Connectors & cabling
Most wires in the cabling are 18AWG (besides a few trivial ones like PWR On or Power Good). Only the first 6+2pin PCI Express connector has eight 16AWG wires. Main cables are sleeved while the others are welded to form flat ribbons. The molex connectors have unplugging clips but no pins are golden-plated. There are three extra wires on the +5 V, +12 V and ground pins, most likely for voltage regulation feedback.
In total, we have:
- Main ATX (20+4pin): 60 cm
- 1× ATX 12 V (4+4pin): 65 cm
- 2× PCIe (6+2pin): 60 and 73 cm
- 6× SATA: 2× 52 cm, 2× 67 cm and 2× 76
- 4× peripheral molex: 1× 45 cm, 1× 55 cm, 1× 65 cm and 1× 75 cm
- 1× adapter molex-to-Berg for FDD: 10 cm
Casing & cooling
The casing is made from 0.9mm SECC steel (so it is quite tough) and has matt black (possibly powdered) lacquering. The fan grille is made from wire so this should also add to overall quietness of this unit. The whole casing has like a cut corners, which serve no practical purpose, only add to manufacturing costs.
The backside for exhaust air is made with hexagonal holes which are almost around the whole AC receptacle as can be seen on the picture in previous chapter so there will be no pockets of hot air inside the unit. However, there is a small blind spot on the primary side. The fan used is Corsairs own NR135L, 135mm low-speed rifle-bearing fan. It is rated at 1500 RPM, 57.71 CFM and 25.5 dBA and with expected lifetime of 30000 hours at 40 °C.
