Although its not clear which OEM thunder Series uses, Coolermaster as of now sticking with Seasonic and Enhance OEMS. Its Corsair which is now currently playing musical chairs with OEMs and actual designs, except the HX series and the AX series. Infact, RMA numbers for newer Corsair GS series, VS and certain TX models have increased over the period of months. I've been recommending Coolermaster GX, Seasonic S12II (with standard Tirupathi Enterprises disclaimer for people from Hyberabad till South) and Corsair HX/AX non i series.
The older GX450 weren't bad either. Its just that newer ones are better than the old ones, however CM did make a serious mistake of not highlighting the newer rev version.
Also, there has been an increase of people who have been recommending power supplies on the basis of brands. There have been people who have putting review links from those sites which don't do proper testing and actual test method. I would appreciate if such people cease and desist, or else I am afraid I'll be forced to point those people out in this thread inorder to protect people's hardwork in pushing this forum to the right direction.
Please don't take a forum back to the dark ages by such vague explanation. If people don't know what they're saying for the love of God atleast learn from multiple contents hosted online or else shut up!
