Fits listed Optiplex SFF models only
It suits owners replacing a failed or missing power supply in the exact Optiplex SFF models named above. Builders working with other form factors, different Dell lines or non-Dell systems should look elsewhere because the connector layout and chassis dimensions are specific to these units.

Questions about this item
Will the 3.3 x 9 x 2.4 in unit fit my Optiplex 3040 SFF chassis?
Yes, those dimensions match the Dell B240NM-00 form factor used in the 3040, 3650, 3656, 5040 and 7040 SFF models.
What is the installation step people often miss when swapping the H62JR unit?
After sliding the supply in, you must press the blue release latch until it clicks; otherwise the 24‑pin connector will not seat fully.
How often should the internal fan on this 240 W supply be cleaned?
Blow dust from the intake vents every six to twelve months; the fan itself is not user-serviceable.
