Personally, I'm shocked at your rating of the EVGA 1000W PSU. I also noticed that you didn't differentiate between the G2 and the P2.
I run a
1000W P2 myself. It actually has a 0db noise level at most loads, thanks to the eco switch on the back of it that only runs the fan when it's needed. Sure, the cost is higher than some others, but it's a lower rating than I'd expect. Also, the price of the 1300W has gone down a lot recently, and EVGA just released a 1200W P2.
The 10-year warranty doesn't seem to factor in to your calculations either.
Yes it does. The larger units simply don't compete in the rating due to their $/W.
I'm not saying it needs to have the highest rating, but I'm just saying it's a off.
For example, you rate the Corsair RM 1000W a 77.7. This unit has nearly identical specs to the 1000W EVGA, except it's less efficient, and has half the warranty. In light of this, I think the EVGA 1000W needs to be at least a 78. I imagine that this rating was done when the EVGA 100W was closer to the $300 range and never recalculated.
You should also differentiate between EVGA's gold and platinum series in your ratings.
