Corsair RM650x vs RM750x

[soadfan]

Help me pick the psu between 650 and 750
after a small research and tons of reviews and tests I stopped with corsair's rmx series. 650 is a bit more silent but it goes for $105, on the other side 750 is cheaper - $99 but it's a bit louder then 650.

my system is
7700k (not overclocked) + aio liquid cooling nzxt kraken x62
asus strix gtx 1080
4x8GB of ram 3200mhz
ssd + hdd
120 and 140 mm case fans and rgb light strips inside and outside the case

both power supplies will be able to power your system, i'd recommend getting the 750w one 1- for future proofing like sli or overclocking, 2- it's only louder when on full load which won't really happen with your system

I won't go sli, maybe upgrade to 1080 ti or the next generation once it would be released
650 avg noise is 13 dBa // 750 - 18 dBa not a big difference, but max load noise level 20 for 650 and around 30 for 750

my priority is silent operation

then i don't see a problem with oing with the 650 even tho it won't hit that max load noise.
