Installation: Motherboard, Graphics Adapters and PSU


The Corsair Graphite Series 780T Full-Tower case can accommodate a full range of motherboards, including mini-ITX, microATX, ATX, E-ATX and XL-ATX.

The 780T case uses pre-installed standoffs to mount the motherboard of your choice. Our full-size ATX mobo (MSI Z77A-GD65) slid perfectly into position as expected. As you can see, there is plenty of room around all three sides to work and extra room for oversize motherboards if needed.

A mini-ITX mobo almost gets lost inside the cavernous 780T… 🙂

Graphics Adapters

The Corsair Graphite Series 780T Full-Tower case is well suited for installing one or more high-end graphics adapters. It provides plenty or real estate for multiple dual-slot cards. Expansion slot covers and installed cards are secured with thumb screws

To see how things would fit up we installed a pair of GeForce GTX Titans into the 780T. As expected, the cards fit securely into the designated openings with room around the cards for airflow or routing water hoses if you choose to go with liquid cooling the GPUs.

Note: The 780T supports graphics cards up to 355mm (14”) long.

Power Supply

The Corsair Graphite Series 780T Full-Tower case is designed to mount a standard, full size ATX power supply in the back lower corner of the chassis. The PSU slides in from inside the case and is held in place with four machine screws at the back.

With a Corsair HXi1000 power supply installed (180mm deep) there is still about 7-1/2” between the front of the PSU and the internal 3.5” HDD cage for routing and managing cables and wiring.
