So I was dedusting my whole family's computer (usually every 3-5 months). My mom's 340 watt PSU is failing. One of the two fans in the PSU unit has failed, so it is on borrowed time. I only noticed the PSU was in trouble cause when I was dedusting, the PSU was warm after being shut down for an hour+ at night. The computer is still useable, but I told my mom it is best to not turn it on until a new PSU is found. It is an Antec SP350 http://www.antec.com/specs/SP350_spe.html. I have a few spare new 430Watt Antec PSU, but it appears they are missing a connecter/wire. I need a PSU that has: http://i47.tinypic.com/2vsglj8.jpg Two wires (black and blue) http://i47.tinypic.com/4h8wpj.jpg At the end of the two wires, there is a black plug. The black plug has 3 holes (appears middle hole is empty, hence two wires) http://i48.tinypic.com/rlgcd0.jpg The plug goes into this part of the motherboard (the brown thingy) which has 4 pins, but seems 3 hole plug works. I need a PSU that has at least the same amount of 350 wattage that has that plug. Other plugs seems normal, 24pin, 4pin, 4 pin molars, and some sata. It seems I am having a hard time finding it. I did look at the antec specs for the SP350and I THINK, correct me if I am wrong, it is a 3 pin fan sensor. Again, correct me if I am wrong, I'd like to learn the term for it. Most item descriptions on online stores and box descriptions at brick and mortar stores dont list this 3 pin fan sensor. I am not sure if it is because most PSU in stores these days does not have that plug or what. Maybe I should just take the whole PSU to Fry's or some other brick and mortar store to find out >.<. My mom is getting cranky without her Korean drama >.>.
