Total of 38A, just barely. I wouldn't bet on it though. I wasted a card once with a weak PSU. Under the slightest load I put on it, even a video, the PC would restart, the GPU was overheating and I didn't realise that it was the PSU's fault until I had to take the card back because the lack of power had damaged it.
Always get headroom when you choose your PSU, it is the last part that you would want to cheap out on.
