MSI Z87-G45 Motherboard or GIGABYTE GA-990FXA, 8GB 1600Mhz ram, 8GB USB Linux(BAMT?). 2x Milk crates.
290s 250W/12V=21Amps x6=126Amps
6x 290 @ 250W=1500W
2x 850W PSUs?
Powered risers on cards 4-6
From what I've read here, the 280x and the 290 consume the same amount of power 250-270Watts.
Any gain in PSU efficiency using a 220V outlet?
290 840Kh/$500=1.68Kh/$
280x 750Kh/$400=1.87Kh/$
https://litecoin.info/Mining_hardware_comparisonI've been running a single 290(stock 1 fan) 24/7 for a month now, getting 840Kh(1000/1500 OC) 79˚C 4500rpm in the garage(32˚F).
The better hashrate for slightly more $, seems to favor the 290s, but I can see how 2 fans are better than 1.
So should I get the 280x just because of cooling, having 2 fans instead of 1?
Anyone a reseller with Ingram Micro, Techdata, D&H? Are there prices any better than Pricewatch? Any other sources?
