Another GPX : https://www.techpowerup.com/review/chieftronic-powerup-850-w/

So it reboots, not shuts down completely and sometimes doesn't even post ? Doesn't look like a PSU issue to me, what are your settings on CPU ?

Yeah, i've missed the imgur album with teardown pics, it's definitely not CWT, it's Helly or whatever OEM manufactures 1st Player Steampunk PSUs.

Nothing to do with the PSU.

A few others do, from Sirfa too IIRC. It's a gimmick if you ask me.

Another one btw : https://quasarzone.com/bbs/qc_qsz/views/596364
Looks like a new platform from Sirfa.

Eh, not much need for that, i'd just keep the warranty.

Yeah, you're right, i thought i've seen a third choke there. And no, on a closer look, i don't recognize this exact platform, it's close to oldest S12 <=430W tho (non 80+ rated one, SS-[W]HB) which...

ChengX 85°C caps in a SFX PSU ? I'd pass, even though most caps on the secondary are polymer ...

Yeah, this old-ass platform was Bronze, double-forward, double mag amp, i doubt it can do 80+ Gold but it doesn't matter much anyway, it's still outdated, had pass unless it's hella cheap and will be...

So it is UVP after all.

What wattage ?
Also, they recommend 750W PSU for R5 + RTX3070 and 1.3kW PRIME for RTX3090 with R9, LMAO. 'Just buy our maximum wattage stuff, please ...' Too bad they still don't have 1.6kW model,...

I mean, Jon himself said that they weren't able to get any RTX3080/3090 to test them, but maybe that's someone from different division ...

Eh, it didn't work in my case (Zen 2 and early UEFI...

Transients ? At idle ?
This is no PSU issue. Keep UEFI up-to-date, disable XMP and tweak RAM settings manually.
And although i'd probably replace 7 years old PSU by now if it was me, Seasonic...

Ah, that's why i couldn't open it, i just assumed that it was my provider acting up again, nice to know.

It's fine, go for it if it's cheaper.

There are a lot of units they tested that don't have reviews published on. Some of them have full reports public (at Cybenetics), most don't, S12III among them sadly.

Yeah, but if you look at exhaust grille shots, they're completely different.

They're probably completely different. If you look at back grille shots for them on SF site they look very different. GX Pro has a capacitor in the centre of the PCB like on Leadex platform, while HX...

I'm the only one who can't access the site ?

It's MEIC too, just as most Gigabyte units including their recent disaster of P-GM, but there are no comprehensive reviews on it altogether. Should be okay for 55$ probably but i wouldn't use it in a...

I don't see them either.

Same company, MEIC Power it seems. Completely different stuff, AP-GM wasn't that bad, there were some ripple issues in Aris review and a good amount of user feedback mentioning terrible coil whine so...
