Is there any consensus on a good Power supply to buy if you are running 40+ sticks.

I pulled an old 380w Raid Max out of my retired computer hardware box and have been running 43 block erupters and 2 usb fans. Seems like new ones on the low end are just not up to snuff. I realize it has something to do with the power going to the rails on new PSUs from reading through the forum, but my understanding of electronics is limited. Seems like a better idea to go digging through the garbage than online shopping at this point.
