Going by some reviews on bit-tech, prime95 @ 4.9 draws about 221W, and gaming load on a 560ti is about 150ish, so let's say, with mb and other stuff, you may be pulling 400W total. so it should be ok. Just don't overclock your graphics card too much also, that will start causing some issues.
Although your posts are confusing, you say you havne't had a warning so far but at the end you say it will be a week before it arrives? Are you getting a replacement psu or ???
