So I was looking at getting the Antec P280 for my new rig and a friend mentioned that a bottom mounted PSU would suck more dust since dust settles and it would be sucked up from beneath the case. I searched the forums and haven't really seen dust as a topic of discussion when it comes to top vs bottom mounted PSUs. Anyone have some thoughts on this?
Bottom mounted PSUs are the newer design and provide better all around case airflow, a lower center of gravity, cleaner wiring, and my preferred configuration. Most cases will have an easily accesible filter and those that don't typically use an upsidedown PSU with the fan drawing air from inside the case. Your friend probably has an older case and is rationalizing.
I'm aware the P280 has a filter. I was just curious if anyone has experienced any issues with bottom mounted PSUs. Thanks for your replies. I figure the lack of complaints on bottom mounted PSUs and dust is a good thing.
Based on how much dust collects in top-mounted PSUs anyway, I would say this is not an issue. Dust gets pulled wherever the airflow is headed. I have never had any more problems with dust in bottom-mounted than top-mounted PSUs since I began using them.
