Diving Deep into the DirectCu IIís Features

Like many other manufacturers, ASUS utilizes a long list of features that should not only extend the life of certain cards but may also prove beneficial for overclockers. While we have already detailed the benefits derived from the DirectCu II heatsink and several other visible items, there are a number of additions to this card which canít be seen. Most fall under the purview of ASUSí SAP or Super Alloy Power design. When used in conjunction with the 8-phase (6 phases for the core and 2 phases for the GDDR5) Digi+ VRM , these higher end components allow for an impressive setup.

The chokes used in the SAP design are supposed to offer cool and quiet operation without any of the coil whine thatís normally associated with some graphics card designs. The coil itself is wrapped tightly around a core of concrete substrate that acts as a buffer, thus lowering vibrations and efficiently dispersing the heat evenly throughout the chokeís structure.

The Super Alloy Capacitors may sound like nothing more than a fancy marketing term thatís meant to draw in naÔve first time buyers but there are some actual benefits to the components which ASUS has chosen. Not only do these capacitors boast a lifespan thatís 2.5X longer than standard units but they also factor heavily into the long term stability of an ASUS graphics card.

Typically, the MOSFETs on graphics cards, motherboards and many other high end PC components are relatively large and produce quite a bit of heat. This is why theyíre usually covered by extensive heatsinks but the ones used by ASUS buck this trend. Their components are crammed into an amazingly small package thatís efficient and thus produces very little excess heat. These ďSuper Alloy MOSĒ units also allow for a 30% higher voltage threshold, thus increasing overclocking capabilities in some instances.

Alongside all of these components, the all-digital Digi+ VRM results in lower power noise and could in extreme instances, improve overclocking results. We doubt most end-users would ever encounter a situation where these components will be put to their fullest use but no matter how you use your card, theyíre still good to have around.

We all know that dust is a constant problem within a computer case and it can shorten the life of certain components like fans and power supplies. ASUS has implemented what they call a ďdust proof fanĒ which is basically a hub design that ensures dust does not enter the bearing area which will in turn extend the fanís lifespan. With this feature it is claimed that the fanís life will be extended by nearly 10,000 hours.
