Hi guys,

I wanted to up the voltage a little on my rails for my antec true550. Right now its reading 11.8, 4.9 and 3.23 on the voltmeter (not bios) and I think this is kinda low for the true550 since all I have is 2500+barton, abit nf7-s, 1x dvd-r drive, 2x raptors in raid0 and thats it. I read that I have to adjust the pots in the psu but can anyone point me to a guide or give me some instructions. Where are the pots in the psu, which direction and how much should I turn them to get like 12.1, 5.1, and 3.4 volts on my rails?

I don't have a TruePower, only a SmartPower, but there aren't any pots in it, must some precision resistors. They're of a different color than the regular 5% tolerance resistors and have an extra color band on them. Also the color band at the end is either brown (1% tolerance) or red (2%) instead of the usual gold (5%). So to adjust the voltages you have to find the right resistor and jumper it with a much larger value resistor to trim the voltage. It could be easier to start out with a 10-20 turn pot rated for 50 times the resistance, making sure that it's initially set for full resistance. But why bother adjusting voltages that are off by only 2%? Why move the voltage sense wires to the other side of the ATX connector? The sense wires are paired up with other wires but are often thinner, and sometimes for the +3.3V they're brown instead of the usual orange. I think TruePowers also have a sense wire for the +5V because my SmartPower was designed for one but it was left off. When I added it, the voltage at the mobo consistently increased almost 0.2%.
