So far we haven’t had a good experience with most models from Huntkey. We’ve reviewed seven other models from this brand and only one, Titan 650 W – which was sold in the US as the first version of Rocketfish 700 W from Best Buy stores – survived our tests. Models from Huntkey Green Star, V-Power and Balance King series that we’ve reviewed to date all exploded during our tests. Let’s see if this new 550 W model with a modular cabling system is a good product or if it is a piece of junk like the other models we’ve reviewed from this brand.

The product box has a sticker saying that you can “overclock” (sic) this power supply up to 600 W continuously. We will see whether this is true or not.

Huntkey Jumper 550 is 6 1/4” (160 mm) deep, using a 140 mm fan on its bottom. It features active PFC circuit.

The modular cabling system has six connectors, two for the video card power cables (the red ones) and four for SATA and peripheral power cables (the black ones). The main motherboard cable and the ATX12V/EPS12V cable are permanently attached to the power supply and come with nylon sleevings, which don’t come from inside the unit. All cables use 18 AWG wires, which is the correct gauge to be used. The cables included are:

• Main motherboard cable with a 20/24-pin connector, 20 ½” (52 cm) long, permanently attached to the power supply.
• One cable with two ATX12V connectors that together form one EPS12V connector, 20 7/8” (53 cm) long, permanently attached to the power supply.
• One cable with one six/eight-pin connector and one six-pin connector for video cards, 21 5/8” (55 cm) to the first connector and 5 7/8” (15 cm) between connectors (modular cabling system).
• One cable with one six-pin connector for video cards, 21 5/8” (55 cm) long (modular cabling system).
• One cable with three SATA power connectors, 21 5/8” (55 cm) to the first connector, 5 7/8” (15 cm) between connectors (modular cabling system).
• Two cables with two SATA power connectors each, 21 5/8” (55 cm) to the first connector, 5 7/8” (15 cm) between connectors (modular cabling system).
• One cable with two standard peripheral power connectors, 21 5/8” (55 cm) to the first connector, 5 7/8” (15 cm) between connectors (modular cabling system).
• One cable with three standard peripheral power connectors and one floppy disk drive power connector, 21 5/8” (55 cm) to the first connector, 5 7/8” (15 cm) between connectors (modular cabling system).
• One cable with two standard peripheral power connectors and one floppy disk drive power connector, 21 5/8” (55 cm) to the first connector, 5 7/8” (15 cm) between connectors (modular cabling system).

The cable configuration from this power supply is excellent, with all cables being extremely long, allowing you to easily fit this product on any case regardless of its size and power supply location.

If you pay close attention, you will see that the modular cabling system has four plugs for SATA and peripheral power cables, but the unit comes with three SATA cables and three peripheral cables, so you will have to decide which cables to use. If fact this is a terrific thing, as you will be able to chose between more SATA or more peripheral power cables, depending on your system configuration.
