Thank you for the detailed review and your time spent for testing the units.
I just bought this unit on Amazon during BlackFriday deal because of good result in your test.
Aris did PCCooler YS1200 basically same PCB parts & design of Seasonic GX/PX-1200 ?
U mean the “Same Platform” thing?
Don’t remember sorry. please check Cybenetics if there is parts description for both units there.
Thank you for all these PSUs reviews !
you are welcome!
