Seasonic FOCUS PLUS PSUs Encounter GPU Compatibility Issues
It has been confirmed by Seasonic that their FOCUS PLUS power supplies are experiencing potential conflict with a select number of graphics cards. In regards to NVIDIA, the compatibility issue is currently limited to the ASUS GeForce GTX 970 STRIX. In limited instances, this particular graphics card can encounter a black screen under heavy load. Testing by Seasonic has determined that the issue is caused by higher than normal ripple when the GPU is heavily stressed. They also determined that solving the problem simply required using modified PCIe cables that feature enhanced shielding.
When it comes to AMD GPUs things are a bit more problematic. Both of AMD's Vega 56 and Vega 64 series of graphics cards with serial numbers before January 2018, can experience system shutdowns when paired with a FOCUS PLUS power supply. The issue is caused by higher than normal peak current being emitted by these graphics cards when under heavy load. This results in the power supply's internal protection safety being triggered. Considering Seasonic's popularity the fact these power supplies are encountering problems is likely going to be a hit to their brand image. At least they are stepping up to the plate having admitted to the problem while also investigating the root causes. They are also encouraging anyone that is encountering issues to contact them for assistance.
