💡 Li-Sun L300PM-00: High-Quality 300W Power Supply for Dell Optiplex 7010, Inspiron 3847, Precision T1500 & More Review

My old power supply broke and I had to replace it because my 10 year old Dell Windows 7 computer contains 32 bit engineering software which is irreplaceable. Bought this power supply and am very happy with it. However, as other people have commented, I had to make some changes, which wasn't that hard. I had to cut a pigtail for the hard drive power cords from my old power supply and solder/shrink it to the new one to get to my dual hard drive. The power supply fits perfectly into the original…

I have a Dell Inspiron 580 which I received in 2010 and have had trouble starting over the years. I assumed it was the start button because the problem would appear for a few days and then go away for months. Then the computer died. I researched online and found that Dell had problems with the power adapter in some models in 2010 and 2011. I received this replacement power supply and it was perfect for a replacement. Same size and had all the necessary power cord connections. I had to look on…

The power supply fits and fits my Dell Studio 540, but I can't power both drives and CD at the same time. In the case of panes lying on top of each other, the distance between the connections is specified. On this PC there are 2 disks next to each other and the CD is in a separate area. So you have to use each of the two cables for each drive and you can't turn on the CD drive.

My wife's computer power supply started ringing like a chainsaw. I write music and the noise was unbearable. So I ordered these. Aside from the color marking on the stylus, assembly was easy. When he was picked up and taken back to the alcove, he fell silent. The next morning the car was turned on. The chainsaw was gone. Instead, it now sounds like a deranged killer hive! Not sure if I should return it or just order another one from another seller.

The thought of opening up a tower computer was no fun, but I can assure you almost everyone has the right PS (this is an Inspiron 3847 unit) easy and can install with minimal knowledge. Just unplug the current power cord, remove the side of the tower and take a picture of the four connection points, remove the screws (the latch is on the case where the cords come out of the old unit, push it just put it in) and hold it in place and reinsert the old unit. takes no more than 15 minutes. I don't…

I work with LF and VLF radios, and this part of the spectrum is already filled with bogus products from other cheap consumer electronics in a suburban area leading this one power supply from 200 kHz and above very many interference components. False signatures only change in frequency between PC on, idle and off. The only way to get rid of them is to turn off the computer. My original Dell power supply was very quiet, as were most other high quality switching power supplies. My guess is that…
