Actually, they do have meaning. You have to evaluate their input correctly, but they do offer value. Professional reviews also have limitations. The most obvious being the inability to determine long term reliability or the presence of non-obvious factory defects. Did you criticize people for being sheep? YOU ARE THE SHEEP! You know nothing about the M12II. You are just bashing it because that is the group think narrative on this forum.

You might not want to ask a question you don't really want to know the answer to. Let's just say that this is not the first place I have encountered him. Mask is HIGHLY knowledgeable and being quite tactful in his critiques. You guys tend to be dismissive of people with much more knowledge and experience than yourselves. You might want to rethink that approach.

Actually, Mask has already contributed in a meaningful fashion. For example. A couple weeks back a kid was about to waste his money replacing his perfectly functioning Seasonic Focus because it was in Tier D. Before he did so, he stumbled across one of Masks earlier criticisms of the list and realized that something was rotten in the state of Denmark. He started asking deeper questions and we convinced him that the list was bunk, saving him $100. Also, this forum is short on knowledgeable, experienced members, and long on group think. Someone who is both knowledgeable and capable of drawing his own opinions should we welcomed.

But that is the point I was trying to make. They weren't fixes for the S12II because it was never a problem to begin with. There is a serious disconnect between real world performance and theoretical performance in many instances in this forum. The S12III just happens to be a newer design and by extension, included the newer elements. And it isn't better. You have to do more than win one performance category to be better. OTP was optional when the S12II came out. It is required now. You are thinking of undervoltage, which isn't mentioned in the spec.

The S12III isn't the S12II's replacement. Core will get that job if we ever see it here. The S12III targets a lower market segment that was not previously targeted by a branded Seasonic product. People just assume its the replacement because of the name. Kind of like the Athlon II which replaced the low end offerings, not the original Athlon. It certainly doesn't hurt to have them, but you vastly overstate the importance of having a complete set. The only reason everyone has all of them now is they are now required by the ATX spec. That wasn't the case when the S12II was designed and it was never added because it was never needed.

The system 9 loses every category except voltage regulation. The VS loses every category period. That type of flim flam analysis just highlights how far off the mark the narrative on this board has been. The VS isn't even meant to compete against it. It targets a lower market segment. Again, the S12III wins one category against the S12II. And as I pointed out, the Manufacturer of both units agrees with me. Stop with this pathological obsession with protection circuits. It didn't need OTP for last decade and a half. It isn't going to start now just because you want to be OCD about it.

Yes and no. Seasonic rates it at 40c, but it gets a 50c upgrade at 80% load or under. However, that is a conservative rating for that unit. If you don't believe me, Antec and PC Power & Cooling used to uprate them to 50c with no temperature modifications. And they cared about quality in those days. That has nothing to do with reliability. It has been moving down the food chain over the years as better units have come out, but it started out as a $120 psu. It had a lot of wiggle room. The only true budget PSU's that can compete with it are the CX and the Bitfenix. All other units cut too many corners or belong to a higher class. Not only do I disagree with you, so does seasonic, who has the S12II above the S12III, but below the Focus. But what does the manufacturer know?

And therein lies the problem. They don't really know anything about the S12II. They were told it was bad and they just keep repeating that same nonsense. Its group think, not analysis. That's why they have to pass it off to someone else when you ask why. You should already know why if your going to advise for or against something. This has been a problem for a while on this board. The CX is a great unit, but It's in the same class. It has different strengths and weaknesses, but its around the performance level. If you send it back, get an Corsair RMx or Seasonic focus. Those are actually better PSU's, but they are also more expensive.

Don't forget PSU model

I have already seen it. To which part are you referring?

You mean a power supply that was designed to run the most power hungry cpu's and GPU's we have seen this century, and has done so with distinction for the better part of a decade and a half, suddenly can't do it because............why is that again? It "fails to feed the 5700XT standards"? What's standards would those be exactly?

No worries. Such details are easy to miss.

There are trade offs for every unit in the budget category. If you want the whole package, you have to pay more. The strengths of the S12II are great build quality, heat tolerance, reliability history and ripple suppression. It basically has a reputation for being semi-indestructible and it earned that reputation powering some pretty crazy setups over the years. That's why it's still tops on my budget list. You can throw just about anything at it and it will hold up really well. But I do get why some like the newer units.

Nothing worth worrying about.

He already has the S12II 620. I still like it better than the CX, but the CX is good. Really good.

Yes. With room to spare.

It will be fine. The S12II series is very reliable.

I don;t really start worrying about PSU's of that quality until around the 10 year mark. Though, I typically purchase new PSU's for new builds. If I were in your situation, I would just roll with the HX 850. Moments like this are part of why you purchased that kind of quality to begin with. Don't be afraid to use it.

Just make sure it is as advertised

That will make the trouble shooting process more time-consuming, but it should still work. You said you had three fans on that panel, correct?

Still doesn't sound like a PSU issue yet. You should rule out software first before moving on to hardware. You don't want to replace something and find out it was drivers all along.

I agree this sounds like fan noise. Try removing the fans one at a time and see if there is a particular culprit.

The Vega 56 puts a lot of pressure on the PSU, but I wouldn't assume it is a psu issue just yet. My first though reading your post was driver issues. Crashing while uploading a Youtube video didn't sound like a PSU issue to me.

Can you give us your full system specs?

This is private seller that is offering the RMx?
