I confirm that power increase a lot after update.

I'm currently using Crimson ReLive Edition 17.7.1, my watt has been about ~870w, after update power shot up to anywhere from 1000w to 1300w.

Then I tried to downgrade to 17.7.2, watt did not decrease, that got me worry that something is wrong, since 17.7.2 is most recent stable version.

But after downgrade again to 17.7.1, my watt is stable again about ~870w.

So 17.7.2 and the blockchain beta version both eat away lot of power.
