In seriousness to anyone wondering about this, I think the general consensus is that the G3 series is exceptional with the potential concern about the OPP protection being slow to kick in. So if you get a 550 W power supply and load it up to 800 W, it might not automatically shut down until it's way too hot.

Good idea, although I believe OTP is also a concern, no? @STRMfrmXMN @Stefan Payne @LienusLateTips

Yes, here is the information from Tom's review:

 

Protection Features

Check out our PSUs 101 article to learn more about PSU protection features. Our protection features evaluation methodology is described in detail here.

Protection Features
OCP	12V: 77.82A (143.8%), 11.069V 5V: 30.25A (137.5%), 5.15V 3.3V: 30.5A (127.1%), 3.23V 5VSB: 5A (166.67%), 4.919V
OPP	915.48W (140.8%)
OTP	✓ (180°C @ secondary side)
SCP	12V: ✓ 5V: ✓ 3.3V: ✓ 5VSB: ✓ -12V: ✓
PWR_OK	Operates properly
NLO	✓
SIP	Surge: MOV Inrush: NTC thermistor & bypass relay

The PSU shuts down with 77.82A on its +12V rail. We suspect that this is not because of over-current protection on this rail, but due to under-voltage protection.

 

In our opinion, this PSU's over-power protection is set too high; it should kick in at around 120-125% of the maximum-rated capacity to keep the +12V rail within spec.

 

Over-temperature protection has a pretty high triggering point, too. This is something we've encountered in plenty of semi-passive PSUs.

So you just have to be careful about not overloading the PSU is all

It can't be exceptional (at least not in the way you mean) and be a safety concern.

For one, please no power supply calculators until someone kicks their heads in and they make something even remotely accurate...

 

Two, yes, OTP and OPP are issues the G3 faces. It's fine for 99% of people who don't put their PC inside of a sandbag and load it up with dual Titans, but it's something worth noting.

That's my understanding as well.

Y I think the issues are worth noting, but even the Tom's reviewer who identified those potential concerns concludes that it is an excellent unit.
