If it’s for gaming only then 9800x3D is generally better or the same at worst.
Anyway, modern ATX3.0 or newer PSUs should be plenty enough as they can handle transient spikes of 200% of their rated power. So 1700W in this case.
I would still recommend a PSU that has 5 individual 8pin PCIe/CPU connectors so you can avoid daisy chains. most amd cards still use 8pin connectors.
My 7900xtx + 7800x3D peaks at about 550W I think.
I’m personally an old school and like to keep my PSU at or below 50% limit but that’s not needed today. And if your PSU won’t be enough you can always upgrade later. The worst thing it can happen is that your PC will reset under load.
Thanks for the reply!
16 cores for multi-tasking, work and futureproof. Right now my 8core 5800X is taking a hammering when I have my second monitor on and YT playing in the background.
The PSU is the HX850. I don't know if it's ATX3.0 but it's got all kinds of connectors - which I need to look around for.
I'm assuming if your computer is maxing out at 550W I should, hopefully be okay with an additional 50W. I'd probably be hitting around 650W if I upgraded to everything, assuming the AIO takes about 20-30W
I'd argue yes, but you *may* want to consider 1000w. That leaves you headroom, as presumably you want to keep this machine for the future, so, if you planned on getting a CPU upgrade, or a new GPU, that 1000w would allow it, whereas the 850w could be cutting it fine.
Cooler should be fine measurement wise, THAT SAID it's an NZXT so REALLY look at the software behind it and ideally look at reviews. When i was looking for mine, NZXT were not very well liked on this point. Software plays havok with other proprietary systems (Such as Corsair's lighting software or Armoury Crate from Asus, so be careful if your using either of those.)
--- If you haven't had a look, look at ThermalRight's liquid Coolers. Cheaper than other manufacturers, but the stats back them up. They're very good coolers. Not sure if there's a 420mm one though. (My case takes 360mm, so, there was no need for me to look at these when i was buying one.)
I would advise caution on the 990 pro. They're not.. great quality. If anything, i'd keep your 980, and buy a smaller 2TB drive as a secondary (Even if it's a 990 pro, as long as it's a good price. They're often on discount (for a bad reason). You REALLY don't want to be using the 990 pro as an OS drive.
If you end up with having to RMA the 990, you're out of a computer, and they don't have a great track record at current.
The 980 pro will not handicap you. The differences between GEN3 AND GEN5 drives really don't affect games all that much.
I wouldn't replace the 980.
Thanks!
I'm at the point where I need to reformat my SSD anyway because I partitioned it so Windows 10 would be on it's own partition and everything else would be on the second larger partition. But, with windows updates, the partitioned drive is practically out of space at this point which is causing me quite a few issues(Downloading certain software which will only install on the OS partition). I'd mainly be looking to upgrade for the larger space, the 4TB. I had read some issues with their 990 Pro SSD's from a year or so back but most recent reviews rate them highly - is this just mainstream media ignoring the issues or have the issues been addressed?
I'd likely be looking to buy a MLC version as opposed to the TLC(Apparently the MLC version is better quality and has longer r/w than standard TLC).
For the cooler will the 420mm fans require a larger bracket in my case or is it all universal? I'm just assuming a full tower has bracket sizes for coolers that are standard and no matter the fan sizes they will fit into a full size tower?
I'll look into the software aspect as at the moment I run SteelSeries GG for peripherals, AMD software suite only.
My case is black and the side panel is pretty dark - you can see inside but it's not clear glass, it's darkened so I likely wouldn't see the AIO screen unless it was really bright - not that I look at my desktop much(It hangs under my desk).
for highly threaded loads the 9900x3d is better just due to more corez
for gaming the 9800x3d is better since they can boost to higher clocks
games like better core performance
420aio should be fine with the am5 cpus
amd underrates the wattage on their cpus
with expo off and everything at stock, sure the 9900x3d can draw 65w
but their max draw can be over double that
figure 130w for cpu to be close enough
and 7900xtx can be upto 460w
add 100w for board, ram, fans etc..
lots of usb devices can draw more power too
if you need more usb ports, get a pci-e usb 3.0 card with extra 2.0/3.0 headers
and slot covers with the ports and cable for the headers
+100w overhead maybe more
and best to keep the psu under 80% load for best efficiency
puts it around 1000w to be safe
850w would probably be ok as long as the gpu power is limited to <400w
I do have two charging cables connected too which is at least another 20W in extreme cases(Wireless charging pad for watch/phone).
I'd definitely be cutting it fine with the PSU...
Something else is wrong there.
If you aren't running professional programs (in which case you should also look into Intel to check which chip your use case prefers), a 9800x3d is a better cpu than the 9950x3d.
Your existing psu will be fine, upgrade it when it is needed.
