I was frustrated with my first PSU as it didn't do anything. I tried and tried and nothing. I sent it back and the new one connected and fired up the computer on the first try. So I went from sadness to joy. The return was easy also. Just took some time to show up as credit.

Unit works fine use this company fast delivery

My dad had purchased a refurbished Dell a while back and it lasted him for 7 years. However, dad isn't great at dusting (78 year old bachelor) and his old unit got gunked up. Found this replacement on Dell and installed it in about 15 minutes. He was back up and running in no time at all. Delivery was quicker than the original date suggested, even during the pandemic! Dad was extremely happy we got him up and running so fast.
