So I have checked all over the internet for a review on these 2 fairly new power supplies, putting them up against each other.
Those 2 power supplies being:
Corsair rm650x
Corsair CX650(grey label)

I'm aware the grey label is a lot better than the old models, and since it's new, there aren't many comparisons containing them, which is why I'm here. I hope you guys can help me choose, since the CX is about £56, and the rm650x is about £100. I can buy either one, but I'm skeptical that the difference in quality isn't so significant and worth the extra £44.
I'm not really bothered about modularity, however it would be nice since I got a cable mod voucher.
I'm also getting an overkill(ish) power supply for future proofing, since I've had enough of seeing my psu as a limitation.

Specs:
GPU: GALAX EXOC GTX 970
CPU: Ryzen 5 1400 (gonna overclock to 3.9ghz which is stable at 1.3v)
Mobo: MSI b350 tomahawk
Current PSU: XFX TS 430w (you can see why I need to upgrade)
8GB 2133mhz hyperX fury DDR4
250gb samsung 850 evo (sata)
1tb Seagate barracuda (games)

If these power supplies aren't really good at all, I would appreciate it very much if some pros could point out a fantastic 650w+ power supply for less than £100 in the U.K.


I hope you can help. Thanks in advance

well as you stated the rm650x is a way better PSU than the CX I can give you all the info I have gathered I prefer the EVGA model
PSU Tier list tier 1-2 are good for gaming
http://www.tomshardware.co.uk/forum/id-2547993/psu-tier-list.html

I would recommend an EVGA SuperNova Gold G2 / or new G3 /GS / GQ, Platinum P2 / PS, or Titanium T2 or a Seasonic M12-II Evo or S12-II
GOOD PSU EVGA is a B2, G2, G3, P2, GS, PS, or T2. Avoid the EVGA B1 and G1 series/ I bought a EVGA 750watt G3 with 7year garentee

Please avoid that tier list, it's filled with flaws, That Seasonic S12ii is mediocre, worse than the Corsair CX grey label. Also, those psu calculators overestimate, best just to look at reviews using similar GPU + CPU.

I was looking to buy off amazon since I have a £10 voucher and free prime next day delivery
But which one is more worth my money? The RMx or cx? is the difference in quality significant?

I've gone with the be quiet! straight power 600w cm power supply, and this thread did help. Thanks a lot for your help guys! really appreciate it!

I do plan on buying better, more power hungry parts in the future, and I see it would be a lot better to no longer worry about my power supply. Also only £15-20 more for an extra 100w is a good deal imo.

thanks though!

That Be Quiet doesn't have 100watts more and isn't at the same level of quality as thise 550watt psu's i linked and series you asked about.It has about 26watts more in total on the +12V rails.
The Be Quiet has also four +12V rails so beware that if you want to use a gtx 1080 ti you still might,and probably will,need both pcie cables to power that gpu.
