Pulled out of the protective bubble wrap, we can get a little closer to the Tarantula. The main ATX power cord assembly exits on the left front while the modular connection exits on the right hand side. The modular design of the Tarantula differs from the traditional modular power supply that has the connections built into the case. The Bgears unit has the connections point just outside of the case with the wiring stubbed out roughly three inches.
The Tarantula uses a 135mm fan on the bottom of the power supply enclosure to push a large volume of air through the enclosure to provide adequate cooling. The specifications of the Tarantula are listed on the case to provide a quick reference when the information is needed.
The Tarantula is adequately vented to keep the enclosed components cool. Most of the air is directed out the back of the housing via a honeycombed grill.
One thing you should never do is to open up your power supply. Several concerns are raised; first and foremost is safety and second is the warranty of the power supply. Just so you don't have to open this power supply up to determine the components, I will open her up. On first inspection, the unit features a large heatsink to effectively deal with the heat generated. The 135mm fan plays a huge role in keeping the components cool. The fan appears to be made or distributed by young lin tech. Looking at the power supply's heatsink, it was very similar to the Ultra 600 watt power supply used as a comparison for this review.
The primary and secondary sides of the Tarantula are viewed in detail here. The Tarantula uses a large Teapo filter capacitor rated to 85 degrees Celsius 420v 330µF.
