I don't know yet, I am waiting for our power meter to arrive to do some calculations. We are running a 1350W Enermax unit, which supposedly is capable of 4 x 290's (though I've not tried it yet). So by that rationale, we are drawing somewhere between 900-1000w of juice.

When our power meter arrives I will post up the numbers and work out what in real terms our power costs are.

cheers mate

depending on what your numbers are it might help me get to the next level.

watching this with keen eyes

good luck guys/gals

Power meters finally ordered, finding them in stock was a pain. They'll be arriving Monday

Hi,

I'm running 5x 290 non x's, 2 are elpdia on a different comp and 3 are hynix on another comp.

The hynix I've gotten @ 472k# for a few days stable before I switched back to multipool, but the elpdia I keep running into stability problems after a day. The wattage on the hynix's I remember being a little bit lower (NMT 10-15 watts) than I usually run regular cgminer. .which runs at 1110w with no undervolting (hynix cards running at 943k#), 92.5% efficient at that load, and 80w on the wattmeter side used by the system with no cards (cpu, mobo, peripherals). So after converting i'm seeing a usage of about 317.58w per hynix card. Using killawatt to measure wattages btw.

Decided to run vertminer while I was responding, so when running it on my hynix 290 non x rig @473k#, I'm seeing 1100 +/- 6watts . . so about 314.5w/hynix 290 on the dc side of the psu. . .about 1.501 k#/watt

Do you know if the cards you're running were elpdia or hynix? I'd like to switch the elpdia rig over to vertcoin but don't want to be tempted into an hour or two of messing w/ configs again and restarting the rig 20-30 times.

I think the first batch of cards we had must be elpida, because the 2nd batch of three GB 290's (exactly the same model purchased a week apart, on an identically specced rig) are getting 450 kh/s which some say makes them likely to be hynix cards. I've not looked into to much becuase both rigs are running so reliably.
