Seasonic manufactures the higher quality PSUs for Corsair and MANY other vendors. The HX series is one of them. Seasonic is considered the premier maker of PSUs by many PC enthusiasts. So it's very surprising that their PSUs are possibly causing such a horrible problem.
nice.
HashFast will be supplying Seasonic PSU's as stock in the BJ's and Sierra's.
