Alternative PSU for BFL Single
October 27, 2013, 05:26:14 AM
#1
I recently swapped the PSU on my BFL Single 60 GH/s unit. Before I swapped it it would hash at around 57 GH/s, after I replaced it with a 1000w Corsair PSU (all I had) it began running a tad over 60.
Now that is not an issue however, I started to wonder since I replaced it with a 1000w PSU does that dictate the actual power draw out of the wall or is that simply what I assumed it was "the max power output"?
Any feedback would be appreciated.
Thank You

It's not going to draw 1000 watts at the wall unless you load it up with 3 singles. It's wall power draw depends totally on what is hooked up to it.

Exactly
Also,that PSU is not going give a decent effiency until its drawing about 80% of max,which would be 800 watts.Until then the effiency is going be poor

Would you be so kind as to elaborate further? I am assuming you are referring to overall cost of operation?

He's talking about PSU AC to DC conversion efficiency. Most power supplies are most efficient at 50% power load. (not 80%)

It's going to be at most 2% less efficient. Hardly a deal breaker.

4 singles here on a FSP 1000w 80+ gold, 965W at the wall.

Get a platinum power supply, you would save more energy in the long run....

These power supplies also have really poor power factor correction, which is why they run hot. Fortunately we pay for watts and not volt-amps, but still it's pathetic.
