    Thanks for this complete review.

    But I think this review fails to catch the point that makes this PSU unique: its depth is only 140mm.

    Very few PSUs are able to provide 750W with such shallow depth, and no one does with such a good quality. This is a very rare feat. Cases with little space and most mini-ITX build can benefit from this PSU, I think this should be mentioned.

    Corsair RM-X, with >160mm is the main opponent thorough the review. Although It's fair to compare both PSU's, but we should mention what those 20mm extra do for, example, quiet operation. Corsair RM-X is no contender in this... "space" (no pun intended).

    Nay, I don't consider CWT to be the same tier as Seasonic or Superflower. At this price, I rather go for Seasonic. If XPG decides to use Flextronics or Delta, then I am on!!

    Here's one interesting thing i found about this PSU;
    TH review claims it to have 10 years of warranty
    Official site says it only has 3 years of warranty, link: http://shop.xpg.com/xpg-core-reactor-atx-power-supply-750w-fully-modular/Moreover, official site doesn't list it's specs either. Just a wall of text as a description. Hard to read description with light grey lettering on white background.

    That's an odd/shady sales site that is not secured. The info from xpg.com shows 10 years and the specs.

    On my end, that linked page doesn't exist.

    Uh-Oh! Not Found

    You’re in the middle of nowhere. The page you requested either was moved or doesn’t exist.

    What you can do:

    Go back Home page
    Contact to me if you believe this happened in error

    Also, when going to xpg.com, then selecting XPG -> Official Store, you'll land on the same store i linked in my reply. So, it is legit.

    Btw, on xpg.com, i could not find any listing of PSUs. There's plenty of other hardware listed there, but no PSUs.

    On the site under the XPG drop down choose products(not store) , then pc components on the page that comes up you can select PSU.
