    Good transient response

  • +

    Long hold-up time

  • +

    Compatible with the alternative sleep mode

Reasons to avoid

    Expensive

    Not so tight load regulation at +12V

Why you can trust Tom's Hardware Our expert reviewers spend hours testing and comparing products and services so you can choose the best for you. Find out more about how we test.

The XPG Core Reactor 750 offers high performance, but doesn't beat the performance levels of either the Corsair RM750x and the more modern RM750. The Core Reactor 750 provides alternative sleep mode support and the super-high efficiency at light loads, but if you don't care about those things, he RM750x is a more affordable option. Compared to the RM750,  the XPG unit uses more reputable parts, but both PSUs promise at least 10 years of longevity and are backed by 10 year warranties.

    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.
