You needn't spend a fortune for a good PSU. Our testing has demonstrated repeatedly that modern PCs don't need to have huge-capacity PSUs. The latest GeForce GTX 980, the most powerful single-GPU on the market, chews through less than 200W when running full out. And this is the wattage for a complete PC, with an overclocked Core i7-4770K at the helm.

With such energy efficiency available, is there a real need to invest in expensive, high-wattage power supplies? Perhaps not, as companies are now focussing on mainstream PSUs at lower price points.

An example of such thinking is with firms such as Xilence, a German-Chinese outfit specialising in value-conscious cooling. Recently purchased by Listan, the parent company of premium manufacturer be quiet!, Xilence is looking for greater exposure in Europe.
