That particular supply is only capable of 16.5 Amps which isn't enough.   Also, the price isn't even mentioned... what makes you think they are cheap?

Hi.

I very often read that it is wise to invest in very good power supply, due to their efficiency, durability, stability... Dogie had a nice review about good power supplies, https://bitcointalksearch.org/topic/guide-dogies-comprehensive-power-supply-analysis-486121

However, to introduce bitcoin mining to the masses, sometimes we must consider prices, noise and form factor (shape) over the other points mentioned above.

Is it possible to use cheap 12V DC power supplies like this one http://yqunique.com/products/s-201-singe-output-power-supply-ID584.html#.Vv0nnNWLSVM  or other similar instead of ATX alike power supplies?

Are their specifications too far away from standard ATX specifications that typical 12V ASIC miners will not work, or even worse they will burn down the miner? Here I have assumed that the power supply can give the necessary output.

If so, what is the minimum requirements a DC power supply must have to be able to drive the miners?

Comments from you will be highly appreciated.

Best regards,
aknnig
