No the PSU has lots of space by itself but im talking about the graphics card which version should I buy if I want one that can fit in my caseyes, the RM750X is a very decent PSU. depending on your rig 750W is most likely overkill.
What the RM750x is not is small. it's a rather long PSU with 160mm. if that's an issue... Seasonic Focus GX is only 140mm long, as is the Antec High Current Gamer or the Corsair TXM Gold
