Corsair TX850w ATX PSU
Removing the four screws and lifting the lid on the TX850, the first thing that hits you is just how spacious it is inside. Normally, most manufacturers cram components wall to wall, making the casing as small as possible. However, inside the TX there is a good 20mm gap between the PCB and casing on one side, and 5-10mm on the other. Everything inside the unit is tidy, with all cables entering the casing being tightly bunched together and decent space between each of the components allowing them to 'breath'.
Three black aluminium heatsinks run in parallel across the unit, providing cooling for the attached mosfets. Positioned middle-right we can see the large primary transformer that deals with the +3.3v /+5v and +12v rails, and over to the left of it is yet another transformer, only much smaller, and responsible for dealing with the +5vsb (Standby) rail.
Cables & Connectors
A total of ten cables extend from the unit branching out into 8xSATA, 8xMolex, 4xPCI-E, 1xATX and 1xEPS connectors. Each and every cable on the unit is sleeved in a black mesh finished off with black heatshrink at the ends. Just like a lot of other units we're reviewed recently, Corsair have decided not to carry the sleeving all the way into the PSU, instead stopping just a couple of centimetres short. This doesn't exactly score points in the looks department, but it does enable each of the nine protruding cables to have a much greater bend radius, which could prove helpful if the PSU were to be installed in a confined space.
Similarly, both the 8-Pin EPS-12v and 24-Pin ATX connectors can also be converted back to 20-Pin ATX / 4-Pin P4-12v standards for compatibility with older motherboards if required.
