$51 (with promo) and free shipping. 630 watt. Single 12V 50amp rail. I am running one of these for three underclocked 5830s. Should run two overclocked 5830s very well. Can't beat the price either.
You are welcome.
that is a wal-mart style product... there is a reason it is soo cheap.
I wouldn't buy, say, a Dynex to power a mining rig (tried that, it would restart every couple of days), but anything better should do just fine. Buying an overpriced PSU for mining is just buying insurance that you don't need. JMO. The important part is keeping it cool, as I learned when I killed a 750w Corsair with 3 5830's.
probably because the corsair is not rated to run at 100% of the 750w 24/7. the SeaSonics are rated to run at full wattage 24/7. Suit yourself.
I didn't want to wade in but I do think there is some wisdom here. These are machines that "need" to run 24/7 for you to expect to pay them off and make a profit. Spending a little more on one of the 3 core items in a mining rig (Motherboard, GPUs and PSU) is a wise investment over the long run. I tried a PC & Power Cooling PSU from a recommendation but in the future I will be using only Seasonic because of it being rated in a 24/7 environment. That is actually worth the extra $50 in the long run.
