Great deal! The stock power supplies are rated for 200watts and in turbo mode I was seeing 201watts in turbo. Isn’t this bad? I thought you’re supposed to leave a 20% buffer so that you’re not maxing out the psu?

I tested these units on a 750w psu as well and if you abide by the 80% rule, you’ll need higher than an 850w unit if you’re going to run more than two units.

I don’t recommend running these at max settings. I don’t live in a cold climate and these got really hot fast! 75C and the room was hot. I went from 12.5th/s in turbo @ 800watts to 14.5th/s at 1050watts for 4 units (two 750w psus). Each unit saw about 266wats at full speed.
