The transient response is good on all rails but 3.3V, where voltage drops below 3.2V in both tests. It is still a “pass,” but I don’t want to see values below 3.2V when the transient load is applied.
Transient Response ATX v3.0 Tests
The PSU passes all ATX v3.0 transient response tests.
The 12V rail’s performance is pretty good!

Hi crmaris, is this one better then the first core reactor? Price difference is big.
If you don’t care for ATX v3.0 and the 12VHPWR cable, you can go to the first version.
Hi crmaris.
After buying this power supply, I decided to test it with a tester from Aliexpress. When the tester is turned on, it starts beeping and Power Good flashes with a reading of 130.
All other indicators are normal.
Can you tell me if this is a factory defect or can I use this power supply?
P.S. I checked the tester on my old Deepcool PQ750M power supply. There it works without beeping and PG blinking.
You can use the PSU. These cheap testers are for basic stuff only.
Thank you, for your reply.
