After reaching the 1500W milestone, PSU developers have taken a break. Whether it is because they cannot put more power into the dimensions of a regular computer power supply or because even their marketing departments have come to realize the uselessness of even higher wattages, but I can see only a few 1500W models and no models with higher wattage selling freely today.

Some time ago I tested Thermaltake’s 1200 and 1500W units (based on the same platform) and was left disappointed. The low stability of their output voltages prevented me from getting the full specified output power from them. However, later on I tried a Corsair HX1000W, which was also based on a similar platform, and had much better results. So, I have a suspicion that these high-wattage PSUs were not quite good in the first batch but improved later.

Today I will be able to check my suspicions by testing two products: Xigmatek “No Rules Power” NRP-HC1501 and Thermaltake Toughpower 1500A-01 W0171. Both have a wattage rating of 1500W.
