Topic: Adding some mining cards to my rig... (Read 979 times)
thats a kingwin psu. I wouldnt trust its specs. if it were corsair, psp&c, seasonic, antec I would say its good as they are real world rated (actually underrated in most cases).
You could underclock the 2 extra cards you put in. Not the most efficient of ideas, but more streams running at a slightly lower speed is better than fewer running faster. Also this would generate less heat that you'd have to pump out.
According to my power monitor my entire Rig is using about 750-800W to produce 1.1GH/sec.
What power monitor are you using?
Some global monitor that I was sent by British Gas. I can turn everything off in the flat excluding the fridge, and then mesure my computer usage from that.
Depending on what cards you decide to add, I would consider upgrading to a better power supply. I certainly wouldn't trust that PSU to deliver 850w continuously 24/7, but it might be OK for pulling 850w continuously from the wall, giving you no more than about 700w out the other end at 80% efficiency. The PSU is one piece of gear that you don't want to skimp on or be too price conscious about. A better, more efficient PSU means lower power bills and is much less likely to end up frying your other components when you drive it hard.

I added 3 x 5850s into pretty much your entire setup... it currently uses around 800W of power and generates 1.1GH/sec.
Yikes... thats slightly disconcerting... 5850s use less power than 5830s and 6970s. :/

Yeah I've got plenty of lanes for it, I'm really just worrying about Watts.. but if a guy fit 2 6970s and a 5830? That's great news for me. Could you link me to where you saw that? 
looks like you can fit 3 cards in there at 16x and 2 more at 1x (get extenders). i've seen two 6970s and a 5830 run off 850W. my guess is you're ok.
So I right now have a regular, non mining rig. Just my day to day computer. That said, all I have is an 850W PSU in it, I was never expecting to pile 3+ cards in it. But now that I want to get into mining, I decided I might as well put some cards in my desktop to save money on another PSU for now.
My desktop right now has a Radeon 6970 (OC'd to 975Mhz getting 430MHash/s)
Also included in my desktop is an i7 2600k, a Seagate 7200RPM 1TB hard drive, an Asus P8P67 Deluxe Mobo, and 8gb RAM.
My entire setup: http://secure.newegg.com/WishList/PublicWishDetail.aspx?WishListNumber=15749245
I am wondering if its possible for me to put 2 Radeon 5830s into my desktop without trouble.
I did some basic math and it looks like my rig without graphics cards uses about 250W, a 6970 uses about 225W, and each 5830 uses about 200W. This rough math puts me right at 875W... over my limit. I am just wondering (hoping mostly) if maybe I did the math wrong and I indeed would be fine? Is there anyway to double check without going out and buying a Killawatt? I'd really appreciate it if someone could help me out.. maybe rerun the numbers or something.
Secondly, what would happen if I do go over the wattage? Will my PSU explode? Will my graphics cards burn up? Or will some things just simply not work, or the computer not turn on/randomly freeze?
