The Corsair HX1050 power supply casing with its pressed parallel lines, slightly textured matt black paint finish and internal black gloss cooling fan grill certainly looks the part.
The rear panel hexagonal holed exhaust grill occupies all the available space around the IEC mains input socket and a large mains on/off rocker switch. The modular cable connector panel on the front face is colour coded and labeled to avoid confusion at the wiring stage, blue for PCI-E/CPU and black for peripherals. The captive cable set, fully sleeved, leaves the power supply via a plastic lined port to prevent cable damage from bare metal edges.
The two side panels carry identical labels, one side inverted, that clearly show the model number alongside the Corsair logo. The fan grill is internally mounted and carries a white Corsair logo at its centre. The bottom of the power supply is used to show a comprehensive specification label.
The captive cable set consists of a 20+4 pin motherboard connector, one 4+4 pin ATX12V/EPS12V connector and two 6+2 pin PCI-E connectors. The large modular cable set will provide enough connector options for most users. The modular 4+4 pin ATX12V/EPS12v and PCI-E cables are of the conventional round sleeved design whilst the peripheral cables use flat black ribbon cable that does make them a little easier to route at the build stage.
The fan of choice this time is a quality Yate Loon dual ball bearing D14BH-12 rated at 12VDC/0.7A. A quick look at the specification for this fan shows an impressive 140CFM air flow but with a maximum 2800RPM and a rather loud 48.5dB noise level so let's hope it's throttled back a little. A clear plastic baffle is fitted immediately behind the fan to direct the air flow where it's needed.
The internal layout is neat and the printed circuit board, although a little cluttered and untidy in places is no different to many other power supplies in its class. The two primary capacitors are by Panasonic and on the secondary Nippon Chemi-Con, both with the more welcome working temperature of 105°C.
The Corsair HX1050 is very well packaged with a good set of accessories and on the outside it looks like a "professional" unit with excellent build quality. It's claimed use of high quality Japanese capacitors holds true and internally it looks very much like other power supplies in its class. No problems so far, so let's move on.
