an absolute minimum.FULL-MODULAR CABLINGA mini-ITX case means minimal space for everything. Not only does that mean a reduction in room for the power supply unit but also for the accompanying cables. That's why the V SFX Gold offers full-modular cabling. Use the absolute bare minimum in space for cable management by using the absolute bare minimum in cables. Connect only the ones you need for your system to preserve as much room as possible leading to both improved airflow and better presentation.10 YEAR WARRANTYThe V SFX Gold series offers top quality power supply units that can and will deliver professional grade performance at normal use wattage levels. Just because the size of the PSU is reduced doesn't mean the quality should be. And with this unit you can rest assured that it hasn't. You can trust this PSU for all your computing needs whether it's casual work or hefty continuous gaming sessions. Just in case you arent sure all V SFX Gold series models come with a 10 year warranty.ModelMPY-8501-SFHAGVATX VersionSFX 12V Ver. 3.42PFCActive PFCInput Voltage90-264VInput Current10-6AInput Frequency47-63HzWattage850WFan Size92mmFan BearingFDBEfficiency90% @ Typical LoadRating80 PLUS GoldERP 2014 LOT 3YesOperating Temperature0-50CPower Good Signal100 - 500 msHold Up Time16msMTBF>100000 HoursProtectionOVP OPP SCP OCP UVP OTP Surge and Inrush ProtectionRegulatoryTUV cTUVus CE BSMI FCC CCC EAC RCM KCC CBConnections1 x ATX 24-Pin1 x EPS 4+4 Pin1 x EPS 8-Pin8 x SATA4 x Peripheral 4-Pin4 x PCI-E 6+2 PinSeriesV SFX Gold SeriesModularFully ModularDimensions ( L x W x H )100 x 125 x 63.5 mm
