Sorry I had burned your party. But finding a PSU which has 2 real 12V Rails is like winning in Lotto.

This 500Watt PSU for example only has a 16Amp rail. So one normal Gridseed miner already maxes it out :-( .

This feed focus on the heavy overclocking of those blades and that's why I call out to be very careful and do your math twice before you cause an fire. This is why I just recommend it to check twice. Also if you do your math just for LAB giggles 500Watt on pure 12V can only do 41AMP MAX but this is LAB condition. Most PSU's like the one above doesn't even get close to is. Also most PSU have a cheap cables which can't take a lot of load even the CE specs tell you differently, but that's a reason why MADE in CHINA is not MADE in USA or GERMANY. As I said earlier we did overclock with hardware mod's here which cause a much higher draw from the PSU so that's why I called it out just to be safe. Because the last thing you want is a house on Fire.
If you followed a bit my hardware mod's which do ramp Gridseeds for less than 10$ USD up from normal 600-800 up to close to 1100Hz. so you get a very nice and safe 3.3-3.6 MHz per Blade out without busting it's limit's all the way to the MAX.

Well then i guess i won the lottery, doing a simple route trace on that psu show 2 12 volt rails going to 2 seprate overcurrent protection circuits. Also worth mentioning this PSU isn't one of those scary PSUs that burn your motherboard after a month of use, its a mid-range PSU with very good component and PCB quality for its price.

sure would be nice if you could share specs of the unit and price so others could benefit from it too.
