The transient response at 12V should be lower in the 20% load test. The deviations on the other rails are low, but the 3.3V rail drops below 3.2V because of its low nominal voltage, which is an easy fix for CWT.
Transient Response ATX v3.1 Tests
The PSU passes all ATX v3.1 transient response tests, but the 3.3V rail drops low in the 180% and 200% load tests.
The 12V rail drops lower in these tests than similar spec offerings. Still, it is way above the lowest limit allowed by the ATX v3.1 spec.

I just order this, but i cant get the Seasonic out of my head, is it worth another 20 usd over this one? Im very casual gamer and will be going in a 13600+4070 combo hopefully
Nice review, i buy this PSU(130 euro) and is amazing.
Hi, on page 8 “protections” it says 1046w for the OPP, but how is that 123% of 750w ? It would be 123% for a 850W unit, but for a 750W unit 1046W is 139.5%. If the OPP is set at 123%, then shouldn’t that be 922.5W ?
yeah the 850W unit’s table was there. Fixed now, thanks!
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!
