Hey guys. Im have close to zero experience with mining but for some reason i decided to give mining a try. Today i got my hands on 5x block erupter blades (v2 i believe). I still have to purchase psu for them, i dont have a backplane so i would go the other way around with the 4pin connectors. Theres a promotion going on in a local store that sells Cooler Master Silent Pro M2, 520W for about 60euro including free shipping, it has 5x 4 Pin connector but unfortunately only one 12v rail. I guess it woulnd be suffecient to power all 5 of the blades?  I have another older psu that is sitting vacant in my room, i belive it can power 1 of the blades. Can you please suggest a reliabe psu? I want to order it asap. I guess there would be lots of other question, but i think thats the most important one so far. Thanks in advance.
