this particular 500w psu 5K7J8 model has one negative user report.  it does not work based on report. #2 7050MT "I bought a 5K7J8 500w Delta amd it fit well. I connected one of the four pin white, and the six pin white plugs. The PC will not come on. The power button blinks amber twice. I tried the other white 4 pin; same thing. I put the old PSU back in and it fires right up" there are two positive user reports on another 500w psu model. MODEL H500EPM-00 UP/N: D500E005P Dell P/N: Y7R0X" vendor description is often mixed bag of misinformation so do not take it too seriously.
Greetings, I'm looking to upgrade the GPU in my Optiplex 3050 (i5 7th gen ) and realized I'd need to upgrade the PSU to do this. The prices on these things can cost more than I paid for the entire computer, but I came across this 500W genuine Dell part number 5K7J8 and thought it might be a suitable replacement. But I am getting some conflicting data. The eBay listing says it is for the 5080/7080, but searching the part number returns an Amazon listing which claims to be a suitable upgrade for the 3050.  Can anyone help me get some clarity on this? Thanks in advance for your insights.
