Narrowed it down to two options as I'm looking to future proof my psu
Seasonic SSR-650FX FOCUS Plus 650W 80+ Gold Fully Modular Power Supply
or
EVGA SuperNOVA GA Series 650W 80+ Gold Fully Modular Power Supply
Also Fully modular would help in tidying up the cables
There's not even a single review on the SuperNOVA GA series... that's a bad sign to start really. I wouldn't trust it unless I have a clear picture of the platform used, internal components and performance numbers.
I'd definitely get the Seasonic Focus FX over the EVGA, but... this has it's own problems aswell.
The older FX/FM revisions, compared to the newer GM/GX, will trigger OCP(over current protection) and shutdown or ripple a lot on GPUs that have high transients(really high power draw peaks). Fortunately that's not the case with the RTX 2060 as it's quite efficient when it comes to power draw, but with higher end card like the new RTX 3080 that might be an issue.
If the Focus GX/GM is available to you, I'll advise getting that instead.
What's the full system specifications of your build:
motherboard, CPU, GPU(we already know), RAM, PSU(we know as well).
