Classic power guzzler in standby mode: Office PC with budget power supply
Unsuspecting, unobtrusive and neat cheap plastic – this is how many online discounters offer their supposed bargains like sour beer. Dumping prices, savings in all corners – the greed wants to be served after all. What the customer does not see: some of them are installed in such cheap parts that you want to run away smoothly, once you hold the electronic misery in your own hands. This includes, of course, primarily the power supply – in this case, a Chinese popping frog, even labelled on his own company.
This is a “420” watt power supply from Hardwaremania24, as it was safely installed in hundreds in PCs. A look inside reveals a codegen clone with very inexpensive components. Apart from a fuse and a varistor, there are no protective measures. This power supply has a stand-by consumption that at almost 16 watts is twice as high as the normal consumption of our small netbook. This in turn leads to the entire housing heating up properly. We will add a test of this bollard to the planned article about the cheap upgrade of an office PC, because the whole thing was not really a thing of the fire service.
With a daily stand-by time of only 14 hours, this would result in a daily power consumption of completely unnecessary 226 Wh, which in 365 days totals 81.76 kWh. With a electricity price of approx. 22 cents/kWh quickly ayear 18 Euros come together. With an average service life of such PCs of 5 years, you can get 90 Euros – 1.5 times the cost of a small 80+ power supply with gold certification! In addition, during the usage time with higher efficiency, one would save almost the same amount again by lower consumption.
The arc of the CE mark, which we have extended in red, indicates a different letter position and thus China export instead of CE.
This small calculation alone proves the relevance and importance of the energy-saving directives. If you let yourself be driven by greed, always put on it at the end. Be it due to high stand-by consumption, low efficiency in operation, or an almost incalculable durability and safety of the operation. We again expressly advise against such offers.
