Inside the Corsair Obsidian 900D Super Tower

Corsair Obsidian 900D Super Tower Internal Features

Taking the side panel off of the Corsair Obsidian 900D reveals just how much room is inside the chassis. Between expansion slot covers and the drive cage there is enough room for a 17″ long graphics cards! Hopefully we don’t start seen cards that long. Corsair has put a lot of cut outs for cable management in to the motherboard tray. Depending on the size of the motherboard installed into the 900D, it will determine which set of cut outs will work best. Corsair has the motherboard tray cut out for access to the back of the CPU socket.

The back of the Corsair Obsidian 900D chassis features a single 140mm exhaust fan. The 140mm exhaust fan carries part number A1425L12S and is rated for 54 CFM at 1000 rpm.

Taking a quick look at the inside top of the Corsair Obsidian 900D Super Tower, there is plenty of ventilation up there! Enough space for four 120mm fans or three 140mm fans. There is also enough room to throw in a quad 120mm radiator or, you guessed it a triple 140mm radiator.

The 900D will support four 5.25″ optical drives. The top spot is reserved for the front panel as well as the potential radiator.

Out of the box the Corsair Obsidian 900D will support only 9 hard drives or SSD’s. If nine drives isn’t enough for you, you will be able to purchase additional drive cages directly from Corsair.

Behind the bottom door of the Corsair Obsidian 900D we can find an additional six HDD/SSD bays. The one on the left is has the SATA cables and power built right into the cage.

The cables on the drive cage measure 18″ long and should have no problems reaching the ports on the motherboard.

My first thoughts on the latch were that it in fact was the latch to hold the door shut, instead it is more of a lever to pry the door off of the pair of magnets that hold it shut.

The power supply can be run directly below the expansion slots, or it can be moved to the opposite side. If you’re running a truly power hungry system you can opt to run a pair of power supplies in the Corsair Obsidian 900D Super Tower.

I have mixed emotions about thumb screws to hold graphics cards in place. Fortunately most thumb screws have a spot for a phillips head screw driver to secure it in place. There is more than enough expansion slots in the 900D to run quad SLI/CrossFireX with a couple to spare.

We saw what came inside this box earlier on, but this is where we found it while we were perusing the case.

Not only did Corsair supply us with a plethora of wire management cut outs in the motherboard tray, but they also supplied us with sets of wire management clips on the back of the motherboard tray. Closing the side panel while hiding the wires behind the motherboard tray shouldn’t be an issue, Corsair has built the Obsidian 900D with a full inch (25mm) between the back of the motherboard tray and the side panel.

The clips on the back of the tray are pretty simple to use, it’s a wonder we haven’t seen these before.
