Update: 2x working Singles (~60GH each), 2x dead BFL-supplied PSUs.

You can see an example of the dead PSU on the left side of this picture (the PSU is on the left, the miner on the right):

Had to purchase third party PSUs at Fry's, and fashion wires out of a child's toy, but the miners are happily mining.

Jeff, when you've ordered them (singles)?

Or just buy a proper PSU with PCIe connectors on it ......... like is in almost every desktop computer now-a-days

That's what I did -- but modern ATX often requires shorting a pin, to turn on the PSU.

See http://www.techpowerup.com/articles/other/22

This kind of devices are often gets hot if plugged in for a long time. Paperclip doesn't.
So follow your wishes, don't burn your house down

Or you could just call the manufacturer and tell them you received a defective product and would like a replacement.

There is very little current flowing through the signal line on a PSU - you won't be burning anything down by jumping it with a paper clip.

I somehow got paperclip with plastic coating.

I call them twisty ties. They come as accessories on loaves of bread.

If you're not handy then you can just buy one. http://www.pccasegear.com/index.php?main_page=product_info&cPath=19_183&products_id=7787

I got one at Fry's for a couple of dollars once.
