Much like with most Corsair power supplies, the chassis of the AX650 is entirely black and sprayed with a matte paint. The design of this power supply is very subtle considering its class and if not for the side stickers one could hardly tell the difference between it and a medium-class power supply. The AX650 is only 160mm long and should easily fit inside any case able to house an ATX power supply.
Corsair’s usual decorative stickers with the unit’s model and company logo can be still found at both sides of the power supply. The chassis also forms a frame around the stickers, creating a quality visual effect.
The sticker with the unit's electrical specifications can be found at the top of the chassis and there is no frame surrounding it. This sticker will only be visible in cases which have the PSU compartment placed at the bottom of the case.
The rear is entirely perforated to allow for the air pushed by the cooling fan to escape towards the outside of the case. The unit uses a standard AC power cable and there is a standard rocker on/off switch at the rear, as well as a small sticker with the series logo.
The front side of the chassis is littered with the connectors of the modular cables. This power supply is fully modular, meaning that not even the ATX cable is hardwired to the body of the unit. Strangely, there is no sticker or even a hint about which cable goes where, although the connectors are keyed and the user cannot insert a cable’s plug inside a wrong connector. This unit offers the following number of connectors:
24-pin ATX connector
1 x 4+4 pin 12V CPU connector
4 x 6+2 pin 12V PCIe connectors
8 x Molex connectors
8 x SATA connectors
2 x Floppy connector
*Editor’s note: the floppy connectors utilize Molex connectors through adapters.
