Hi Guys,

Currently I have:
1. Core i7 920 overclocked to 4.0Ghz
2. MSI Eclipse mobo with a Creative Xi-Fi sound card attached to a PCI slot
3. basic Zotac GTX 970 (core clock is increased to +160mhz)
4. 256GB Crucial MX100
5. 4TB Seagate HDD 5,900 rpm
6. Samsung DVD+R/RW drive

I plan to add another basic Zotac GTX 970, and increase the core clock to at least +160mhz, and probably one or two more high capacity hard drive (4TB or 3TB depending on the price) running at 5,400 or 7,200 rpm.

Would I need a 1000w PSU for that build or would an 850w PSU suffice?

Thank you
