    Hmm...



    Not if they're using 16g wire.
    With that price? I doubt they're using 16 AWG. Anyway, even with 16 AWG, I don't like it. Just kill those tricks!

    Considering this is rated at 30° C , I wouldn't put a VGA with two PCI-E connector on it. Even with separated cables.

    My guess is this PSU can do 350~400W at 50°C.
    It has to do with efficiency. If you rate this at 250 W @50° C, you could have trouble to reaching Bronze levels at 20% load, since 20% of 250 W is just 50 W. OTOH, 20% of 450 W = 90 W. Also, unfortunately many people don't care about temp ratings too, just power.

    And the 110-240 VAC on the badge looks suspect. If this is universal AC, it should be 100-240 VAC and be capable of doing 90 VAC.

    I will bet you dollars to donuts that the 30°C rating has nothing to do with efficiency and everything to do with power output capability.

    Likewise, the AC input "discrepancy" of 110V input. At lower input voltage, there's too much current at the "higher wattage" (i.e. the 30°C rating) and this makes the part fail. I'm quite sure the PSU supports 90V input >>IF<< the unit was only asked to put out 400W.

    I'm pretty sure I know what I'm talking about here.

    Well...for 20 bucks, its good.

    I mean, it seems way better than 99.9% of the other units at this price range and should be enough for basic systems with integrated graphics or something like Pentium G + GTX 1050.

    3Y warranty is interesting at this price range.

    So are you saying the PSU will catch fire or vreg will just get super crappy?

    Well, I should have said it has to do with efficiency too.

    Anyway, I don't like the 30° C rating too. I think it would be more honest to rate this at a lower power and higher temp than at a higher power with lower temp.

    430W is 30 USD. And until now, it looks much better.

    No marketing team would ever do that for a cheap PSU.

    I dont think its a bad product. Its a clever product.

    People that want a 20 USD power supply, will always get a 20 USD power supply.

    Period.

    So at least those consumers will have an half-decent unit to choose.

    Just look at the units selling on that price range...! Literally, time bombs.

    It's certainly going to be better than the other $20 stuff, I can guarantee it.
