Features:
Visually, the Potency looks very similar to most other non-modular performance power supplies. It's body, including the fan grill, is entirely black. Since it isn't modular and therefore doesn't need any extra depth to accommodate modular plugs, the Potency measures a nice and short 5.5" long (from end to end of the fan basically). If you're someone who's running a smaller case or some M-ATX sized cases, you might be limited to using non-modular power supplies because of depth restrictions.

Opening the power supply up I was slightly surprised to not see the popular ADDA fan choice inside it. Rather, Tuniq has chosen to go with a fairly generic brand fan for the Potency. The cooling fan in question is a sleeve bearing fan manufactured by 'Globe Fan' (Model No.: S1202512L). Some quick research showed me that there really isn't much information around the internet on this fan although I did find a couple of forum discussions where people were discussing it being a very quiet fan (although not the highest CFM). To keep noise levels at a minimum the fan is thermally controlled so it's not working any harder than it needs to. On the back the fan is vented by means of a honeycomb style grill. Being ActivePFC you'll notice the absense of a voltage selection switch back here because the power supply will automatically switch to accept input voltages from 100-240V.

Now let's dive a little deeper into the specifications behind the Potency. Tuniq has chosen to use a dual +12V rail design with each rail being able to deliver up to 25 amps of current. We must favor this style of design for those running high performance components on the 12V rail. Most commonly, new and powerful video cards will be drawing a lot of current which is often too much for a quad +12V rail design which has less amps per rail. Therefore, by reducing the number of rails down to two or one we now have more amperage available per rail. Doing a quick calculation with ohm's law, we can see that although each rail is capable of delivering up to 25A, both rails can not deliver a full 25A at the same time without overpowering the supply. To stick behind their firm beliefs in the performance of this power supply, Tuniq has gotten it Nvidia SLI Certified, saying it can support up to a 9800GX2 card.

In addition to that Nvidia SLI Certified logo on the box, this power supply is also 80PLUS certified. For those unaware of what that means, it means that the power supply will always run at 80% efficiency or higher. In laymans terms; it will waste much less power coming from your wall socket than an 'el-cheapo' no-name power supply would. Using the power more efficiently also means that there will be less wasted energy to turn into heat. Since the fan cooling the Potency is thermal controlled, it should run a lot quieter than cheaper power supplies. To sum that all up: 80PLUS = less wasted energy and quieter operation.

For the safety of you and your computer, full circuit protection is intigrated into the Potency. Really, this is something that any half-decent power supply should have but you still need to be careful with those dirt-cheap brands you can find at your local computer store. Covered in the Potency is over current protection, under voltage protection, over voltage protection, short circuit protection and overload protection.

You might also be curious to know that while I was inside this power supply the design of the heatsinks caught my eye. Most heatsinks are finned and usually quite large to help disapate heat into the fan as fast and efficiently as possible. This not only keeps the power supply running cooler but usually allows the fan in the power supply to not operate as loud or as fast either. The heatsinks in the Potency power supply resemble two aluminum walls - there are no fins on them at all. This makes me curious how it will perform in terms of noise and heat during our testing portion of this review.

All the cables on the Potency are sleeved with a black mesh sleeving and all the ends are black plastic. The connector layouts are as follows:
1 * 20+4Pin Mainboard
2 * PCI Express (1 * 6Pin, 1 * 6+2Pin)
1 * 4Pin Molex Y Cable
4 * 4Pin Molex
1 * 4Pin FDD
4 * SATA
1 * 8Pin EPS12V
1 * 4Pin P412V
