I wouldn't try it. First, its a raidmax. They aren't known for great PSUs. Second, can you see in the pics that little red switch in the back? That means it has no PFC, which says its of an older design. Last, looking at the label you have no way of knowing how much power is really available on the 12V rails. You can't just add those two 24A numbers together. The source feeding them might not be able to supply 24A to both rails at the same time. The GTX460 while better then the other GTX cards needs more power then the 88/9800GT. I wouldn't try to run them on an older PSU.
