I have the following system: i5 8400, MSI B360 Gaming Plus, 16GB of DDR4 (2x8), GTX1050 Ti, 4 case fans (3 of them powered at 5V and one from the MB), CM Hyper 212 Evo, 1 SSD, 1 HDD, 1 ODD. I need a new power supply because the actual one is dying. I will also get a new GPU (probably a GTX1660 Ti or RTX2060), and one or 2 more SSD's or HDD's. My current power supply is a Sirtec High Power 600W Bronze.
Which from the following should be OK for my system: Seasonic Focus GX, 80+ Gold, 550W or Super Flower SF-550F14MT, 550W 80+ Silver ?
