🔌 Li-Sun 240W Switching Power Supply for Dell Optiplex 3040 5040 7040 3650 3656 SFF (Part Number: THRJK 4GTN5 D7GX8 HGRMH 2P1RD H62JR 3RK5T) - Reliable Replacement Power Supply for Optimal Performance Review

One morning my working Dell Optiplex 7040 would not turn on and the self test LED on the back would not go out. With helpful advice over the phone from two computer repair techs, helpful step-by-step breakdown instructions in YouTube videos, and prompt delivery of this power supply, I was able to swap out the power supply and get it back to normal. a few days before my employer sent me a new computer.

Schedule a replacement. There is a design flaw as PCs using this power supply have a history of power supply failures. The OEM power supply failed so I bought this one which failed about 4 months after purchase. My computer is always connected to a UPS, so it's not a power quality issue. The good thing is that the seller honored the 12 month guarantee and sent me a new one even though it took 10 days to ship and receive it.

Old computer wouldn't start. The LED on the power supply is off. I vacuumed the PSU by blowing out the dust with compressed air. Nothing helped. I looked up the part number on the site and found this. The photos showed that the part was very similar to my broken part. The difference was that this power supply has an input of 115 while the dead power supply could be changed between 110 and 220. I needed 110 so there was no problem. Note: The wiring to the motherboard according to the original…

My Dell PC's power supply died. It is an exact replacement and took less than 5 minutes to install. A simple chip fix to get it working again.

I was in urgent need of a replacement for my chiropractic main computer. I am very happy that I found this seller. I was able to install the replacement the next morning and they were back up and running within 15-20 minutes of walking in the door with the replacement. Perfect replacement for the original AC adapter that was cut off due to a power surge.

I had a Dell Inspiron with a bad PSU and bought this and it was perfect for the job. I was concerned that it's more of a regular power supply, but for me it just snapped into place, so it's definitely Dell specific. The computer turned back on and I gave it back to the customer to do the work required. It's been about 2 weeks now and the customer hasn't complained (and they'll trust me) so I'll call this a winner and recommend to others!

Works as a replacement for a small Dell Inspiron 3250 desktop although it is not listed. Replaced the 180W unit with this one. HAPPY HAPPY HAPPY ! I also received it within 2 days.
