Seasonic versus bequiet
system will be a ryzen, likely 3000 series now with a 4 to be added in later
GFX will be a 580.
Seasonic go for a 54amp rails, bequiet have 4 raisl which can be combined using a button apparently?
I don't really understand the difference.

Is one 'better' for modern system?
Which would people pick?

I would pick a 650w gold for half those prices

If I had to pick between those 2 though I would go for the seasonic, 12 year vs 5 on the warranty.

Indeed, but there seems to be virtually no stock anywhere of anything at the mo.
I want quiet, what would people advise?
