PSU recommendation for ASIC Block Eruptor cube

[krone9]

Hi all

Thanks to some help on here I got my first cube up and running but I'm only getting about 37% efficiency and a hash rate of 18GHs

Its currently running off a Corsair CX500 and I'm wondering if thats adequate for the job. What PSU would you recommend/are you getting great results with?

I'd like to get to 95% efficiency and 38+GHs clock speeds - any other things I can do?

thanks!

If you are only getting 18Ghs you likely have a loose heatsink or board.  See help info here https://bitcointalk.org/index.php?topic=307095.0

would I not see X's in the cube admin screen - if that were the case?

all are showing as zero's

I'll go through that thread(s) you linked to though - thanks!

Those cubes use about 220W low mode/330W overclocked from the wall. You'd think that the CX500 would be sufficient for one (and it's single 12V rail is @ 38A, which is plenty), but I keep seeing posts about people having issues with the CX series and these cubes.

I've run a single cube off of a TX650 with no issues, and two cubes at the same time off of a TX850M, again no issues. Whatever you decide to get, make sure the PSU has a single 12V rail that's rated for 50A or greater. Good to go.

I run 4 cubes on a single Corsair AX1200.  Aside from melting the ends of the power cords once a week it works great, averages 155Ghash.

Fail? You gotta be joking, right?

In response to your question... gonna let your picture be the answer. Hope your home owners/renters insurance is up to date.

I sold one the other week so the PSU is under 1300Watt load now.  Like I said, it worked fantastic for over a month, just ate a few cords from the drawer of cords.
