    What can you say about a power supply, it either works great or its a dud. Kind of all or none.

    This is the second time I lost power to the computer. Once again, the power supply replacement with a higher wattage that fit what I had in a tower fixed the issue. I had upgraded the RAM memory from 4 to 12 Gbytes and I heard that it taxes the power supply energy. Higher than 400W power supply was also bigger in size. I will have to research what it would take to make it fit, but for now 400 Watt from 250W will do.

    I needed a fresh power supply for a recycled Dell PC I picked up. This one fit, has the same wiring configuration as the OEM PS, with a larger fan. Powered it up and everything energized. Quiet and steady. Instant gratification and another older PC went back to work.
