Don't bother. It doesn't test the most important stuff anyway - ripple, transient response and protections, and even what it does - static load voltage regulation and timings are reportedly come with quite large measurement error. For RPM, i guess you can get a laser tachometer, don't forget to put a piece of reflective tape on one fan blade tho so measurement would be somewhat correct (there still would be some inaccuracy but that's fine really).

Unless you have a load tester and/or DSO and know how to use them, just a top-down shot of internals and a shot of solder side of the PCB. And if you can do close shots to identify markings, do ones of supervisor IC, bridge diode, APFC, primary and secondary side MOSFETs and DC-DC module if present. A shot of the fan label too. Basically, look at how Aris does it. Correct.

It was tiered there temporarily due to no reviews at the time and similarity to Sirfa #800 platform which had problematic OTP, now when there are review from Aris (from October actually) it will be moved to tier A and it looks like even marked gold.

Equal or greater than. Yes.

Thanks for sharing, i wasn't aware of that but as Jon said you'd better open a separate thread for better visibility for people with the same problem (although when your PSU refuses to work the first thing you should do is to ask support and you'll get that info anyway). Then you could still ping me or Luke.

Oh, i was wondering if QDion is actually FSP brand or not, since they don't seem to be using FSP as OEM exclusively.

No higher than tier C if it's indeed DC-DC but it's hard to rank it without any internal shots, looking through the fan grille it looks generic as shit.

Capacitors aren't the only thing that matters, it's a low quality unit, that's why it fails 100V burn-in.

Then it's a bad pick.

No, they claim 105°C main cap. As of RTX3080, i have no idea.

No one so far, it's just that an another buyer like you provided us with some internal shots and it's platform from some of more unknown OEMs (looks a tad like Zalman LX made by Hui Cheng, credit to @OrionFOTL IIRC) utilizing group regulated secondary topology which will all end-up in tier D unless there will be review of it showing <5% min to max voltage regulation under crossloads. About the magic smoke, it might not show it right away, or even down some years, a bad PSU today is not just about blowing up. Even if the unit has all basic protections functioning and doesn't blow up und

Tier D.

If it isn't plain sleeve bearing then it would likely end up in tier A.

Will be fixed in the next revision.

There is, just for that one case Luke mentioned above, but as i said, since there are very few reviews of their units in general, especially recent ones, i would rather assume that they still practice stuff like that than do on contrary, since when it comes to PSUs there are no presumption of innocence. I would still recommend some of their units if you can return them after you confirm visually that it isn't what it's supposed to be (or keep it if it is) but we're playing safe here in the tier list since it's supposed to be fool-proof.
