With the HX1000 2017 Corsair
released a high-end power supply. There is a costly AC filtering stage, a high end fan, and
the massive use of Japanese capacitors, which come from Nippon Chemi Con and Nichicon and - amongst other parts -
add up to a great product. All the components mentioned comply with highest
standards and its hard to find other PC PSU's which are built according to similar
Furthermore this PSU is very reliable even if you plan to use it for a long time.
Compared to the predecessor Corsair decided to improve the cooling, thus we're finding quite a few aluminium fins, to which the different chips and MOSFETs have been attached. Should you be building a high-end system, then this is definitely a unit to consider. What's been a bit confusing to us is the information on the current protection in the case of flipping the multi rail switch. Corsair claims that the PCIe cables are backed by 40A each. Since there are four of them that would mean the unit could supply a total of 160A on the 12V rail but looking at the figures in the case of single 12V configuration there are "only" 83.3A. Since there is clearly a discrepancy we would like Corsair to explain this a little more in-depth on their website.
