600-650 watt power supply round-up: 25 models put to the test

More power for more powerful systems



When building a powerful system, we'd recommend going with a power supply of above average capacity. Although a 500W unit is actually capable of powering a pretty beefy system these days, choosing a 600-650W unit does offer a little more flexibility at only a modest price increase. Therefore, we tested 25 such power supplies, with prices ranging from $30 / £22 / €30 to $150 / £120 / €150.

About six months ago, we tested a substantial amount of 500-550W power supplies. Reviewing said test reveals that a power supply from the 500W range is powerful enough even for a high-end system featuring a Core i7 4790K and an Nvidia GeForce GTX 980. However, if you want more, such as a Socket 2011 CPU, a GTX 960 SLI setup, or a whole lot of hard drives, having a little more power might come in handy. Power supplies from the 600-650W range would make for an excellent choice in such a scenario – and they just happen to be the subject of this test.


Our test sample consisted of 25 models with prices ranging from $30 / £22 / €30 to over $150 / £120 / €150; only the price of the SilverStone ST60F-PB was unknown at the time of writing. Just as was the case for the 500-550W power supplies, purchasing the absolute cheapest model is never a good idea, as is illustrated by the Codegen Super Power 600W. On the other hand, going for the most expensive model won't save you money in the long run, either.

Although the prices of today's line-up cover almost the exact same range as those of the previously discussed 500-550W power supplies, you'll find that the higher capacity units do on average cost around $20 more. If you want a power supply from the 600-650W bracket, you'll often times have to cough up over $60 / £50 / €60. Excluding the Codegen "600W" unit that'll set you back around $30, only the Cooler Master B600 costs significantly less at $50 / £43 / €50. Six models have prices of between $60 / £50 / €60 and $70 / £55 / €70, another six cost between $80 / £60 / €80 and $110 / £80 / €110, six more are positioned between $110 / £80 / €110 and $120 / £87 / €120, and the final four cost over $140 / £100 / €140. As was mentioned previously, the price of one of the models was unknown at the time of writing. All this is based on mean prices from the Hardware.Info price comparison tool. Those who actively seek out the lowest prices can often times easily save around $15 / £11 / €15.
