Modded PC power supply for charging

[tc3_racer_001]

an internal short perhaps? carefully check all the wires u unsoldered/cut and taped/heatshrinked up to make sure they are not touching each other. u also need to put the green and brown wires from the mobo plug onto +5 and ground (PLEASE NOTE: I DONT KNOW WHICH ONE GOES TO WHICH OTHER CABLE SO MAKE SURE U CHECK FIRST AND ONLY USE ONE OR THE OTHER, NOT BOTH!)

so once you figure that out, (its on the net) then try again. if it doesnt work add a reasonably heavy (>1A) load on the 5v rail and it should work better.
