    Arrow EVGA 450BT Review

    Now that the end of November fast approaches, a lot of people will be gearing up to build new computers for the holiday season. Some of these people might be looking for affordable, decent quality power supplies, and will be wondering if perhaps the EVGA 450BT 80 Plus Bronze unit might just be good enough to get the job done. Let's find out right now, shall we?

    Well, was kinda expected.
    Though I didn't expect the 3,3V rail to "fail" so hard.
    As that is regulated independently.
    The GR8323N is also one of the Supervisiors out of the Garbage Bin, because its only a copy of a PS223. And the Rest is the same in the Datasheet as the SITI PS223 as well...

    UVP:
    2,2V for 3,3V, 3,5V for +5V (here +/- 0,2V), and an abysmal 9V for +12V (+/- 0,5V).

    Why is it always so bad with most Supervisiors??

    At least the UVP values of a WT7527v are better but OVP is worse...
    And why is the PS224 used so rarely?? That one seem to have pretty good UVP...

    These days I don't because there are hardly any good ones.
    The ones you could consider decent can be counted with one hand as they are that rare (the mentioned Corsair CX, be quiet System Power 9/U9, maybe Xilence Performance A+ and in some regions Cooler Master Master Watt) and that's about it...

    The Problem is that most of them are too expensive to be considered.
    The Master Watt 550W is for example 56€ here in Germany - about the same as a 500W Pure Power 10 (11 is ~4,5€ more or so)...

    or a Cougar LX500 is 65€ - about the same as a 450W Bitfenix Formula...

    And most of the rest are just group regulated stuff like our all time favorite unit introduced back in 2010 - wich doesn't even feature OCP anywhere or OTP...


    The reason why Bronze has become so bad/useless is because Gold has become so cheap. And it just makes more sense to get an entry level gold unit over a mid range/upper level Bronze as they are similarly priced...

    Default What year or generation of processors/motherboards did 5v no longer cut it?

    What year or generation of processors/motherboards did 5v no longer cut it?

    Just a question for those who haven't been keeping close track for too many years.

    Although I am running an aged desktop. With an SSD transplant and adequate memory it still makes do on an i3-2120. If the power supply gets flaky would a unit like this be adequate ?

    +5V or -5V?

    +5V is still widely used. Memory, drives, chipset....

    Of course, CPUs haven't regulated from the +5V since the ATX12V 2.x was drawn up. Maybe about 10+ years ago?

    From Wikipedia:

    . . . ATX12V 2.x brought a very significant design change regarding power distribution. By analyzing the power demands of then-current PCs, it was determined that it would be much cheaper and more practical to power most PC components from 12 V rails, instead of from 3.3 V and 5 V rails.

    In particular, PCI Express expansion cards take much of their power from the 12 V rail (up to 5.5 A), while the older AGP graphics cards took only up to 1 A on 12 V and up to 6 A on 3.3 V. The CPU is also driven by a 12 V rail, while it was done by a 5 V rail on older PCs (before the Pentium 4).

    ATX12V 2.0

    ATX-450PNF by FSP Group

    The power demands of PCI Express were incorporated in ATX12V 2.0 (introduced in February 2003) . . .

    Sounds right. The Pentium 4 was the big move to the 12V rail, AMD following not too long after.

    Yep, AMD boards did it with the K8 (Opteron/Sempron/Athlon 64). The non-"64" Athlons were K7, and the boards for those still used 5V to generate VCore.

    It was even more than that, its close to 20 years.

    Rather precise, a week or so late, 18 years ago was Willamette (130nm or 0,13ยต) released - and the first Intel CPU to get bashed by people for it beeing shit/worse than the predecessor...

    Y'know, as I was doing a quick scan, I read '450BT' as "Hobbit." Strange. I can almost see it.
