I just recently bios modded my five rx570's and happy with the 142.9MH/s but is pulling 950 watts from wall? I noticed when i was tweaking the cards i could not lower the clock settings at all or it would lose 1.5Mh/s!!!! Did not matter if i lower clock to 1250 or 1100 or in between same result for ever card that are mismatched brands. I was able to undervolt and seemed to help alittle, but iam pulling way to many watts you think ?


System:

H270A-Pro
G3920
250GB Sata HD
Evga 750 G2 gold PSU
Evga 600 Bronze PSU
Ver 006c risers

Cards:
X1 Sapphire Pulse 4Gb Elpida Hybrid 29.2 Mh's
X2 MSI Armor 4Gb Hynix hybrid 29.1 & 28.9 Mh's
X1 MSI Armor 8Gb Micron 27.8 Mh's
X1 Asus Strix Gaming 4Gb Hynix 28.7 Mh's

*All running stock clock core's 1268/1284/1300
*All undervolted 110 to 150
*All Memory OC to 2000 besides the micron likes 1900

I would like to get my MH/s the same but i need the watts down, any advice?
