Apevia TFX-PFC500W TFX 500W fits perfectly in a Lenovo ThinkCentre M72e small SFF desktop case using existing OEM motherboard (Xeon CPU installed) running a RTX 5050 video card. It doesn't have an official efficiency rating, but it boots up. The only 500watt tfx psu I could find for a good price. Giving 5 stars until i come across any issues.
I upgraded my Lenovo Intel i3 8100 90HV001MUS tower with an AMD Radeon w5500 card and knew going into it the OEM power supply would need to be upgraded. This is what I had to do to get this PSU to fit and function.You will need a ATX 24 pin to 10 pin adapter for the main connector. The two 4 pin to SATA power cables that are currently attached to the main board can be eliminated unless you plan to use the laptop style DVD-RW drive. If you do retain that cable.Only one of the 4 pin CPU cables from the new PSU will be used, and only 1 of them fits. It’s just barely long enough to snake under my

worked perfect although it was a little larger than the one i replaced had to leave top open on computer but that was ok
Great product! Lasted for a long time
I bought this Apevia 500W TFX power supply as a replacement for a failing unit, and while it powers my system without issues, it runs way too hot.Performance-wise, it does what it’s supposed to—my PC stays stable, and I haven’t noticed any voltage drops or crashes. However, after running for a while, the PSU casing gets so hot that it’s uncomfortable to touch for more than a second. The built-in fan doesn’t seem to move enough air to keep it cool, which makes me worried about long-term durability.If you have good airflow in your case, it might be fine, but in a compact setup, expect it to get
