The studio has accumulated numerous video cards from AMD and NVIDIA. There are several desktop machines which eventually are planned to be rack mounted chassis so that they can be streamed via remote desktop.

The Zotac 8600 GT was destroyed by 196.75 with the fan profile set at 30% regardless of GPU temperature. Armies of cards were destroyed. NVIDIA had to pay out $200 million for laptop failures while desktop users had to fend for themselves.

The trend away from 6-pin PCIe power and more towards the 8-pin PCIe power is driven mostly to simplify cable provisioning. 8-pin cables can afford over 150W to eliminate motherboard power needs.

Gaming enthusiast cards have long exceeded 100W of power required and while the 75W PCIe slot power is available, it is woefully inadequate. PCI Express power cables have been the solution that has grown over time. Single rail 850W power supplies are now common which can handle dual graphics cards. The HX1000i simply is capable of even extreme video cards.

Many cards like the HD 6970, GTX 690 and R9 Fury are 300W class cards which require dual 8-pin cables to be able to provide them with adequate current. The HD 7990 is so demanding it requires three 8-pin cables.
