It's seem like the solid polymer caps on front side modular PCB's not from Nichicon, I think it belongs to Unicon taiwan ( UPT series ).

Too little Elco and Solid Capacitors on secondary side cause poor ripple and hol up time. Must set new standart, Platinum and Titanium Level should not exceed 50mV on all output rail.

By looking at the components, The SF450 & SF600 share same platform, almost same components. Infact if we buy SF450, replace the primary capacitor with 420V, 470uF, and adding two AON6590 mosfet on secondary side, Woila, you get a SF600.

I must agree with turkey3_scratch, that Aris_Mp reviews much more informative and detail compare to jonnyguru. The only lack of Aris_Mp review i can find, that the review lack of joke . Btw, the APFC boost diode is 4A 600V, not 6A ( CREE C3D04060A )

It begin with the need for 850W PSUs, and one of my candidate is seasonic P860 Platinum. After googling, I find one review in http://www.overclockers.ru/lab/53761_2/Obzor_blokov_pitaniya_Seasonic_Platinum_860_i_Seasonic_Platinum_1000.html. But something bother me, that P860 used CREE C3D03060 (...

Always love to see PSU using NCC solid polymer doing good job in ripple surpression.

You are right, this is half bridge with LLC series resonant converter, nothing wrong with the primary capacitor.

this review said uses a half-bridge topology, I only see one main capacitor. half bridge usualy uses 2 main cap and 2 main switcher right ?

Using a bunch of KRG series capacitor for extra suppress ripple in Titanium PSU ? The Analogy : you want to build a super car, lets say Nissan GTR, but at the end you decide to use some cheap parts from Datsun on to your car, hahahaha. The Question is, How long this PSU will stay in titanium...
