Ask the designer to see if the PSU is big enough to hold up for a few years. https://forums.geforce.com/default/topic/502292/ups-for-dual-gtx-950-39-s-sli-ups-is-under-rated-for-gtx-950-sli/?offset=6 noted 895 Watts and your PSU is 550.
Yes they have duals but 550 sounds light. Ask the machine's designer to step up and warrant it for a few years.
