Corsair Obsidian 800D

9.7 Overall Score

We will begin our system setup and installation page by taking a look at the specifications of the Corsair Obsidian 800D.

After reading over the specs, our list of components is as follows:

Main setup…

  • Foxconn Inferno Katana P55 Motherboard
  • Intel Core i5 661 Processor
  • 3GBs Corsair Dominator GT DDR3 2000 Memory
  • BFG GTX 260 55nm
  • 128GB Samsung SSD
  • 1x1TB HDD and 1x2TB HDD
  • Blu Ray/DVD-RW Optical Drive
  • NZXT Sentry Fan Controller
  • Creative X-Fi Platinum Soundcard
  • Corsair HX850W Power Supply
  • Custom Water Cooling

Secondary setup…(all other hardware not listed below is same as above, except water cooling setup)

  • ASUS Rampage II Extreme X58 Motherboard
  • Intel Core i7 920 Processor
  • 6GBs OCZ DDR3 1600 Memory
  • Water Cooling used is the Asetek CPU cooler which the Corsair H50 was designed after

Our reasoning for the two setups is to show the water cooling options you have with such a large case. The Asetek CPU cooler is basically the same design as Corsair’s H50 unit. Air cooling was skipped in this review for a simple reason: this case can fit any CPU aircooler available in the market today and to be honest, the Obsidian 800D was built to be a water cooling tower.

The 800D has 4 hot swap bays located behind a door on the front of the tower. Each bay supports the two main HDD and SSD form factors, 3.5” and 2.5” respectively. Installation is very straight forward. Four screws hold the 3.5” HDDs in place from the side mounting position. SSDs and other 2.5” HDDs attach via screw holes located at the bottom of each hot swap tray. Once the HDD/SSDs are installed, you slide it in place and make sure to secure the drive with the locking mechanism on each tray. This ensures that a solid contact with the back plane has been made.

To finish up the hot swap HDD/SSD installation, you need to connect power to the back plane as well as the SATA cables. A SATA power adapter is included with the 800D as well as four SATA cables. The adapter and cables were used in this install. We must give you a word of caution when using the SATA power adapter included by Corsair. It fits very snuggly and we recommend you make sure that it is not bending the back plane in any way or you may run into issues with connectivity.

The power supply is situated in the bottom section of the case. There are two grommet wholes providing routing for the cables throughout the chassis. Our preference for power supply location is at the bottom of a case. We feel that this gives the best cooling capabilities for the PSU as it draws in air from underneath the chassis and away from other heating sources. A simple, yet effective design implemented in the 800D is a slight widening of the space between the back of the motherboard tray and the case panel. This additional space allows for easier routing of cables and will not cause the side panel to bulge due to the bundle of cables running on the backside of the motherboard tray. Below you can see a snapshot of that added space along with ventilation holes located at the back of the chassis.

With the power supply and HDD’s mounted, we move on to installing the water cooling setup and all other hardware components.

As you can see, the Feser Xchanger 360mm radiator fits easily inside the Obsidian. The extremely large amount of space inside this case allows for easy placement of the reservoir and pump. Normally, we would locate the pump in the bottom section of this case, but we lacked adapters to make routing the tubing workable in this build. With the pump resting on the compartment divider, we experienced an increase in vibration and noise from the pump. Adding some sound insulation or neoprene should help alleviate the noise if you choose to position the pump as we did.
With all hardware installed, the build looks very clean and uncluttered. It was amazingly simple to have our system look like it took days to clean up the wiring, when in fact, it took about 2 hours to finish the complete build. That does not include time spent leak testing the water cooling setup.

With our first build complete, we take a step back to bask in the simplistic beauty of the Corsair Obsidian 800D. The front shot shows the optical drive bays filled to the brim while the side shots give you a view of the majestic interior. One tiny issue we had with the windowed side panel is that it stuck when trying to remove it.

Here we see what the system looks like with Corsair’s H50 water cooling system installed on a Rampage II Extreme motherboard. This build takes less time than our first one due to the maintenance free CPU water cooler and the fewer components being used.
