"The W0023 doesn’t look an appealing buy to me. This power supply exceeds by just a little the requirements of the obsolete ATX12V 1.3 standard, and in such cases you should consider the allowable current on the +12V rail rather than the total wattage of a unit. Here, we’ve got 22A or 264W. It means that in a modern computer that consumes most of its power from the +12V rail the maximum allowable load on the PSU will be not 560W but 264W plus 30-40W more on the low-voltage rails. That is, about 300 watts in total. So, if you are comparing the W0023 with newer power supplies, you should regard it as a 300W unit. Well, an absolute majority of home computers will be quite satisfied with 300 watts of power, but the price of a power supply depends directly on its specified wattage. It means the W0023 is rather expensive in comparison with new ATX12V 2.0 units, yet there is no sense in this overpayment"
