Will my psu be sufficient?

[Doileen]

Hi guys, I recently decided to build my own computer and I have a few questions, it was designed around a i5 2500k, here are the components:

I5 2500k oc'd to 4.5 ghz stable
Msi p67 gd53 motherboard
4gb corsair vengeance lp ram
Akasa venom 400cx heatsink with 2 viper fans in push pull
Ocz Zs series 650 w psu
Msi r6870 hawk gfx card.
500gb hdd
DVD/rw

Everything is running fine and my comp is completely stable, what I was wondering is would my psu be able to handle another r6870 in crossfire?

Also the gfx card used 2 x 6 pin power cables and my psu only has 2 of those, so if I wanted to crossfire how would I connect a second?

Thx alot for reading and I hope you can shed some light on this.

yes its enough and your card should have come with molex to pci connectors you can use that

Thanks, anyone else think it will be ok? I've been told otherwise because I have oc'd my CPU that it may not be enough power.

Thanks
