I just wonder how are you going to clean, while still keeping it under warranty, something that has a 12 year warranty.

I have an original Prime 650 (not Ultra) and would like to know specifically how they differ.

It would seem the Ultra is just a Prime, with a couple of meaningless upgrades. Is this true?

Yes, as we said above, the Ultra is an upgraded PRIME. Along with some minor tweaks to the design (Seasonic does not specify exactly what) the main difference is the longer 12-year warranty - I wouldn't call that meaningless. If you have an original PRIME you should be well served for many years to come.

They did specify it, when they released upgraded Ultra line. See:

Are the PSUs really that quiet? Basically not audible, quieter than the room? My computer's fan go at 450RPM and I have no HDDs to make spinning noises anymore.

Yes, they are very quiet. But sound/noise is subjective. Even though the SPL numbers are hard data different people respond differently to sound. To my ears, this PSU was very quiet - silent until the fan kicked in (no coil whine or electro-mechanical noise). The test lab is relatively cool and quiet (fairly constant 73 deg and 27 dBA) - to the point I opt to turn off the building A/C air handler during testing. Both the background temp and sound level will contribute to your experience of how loud a system is. Hope that helps answer your question.
