Should be fine, budget CWT design like XPG Pylon.

They're talking about the old HX from 2010.

Do you see '-M' in there ? No, this one is would be (in the next revision, you can look up in the changelog) in low-priority subtier of tier C because that's CX-m 2021.

It's okay, but i'd totally recommend getting CX-F instead, 550W should be enough if it's a gaming build.

Thing is, it probably had the very same flaw as current Prime does - sensitivity to the backfeeding noise on 12V V-sense. They've just tinkered with it and somehow fixed, but didn't think of applying the same fix to Prime. And it's not actually clear if it fully fixed the issue for Focus in the first place but these few cases i've seen may be just a fluke.

Cable extensions ? I.e 0.7% off nominal ? That's an issue ?

It's High Power Aris has done reviews on Chieftec Polaris using it, but there's no telling if this one is similar components-wise.

Two somewhat different platforms used across wattage range, there are reviews on one and not on the other.

Huh, good to know. Not that it matters tho, it's probably not very quiet unit otherwise anyway. When we're getting some reviews ? Maybe shake that tree again a little bit ...

It would probably cry a little but if you can't get something better rn then it's fine.

One of the pins on 24-pin motherboard connector would have two wires coming out, one of them would be thinner (higher AWG gauge), you follow that wire back to PSU side of the cable and pull that pin out. To do that you'll need to push two tabs on sides of the terminal from the connecting side, get some thin tools or pieces of metal or thinner paper clips, insert them between the terminal and plastic housing and pull the wire. All that obviously with the PSU disconnected from the mains but technically you're working only with the cable so it detaching altogether would be easier anyway.

Yeah, it's just that it looks like Gigabyte has been selling both old an new revision simultaneously, we need to wait for GN to compare their units that blew-up with what Aris showed, because they had some past the manufacturing date this new revision starts from.

Old Seasonic Focus had the same problem with AMD Vega, they're very power hungry cards and introduce some noise back through sense wire to the PSU which causes the unexpected shutdown due to the flaw in PSU design. New nVidia Amperes are very similar in all that. Old Seasonic SnowSilent (and the new one too for that matter) apparently had the same issue, and in addition to that it's just an old unit overall. You can try to contact Seasonic about that if it still has live warranty.

Is it actual shutdown or restart ? If it's shutdown then can you power the PC back right away with the button on the case or not ? What are other PC parts ? Are you using cable extensions ? It's normal for older PSU.

It's just an effort of California government to increase standby efficiency of electronics sold there, it's not just about PSUs, there's a whole bunch of other appliances this spec is applied for.
