not sure what SB is but the voltage readout for older motherboards wasnt that good. what is the 5v rail reading when you just power up the psu(aka not connected to the pc). if remember this psu came from OKwolf, im sure he checked it out first before sending it to you. if the 5v rail was really that low, then it wouldnt be powering up at all.
