Any ETA on the pump and res? Also, is 500W really enough for heavily OCing a GPU and CPU?
nVidia overestimates power needs because they can't control and thus recommend an exact PSU for all of us to use, in addition to not knowing what our configurations are. In this case, no pun intended, EVGA gets to play OEM and by being in control they can make more specific guarantees. For instance, mini-ITX boards limit the types of CPUs and power phases limit how far they can be overclocked anyway. How far can you really push the graphics card given the space constraints for cooling air/water? It is not the PSU.
Besides, it isn't the wattage you should focus on, focus on the amperage from the 12v line since that is what the CPU, graphics cards, drives and fans use. The rest of the system doesn't use that much from the other voltages, so you can ignore them.
An all stock system of a i7-2600K (
93W) and a Titan (
250W) is 330W from 12v, or
27.5A. There isn't enough room for so many drives and fans in the chassis, while EVGA's 1U rackmount PSU has 40 Amps from 12v available. You can overclock both 30% (by power, not frequency) and still have room. Although it you put in Ivy/Haswell, you using less power per overclock, blah blah, I'm sure you may have figured that out by now.
