FX-777A-ZDSC Detailed Features

The connectors are the same available on the larger cards: two mini-DisplayPort, one HDMI, and one (bright red) DVI. Using accessory cables from XDX you can connect up to six monitors to this card.

The Cape Verde GPU puts out much less heat than Tahiti GPUs, so the elaborate vapor-chamber and heat pipe-based cooler of the 79XX series cards isn't necessary. The heat sink is a simple copper plate with aluminum fins, cooled by two fans..

The top of the board has a anodized red aluminum panel with the card's model number and "Ghost Thermal Technology" on it. This is obviously a plus for those of you with windowed cases.

Removing the cooler exposes the Cape Verde GPU and four Hynix memory chips that comprise the card's 1GB of memory. As is all too common these days, far too much thermal paste was applied to the GPU when the card was assembled. The memory chips do not touch any part of the cooler and rely on airflow from the dual fans for cooling.

The front of the card is open, so about half the cooling air will exit into your case rather than out the rear of the card. However, this shouldn't be a problem for well ventilated cases since this card uses relatively little power and thus produces relatively little heat.
