AnandTech has written a review of Xigmatek's new NRP-HC1001 1000W and NRP-HC1201 1200W power supply models. The firm also has a 1500W model but the reviewer says he passed on for this model as there isn't really a need for such a powerful model.
Xigmatek wants its power supplies to have a unique appearance to help them stand out from other companies. All of the shrink hoses and heatsinks inside are covered in orange, which looks pretty cool and contrasts with the green of the PCB. The housing is quite long for a normal ATX power supply, but the 1000W+ understandably needs more space than usual. The total length is 8”/20cm, which will cause problems with smaller PC cases. The weight also needs to be considered, as there have been some issues reported where the whole rear of the case has bent and distorted because of the weight of heavy power supplies. User’s with a thin plate, aluminum chassis should take this may experience difficulties.
Both models deliver adequate performance and have a competitive price tag.
