Does not make noise like another one I tried
I'm still running a 2007 Dell Core2Duo machine. Don't laugh. It still does almost everything I want it to from photo editing to audio file editing and MS Office. It of course can't run Windows 11, so I'm stuck on Windows 10 until October 2026 after I pay MS $30 for providing updates for one additional year. So, I wanted to keep this thing running for another two years. But I was already on my 2nd power supply that died. I purchased one a few months ago to "fix it" but it was awful. Made a terrible racket noise from the fan motor. I used it a few months but couldn't stand it any longer. I took a chance and bought this one. It works great and is quiet, just like I wanted. I know there are several marketers selling these PS. All I can tell you is that this one met my expectations precisely. Now I can use this old machine in peace. Very recommended.

Make sure to tag all the connections
The power supply fit perfectly into my systems unit. The cables were the appropriate length, Removal and replacement took me about 10 minutes.

Power on
This replaced a dell power supply that was, itself a dell power supply from back when this machine was still under warranty. Both of the PSUs this replaced quickly started buzzing. This unit has been installed for about 1 month now and has been running 24/7 and hasn't made a peep. Power is steady the few times I've checked it, so no complaints on this unit. The shipping was super fast, too.

Working power supply
The power supply was not the exact model as advertised but a compatible unit. It works fine but it didnt have the proper power for my DVD drive.

Perfect replacement part
Worked perfectly - had the computer up and running again in under 15 minutes. OEM was a great plus - everything fit perfectly.

Not new but functional
It wasnt new as advertised. It's a rebuild & shows signs of wear. The fan chatters like the one I'm replacing. It functions as a power supply.

Exactly as advertised.
This was the exact part for my computer. I had my desktop up and running in about 15 minutes. I believe the part was refurbished, but you couldn't tell. It looked factory new.

ottimo acquisto
ottimo acquisto, installato su un dell server poweredge t105 e funziona perfettamente, i cavi sono anche migliori dei precedenti perché tagliati a misura

Almost a perfect buy.
Bought two. Both works fine but the one of the ps fans is making a noise with it hitting the case. No big deal since I had the spare and likely just trim the fan blade of the noisy one when needed.
