This particular product is available in one model, PURE POWER-600AP (Part No.: W0083RU). This power supply has a continuous wattage of 600 which is ample power for today's 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 425 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, AGP card and so on. The 12v rail is responsible for the HDD's, DVD, CD-ROM, fans, etc.

Ok, let's get into the details and specifications!

Here are the peak amps on each rail. The +3.3V is 30A, and the +5V is 28A. Unlike most power supplies with only one +12V rail, this product has three. The +12V1 is 14A, +12V2 is 23A and the +12V3 is 15A. Also, the AC input specs are: 115VAC/230VAC, 50~60Hz, 10A.

This power supply meets the SSI EPS ATX 12V v2.1/2.2 specification. For additional information on form factors please visit Form Factor website. This basically means that a power supply must be able to sustain full load in 50 C (122 F) ambient conditions. Although, power output on all models will decrease ~1 C starting at an ambient temperature of 40 C. Having the ATX 12V v2.01/2.02 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 80% efficient. Note that the more efficient a power supply is, the less heat will be generated, and therefore it won't require excessive cooling.



This power supply also has Active Power Factor Correction (PFC). Active PFC is preferred over Passive PFC because it provides a more efficient power frequency. This reduces total harmonics, corrects input voltage, and it allows for a full input voltage range. The disadvantage is that it increases the cost of the power supply. This PSU has a 0.99 Active Power Factor value.

Additionally, this product is 100% Hi-pot, 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. This unit has Over Voltage Protection (OVP), Under Voltage Protection (OVP), Short Circuit Protection (SCP), Over Load Protection (OLP), and Over Temperature Protection (OTP).

Also, it's Safety/EMI Approved: CB, CE, FCC, UL, CUL, and TUV certifications.

Ever wonder who actually makes a particular PSU? Most companies like Tt do not make the Power Supplies in-house. Rather, they are made by an original equipment manufacturer (OEM) which are probably unknown to most of us. 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 E144195. Now visit this UL Database site and enter the number.
