    Default EVGA 450 BT PSU Review: Amazing Value At $25 @ Tom's Hardware

    https://www.tomshardware.com/reviews...-psu,5605.html

    Cheap power supplies rarely earn recommendations because they're often ticking time bombs. But the allure of a low price tag tempts the value-oriented among us. Normally, EVGA's 450 BT sells for $45. But from time to time, you'll find it on sale for $25. While that sounds too good to be true for a capable 450W PSU, we're here to tell you that this model does deserve consideration for its satisfactory efficiency, good ripple suppression, tight load regulation, and ability to keep its rails within the ATX specification's tolerances.

    I can't say I would recommend this unit. With the slight increase in cost to get something like the CX450, means I really can't see the point of a product like this. I understand there are folks who will buy and recommend this thing in droves but if you can't afford the $40-50 USD for a PSU then you probably shouldn't be building the system.

    Here in mexico it is significantly cheaper than any other decent units

    And I'd like to know why you wouldn't buy it

    sure it's got thin wire gauge and comes from an outdated platform but it has most protections and performs well enough for a basic system

    UVP seems rather useless. 9V for +12V, 3,5V for +5V and 2,2V nominal for +3,3V.
    That looks pretty bad...

    Corsair's CX450 and CX450M are often down to $25 so I fail to see the point of this unit...

    Graphs of the CX and CXm prices:

    Edit: 30c is also quite low, would certainly cause some issues where I live in the summer.

    But that doesn't make the PSU bad, at least to me and most people. There is so much more to a power supply than that.

    In the US it's a different story. As I said, price is too close to a unit like the CX450.

    All of the negative points in the review, put in comparison to the price of the unit versus others on the market. I would rather buy a more robust and modern design for any build I'm repairing or creating. I also have more faith in CWTs build consistency than what we've seen out of SuperFlower or whomever they are contracting the building of these particular units out to.

    But remember the CX450 is usually $25 with a rebate, the EVGA 450BT is straight up $25.

    At the moment, but that's not it's normal price. It's MSRP is $45 USD vs the CX450's $50 USD MSRP.



    At $25 they're probably selling the unit way below cost which makes me question EVGA's long term plans in the market. A warranty means nothing if the company goes belly up and a very low end build like this does not inspire confidence.

    I think people sometimes forget how much PSUs have advanced in the recent years.

    For example here on 2010, this thing used to cost 20$:

    No line filtering, the heatsinks are a joke, the primary diodes are a joke (the ones that are not used on 115V operation are even smaller), only one cap for each rail, the secondary diodes are a joke (A single F16C20C is supposed move both 12V rails, which btw are completely fake, not even separated by current sense resistors).

    Don't think so, once they were selling it for 10$.
