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

Refurbished on eBay is $10 cheaper if you want to go that route. I did when they were $55 each, now $63.

Spend the extra $7 to get the Asrock Steel Legend SL-850G for $79.99. The corsair is rated B+ by SPL and the Asrock is rated A

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.
