I'm running 4x 5830 with a 650w TX650 v2...really
It is running at 100% load but is stable

Sweet. Should be able to squeeze enough juice out of my 800w Corsair GS800 for four 5830's then
I wouldn't quit before costs exceed profits. but you can't know in advance when/if that happens because price of bitcoins can double in several months and future difficulty rises % are unknown..
your electricity cost is pretty low, here in europe we pay 2-3 times as much in some countries - so you have a big advantage compared to miners with much higher electricity bills for same results

Hey guys, I've been mining 24x7 for the last month and a half at about ~ 1207.00 MH/s with 4 x5830's and an 850Watt Supply. My power cost here is 8.5 cents/kWh. With these inevitable complexity increases when do you think I should call it quits?
Yeah that sounds more like it to me.

As I said above, I'm running 4 5830s, two 850W PSUs, 2 CPUs, 2 Motherboards, an LCD Display, and an aux fan. I'm pulling 810W for everything from the wall.
An 850W PSU will run 4 5830s, a single CPU, and RAM, no problem at all.

I ran 4x 5830 on a 850w with no problem, Only pulled 708w from the wall.
"No way a 800w will handle 4x5830
5830s take up 188w each about, OC'd they can take up 250w
Even 3 will be cutting it close OC'd but will be alright so as long as you aren't running anything else high power.
For 4 I would get at least a 1000w PSU. I'd go with a 1200w just to have more headroom personally."
188w is the MAX TDP, not the actual power consumption. When you downclock the memory, each of my cards consumes only ~175w, leaving ~150 on my 850w to power everything else (more than enough).

Hi,
But OP says they have 4 x 5830's OC'd with an 850w psu which is why I want to know OP's full spec...
I'm not 100% sure but I think 800 wats might initially sustain 4 5830's but power supplies do degrade over time so after running 24/7 for awhile I'm sure it wont be able to handle it.
Depends on the quality and brand.
The higher series Corsair, Seasonic and Silverstone PSU's practically last forever even at high load due to the very long-aged components under the hood, unless you drive over it with a bulldozer.
The "downside" is that they cost $200-$300, more than some casual users' entire rigs.

Hey, Whats the full spec on your rig? I have two 5830's right now and was thinking of adding another two into my pci-e 1x slots, using pci-e extension cables and four Molex to pci-e power adapters. But I'm worried that my 800w Corsair PSU might not be able to pump out enough juice for that.
Everything else in my rig is pretty low power, sempron 140, 2gb ram, low power hard drive etc.
This just tells you. Do not keep your mining rig in a room with ac. Electricity bill will make you cry. During winter(depends where you live), if you only have electrical heating, you might be able to heat your house with mining rigs and thus get the power for free".
FWIW: 4 5830s, all the trimmings on 2 mobos, plus additional fan, all in at 810W full bore.
$2.50 / day in costs
$12.50/ day in revenue
$10 / day in profit
I'll be mining for a while

My guess is difficulty will outpaced by price increases in the long term
haha I posted something about seasonal mining elsewhere. In the summer you have to pay for cooling, but in the winter mining rigs end up subsidizing your heating costs 
Not only do you have to pay for cooling, but in most states the kWH charges are HIGHER in the summer than than the winter. This is true in Ohio (I have an additional per kWH Summer charge). So, you gain twice in efficiencies when mining in the winter: lower heating bills (sorta), and a lower kWH charge.
around 4 million difficulty with no further price increase is my cutoff point.
But I'll continue to mine through the winter even if we surpass that since I need the heat. Next summer I will shut down.

Indeed. I really wish I had found out about bitcoin a few months earlier, not only because I'd be flush with so many bitcoins I'd be swimmin in em, but because we had one of the most brutally cold winters in my states history riiiight before I turned my room into an oven (I literally warm my whole house when I ventilate the heat to home). Shame not all things work out as we might like them heh.
