The Corsair Carbide 330R Titanium Edition Quiet Mid-Tower case is designed to mount a standard ATX style power supply at the bottom. As a test, we installed a Corsair CS850M PSU into the 330R chassis. The power supply dropped easily into position and is secured with four screws on the backside panel. Installing a typical (160mm deep) PSU will leave you with 5-3/4” of space between the PSU and HDD cage for cables. The power supply can be mounted either with the fan up to pull air out of the case or with the fan down. The dust filter covered opening on the bottom of the case allows outside air into the PSU when the PSU is mounted with its intake fan down.
The Carbide 330R case is designed to mount a full spectrum of motherboards including E-ATX, ATX, MicroATX and Mini-ITX form factors. We installed both a Mini-ITX and a standard ATX motherboard into the 330R and in both cases everything lined up perfectly. And there is a large cutout behind the CPU socket area to facilitate installing/changing CPU coolers.
(Standard ATX motherboard)
We also installed several VGA adapters to test the fit and once again everything lined up as expected. The expansion card slots all use thumb screws and the 330R case will support cards up to 450mm (17.7”) long.
External 5.25” Optical Drive
Our 5.25” Blu-ray player slid easily into position and locked in place without tools as advertised. Note: If you plan to install a dual radiator up top it will most likely block the top 5.25” drive bay.
Internal Hard Disc Drives
The internal 3.5” / 2.5” HDD trays are one piece plastic. Each tray comes with four steel pins mounted in silicone vibration isolation washers that are used to mount 3.5” HDDs; just flex the plastic tray and drop in the HDD. No tools required. To mount a 2.5” SSD you just pop out the back corner pin and use the supplied machine screws to attach the 2.5” device to the tray.
