Corsair Obsidian 900D Super Tower
It's been a long time coming, the successor to the infamous Corsair Obsidian 800D is finally upon us! Today Corsair is lifting the lid on their latest secret and letting us show you everything that we've been hiding. A little over three and a half years ago Corsair threw their name into the ring with other case manufacturers with the 800D. The Obsidian 800D was a hit for Corsair, and they had successfully entered the case market. Since the launch of the 800D they have successfully brought several chassis series out, including the Graphite Series, Vengeance series, and the Carbide series. Each series with different features and significantly different styles. The Obsidian series has always been my personal favorite, probably because I like the simplistic and functional styling. That and I think they're just cool as hell! The 800D and now the 900D are built for the computer enthusiast. Being built for the enthusiast means a couple of things. First off it has to be functional, as we go through the Obsidian 900D today I'm sure it will prove that it meets that requirement. Second, it has to be built to last. Again I doubt that will be an issue. The caveat to meeting these requirements is that the quality has to be up there with the best of them. This can and does drive the price up, but for something that's going to last for years and do everything you need it to, it can certainly be worth it! The Corsair Obsidian 900D will hit the streets with a MSRP of $349.99. It's certainly not a budget case, but for those who know the quality of Corsair products... You tend to get what you pay for!
Cooling and airflow shouldn't be an issue when using the Corsair Obsidian 900D. Out of the box the Obsidian 900D has four fans installed, one 140mm exhaust fan (AF140L) and three 120mm intake fans (AF120L) in the front of the chassis. Though it's easy enough to add up to eleven (11) more fans! All eleven fans can be 120mm fans, or you can mount 140mm fans up top. Each of the hard drive cages will support a 120mm fan and six fans can be mounted along the bottom of the chassis with the removal or relocation of the hard drive cages down there.
The Corsair Obsidian 900D is designed for those looking to do some serious after market water cooling, and not for the guy looking to run the stock cooler, or any air cooler for that matter. There is no shortage of mounting points for radiators. On the top of the Corsair Obsidian 900D we can mount anything from a 1x120mm Radiator up to a 480mm radiator, down at the bottom we can do the same. The front of the chassis can support up to a 360mm long radiator. The Exhaust fan can be replaced with a single 140mm radiator, and the rear panel side can support a 240mm radiator.
I know some people don't like this feature as much as I do, but I think the magnetic air filters are one of the coolest innovations that I have seen on a case in a long time. I've noticed that some of the slide in filters have a habit of rattling, typically it's only a slight rattle but in a quiet room it can be noticeable. The magnetic filters like the one that's on the door above won't be able to rattle since it's literally stuck to the chassis.
If you're looking for massive amounts of storage, you're in luck! The Corsair Obsidian 900D was built with you in mind. The 900D comes with three hard drive cages that support three 3.5" hard drives or three 2.5" hard drives or SSD's. With the addition of two more hard drive cages, the 900D will support up to 15 hard drives without modding.

The Corsair Obsidian 900D is flat out massive! There's a reason that it was nicknamed Godzilla in the Corsair offices! Even the UPS driver didn't want to carry this all the way to my door, and left it on the side of the house for me. Oh well, guess I don't need to hit the gym after carrying this beast to the office!
While the retail packaging may be important, it's mostly important for protection. The shipping weight for the Corsair Obsidian 900D is 50 pounds (22.7Kgs)! Not only is the case heavy, it's huge! The packaging alone measures 30"x14"x31"! Corsair doesn't use fancy packaging for the cases, there's really no point to it, the product speaks for itself while the packaging get's recycled in the end. So why waste money on something that's going to disappear shortly after receiving the case. While it isn't flashy, the front of the packaging for the 900D boasts a simplistic drawing (doesn't do any justice to the real thing), the question; What will you do with all this space?, and a few suggestoins.
The back of the retail packaging for the Corsair Obsidian 900D gives us another drawing of the chassis, though this time around it's a breakdown of the 900D. To the left we also have a dimensional drawing that shows that the Corsair Obsidian 900D measures 252x649.6x691.6mm (9.92x25.57x27.23 inches)
Along the side of the retail packaging, Corsair has placed a list of the specifications in three different languages; English, French, and German.
The same side features the same dimensional drawing that we saw on the back of the Corsair Obsidian 900D packaging.
The top of the Corsair Obsidian 900D is pretty simplistic, though there is a QR Code that takes us here when we scan it with our smartphone.
Once we open up the retail packaging, the chassis looks to be securely packed with Styrofoam to prevent and damage during shipping.
Removing the Styrofoam from the of the box, we find a rather obscured first glimpse of the Corsair Obsidian 900D Super Tower.
