4 x sapphire 5850
rig draw 620W so my meter says..
That's a very efficient rig...can you give details - i.e. other hardware, what you are using to measure power, and how you have the cards tuned? I thought 4x5850s would draw about 600w alone. Thanks.
sure, I may have a very poor meter, not at all sure

i thought 620W is a bit low - I just bought the cheapest wattmeter i could find for time being, almost a bitcoin virgin @ <3weeks lurking
it's Velleman Wattmeter, EAN:5410329428518, I'd be interested what people's opinion of a reliable wattmeter is, will cost more than 15eur I expect
