GTX 770 SLI on MSI Z87-G45

[MrHeda]

I got my setup around 2 years ago and Im considering buying another Asus GTX 770 into SLI.
I´ve got some questions about compatibility with those 2 cards , the mobo and PSU Im probably going to buy.
Im planning on getting this PSU : EVGA SuperNOVA 850 G2
Motherboard I currently have : MSI Z87-G45
GPUs : 2x Asus GTX 770 2gb
My questions are,
Is that motherboard able to handle 2 Asus GTX 770s?
Is the PSU sufficent for 2 gtx 770s?
Do I need any special SLI bridge?

Thank you in advance. Sorry for those noob questions but im not really good at this stuff.

I would advise against going SLI 2gb 770s, though, you may find that the 2gb vram is a limit before the extra power can be much more use.