Flipping the packaging over turned out to be the easiest way to remove the Corsair Obsidian 900D Super Tower from within. Once it was removed from the cardboard shell, we could remove the Styrofoam end pieces and the plastic bag to get a good look at the Super Tower Chassis in all it's glory.
The front bezel pieces of the Corsair Obsidian 900D Super Tower were each protected with an additional layer of plastic film. This was probably put on at the manufacturing level to protect them during and after assembly. The top one was also taped into place to prevent it from coming loose, as this one is also the door to the front panel ports.
Within the 900D chassis we found a little brown box that contained all of the screws and other little parts needed for assembling the system.
Now that we have the Corsair Obsidian 900D Super Tower chassis out of the box, uncovered and ready to rock, join us on the next page as we go over the general features on the outside of the chassis!
Corsair Obsidian 900D Super Tower External Impressions
Pictures don't do justice to the enormity of the Corsair Obsidian 900D. There is an absolute reason that Corsair has nicknamed the 900D 'Godzilla'. It measures an impressivex 649.6x691.6x252mm (25.57"x27.23"x9.92"inches), the Corsair Obsidian 800D measured 609x 609x229 mm (23.98"x23.98"x 9.02"). The 900D is larger on every dimension by at least an inch! What I like about the Corsair Obsidian 900D is the pure simplicity in style. It doesn't have any flashing lights, cheap molded plastic designs, or anything that doesn't have a purpose. Nor does it leave anything to the imagination when it comes to the parts used and your build skills. The side panel of the 900D measures 18.5"x15.75". The window and side panel wont hide anything from view. Below the side panel is a panel that can be folded out for access to some of the parts hanging out on the bottom of the 900D Super Tower chassis. We'll look at that soon though.
Taking a look at the opposite side of the Corsair 900D its a little less exciting that the windowed side. Though we do have the same door down at the bottom of the chassis.
Taking a look at the back of the Corsair Obsidian 900D Super Tower chassis, there are a couple of things that jump right out at us. First and foremost is the expansion slots, the 900D is equipped with ten expansion slots! This is one of the improvements over the 800D that came equipped with only seven expansion slots. Now we can easily set up a quad-sli/quad-CrossfireX with four dual slots graphics cards. The second most notable (at first glance) feature is the ability to run dual power supplies or simply choose where you want your power supply mounted.
Much like the Corsair Obsidian 800D, the 900D side panels are released by pressing the buttons in the corners. This push button technique makes removing the doors incredibly simple to do. Once you depress the button the top of the door can swing out and you can then lift it off of the chassis.
The front of the Corsair Obsidian 900D Super Tower continues the understated design and simplicity that I like about this case. What looks like it might be the top 5.25" bay is actually the front panel behind that door. The power button is visible at top center. Below the front panel door we have four 5.25" expansion bays. The panel that carries the Corsair badge can be removed to reveal three 120mm Corsair A1225L12S fans.
The top expansion bay of the Corsair Obsidian 900D isn't an expansion bay at all. Turns out that this is actually a door to cover up the front panel. To open the door to reveal the front panel simply press and release on the upper left hand corner.
Once you have opened up the door to the front panel, first thing I noticed was the number of USB ports that Corsair has included here. On the left we have a pair of SuperSpeed USB 3.0 ports, and four USB 2.0 ports on the right for a grand total of six ports. To the left of the USB 3.0 ports is a pair of 3.5mm audio jacks for microphone and headset. Dead center of the front panel there is a small reset button while the power button is the larger bar just above it.
Removing the panel is as simple as pulling it away from the chassis. Between the panel and the fans we have a removable dust filter that releases by depressing and releasing the two top corners.
The three Corsair A1225L12S fans are set up as an air intake, pulling cool outside are into the Corsair 900D. The Corsair A1225L12S fans are rated for 32.95 CFM at 1200 rpm.
There isn't much exciting on the bottom of the Corsair Obsidian 900D Super Tower. In each of the corners though, there is a nice heavy duty rubber foot to protect the surface that you set the system on.
The entire top of the Corsair Obsidian 900D Super Tower chassis is an air filter. Once this is removed we can scope out what type of cooling can be run up here.
We've now seen how impressive the outside of the Corsair Obsidian 900D Super Tower is, Let's move to the inside and see whats hiding on the inside!
Inside the Corsair Obsidian 900D Super Tower
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.
Installing Parts into the Corsair Obsidian 900D Super Tower
We started out throwing our GIGABYTE X79-UD7 motherboard into the Corsair Obsidian 900D. The GIGABYTE X79-UD7 is an XL-ATX motherboard, and it looks like a mITX motherboard inside the 900D!
