Corsair are back once again with yet another flagship chassis product; the Graphite 780T. Their latest chassis is a premium grade full-tower, set to be the new king of their popular Graphite series which already has several award-winning chassis products in its range, such as the popular 600T.
We first saw this chassis at Computex 2014 earlier this year, not that we could miss it given that this chassis is certainly on the larger side. Our initial impression of the case were good, it looked stunning and packed full of features, but this week is the first time we’ve been able to get properly hands on with it and take a good long look at what it has to offer. At £150 the 780T isn’t cheap, so there’s no doubt that this is for the high-end user/enthusiast market. This means it needs to offer some pretty impressive features, build quality and a whole lot more to justify the wallet busting price tag.
As you can see from the specifications below this chassis is incredibly capable, with support for everything from tiny Mini-ITX motherboards right up to E-ATX, so even workstation motherboards will be right at home here. There is an abundance of storage bays, as well as extra dedicated 2.5″ bays, room for four radiators ranging in size from 120mm right up to 360mm, as well as plenty of room for taller CPU coolers. There are 9 expansion slots that’ll be ideal for multi-GPU configurations and with 355mm GPU support, you’ll have no trouble getting even the largest cards on the market into this chassis.
The packaging is pretty straight forward, with a mock-up of the chassis on the front.
Around the back you’ll find a breakdown image detailing all of the major components and the chassis specifications are on the side of the box (see above).
In the box you’ll find the chassis, which comes with protective film on the side panel, around the front panel and protective tape to hold the dust filter covers in place while in transit.
In the box you’ll also find a smaller package with all the major fitting screws and a few cable ties.
The left side of the chassis features a huge lift-out side panel with a flip-up locking handle at the top. There is an extremely large window with a slight tint that gives you a great view of the chassis interior.
The right side panel is the same general design as the left, with a solid metal panel in place of the window.
The front panel is finished in mostly matte black plastics, and is also slightly recessed into the white frame around it. There are two 5.25″ drive bays at the top with a large ventilated panel below them.
The panel is easily removed via two push-clips at the top; this panel acts as a dust filter and is fully washable. Behind the cover you’ll find loads of mounting options; 2 x 140mm or 3 x 120mm fans, as well as support for 280/360mm radiators. There are two high quality 140mm LED fans pre-installed.
Above the 5.25″ drive bays, you’ll find a small LED lighting strip that lights up when the system is powered on.
Around the back you’ll find some extra ventilation near the top, a universal fan mount, the motherboard I/O, 9 expansion slots, two routing holes with pop-out metal covers and the PSU mounting area.
The universal mount features elongated screw holes and can mount 1 x 120mm or 1 x 140mm fans or radiators. A high quality 140mm fan has already been pre-installed.
The top panel features another clip-in dust filter that runs the complete length of the chassis.
Behind the cover you’ll find a vast amount of room for fans and radiators, with support for 3 x 120mm or 2 x 140mm fans, as well as 280mm and 360mm radiators. Rubber washers are pre-applied to the 120mm fittings; these will help dampen vibrations from any fans you choose to install.
The front I/O panel is nicely designed and features a three speed fan controller, two USB 2.0 ports, two USB 3.0 ports, HD Audio jacks and the reset button. Towards the front you’ll also find a very cool start/stop button for the master power control.
On the base you’ll find a two huge feet that run the length of the chassis, each featuring two thick rubber pads to prevent the chassis from slipping around on your desk or floor.
There are two dust filters on the base of the chassis. One slides out from the back, and the other from the front. Each filter is washable for easy maintenance and they help provide clean airflow to the PSU area and any bottom mounted cooling.
The chassis interior is vast, with everything finished off in a slick black paint job to give it a nice uniformed look. The back plate features a huge cut-out behind the motherboard which will help when mounting or changing a CPU cooler, and there are five large cut-outs with rubber grommets to aid with cable management.
There are two fully removable hard drive bays in the front, each with support for three 3.5″ or 2.5″ drives.
The base of the chassis has a considerable amount of space available, that will hold even the largest consumer PSUs on the market. There is also a large cut-out for routing all of your power cables, space for extra fans and radiators. Large radiators will require you to remove the hard drive bays, although you can still use the dedicated 2.5″ bays, or suspend the 3.5″ bays from the bottom of the 5.25″ bays.
