At the backside you can spot a thing or two alright, yeah, these would be the two GPU areas. The backside of the card has been covered by a protective back-plate with huge gaps, that is much better for cooling really. The critical hot-spots are all uncovered allowing hot air to vent much better. In the lower middle you will notice a signature, It is Roy Taylor’s autograph along with his title. Why is it there? We have no clue whatsoever.



A Dual BIOS button allows gamers to fool around with BIOS tweaking a little. You will always have a fail-safe BIOS this way. And sure, we like the Devil D button style.


This bit is a little shocking, check that out -- 4 units of 8 pin PCI-E power connectors. That means that the card can take 75W from the PCIe 16x slot plus 4x 150W from the PEGS for a total of 675W power delivery. After that number you'd be overloading the voltage lines. 


Powuuuuurrrr, look at all them cables. So we need to have a small chat here. You need a beefy power supply, the card has a TDP of 550 Watts, but draws that through the four 8-pin PCIe connectors. Here's the golden rule of thumb, your power supply must support two 8-pin PCIe power connectors that are each capable of supplying 15 A of dedicated current. So do not make the mistake of connecting your module power supply 8-pin cables towards the same voltage rail! Make sure each connector is on a separate rail. Some PSUs have one giant massive 12V rail, that's fine as well of course.