In the top of the Corsair Obsidian 900D we mounted a triple 120mm radiator with remarkable ease! We could have gone with a quad 120mm or a triple 140mm radiator as well. With nearly 4.25 inches between the top of the chassis and edge of the motherboard there is more than enough room to use a push/pull fan configuration in addition to the radiator.
Lowering the side door, surprise! We were able to mount a radiator here as well, though we could have run a quad 120mm radiator here as well! Despite having all these parts in here so far, the case certainly looks empty!
When it's all said and done, there is still plenty of room left inside the Corsair Obsidian 900D! Currently we have the GIGABYTE GA-X79-UD7 XL-ATX motherboard, EVGA GeForce GTX 470 Hydro graphics card, two 120mm X 360mm radiators, six Yate Loon 120mm fans, 3 Corsair 120mm fans, one Corsair 140mm fan, DVD burner, and a Corsair HX750 power supply! Inside most cases we would be using a shoe horn to fit all this! Inside the Corsair Obsidian 900D Super Tower we can still fit a 140mm radiator and two more 2x120mm radiators! This thing is a beast of epic proportions!
Once the Corsair Obsidian 900D Super Tower is all closed up, it tips the scales at nearly 65 pounds. This certainly isn't a case that you will be taking to LAN Games with you! Unless of course you're one of those that likes to carry around a boat anchor for fun.
Final Thoughts and Conclusions
When I first saw the Corsair Obsidian 800D more than three and a half years ago, I fell in love with it. I was always upgrading, changing my water cooling around, and constantly tweaking my system. I never did get around to picking up the Corsair 800D, I always kind of regretted that. Here we are three and a half years later and we now have the successor to the 800D! The fine folks over at the Corsair labs have unveiled the Obsidian 900D! We first caught a glimpse of the new Obsidian 900D at the Consumer Electronics Show back in January 2013, pretty sure my first thought when I finally got to see it that fateful night at the V Bar in Las Vegas NV. was somewhere along the lines of epic! For the most part that still holds true after getting my hand on it. The Corsair Obsidian 900D Super Tower carries a fairly hefty price tag on it, out the gates the 900D will have an MSRP of $349.99 USD. It may seem a little steep at first (and to your significant other), but keep in mind this isn't the kind of case you use for a single build and get rid of. The Obsidian 900D can be used over and over and is a case you can count on for years to come!
There is only one aspect of the Corsair Obsidian 900D that simply bugs me! The front panel of the 900D is so clean and so smooth that they even have a door to cover up the front panel I/O. This gives the front of the chassis a real sharp look. When installing an optical drive we have to remove the cover, this causes that bay to be recessed 3/16" (.1875").
This little issue certainly isn't a deal breaker for the Obsidian 900D and is something that I could get over and live with. It's sSimply something that I noticed during the build that was worth pointing out.
Beyond that little issue with the front bezel, I didn't find anything else that I wasn't wild about with the Obsidian 900D. Except maybe the weight, fully loaded the Obsidian 900D tipped the scales at nearly 65 pounds (29.5Kgs)! This is definitely a system that you wont want to be moving around to often. Don't get me wrong, while the Obsidian 900D Super Tower is a heavy beast, it's not unexpected for a case this size so I'm not faulting it.
The Corsair Obsidian 900D is simply a massive case. While feeling a little lazy I decided that I didn't wanted to take the easy route and use a system that was already built, so I threw the BitFenix Pridigy chassis inside the Obsidian 900D Super Tower!
The Corsair Obsidian 900D fits motherboards of all sizes. Though the 900D might be a little overkill for the mITX motherboard above. It does show that the 900D has a very versatile design and will be able to accommodate us for years to come. Like all Corsair Obsidian PC Cases, the 900D Super Tower carries a 2-year warranty.
At the time that I'm writing this, the Corsair Obsidian 800D is available for $299 at the Corsair site, though a little google-fu and it can be found for as little as $273.99 shipped. Today, the Corsair Obsidian 900D Super Tower is starting out with a MSRP of only $349. For only ~$75 more you can get the latest and greatest case from Corsair! You may have a little bit of time before it becomes available though, retail availability is expected to be sometime in May of this year. Take if from somebody who has had some hands on time with the 900D, it'll be worth the wait!
Legit Bottom Line: The Corsair Obsidian 900D is certainly a beast of a case. If you're looking to install insane amounts of water cooling, massive motherboards, graphics cards, and to simply have the room to expand your system as needed without the concern if it will fit or not, there will be few if any that will meet your needs like the Corsair Obsidian 900D Super Tower!
