    Hasn't Failed Me Yet, Always a Plus
  

*by C***Y on Reviewed in the United States on November 8, 2017*

After having a Thermaltake short out and fry components and another one arrive DOA in the same week I switched to Seasonic as my go to PSU for my builds. It's the only name I trust anymore. Having it be fully modular is well worth any additional cost, though I found the cost to be quite reasonable compared to other brands.

    This is the best bang for your buck PSU
  

*by D***N on Reviewed in the United States on July 19, 2017*

This is the best bang for your buck PSU.  I haven't had any problems with it and now-a-days all the PSU's go under heavy testing.  I always hear horror stories of RMA and shorting, but seasonic has always been a good company that I've never experiences problems with.  Definitely get this PSU if youre looking to build a budget computer
