Corsair ship the HX1500i in one of their famous yellow accented boxes. The name of the product is listed top right, and they include a photograph of the supply in the center with a logo showing support for Nvidia 50 series, as well as two Cybenetics certification badges.
The rear of the box gives a lot of focus to the LINK support, showing fans, AIO coolers, pumps and radiators attached. Along the bottom are graphs highlighting power efficiency and fan noise levels under various load conditions.
Inside the main box we find two sections. One with the power supply itself sandwiched between foam panels and the other home to the cables and accessories.
Corsair include a regional specific power connector, some user documentation, 10x cable ties and some mounting screws.
The quality of the cabling is very high, they are all individually sleeved (debossed). Corsair also include some iCUE LINK / USB cables and connectors.
The table above shows all the cabling between the three power output capacities of the HXi Shift power supplies. Length and connector spacing on all the cables is perfectly fine. The primary cables are all 16-18AWG.
