Ordered one the other day, can't wait until it shows up. I am almost at 2GH/s now. Do you guys think it's safe to run three of these on a 750w Single Rail PSU? I used this http://bakkap.free.fr/Misc/wCalc.html and I figured each will need around 200 watts to run.

EDIT: I ordered the 5830 Xtreme version.

I'm running 10 5830s across two power supplies and the system draws just over 1500 watts. Have a damn hard time achieving greater than 2 MH/W with these inefficient cards Undecided

yes, if it's a good 750w psu (and if it's built for mining and doesn't have all shitloads of unnecessary peripherals)..   they use more like 150w or so

you also arent losing .50c a day in equipment value, like you would if you were using 7970's.

can't really imagine this being much of an issue unless you pay more than 20-30c per kwh, and if that's true, you shouldnt be mining at all

Dacentec, best deals for US dedicated servers. They regularly restock $20-$25 Opterons with 8-16GB RAM & 2x1-2TB HDD's (ofc, usually lots of other good stuff to choose from).  I did a Serverbear benchmark of one of my $20/mo Opteron (June last year), it's here.  Have had about a half dozen different servers with Dacentec, & none have failed to sustain at least 40MB/s (burst higher). My favorite is a 12-month rent-to-own ZT Systems 2XL5520 16GB 2x2TB SATA for $40/month (got lucky with the 'off-brand', haven't seen a RTO 2xL5520 for under $50/mo since -- at least for monthly contracts).  wholesaleinternet.com has some ancient 2-core intel CPUs @ $10/mo sometimes (I got an Intel Core 2 6300 @ 1.86GHz, with a 250GB HDD with 46000 hours on it, LOL. $20 @ Dacentec is much better, if you can grab one). joesdatacenter.com (same location as Wholesale Internet) also occasionally has specials (or if you don't want to wait, it has an AMD Opteron 170 @ $16/mo).

If your MH/W starts to become a problem you can always start looking into undervolting the cards, i've gone on my 5xxx based mining setup from around 6,1 GH/s and 1,9ish MH/W last summer down to 4,7 GH/s and 3.1 MH/W without changing any equipment. Was pretty much forced into it by my high power costs (0,18$/KWh, silly sweden Sad then again it kept me warm during the winter! ). Most cards are running at 0.95V while i've got a few random cards that can only do 1,038V  and 1,06V due to being non ref cards. On average the 58xx cards can handle around 700 Mhz at 0.95 and the 5770 ive got can do 750ish. Just goes to show what you can do with the 5xxx cards as long as they support undervolting.

Might also add that i'm running 80+ bronze PSUs atm so I could even increase my MH/W further. Long live 5xxx cards! Grin

Mine looked brand new as well. The sata to 6 pin connectors were a nice touch as well. The one issue I had was that my 11.04 live CD refused to function properly with it. There was really bad artifacting and the mouse pointer wouldn't display. I have it running under windows now and at 1000/170 is pulling 316 mh/sec.

Got mine today. Running it at 950/300 308MH/s. Going to push it to 1000/300 for a hopeful 325+MH/s later today. Stock voltage on everything (v1.163) with BAMT.
