It seems that the r630 has 450w psu's and 750w psu's. I'm curious if I can get away with 450w's if i want to run a pair of e5 2680 v4, which is a 120w cpu. There will be a pair of ssd's for the OS, and a single dual port 10gb sfp+ card. I searched hard and couldn't' find much info.

It should work, I believe worst case is the PSU become non-redundant if the power draw exceeds the load needed.
2x 130W CPUs + 20W NIC + 50W Mainboard&PERC + 2x 10W SSD and 7x7=50W for FANs puts you at 400W plus 3W/8GB of memory. That's the absolute max.
At 90%+ load you get around 90% (up to 92%) efficiency out of the 495W PSU. Thus, the 495W PSU tops out at around 450W fully loaded. You should be good, so long as you don't add big PCIe cards or disks. Barely.
When in doubt, use the "Power capping" function of the servers BIOS.

Efficiency has to do with AC/DC conversion, not DC output capacity. A 495W power supply can output 495W no matter how efficient or inefficient it may be. In this case, at full load, you'd be drawing 550W at the wall, assuming 90% efficiency.
