We were very impressed by this new power supply from Huntkey. After only reviewing junk coming from this factory, we were very happy to see that they can manufacture good products.

Jumper 550 exceeded our expectations in all possible ways: high efficiency all the times, outstanding voltage regulation, ultra-low noise and ripple levels, lots of very long cables and, the best of all: we could pull up to 730 W from this unit (the manufacturer promises this unit can deliver 600 W).

Interesting enough the internal part number from this unit inside Huntkey is HK650-53PP, which suggests a 650 W power supply. Most likely the manufacturer lowered the labeled wattage in order to be able to get the 80 Plus certification, an amazing departure from the company’s old policy of labeling their products with peak (fake) wattage.

We are more than proud to give our Golden Award to this unit.
