Transient Response
20% Load – 20ms
| Voltage | Before | After | Change | Pass/Fail |
| 12V | 12.108V | 11.927V | 1.50% | Pass |
| 5V | 5.074V | 4.977V | 1.92% | Pass |
| 3.3V | 3.305V | 3.174V | 3.97% | Pass |
| 5VSB | 5.053V | 4.990V | 1.26% | Pass |
50% Load -20ms
| Voltage | Before | After | Change | Pass/Fail |
| 12V | 12.138V | 12.046V | 0.75% | Pass |
| 5V | 5.060V | 4.977V | 1.65% | Pass |
| 3.3V | 3.298V | 3.157V | 4.27% | Pass |
| 5VSB | 5.030V | 4.990V | 0.80% | Pass |
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!

Would the 750W version perform similarly? (in theory)
yes
Can you please tell me the difference between this model and original one (without II) since the adata xpg core reactor without II is a lot cheaper here..? Thanks
Hi, which one would you recommend between this Core Reactor II, FSP hydro G Pro, Montech Titan Gold or Thermaltake PF3 850w?
Thankyou in advance
Core Reactor II or FSP hydro G Pro,
Hi thankyou for replying, is the new Core Reactor fan still noisy?
Are there other better PSU than those two?
Can you mention few of them?
Thanks a lot!
Please look in my best PSU’s article to find the less noisy in this category. I have them all there.
Best overall for 230V still are these three?
Super Flower Leadex VII XG 850W, Cooler master V850i and NZXT C850 Gold?
Those might be better than the XPG right?
Hi crmaris
I am seeing that it is a very good PSU for the price, what do you think about buying it to use with a 4070TiSuper and an R7 7800X3D? 850W
It will be fine!
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.
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.
