Huntkey Jumper 600B Power Supply Review

Conclusions

The Huntkey Jumper 600B proved to be a very good mainstream power supply, with an outstanding voltage regulation (three percent regulation during all tests), high efficiency up to 87%, and extremely low noise and ripple levels at +3.3 V and +5 V outputs. At +12 V, however, noise and ripple were higher than we’d like to see to consider a power supply “flawless,” but still below the maximum allowed. Also, the lowest efficiency we saw was 82.4%, and several power supplies with the 80 Plus Bronze certification we reviewed can’t provide 82% efficiency at full load under real-world scenarios, so this is another positive point for the Jumper 600B. The cable configuration is excellent for a mainstream 600 W unit, coming with four video card power connectors, a feature not usually seen on 600 W units. On the other hand, some users may find the cables too short.
