Personally I prefer semi-modular PSUs, where the 24 pin cable and the EPS cable are already mounted.
In a fully modular PSU, the hard plastic connectors for both of those cables intrude in to the space a bit in a tight build, whereas in the semi-modulars the cables are already mounted and are more flexible (within reason) in the PSU mounting space.

The RM850e features a compact 140mm depth, which leaves extra clearance for modular cables in tight mATX or compact ATX cases.

Thanks for posting this OP ... if I understand correctly since Best Buy mentions it's a "ATX 3.1" power supply I think it's a "B" rating on the power supply list
I think the biggest fail point on these PSU units is the fan. When I built my last PC I replaced the stock PSU fan with a high end Noctua fan that cost almost half the price of the PSU.
