  1. 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

  2. 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

      1. 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!

          1. 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?

  3. 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

  4. 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.
