Some PSU can deliver more than what was it rated for. Not all energy will be use, some will be wasted as heat. The actual power consumption will be less than the amount of wattage pulled from the wall.
1380W? Really? It seems too high for two 290's, even with core clock at 1040MHz which I believe at stock voltage. Do you have anything else plugged in other than your PC?
ULPS stand for Ultra Low Power State. It only activated if you have Crossfire, meaning more than one GPU. ULPS put secondary GPU to low power state when not in use (it's like the GPU is turn off or sleep/standby). If you're overclocking, it's recommend to disable ULPS because it can prevent secondary GPU from overvolting which will effect stability.
An example, graph below show GPU2 in crossfire (overclocked) is still running at stock voltage when ULPS is still enabled.
Yeah think I figured it out! Drivers were not loaded correctly as the ULPS stopped a component from loading properly. So fixed that - kept it all at stock speeds and it's working quite well. Going to try and OC my CPU again now..
As for my system - it is:
2x 140mm fans
8x 120mm fans (some LED lighting)
1x 200mm fan
1x H110 water pump
2x Gigabyte 290 Windforces
1x 4670k OC
2x 4GB G Skill Trident X 2400mhz
4x USB devices
1x DVDRW drive
2x Storage HDD
So yea the draw is relevant to the numbers being pulled! I have a 80% Gold1 000w PSU so in theory my max pc load according to my gauge should be 1250 from the wall - is that how it works?? Something still tells me I need a 1200w PSU...
