Title: How much are you paying for each pcie slot?
Post by: shickenphoot on June 24, 2011, 09:14:17 PM
Just curious to see what people are paying for each of the pcie slots?
On my main computer that would be $750 each but its my 7 year old and I payed $1500 for it then.
My others are about $80.  Seems really high to me but I wonder what others are paying for each and how they getting it so low? And Why are some people paying way more?  I don't see how people buying 6990 for $750 and then adding $150 cost for each slot and still see that as economical. $900 for ~700 Mhash when I pay $380 for ~600 MHash and I still think that's I'm overpaying.

remember that a 1x with a extension is good enough, I see plenty of systems with 4 or 5 slots on an openair rig with a total cost (minus cards) of less than $250.  A semperon chip with last years motherboard and a 1K power supply and a supply of extensions and you are good to go for a 4x5870 system.

Wow $250 for five cards that how much i thought it should be. can you post the parts? That would be $30 less for each pci-e.  I didn't know about the pci-e extenders where do you put the cards?

hmm.. the lowest I can can find is about $410 which is $82 per pci-e

G.B. http://www.newegg.com/Product/Product.aspx?Item=N82E16813128487

5x ports $110

2x PCI Express Card Extender Cable PCI-E 1X Riser Adapter -- $9 Shipped

Intel Core-i3 Sandy Bridge dual core quad thread CPU $125 - $25 (see combo deals at bottom)

http://www.newegg.com/Product/Product.aspx?Item=N82E16819115078

110 + 18 + 100 + 20 (ram) / 5 = 49.6

I prefer Corsair, Antec, OCZ, or Enermax PSUs for longevity usually only $30-$40 on sale.

12v power is all that matters it is on the label.

Thanks for posting the list, saved me a trip to newegg and the change to buy something else I didn't need :)

The thing with mining is that it is all about the cards, everything else can be cheap.

Older motherboard with lots of PCIx1 or better, wattage processor & hdd, enough ram and you are good to go.  The less wattage your base system needs, the more that is available to the cards.

Do not under any circumstances skimp on cooling though.  Best I have seen is a channeled openbox with the extender cables out and away from the motherboard.  Each channel had its own fan (think shoebox with a fan at the end).  Cheap and cheesy and won't win any awards but the combination of being away from the case plus a lower ambient temp and its own dedicated fan = cool card.

Don't cheap out too much on the psu as well; you don't want a crappy $30 1200W psu blowing out, taking your $4000 worth of cards with it.
