Will my power supply be safe for this build?

this is the power supply I picked up a few weeks ago before I read about 12v vs 5v and the amps required for each. i would go and use the guide and pick another psu, but unfortunately i've already made the purchase. i'll do a return and pickup something else if necessary, but if this will work i won't bother. my planned build is going to be:

threadripper cpu
8 ram slots
gtx 1080 for passing through to a windows vm
7 wd red 8tb(5400rpm)
7 seagate exos or ironwolf (7200rpm)
~2 nvme ssds
2 lsi 2008hbas
2-4 sata ssd's
potentially a couple more pci related things like a usb controller to pass through to the vm, maybe some pcie storage
a mountain of fans


this is the power supply's specs

What case are you using?

So as of yesterday I was thinking about getting a deep silence 6 which is a full atx case. That said after reading a bit more I'm actually considering it may be a better long term decision to just send this power supply back and get a supermicro 846 off of ebay. I would still like to know whether this power supply would work if I decided to go for the deep silence build though. Will the 846 be able to house a full graphics card and a standard cpu cooler?

The power supply sizing article discusses how to calculate sizing.

The calculations are the same whether you are planning to buy a supply, or are trying to evaluate whether an existing supply is sufficient.

An 846 is designed to have redundant supplies and is expected to be able to fully power most server configs. With a graphics card you may wish to opt for the 1200W PSU modules instead of the somewhat more common 920's. If you go for a PSU sizing that is too small, you may not be able to safely start the system if one of the PSU modules has failed.

You should never ever use "standard CPU coolers" in a Supermicro chassis. Buy the Supermicro ones. The system cooling is designed to give you redundant cooling that has been worked out by an engineering team that designs these things professionally. Make sure that the cooling shroud is properly installed and don't do anything stupid like trying to switch out the fans to "make it quieter." A chassis like the 846 is reliant on static pressure differential in order to keep your drives cool, and the fans are of a much higher quality than any of the fans marketed to hobbyists or gamers. They are noisy because when you're generating high pressure that's just what happens.

If noise is a critical issue, then the full ATX case is usually a more flexible option.

I've actually read that already and I'm a bit confused(and stupid unfortunately). I don't know whether my drives will be using the 5v or 12v rail. I'm assuming it's the 12v rail. Exos says it using 2.6 amps during spin up and the wd reds say they use 1.8 amps during spinup. I'm assuming that is all on the 12v rail? how do I choose which rail it uses? Does the power supply do that automatically? Either way that means it should be using ~30 amps which leaves me more than half the amps left over for other things. Less than half. Add in an additional 20 amps for the gpu and that leaves me with 30 amps left over for stuff like my hbas and cpu. If my math is good and I'm understanding it properly it should be more than enough even if I replaced my reds with 7200 rpm drives and was resilvering both vdevs at the same time while maxing out the gpu and cpu.

Does this sound robust? this is for the atx build with the psu I listed in the op
