To be completely honest, the 750ti only uses 90 or so watts, some of them don't even have a 6 pin connector, Nvidia states that 300watts for the entire system. I would say he would be fine to run a 750ti off that PSU, I don't recommend that you run the PSU for long, I'd get the 750ti stick it in and good to go and upgrade the PSU in the near future. But I would not get anything higher than a 750ti or a GTX 950.
Then crossfire would be impossible right? As the AMD crossfire required another AMD Radeon graphics?

The A4 can not be crossfired unfortunately, I would avoid the R7 240 if you can, its only marginally better than the HD6450 and that card can't really play anything at or above 720p, even at 720 some games will not even play on the R7 240.
I would suggest an R7 260/260x or an R7 360/360x, but I stand behind the GTX 750ti as it will perform much better than all of them options I mentioned. If you're really tight on a budget, don't be afraid to look around on eBay, just make sure the seller is trustworthy.
I wouldn't suggest getting anything stronger than them cards, them A4 APU's are pretty low end, unless you do plan on upgrading everything then get as fast of a video card that you can so you could use it in another build.
