Guys

I accepted that software measurement doesnt equal off the wall measurement when it comes to amd gpus although with my nvidia rig this seems to be the case.

Since I reach 1100w off the wall and my power supply is HP DPS1200 which should be 80Plus Platinum I wondered if the PSU isnt a little bit too less dimensioned and if I should get other PSUs. Maybe power consumption will also be lower since PSUs should tend to be more efficient when not working close to max?! lmkwyt

For max efficiency you shoud add a second PSU but at 90% usage you are still at around 92% efficiency vs 94% at 50% usage. Is the 2% gain on electricty usage really worth the added PSU ? Only your electricity cost and calculation over a year will tell you @ .15c/kw you will save only 27$ so it's not worth it.
However, if your electricity cost is higher and have several rigs it would be worth the additional cost
