Specifications:
This power supply has a continuous wattage of 950 which is enough power for most average computer systems.
Now how is this wattage determined? Well to understand this, you need to know what rails are. Rails are basically well regulated transformers which convert domestic current into the voltages that your computer system can use. There are essentially two different rails: the +3.3/+5v rail and the +12v rail. In this particular case, the approximate maximum peak output of the +3.3/+5v rail is 170 watts and the +12v is 810 watts, which is essentially how the wattage of this power supply is determined.
The 3.3/5v rail is responsible for the motherboard, memory, PCI cards and so on. While the 12v rail is responsible for the hard drives, optical drives, fans, CPU, Video Cards, etc.
Ok, let's get into the details and specifications!
Here are the peak amps on each rail: The +3.3V is 24A, and the +5V is 30A. Many quality power supplies have multiple +12V rails, this one has four and they are all 20A each. Please note that a single +12V rail is best if you are running a multiple Video Card configuration (SLI/Crossfire). Also, the AC input specs are: 110~230VAC, 50-60Hz.
This power supply meets the ATX 12V v2.1/2.2 specification. For additional information on form factors please visit Form Factor website. It also meets the newest SSI standard, EPS12V standard . For additional information on SSI, visit the Server System Infrastructure site. Having the latest ATX 12V specification is important because some power supplies tend to overheat and shut down the system under max load. Higher end power supplies float in the 85% range. This PSU is above 80% efficient. The efficiency of any PSU will vary depending on load. For detailed efficiency refer to the below diagram. Note that the more efficient a power supply is, the less heat will be generated, and therefore it won't require excessive cooling.
Chroma, ATE (Automatic Test Equipment) & Burn-in function tested. So what the heck does all that mean? Well, production Hi-pot testing ensures insulation integrity. Chroma is a world recognized leader in power supply testing equipment which includes automated power supply test systems, electronic loads, programmable AC power supplies, and related equipment to support the power conversion industry. Finally, Burn-in is really a stress test and means it was tested at full load and still meets specs.
A power supply also needs to be fail-safe and worry free. This unit has that covered with Over Current/Voltage/Power Protection, Under Voltage Protection, and Short Circuit Protection provide maximum safety to your critical system components.
Most new power supplies are also RoHS certified, which this one is. RoHS stands for Restriction of Hazardous Substances Directive. "It was adopted in February 2003 by the European Union. The RoHS directive took effect on July 1, 2006, but is not a law; it is simply a directive. This directive restricts the use of six hazardous materials in the manufacture of various types of electronic and electrical equipment. It is closely linked with the Waste Electrical and Electronic Equipment Directive (WEEE) 2002/96/EC which sets collection, recycling and recovery targets for electrical goods and is part of a legislative initiative to solve the problem of huge amounts of toxic e-waste." source
I should also mention that this PSU uses Japanese Capacitors which results in cleaner more reliable power than cheap capacitors found in many other PSUs on the market.
Ever wonder who actually makes a particular PSU? Most companies do not make their Power Supplies in house. Rather, they are made by an original equipment manufacturers (OEMs) which are probably unknown to most of us. This is not the case with this PSU. So, how does one go about finding out who actually made it? Well, that's very simple. Just get the number which is below the UL logo. In this case it's E316120 Now visit this UL Database site and enter the number.
This power supply also comes with a 3 year warranty. Most PSU companies only offer a 1-3 year warranty, so this is on par, but some come with a 5 year warranty. Generally most everyone will have a power supply for a a few years so it’s great to know you are covered.
