So roughly around:
125W per card for CryptoNight @ 1950
150W per card for Etherium @ 44Mh
190W per card for Dual mining @ 44Mh / 1250Mh
125W per Cryptonight looks like the difference between the card idling but powered in the rig and mining.
What you really need is the diff between no card in the rig and mining.
My Vegas will pull ~30-35W just sitting there doing nothing so the real power usage is ~150-160W per card (@93% efficiency, pull from the wall). For comparison, by MB, CPU, memory and M2 sata disk pull about 25-30W when idling (!)
Please also specify if your numbers include the power supply efficiency or not (and that efficiency if they do).
I haven't seen real 125W pulled from the wall per card yet, unless you severely undervolt and underclock, but then bye bye 2K h/s
They were just rough calculations using the difference between idle and load. Yeah, in the end therewill be some overhead to add but thats gonna be constant. On a full rig im idlig 22.5 w a card
I mainy wanted to see the difference between the algos.
The psu was crap also. This weekend I am going to power one card completly of of a dedicated decent psu. Just have to find on with a decent efficiency urve @ 150w
Also going to test the rajintek morpheus on one.That bloody Delta fan alone can pull 28w at full rpm. Mostly hoping for lover leakage though.
