Rocketfish 700 W Power Supply Review


Rocketfish and Dynex are two brands owned by Best Buy sold only on their chain of retail stores (and also on their website, of course). Today we are going to review Rocketfish 700 W, a power supply featuring two auxiliary power cables for video cards, active PFC and a 120 mm fan. Costing USD 165, is it worth the price? Can it really deliver 700 W? Read on.

Rocketfish and Dynex power supplies are manufactured by Huntkey, and we were very curious to review these power supplies from Best Buy for two reasons. First, with more than 1,000 stores worldwide you can find at least one Best Buy store in every major American city. So these power supplies can be found on every corner of the country. Second, we had already reviewed a Huntkey power supply that couldn’t deliver its labeled power, so we were really interested in knowing if that was a problem with that particular model or if all Huntkey models are labeled with a power capacity higher than they can actually deliver.

Rocketfish 700 W is rebadged Huntkey Titan 650 W (HK650-52PEP). Hum… The original manufacturer says this is a 650 W power supply, so can it really deliver 700 W? Wait and see…

On Best Buy and Rocketfish websites the complete specifications for this power supply is missing. In fact, the box and the websites bring conflicting information: both websites say that this is an ATX12V 2.0 power supply, while the product box and label say it is an ATX12V 2.2 product. The box also lists all protections present on this power supply, while the websites and the product manual fail to list them. Efficiency is only mentioned on the product box (80%), but active PFC is mentioned everywhere.

This power supply comes with a 24-pin motherboard cable (it comes with an adapter for you to convert this plug into a 20-pin one), an ATX12V cable, an EPS12V cable and six peripheral cables: two auxiliary power cables for video cards with 6-pin connectors, one cable with four standard peripheral power connectors, one cable with three standard peripheral power connectors and one floppy disk drive power connector and two cables with three SATA power plugs each.

The number of cables is adequate even for the exigent user.

On this power supply all wires are 18 AWG but the ones used on the SATA power cables, which are 20 AWG (i.e., thinner). Also on the peripheral cables the wires coming from inside the power supply are 18 AWG but the wires connecting the first plug to the other plugs are 20 AWG. We’d like to see all wires being 18 AWG.

On the aesthetic side all wires are protected with a nylon sleeving, but this protection doesn’t come from inside the power supply housing.

Now let’s take an in-depth look inside this power supply.
