A princípio esta fonte não suportaria placas de vídeo muito beberronas, pois seu rótulo nos mostra que temos múltiplos barramentos de 12V, três, para ser mais exato.
Mas segundo o teste feito no site JonnyGuru, esta fonte dispõe de apenas dois barramentos 12V sem circuito OCP, deixando claro que não há qualquer limitação contra sobrecorrente. Não sou especialista em eletrônica, mas creio que você possa colocar com segurança qualquer placa single GPU disponível atualmente.
Looking at the main PCB, we only see two points where 12V leads are soldered down. One labeled 12V1 and another labeled 12V2. For fun, I put a 30A load on the 8-pin EPS+12V connector. This should have tripped the PSU. It did not, which tells me that there is no OCP limiter set for this rail. I did the same with the ATX main connector and again the PSU did not trip.
Above is a close up shot of the PCB and where the 12V wires all solder down.
This demonstrates that if the two rails are in fact separate, there is no OCP (over current protection) on each rail. Outside of a few traces zig zagging across PCB, I couldn't find how even 12V1 and 12V2 are separate, but I'm going to give Seasonic (the OEM for the Corsair units) the benefit of the doubt and say that we seem to have two 12V rails here, neither with any kind of "limit" on them.
