I was thinking of running dual ati HD 7990s and looks like they both need 4 8pin PCIe power connectors in total, my PSU have them 4x 6+2PCIe power connectors.
So I was asking since mostly it shows that to run both 7990s in crossfire I'd have to have a PSU that's atleast 850W, but my PSU has the needed connectors.
so I'm basically double checking if I can have both cards without having to upgrade my PSU, as basically there's nothing over 750W that you can buy over the shelf, you'd have to custom order it or you'd have to buy it online, so I'm checking before I have to go through a lot of hassle on this
for my build I currently have:
CPU: core i7-3770 (no overclocking)
MB : Z77X-D3H
RAM: 4 DDR3 1600 MHz Kingston Xtreme blu
HDD: 2x WD velociraptor 10,000 RPM 600GB (RAID 0) on sata 6Gb/s
1x Green caviar 7,200 RPM 250 GB (non RAID) on sata 3Gb/s
fans (all are 120mm) : 6x Coolermaster LED fans
1x coolermaster standard fan (came with the case)
Optical: 1x DVD/CD burner on sata 1.5 Gb/s
PSU: Cooler Master GX 750W 80%+ Bronze
and I only have 2 USB (keyboard and Mouse) ports used at all times, I usually connect one more USB 3.0 external HDD and maybe one more USB 2.0 external HDD
that's all the information I have to help you calculate the power consumption
