    Probably only lasts 3 years unless one is willing to recap it. I tend to prefer to recap old supplies (and oil the fan) rather than buy new; have a house full of old equipment that works just fine.

    Well, it could be great for basic builds. In Spain you don't get a PSU with PFC for $13

    I vaguely recall researching these when they first went on sale and finding another reputable site for whom one of the models in this line blew up under load testing.

    Rosewill ARC units haven't had a formal review, at least not one I could find on the internet.

    The 450, 550, & 650w units are ATNG's ATM-B platform with a bog standard 120mm sleeve bearing fan and some Teapo SC caps.
    The Nexus RX-6500 is based on the same design and ignoring a DOA unit they should be fine replacements to any office PC or older gaming rig.

    The 750w unit is based on a different platform (ATA-B) though; but I don't know of any comparable reviews.

    There isn't a formal review of the Arc, and I was thinking of another ATNG Rosewill that had more problems. At any rate, here's one of the same platform: https://www.kitguru.net/components/p...m-650w-review/

    One thing I find missing in many power supply reviews is the switching frequency (typically 50 kHz - 1 MHz); the higher the frequency the better the power to weight ratio and the easier things are on the secondary caps. But one will suffer the skin effect at high frequencies, and need Litz wire for the transformers, which I have seen used.

    I have no problem with 85C capacitors on the input; some people argue that 105C units have higher ESR and so potentially lower life. It is the output side that has a lot of capacitor failures, but the move to higher frequencies is easing the internal heating they suffer (from ripple current).
