We had our differences with Huntkey in the past, but we have to tip off our hat to them. The Jumper 300G Planet3dnow.de Edition is a remarkable power supply, maybe the only 300 W high-end unit available on the market today. This power supply can really deliver its labeled power at high temperatures. In fact, we could pull up to 400 W from it – a huge departure from older Huntkey power supplies that could only deliver 100 W below their labeled power. Voltages are closer to their nominal values than necessary (3% regulation), noise and ripple levels are very low, and efficiency is very high, between 88% and 91%. It also comes with a six-pin power connector for video cards, which is rarely seen on power supplies below 450 W.
If you are building a PC that won’t pull a lot of power (as a matter of fact, 300 W is more than enough for virtually all basic computers) and want to have “the best” power supply, the Jumper 300G Planet3dnow.de Edition is highly recommended.
Of course, high quality and high performance comes with a price. At € 64.90 (USD 94), it is a very expensive unit.
