## Questions & Answers

**Q: would this fit in a sgpc k39 case?**
A: We referenced the k39 case's Amazon page and found that the case can house a PSU that is 17*80*40cm or smaller. Our PSU is 150 x 81.5x 40.5mm, which is 15 x 8.15 x 4.05cm so according to this info, it should fit. You can check with the case company, and give out our PSU dimensions to make sure, just to be safe.

**Q: Will this fit in a hp m01-f0134 replacing a 180w power supply?**
A: From what I can tell of that model, I would say yes.  At least by physical dimensions.  One thing of which to be mindful is that this PSU has a 24-pin connection to the motherboard.  So, you should verify what type of connection your motherboard supports - I had to buy an adapter because my MB had a 14-pin connector.

**Q: Does this unit's fan push air to the unit or exhaust it out?**
A: Pushes air into the unit

**Q: Looking to swap 40mm fan with Noctua but they only make 10mm and 20mm deep fans in this size. Do I go with the 10mm and then... tape around the gaps?**
A: Get the Delta AFB0412HB. It is 40mmx15mm and quieter than stock fan. Not as quiet as Noctua, but def quieter and meets spec for this PSU
