## Questions & Answers

**Q: Will this work with the lenovo m93p sff?**
A: Yes, it should!  I have just installed one in my m83 sff box, which also uses a TFX PSU, and it is working fine.

Remember that you will need a 24 pin to 14 pin adapter to power the motherboard in these machines, as Lenovo used a non-standard connector.

**Q: does this work for 9010 dell optiplex DT? The motherboard is a matx.**
A: I have it installed on an Optiplex 990 DT on week 3 now. Can confirm it works well.

**Q: Will this work with dell optiplex 790 sff?**
A: If the motherboard has the right power plugs, it should work, otherwise you may need a conversion adapter to power the computer because some have proprietary connectors for their specific hardware

**Q: Can be installed in lenovo thinkcentre m920s sff ?**
A: Please check with Lenovo directly for compatibility questions. Our TX300 is a standard sized "TFX" form factor power supply. Also Lenovo appears to be using proprietary cable connections for power supply in their M920S, so even if it fits, the cables may not be compatible.
