It's not a bad PSU, but not a solid one either. It's basically a re-brand of "TX
" line for non-US countries (mainly Southern Europe).
But unlike high-quality "TX"es, "VS"es and "VX"es are assembled of the cheapest parts/components left. :\
It is fine as long as you keep it in a good shape, in a clean room and your case is standing on the table or anywhere higher than the floor level, since it can't handle dust well.
It's still much better than the lame "CX" line, so you can get it just fine. Just don't expect very much from it.
As about GPUs - just get HIS' HD 7770 iCooler
/Galaxy's GTX 650 Ti
and you'll be absolutely fine.
