The installation of the Gigabyte GeForce RTX 4080 SUPER WINDFORCE V2 (16 GB) in an Acer Predator Orion 3000 depends on several factors:

## Size and compatibility
- The card is 33 cm long, which fits in most modern PC cases, including the Acer Predator Orion 3000, as these usually offer sufficient space for such cards.

## Power supply
- The card has a power consumption of 320 watts. The Acer Predator Orion 3000 often comes equipped with an 800-watt power supply, which is sufficient for installing the RTX 4080 SUPER. However, the card requires three 8-pin PCIe power connectors, which needs to be checked as the Orion 3000's standard power supply may only have two 8-pin connectors.

## Connectors and slots
- The card requires a PCIe 4.0 x16 slot, which most modern motherboards, including the Acer Predator Orion 3000, offer.

To summarise: It is basically possible to install the card, but it is important to check the power connections and size to make sure everything fits and is compatible.
