    Our Verdict

    While the EVGA 750 G5 is competent, it's inferior to its predecessor, the 750 G3 and to competitors.

    https://www.tomshardware.com/reviews...pply,6337.html
    EVGA's 1000 G5 has acceptable performance, but the company's own G3 1000 is much quieter and more efficient for about the same price.
    If you want more info on them have a read through those reviews.

    In short, the Focus units have trouble with transient loads. Some of this has been mitigated by using cables with capacitors built into them, which will prevent the units just abruptly shutting down on you in a scenario where they shouldn't normally. On the other hand, the other main problem with transient loads is that some of them can cause excessive amounts of ripple to form and the for the unit to go way out of spec. This is not an issue in similarly priced units from the competition like Corsair's TX or RM/RMi/RMx units.

    Read the linked reviews above, but in short the G5 models are all a noticeable step down in terms of overall quality except maybe for general build quality. They're not worth the price premium they command when you can get cheaper units from other manufacturers that perform better or just as well.

    The transient problem it's not global, for example in aris reviews i found general good transient response and good ripple in test, he does thousand's of test.

    It is/was global, it just doesn't happen in Aris his tests. Even if he tests a lot, it's far from everything. He simply can't test everything. Also transient spikes can be much heavier than Aris his tests.

    Are you talking about the 3.3v tests?
    "The only downside we ran across during our performance testing was the 3.3V rail's response in our tough transient tests. This rail is only lightly used by modern systems."

    The also reported higher than normal noise at operating temps, which I do not like.

    No, Aris' test do not show the problems with out of spec ripple. Mostly because Aris' test don't put the same transient load on the units that they can experience from high power modern GPUs.

    Aris' tests are more just important to show the distinction between the G3 and G5 units.

    I was talking about the Tom's EVGA G5 testing.

    I mean it's not global because it don't happen with most of the GPU's, when it's happen it with spike up to x2.5 from atx max power (250W), to address the high ripple we need to test same senario with different PSUs, if you change the trip time for OCP you can avoid this. My point is, those GPUs got the blame too, another PSUs don't shut down that fact, if those PSUs got high ripple? We have to check this with the same computer with other PSU.

    The new focus gx act the same?
