All the way at the backside you'll spot a series of LEDs and three buttons, here you can actually regulate the fans in 10% steps. We're not really sure what to make of it to be honest. Preferably you do all this stuff from your tweak utility as you do not want to touch the PCB/ graphics card all the time. Also (typically) in software you can program a temperature delta, e.g. low RPM when the GPU is cold and high RPM after say 70 Degrees C. That stuff you can not do with a button. It's a funny feature to see implemented though.
Here's a perspective view taken from the topside. Two fans and as stated that logo at the top is the multicolored MATRIX LED load indicator, color changing visual display of the real-time GPU load. But let's zoom in a little at the power connectors.
Correct, you'll need two 8-pin power headers, preferably leading from the PSU directly, to power up this puppy. These two connectors alone can provide 300 Watt and another 75 through the PCIe slot.
ASUS GTX 580 Matrix Platinum review We received that big'ass Republic of Gamers (ROG) MATRIX GTX 580 graphics card from ASUS. The Republic of Gamers MATRIX GTX 580 Platinum graphics card is powered by an extensive 19-phase VRM circuitry that draws power from two 8-pin PCI-Express power connectors. The card will come with two BIOSes, so should you mess one up you have a failsafe by pressing a button. Something interesting is on-the-fly fan RPM control, check the photo's later on for that feature.
ASUS GTX580 DirectCU II SLI review We review the GTX 580 DirectCU-II and it is one big momma ! ASUS shortly ago released a new version in the flagship series of NVIDIA graphics card, the GeForce GTX 580. They customized the graphics card itself, overclocked it, allow even more tweaking and to top it off, they placed a three slot wide cooling solution on it. heck let's test two of these in an SLI setup.
ASUS GTX560 DirectCU II review The ASUS GTX560 DirectCU II or SKU name ENGTX560 TI-DCII tested today indeed comes all customized and factory overclocked, with quality grade components and a robust build the dark PCB of the GTX560 DirectCU II will carry a GPU clocked at 900 MHz and memory at 4200 MHz, both thus a nice chunk faster than reference.
