Why did you waste your time testing then- you could have copied Anand's results and call it a day.
They got Zacate at 24/32, you got 28/36- it's obvious you don't care about 3-4 stinking watts- it's only 15% margin of error. Why don't we make it even easier and guess all the systems are somewhere below 50W.
And for the record, on the same page you linked Anand, unlike you, at least admits not having the right power supply: " I don’t have any pico PSUs or anything super efficient readily available so don’t expect any of the numbers to be particularly impressive, but what they are is comparable to one another. I hooked up each one of the systems I’d been using to the same PSU"
This is the difference, the huge exception, the ludicrous omission on your behalf- he used the same inefficient PSU for ALL systems. You didn't. His results confirm what I said- his ION idle is 35W, yours is 28W. Conclusion- his PSU is much more inefficient than the power brick that comes with Atom. In the same time his power supply is over 80% even at that low wattage- also much better than your OCZ POS.
If you tried to understand, you will see I'm not arguing about a few watts- my point was you can't compare your results, let alone I still think 700W with 25W load is ludicrous.
