Re: ps50b451b2wxxu clicking not turning on

the cheap option is to buy from China and they will take a time to get to you, ebay is an option but will be the high cost one, I think a lot more then Ohm Supplies, but that is your call. The resistors I keep are SMD 1206 1/4w 5% and I use these on this type of job and power boards. I have also given you the wrong part number for U813 it is a IRS21856S this being 14pin the IRS21956S 20pin for U800 Flocko
