Closer Look (The Power Supply):

The Antec Truepower Quattro 1000W with its satin black finish and white racing stripes does its best to mimic a racing car, and we are left with little doubt that it's rated at 1000W. The design is novel, but performance is king, and let's face it, once installed in the majority of PC enclosures, all will be hidden.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

The Antec Truepower Quattro 1000W, unlike most other power supplies in this class, is cooled by a single rear mounted 80mm fan. To cool the power supply efficiently and match the more popular 135-140mm cooling fans usually employed, I suspect the fan speed on the ATQ 1000W is going to have to be ramped up at high power draws, leading to high noise levels, but we will see. IEC mains input and an on/off switch join the fan on the back panel, which means the usual solid front panel of the power supply sports the cooling inlet grill and modular cable connectors along one edge. The cables leaving the power supply are not braided all the way into the power supply, which looks a little untidy. The white stripes are neatly continued across the inlet grill.

 

 

The side panels, one with an extra air inlet and the other carrying a comprehensive specification label.

 

 

The top and bottom panels both with the white stripes and 1000 logo. There is another air inlet on one of the faces, which is quite close to the one shown above on the side panel. There is likely a component in this area that requires a little extra cooling.

 

 

The captive cable/connector set on the left and the full set of modular cables on the right. You'll probably notice the use of plastic collars to hold the black cable braiding in place rather than the more usual and less secure heat shrink sleeving.

 

 

The power supply lid that would, in the majority of power supplies, provide a mounting point for a large 140mm cooling fan.

 

The tightly veined heatsink construction increases its surface area and cooling ability dramatically, which may go some way to explaining the use of a smaller 80mm cooling fan. The cooling fan is manufactured by Adda and carries the model number AD0812UB-A70GL, rated at 12VDC 0.30A.

 

The printed circuit board appears very well built, with component and heatsink orientation designed to follow the airflow and maximize cooling. No manufacturer's marks are visible on the printed circuit board, so I don't know whether this board is made for or by Antec. The electrolytic capacitors are all rated at 105°C and, from what I was able to see, made by Nippon Chemicon and Teapo – both reputable manufacturers.

 

 

There is certainly a lot packed into this power supply, which can result in cooling problems. However, with very large heatsinks with a large surface area taking up all the available spare space, cooling should not prove a problem with the Antec Truepower Quattro 1000W. At least if the efficiency is, as stated, at 80 Plus levels. The overall quality of the build looks to be very high and everything is well laid out and tidy.
