Ok this is final bulid update.

Somehow, I don't believe you

Somehow, I don't believe you

It's true and very much set in stone.

My old 750 Watt PSU gave me all kinds of problems w/my o'clocked 9700k and my o'clocked 1080ti. When I replace the 1080ti w/the 4090 it became a nightmare of system resets. It's an old Rosewill Capstone 750 Watt 80 Plus Gold PSU though and probably ten years old by now. I ended up dedicating a Seasonic 850 Watt PSU to the 4090 and cooling fans at which point all my system reset issues went away. Considering the way power requirements and TDP just seem to be going up w/every generation I wish I had bought a 1kW PSU.

Are you running two psus? The one thats failing (but shouldn't - time for the garbage) is now only supporting a light load, at worst, like 250w or something amd the 850w is just for the gpu? Just use the 850w!

Are you doing what you told me not to do?

I am running two PSUs, the interesting thing is the 4090's +12V 12VHPWR power rails aren't connected to the PCIe slot +12V power rails -- they're an entirely different circuit according to my DMM. I actually want to replace the ten year old Rosewill 750W Capstone with a SFX 850 Watt PSU so I can get more airflow to the 4090.

This is why I often use SFX PSUs in even larger ATX cases (more like dual-chamber ATX). A high-quality SFX doesn't run hot, is quiet, small, and has shorter cables, so you don't need additional space. However, before you decide, read about the fan speed at 30%+ load, as this is tricky. Most manufacturers cheat on the noise specs. Usually, it's out-of-the-case fan specs without a specified point of measurement. 20dB and less is impossible for a 1500RPM+ fan measured from 3 feet.

@Woomack
That's a great point about the fan noise. A 92mm fan is going to have to spin faster than a 100mm or 120mm fan to cool the PSU.
I did run the coolermaster V850-SFX outside the case for a while as the secondary PSU for the 4090. It didn't seem to be particularly loud.
Cybernetics (a company based in Cyprus) tested the coolermaster V850-SFX and found an average of 37.32 dB(A) for the Avg. Noise Output.
All the cables included w/this PSU are 18AWG, I'd much rather have 16AWG.

I didn't know you already have an SFX PSU. I said that about Coolermaster, as their products are really random. Some are good (but usually good for the price), and some are below average. I don't remember who makes their PSUs, but I haven't seen bad SFX 80+ Gold or higher PSUs regarding stability ... even from really weird brands. Bad are generally fans or fan curves, as some models spin them up to 100% speed at 50%+ load. It's usually ~2800 RPM. The problem is that most PSUs have warranty stickers, so if you remove them, then you lose a warranty.

~37dB is what I can believe. The typical room noise is around ~35 dB, so typically, the whole PSU measurements are around ~40 dB or more. I say that because fans are much louder in a tight PSU case with grill and everything around, than tested on a free space.
I remember when we were testing PCs for CE certificates in my old work (15-16 years ago). We took computers to the lab at a local university, and the fully passive PC had 22-23 dB measured from a 1m. It was because of all the coil whine and other typical noises (and it wasn't even any high-end PC). Not much time later, the market was flooded by fans specified for under 20 dB, and people believe in that until now. I can believe that Noctua has low-speed fans like that, but not a cheap Chinese brand.

Ok gents... this thread is about Flamethrower's build. A one or two post aside is one thing/ok.... but this is another.

Take it to PMs or maybe create a thread, as it is a good discussion (it just has nothing to do with the OP).

Did you get the g.skill 7200 RGB cl34 memory? I just snagged some 2 weeks ago If so I read a review where they OCed it to 7200 @ 34-41-41-41-81 w/1.45v which I’m running now.

I have it but my system is not done yet.

That PSU is not part of my rig??????

@Flamethrower1972

Did U ever consider one of the AMD X3D CPU's for your build?

I already have an ASUS Z790 H MB. And I don't use AMD product's.

 

[magellan]

Why the AMD hate? In some games the X3D CPU's beat anything Intel has hands down -- even when the Intel CPU's are overclocked.

 

[Flamethrower1972]

Just set in my ways.

Some is not the majority.

 

[magellan]

Some is not the majority.

The AMD X3D CPU's beat Intel CPU's (even overclocked) in MOST games. It's not even close to a 50-50 split and in some games AMD X3D CPU's dominate Intel, but never vice-versa.