Each of the expansion slots come fitted with a reusable ventilated cover, each held in place with a quick release thumb screw.
The rear 140mm fan has plenty of room above and below it, perfect for AIO water coolers which feature a built in reservoir.
The two 5.25″ drive bays come equipped with a simple tool free locking mechanism.
Around the back you’ll find an extensive space for routing cables, as well as a bunch of cable tie loops to help keep things neat and tidy.
There is a deep recess at the bottom, perfect for tucking away even more cables, and very handy for those who have a non-modular PSU.
There are three dedicated 2.5″ drive bays around the back and a cut-away on the back plate allows you to see the drives displayed from the left side panel window. These bays also completely removable should you need to; something that will no doubt please chassis modders.
Total build time on the 780T was just under 30 minutes; a nice, quick build for a chassis of this size and that is mostly thanks to the extensive amount of work space on the interior. All components fit with ease first time and the addition of pre-installed motherboard standoffs and extensive cable routing space certainly helped.
The 780T is a super wide chassis, as you can see here by just how slim our Sapphire R9 270X Toxic looks inside, almost another full GPU width between the edge of the card and the side panel window. The cable routing on this chassis is fantastic and you can see here that there are no unnecessary cable obstructions around our major components, which should prove beneficial to airflow.
Our standard ATX PSU looks tiny in this chassis. There is loads of room for something bigger and the large cut-out next to it makes it easy to pass cables through to the back of the chassis; although I would prefer two smaller cut-outs with rubber grommets to keep things looking more uniform.
The front hard drive bays are tool-free for 3.5″ drives, so installation was nice and easy.
The 2.5″ drive bays are also tool free; just slide the drive into the clip and connect the cables. I really like these bays as you can clearly see the drive from the left side of the chassis; a nice feature for those who love showing off their components.
The Corsair H100i fits into the top section with ease and the over hanging top edge of the chassis means that it’s hidden just out of sight. There is still loads of room here too, which is good news for those wishing to install a push-pull fan configuration.
Side panel back in place and we’re treated to a clear view of the system interior. The cable routing on this chassis is a big win as any imperfections in the build will be easy to spot through this side panel window.
The Corsair Graphite 780T is available for pre-order from Overclockers.co.uk for £139.99 fo the black model, while the Yellow and White models are a little more at £144.95 each. The price is around the same as similar specification offerings from Cooler Master and NZXT, so while it is expensive, it is still competitive.
Corsair have really pushed the limits with the 780T; this chassis is absolutely gargantuan! Sure, it’s not quite as big as their revolutionary 900D Obsidian chassis but compared to your average full-tower, the 780T certainly stands out from the crowd in a very good way. Its bulky design does have some benefits, as there is an extensive amount of space on the interior for your components, a huge area for cable routing and plenty of elbow room to get in there and work on your system. The biggest graphics cards on the market will fit in here with ease, as will large power supplies and any other ultra high-end components that the enthusiast market love to play around with.
Those interested in water cooling will love the 780T. There’s space for up to four radiators and should you strip out the front hard drive bays, you can even manage two 360mm radiators, while still holding a 240mm in the bottom and a 140mm in the back. Air cooling is impressive too, with three high quality 140mm fans pre-installed, but extensive support for additional 120mm and 140mm throughout the chassis. Both air and water cooling can also reap the benefits of the large dust filtering panels on the top and front, as well as the two high quality slide-out dust filters on the base of the chassis. The included fan controller is another welcome bonus for cooling and while it’s not as advanced as most after market controllers, it’s more than enough for handing a few chassis fans.
Modular storage is a welcome feature for those who love to customise their builds. All of the storage bays are fully removable and very easy to work with; allowing you to free up more room for other components. The front drive bays do need to be removed to make room for front mounted radiators, but will also free up room for other additions such as pumps and reservoirs.
The chassis is rather unique in terms of design. Sure there is a lot of plastic on show, but it has been colour matched to the metal panels very well and the whole chassis has an uncompromising premium look and feel throughout. The aesthetics may be a little over the top for some, but I personally think that it looks superb. The side panels are another nice touch as they’re really easy to remove and lock firmly back into place with little effort; I personally find myself needing to access the interior of my rig on a weekly basis, so having a tool free side panel is a real time saver.
