OP - Did you RMA your TX PSU? If you're still within the 5 year period, might as well take advantage of it. If I'm not mistaken, since TX V2 are now EOL, you'll probably get an RM or RMx as a replacement, which are excellent PSUs within its category.
Excellent, thanks Greybeard! I didnt even think of that, it still has 6 months left on the warrantly. I'll RMA it and sell the replacement as have bought the EVGA one now.
