For our tests, Corsair sent us the retail package of the Corsair HX620W Power Supply with part number CMPSU-620HX. Its retail price can range from US$140~160. The package is quite large.

Let's open the box:

The PSU is well protected in plastic foam.

The PSU itself is typical in size (150 x 140 x 86mm) and is certified for ATX v2.2 standard. There is a 120mm cooling fan in the base. The external black matt finish looks nice and the case feels solid. There are no sharp edges, so you can handle it without any worries of scratching anything.

The only cables that are initially attached are the:

• Power Supply unit with 24-pin main power connector
• 4-pin +12V connector and 8-pin EPS12V connector

The power supply specs indicate that it can be used for "heavy" use, in other words for SLI/Crossfire setups:

The rear of the PSU is honeycombed to help air ventilation. This design with the fan in the base of the PSU case, helps draw air out of the computer case and out the rear of the PSU.

There is a pouch that contains all the cables:

Removing the bag contents we have:

1. 2 x 800mm 4-pin peripheral power connector cables with three connector heads.
2. 2 x 450mm 4-pin peripheral power connector cables with two connector heads.
   Note: The 4-pin peripheral power connector is widely used on devices such as IDE hard drives, CD-ROM drives, optical drives, and on certain AGP video cards.
3. 2 x 550mm PCI Express connector cables.
4. 2 x 800mm SATA connector cable with three SATA connector heads.
5. 1 x 650mm SATA connector cable with two SATA connector heads.
   Note: The SATA power connector is used on SATA hard drives or SATA CDROM drives.
6. 1 x Y-adapter with a 4-pin female peripherals power connector at one end and two female small 4-pin Floppy power connectors at the other.
   Note: The small 4-pin power connector is widely used on floppy drives, and certain fan control panels.
7. 1 x Y-adapter with a 4-pin female peripherals power connector at one end and two female 4-pin peripherals FAN ONLY power connectors at the other.
   Note: The Fan only power connector is strictly used on fans.

In addition, an AC Power cord, several cable ties and mounting screws are included
