The RS850 EMBA is a powerful 850-W ATX12V/EPS12V 2.2 power supply for high-end computers. The only item we miss is a hardware power switch.

Price differences of up to 50% can be pleasant if you live in the United States or in Canada, where prices for these high-end power supplies are low. But customers in France or the United Kingdom will certainly not be happy as they also have to pay a much higher value-added tax compared to U.S. sales tax. Even Germany, where we've been finding moderate prices, is expensive.
