I cannot find a competent technical review of the power supply. Therefore, I do not have a basis for a valid opinion.
Ultra was famous for two things. First, they introduced modular power supplies. Second, they had a reputation for bad power supplies. That has changed. Ultra did try to improve the quality of their power supplies. A few of their new models are very good. Most are average and a some are still bad.
Here's some recent reviews from the same company but note that you can't judge any PSU by the quality of another from the same manufacturer. If i saw 3 bad reviews, i'd frget them buut 3 good reviews doesn't mean the 4th is good.... Silverstone PSU's for example have lot of 10.0's but also som e7's.
