those are terrible specs. Extreme el-cheapo units.
30A x12v =360watts 12v on a 700watt power supply
36a x12v = 432watts 12v on a 1000 watt power supply.
My GS 600 produces 572 watts on the 12v line.
This is why you should only buy name brand PSU. Someone should regulate PSUs. This is the face of "false advertisement." I feel bad for the person who buys this because your not getting 700-1000w worth of power.... unless you like alot of 5v
