39 300-450 watt PSU group test: cheap and good

What should you get for an entry-level PC?



Most of the power supplies in this test have a capacity of 400 or 450 watts, and not as many are 300 or 350 watts. Only the Huntkey CP models do not mention the maximum continual load and instead the peak capacity. The 400W and 350W models have a maximum continuous capacity of 300 watts and 250 watts, respectively. All others mention their maximum continuous capacity in their product name.

Prices of the PSUs in this segment vary a lot. The cheapest one, that same Huntkey CP-350, can be bought for 19 euros. The most expensive power supply in the test, the Seasonic Platinum Series Fanless 400W, is available for an average of 134 euros. The name indicates why, it's 80 Plus Platinum certified and completely silent. Most of the PSU are priced more modestly, between 45 and 70 euros.
