Two years ago, we reviewed the Huntkey Jumper 550, which exceeded our expectations. Now it is time to review the Jumper 600B, which comes with the 80 Plus Bronze certification. (Hence the letter “B” after the product wattage; it is important to understand that the 500 W and 550 W models from this family have the standard 80 Plus certification.) Let’s see how the Jumper 600B fared on our tests.

The Huntkey Jumper 600B is 6.3” (160 mm) deep, using a 140 mm sleeve bearing fan on its bottom (Yate Loon D14SH-12).

Different from the 550 W model, the 600B version doesn’t have a modular cabling system. All cables are protected with nylon sleeves, but the sleeves don’t come from inside the unit. This power supply comes with the following cables:

• Main motherboard cable with a 20/24-pin connector, 17.7” (45 cm) long
• One cable with two ATX12V connectors that together form an EPS12V connector, 17.7” (45 cm) long
• Two cables, each with one six/eight-pin connector and one six-pin connector for video cards, 17.7” (45 cm) to the first connector, 5.9” (15 cm) between connectors
• Two cables, each with three SATA power connectors, 17.7” (45 cm) to the first connector, 5.9” (15 cm) between connectors
• One cable with four standard peripheral power connectors, 17.7” (45 cm) to the first connector, 5.9” (15 cm) between connectors
• One cable with three standard peripheral power connectors and one floppy disk drive power connector, 17.7” (45 cm) to the first connector, 5.9” (15 cm) between connectors

All wires are 18 AWG, which is the minimum recommended gauge, except for the wires on the main motherboard cable, which are thicker (16 AWG).

The cable configuration is excellent for a 600 W power supply, allowing you to install two high-end video cards without the need of adapters. On the other hand, some users may find the cables too short.
