The VS is drastically better than the Mars.Is chieftec any good? I could get chieftec a90 80 plus gold for 65 euro.
I could get the VS650 for about 50€. These CX/M are pretty expensive.You need a decent PSU such as the Corsair CX/M (grey label).
Go for the Corsair CXOh, i can get corsair CX550 for 65Euro
but it kinda looks like grey and kinda white?
