So my power supply that I was using for the miner dead on me and, now I don't know what is the recommended power supply I have a 650 watt power supply from my old gaming computer http://www.amazon.com/KENTEK-Black-120mm-Supply-EXPRESS/dp/B0083Y7JUY (http://www.amazon.com/KENTEK-Black-120mm-Supply-EXPRESS/dp/B0083Y7JUY)

Is this a good power supply to power the antminer s1 with out having hardware errors?

Not unless you underclock it pretty hard. Specs say that PSU has a 22A 12V rail (most of its juice is on 3.3V and 5V, so it was probably designed before Pentium 4 and such were common), which means a max power output of 264W on the 12V. It's probably coregulated with 5V, so no draw on the 5V and high draw on the 12V would probably slack your 12V rail; 264W is an optimistic estimate and it'd probably burst into flames about the time you actually drew that from it. An S1 at stock settings will want closer to 360W of 12V to operate. If your S1 is undervolted and underclocked all the way they'll run below 100W, but that's certainly not the default configuration.

The psu is not good. You should not use cheap psu since the miner will run 24hour.

That's an absolute garbage PSU. Best case it quietly dies without killing you, your family, or your hardware. Worst case it burns your house down, killing you, your family, and your pet goldfish. I wouldn't let that thing anywhere near electronics, much less plug it into anything. Might be useful as a paper weight, but then again it's probably too light.

You can't skimp out on power supplies, people. Especially with mining.

Yep, that's why folks like pmorici and I have been around making server-grade PSUs available to regular folks for the last year and some. For the cost of a junk ATX unit you can get a kilowatt of 80+ Gold capable of sustaining rated load indefinitely, with flexible cabling.

And I can't recommend you guys enough. I started with Seasonic ATX PSUs, discovered server PSUs and soldered my own wiring, and then you guys came along with your breakout boards and changed the game. I'm running your DPS2000 boards, and I couldn't be happier.

The only time I've ever had miners on an ATX supply was when I was testbenching ASICMiner Cubes last January or so. And smoked out one of the connectors. Server PSUs with high-quality cabling is hard to beat.

OK thank guys for telling me.

Im planing to buy this power supply is it a good power supply Rosewill LIGHTNING-1300 it provides 1296 watt on the 12v rail?

The Lightning is great, but depending on it's price you could probably do better.
