CORSAIR Obsidian 750D Computer Case Review

Cases & PSU/Cases by leeghoofd @ 2013-10-03

CORSAIR has established grounds in the enclosure market. At start only with the high end versions in the form of the Obsidian and Graphite cases. Later on targeting another segment of the market, with the more affordable cases, under the Carbide brand name. The Obsidian series are straight competition for big names as Lian-Li, sporting high build quality, offering maximum hardware compatibility and they are multi GPU ready, plus the possible liquid-cooling options are a big bonus. The mixture of steel and brushed aluminum, enhances the rigidity and adds that little extra touch of elegance to the CORSAIR Obsidian enclosures. The brand new 750D model is a full blown tower case and looks at first glance like a trim-down version of the 900D flagship. Nevertheless what is most exciting is, that this case is retailing at the price of a high end Mid-Tower chassis. Time to take a closer look at the CORSAIR 750D Obsidian case.

The Build, Temperature and Noise Results

Without any surprise the ease of installation in a full tower chassis of this grade is peanuts. Just shake it and it will all fall into place. We build in our usual X79 Sabertooth motherboard and the CORSAIR H100i 240 rad cooler. The GPU used this time was an ASUS 7970HD Matrix PE card. Even while being slightly longer then the reference model, the GPU still has got loads of room to spare from the modular top HDD cage.

Cable management couldn't be any easier, thanks to the numerous cutouts and the massive amounts of space behind the motherboard tray.

No surprises in cooling performance, thus those looking for shockingly low hardware temperatures here, please look elsewhere. The Obsidian 750D is even in it's out of the box configuration a well-ventilated enclosure. We also opted to test the 140L fans to run flat out versus the PWM mode, however not much temperature differences to spot, on the utilized X79 Sabertooth motherboard

The noise level generated by the 140L fans is slightly below the versions used on the 540 Air, we measured 28dBa, which is acceptable, yet this is slightly audible in a quiet living room.
