I hope this will help you make a good choice for your PC? It fit well in my Dell Optiplex 390 SFF Desktop PC.

I have Dell Optiplex 3010 and just got it in the mail and its shorter than the original one. Is it the wrong one?

Well i have a dell computer also i cannot tell now which number but this yeechung power supply fitted very good in my computer and works up to now.

i have a optiplex 7010. the power supply model # is L250ED-00. is this power supply compatible?

hi,pls order from this link https://www.amazon.com/dp/B072BX5GCQ it Compatible with Dell OptiPlex 390 790 960 990 3010 7010 9010 SFF Small Form Factor Systems Only

What are the measurements of the power supply (lxhxw)?

As I stated in my video, the measurements should be 7" l x 3-3/8"h x 2-3/4"w [max]. At the fan cage it will be 2-7/8" w [max]. I hope this will help any one looking to get a proper fit for their PC.
