Hmmm, right so, I'll have to look at an upgraded power supply down the line. As I say its a DVR chassis so there is tonnes of connectors for hdd's. there are actually 4 Hdd's in there. I'll only use the SSD OS drive and remove the others so that will free up my power connectors.

I'll get one card running and after a while expand with an extra card, risers and upgraded power supply. Any recommendations on the power supply?

Thanks Guys.
