Looking for a New Modular PSU

[Flogger23m]

Looking for a modular PSU (or semi modular). Trying to keep the price down, but I am open to other suggestions. I currently have an Antec Earthwatts 650 (Green Edition). My main reason for upgrading is cable management. Although I don't want to loose any notable capability in my upgrade. Durability is important, as I want to keep it for 5-6 years.

My Specs:
GTX 1070 + Small OC
i5 4670K + Small OC
MSI Z-87 G43 Motherboard
16GB DDR3 (4x 4GB)
2x SATA SSD
1 SATA DVD/CD drive
1-3x SATA HDD
5x 120mm case fans
Numerous USB devices

Planned upgrades:
AMD Ryzen + possible OC
Future video card (don't plan on SLI/Crossfire)
M.2 SSD
More case fans?

What are my best options? On the lower end of the price spectrum, I found the following:

SeaSonic SSR-650RM 650W $80:

SeaSonic M12II 620 Bronze 620W $60:

Is the $80 SeaSonic worth the extra? Corsair & Antec options seem to be more expensive at the moment, but I am open to suggestions for particular models.

It depends on what you plan to do. If you are keeping everything at stock, the extra cost most likely isn't worth it. The G series might last longer, but I think it's doubtful it'll last 30% longer. If you are overclocking, the G series will deliver cleaner power that may or may not help your overclock. Since you are planning a small overclock, it probably won't have an effect.
