Product Description

Product Description

The Obsidian Series 550D has been carefully engineered for noise reduction. The front and side panels are insulated with sound dampening material, and the hard drive trays and fans have soft silicon mounts to absorb vibration. The top and side panel vents are covered for noise reduction if you're not using them to install your own fans, and even the intakes are angled to reduce air noise. The rigid, stamped steel and brushed aluminum case holds some remarkable technology that makes it easy to build great systems. There's built-in USB 3.0 support, and the drive trays work with 2.5" SSDs. The removable hard drive bays allow customization for extra-long graphics cards and maximizing airflow. And, the easy-access side panels come off at the touch of a button for easy upgrades or simply admiring your work.

From the Manufacturer

A revolutionary combination of noise reduction and cooling.

Obsidian Series 550D is carefully engineered for noise reduction and sound isolation. But, it’s not just about keeping things quiet — there’s amazing cooling potential, lots of expansion flexibility, and the durability that Obsidian Series is renowned for.

Obsidian Series 550D
Stamped steel meets rugged aluminum for a look that’s subtly elegant.

Superior airflow for high-performance PCs.

Obsidian Series 550D comes with two front-mounted 120mm intake fans and one 120mm exhaust fan – more than enough for delivering the airflow required for a high-performance system. But if you’re pushing past high performance and into the realm of extreme-performance overclocking, there’s room for a lot more. The top panel provides room for two 120mm or 140mm fans, or a 240mm radiator for compatibility with Corsair Hydro Series CPU coolers and other liquid cooling systems. The side panel has mounting points for another two 120mm or 140mm fans for cooling multiple GPUs. In total, the 550D offers ten 120mm fan mounting points, six of which can also accommodate 140mm fans.

The silent treatment.

With many high-end PC cases, cooling is often provided without consideration for noise. Not so with the 550D: the front and side panels are fully lined with sound-damping material, and the top and side panels have their own sound-insulated vent covers to reduce noise leakage from unused fan mounting locations. The front air intakes are angled away from the front of the case for noise reduction, and the fans and drive bays use silicone mounts to reduce vibration noise. The result is a platform for building high-performance PCs you can live with.

The diamond-cut aluminum front panel includes two USB 3.0 connectors and audio connectors.
Smart features for serious builders.

The extra touches like magnetically mounted dust filters and one-button side panel removal make building fun, and using a 550D-based system a rewarding experience. Expansion is easy, with eight expansion slots, six tool-free hard drive bays with removable caddies and integrated 2.5” SSD support, and four tool-free optical drive bays. The top drive cage can be removed to accommodate GPUs of up to 452mm in length. The diamond-cut brushed aluminum front panel houses two high-speed USB 3.0 connectors and audio ports.


The Obsidian Series: Designed by builders, for builders

World-class Obsidian Series cases are made from stamped steel and brushed aluminum, providing both outstanding durability and great looks. State-of-the-art features are engineered with the singular purpose of meeting the needs of professional builders, high-end system integrators, and performance enthusiasts. Builds are straightforward and efficient, and there’s room for nearly any system configuration you can imagine.

Corsair's PC enclosures are some of the finest enclosures you can buy. The case that started it all was the Obsidian 800D -- a premium full tower beast with advanced features and a drool-worthy appearance. Since then, Corsair has added the Graphite Series, Carbide Series, and Vengeance Series cases to their stable of acclaimed enclosures. With a complete line of cases to suit a variety of tastes, performance requirements and budget, the only type of case missing was a silent case, until now. The Obsidian 550D is a premium, mid-tower case with sound isolation characteristics that rounds out Corsair's collection of enthusiast enclosures.

- Gorgeous looking case
- Very quiet
- Plenty of cooling options
- Reversible front door
- Nice build quality
- Tool-free drive bays
- Can fit 452mm GPUs
- Removable magnetic dust filters
- Affordable online price

- Front panel can be difficult to flip open

The Obsidian 550D comes with a quick start guide and an assortment of screws for drives, PSUs and fans. It also comes with a couple of wire mounts, nylon zip ties, and a USB 3.0 to USB 2.0 adapter, just in case your motherboard doesn't have a USB 3.0 header. The install kit is a thoughtful inclusion for system builders and one that seems to accompany all of Corsair's cases.

The 550D's appearance is a slight departure from the 800D and even the 650D. The most obvious change is the exposed silver I/O panel at the very top of the 550D. The panel includes audio ports, the power and reset switches, drive activity light and two USB 3.0 ports.

This was my first system build. Therefore I don't have any reference point to compare this case against other cases. Only what I read. I selected this case because I wanted USB-3 connectors on the front panel that could be connected directly to a USB-3 header on the MOBO. I also needed the case to hold an ASUS P9X79 Deluxe ATX MOBO with a Corsair H100 CPU cooler and a Corsair AX850 PSU. Another very important criterion was that the system be very quiet.

If you are one who needs written instructions to assemble the system components into a case, don't' get this case because there are none. Evidently, Corsair assumes that if you need instructions, you most likely should not be building a system.

The MOBO attached perfectly to the case. The case came with all the MOBO support connectors preinstalled. The PSU slid in and fit like a glove. All the cables from the front panel devices were clearly labeled. This made finding the correct location on the MOBO to attach them a breeze. The hard drive, SSD drive and the optical drive all installed almost too easily. Being my first build I feared the worst.

I love how the front door swings both left and right. Nice touch. It is also removable for those who don't want a door.

With all the good design features, there is one issue with the build that the Corsair engineers should have addressed - they should have added another 0.5 inches to the height of the case so that there would be a little clearance between the MOBO and the H100 fans. Yes everything fits, however the fit is so tight that one of the H100 fans touches a heat sink on the ASUS P9X79 MOBO. Perhaps a different MOBO would not have this problem but why not add the extra 0.5 inch and be able to handle this MOBO as well.

The Corsair 550D is a very well designed and quality-fabricated, tool-less computer installation case with a conservative, tasteful appearance. It's big marketing appeal is in acoustic insulation, the only such, a newcomer in their lineup, and it definitely does not disappoint in that aspect. I can barely hear its running when it is in operational mode, after complete booting. There have been caveats as to whether one has to deal with the side-effect of poor ventilation related to that insulation, but my computer runs coolly, with a relatively silent system where CPU heatsink fans run at close to baseline speed maintaing low CPU and ambient temperature, but I do not overclock and have only one GPU which has 3 quiet fans. The PSU's fan is almost never on also indicative of low ambient temperature, and, of course an efficient PSU(gold ATX Corsair 850W). Reviewers have commented, from their measurements, that even in overclocked systems, the 550D with its stock fans functions surprisingly and acceptably well in maintaining adequate ventilation, but there are options, in its flexible design, to take off the push-activated covers on case windows in the side and top panels, both of which have magnetic dust covers and the options for installing additional fans.

The 550D is a moderately large mid-size case, about an inch shorter in height than the 650D which would be welcome for increased accessbility to the superior aspects of the MB, especially if you mount fans or radiators there, but clearance is accessible.
