Hey guys. I am looking at getting a new rig together and am brand new to the idea of SLI or CrossFire. I'm looking at the possibility of going for a quad crossfire setup using a set of Gigabyte Radeon 7770 OCs. The problem I am seeing here is the rated load on the PSU is massive - a whopping 400W each card. That means that with the CPU (AMD 8-Core 8150 @ 150W) I am sitting at 1850W power requirement already, without taking into consideration the watercooled aftermarket cooler and 1 x 140mm and 2 x 200mm fans in the new case.
Am I looking at this wrong, or is there some way around this that I am not seeing? I cannot see any PSU on the market over around 1500-1600W.
I think I have found the answer from google (took a while though lol).
Is this the minimum power supply to run each card? A benchtest I found on a website mentioned it uses 85-90W under full load, so an 850 watt PSU would run this fine in consideration with my other power requirements.