Psu's, atleast good ones, can provide 100% of the stated power.
The efficency rating is how much of the power it pulls from the wall it converts into usable power.
So a higher rated psu is very marginally cheaper to run vs a less efficient one, it has nothing yo do with how much of its, stated power it can handle.
A big reason to go with an excessively larger psu is to keep the fans off as much as efficency sake.
That's base clocks TDP and I imagine you will keep boost on, that CPU can peak at 260W, gaming though you will probably be in the 150W range, but account for the peak use.
If you aren't changing your GPU there really isn't a need for you to replace your 850W PSU with what you've described for an upgrade.
The efficiency will however change depending on the load %.

https://www.techpowerup.com/review/corsair-hx850-v2/5.html
You can see from those 3rd party tests that your PSU will have it's peak efficiency at around 350W load, however, it's above 85% efficiency from around 150W all the way to its maximum 850W.
EDIT: I'd also concur with others that you would likely be better off with a 9800X3D unless what you describe as "multi-tasking, work and futureproof" is actually a workload that would benefit from the 9950X3D. What specific things are you referring to in regards to "multi-tasking" and "work"? Because as Monk noted, unless you're watching youtube in chrome with 100 tabs open while you're trying to game you probably have something else which is negatively impacting your performance that isn't stemming from "watching youtube on your second monitor while gaming.
I would save on a X870E too, example my X870 Tomahawk has 12 USB ports rear or 15 including front case or potentially 21 if I use all the internal headers, unless you need more than that even? You can always use a hub in the type-c port too.
With a 9800X3D you can knock down to a 360 AIO for a saving.
And personally I would grab a 1TB gen5 M.2 for OS and programs with a 4TB M.2 in a second slot for games/storage, better for if you need to install windows again for whatever reason, I don't like to partition drives personally.
I was thinking of doing that with my existing 1TB SSD. It's still good, should still be quite fast that I wouldn't notice any difference between my old 980 1TB and whatever new one I get as a 4TB upgrade.
So, I should be within the breadline with an 850W PSU but - am I wrong in my interpretation - it would cost more to run the 850W PSU than a 1000W PSU and the 1000W PSU would be better for any power spikes?
You might get a few more ports and the 3rd & 4th M.2 slots are gen5 vs gen4 which makes no real difference as they all share the same x4 PCI-e to the CPU along side all the USB ports.
Ahh ok, for games the cheapest (good brand) 4TB M.2 will do, gen3/4/5 don't make much difference for games, not yet at least.
A good 850W is fine I imagine, I have a 9800X3D + 5090 and it runs on a UPS so I can see the power draw and I don't use that kind of power, peaks at about 750W on a real heavy game, Cyberpunk with path tracing kind of thing, that's not including spikes though as the UPS can't see them, I run a 1200W PSU.
If you have a ATX 3.0 PSU it's already made to handle spikes, 200% for min of 100 microseconds.
As for having a bunch of tabs open to multi task, I tend to have 100 chrome tabs open at any given time on my htpc using an i5 13400 with 32GB ddr4 3600 and gave never had an issue with it while gaming, it's a bit ram intensive but shouldn't cause any slow down abd definetly not a reason to go with a 9950x3d
- X870e has dual chipset vs single chipset on x870 non e what means more possible pcie lanes and potentially more ports. Most likely a waste of money for gamers. AMD in particular doesn’t care much about motherboards as it doesn’t require crazy memory tuning and voltage regulation to perform well. Any board will have close to identical gaming performance.
- 9800x3d is a better pure gaming CPU than 9950x3D. Not just “almost as good” but actually better due to having just one type of cores on a single CCD. Less latency problems. Less scheduling problems.
- nvme speed make virtually no difference for gaming. No need to spent on gen5 for extra money and potentially more heat. Gen4 is a sweet spot right now for price/size/performance.
If you haven’t bought the 7900xtx I recommend 9070xt or 5070Ti instead due to a far superior upscaling capability. I say that as a 7900xtx owner.
The "E" "version" of AMD's chipsets is just 2x of the chipsets for more IO.
The X870E is just two X870 chipsets. With what you're talking about doing for your upgrade you really don't need an X870E board and you'd be largely wasting money you could put to better use somewhere else in your build.
That all depends on the efficiency curve of whichever PSUs you are comparing. Generally speaking though, yes your interpretation is wrong. However, even if you're comparing a 1000W PSU which has a slightly higher efficiency at your nominal wattage compared to your current 850W... you'd be saving yourself on the order of a couple pennies a month.
In regards to handling transient spikes in load, yes the 1000W would have a slightly higher peak; but that is largely irrelevant with your use case as you are well within your PSUs rating.
To put it another way; for the amount of excess money you'd be spending on those things..
You could probably sell your 7900XTX and upgrade to an RTX 5080 Super with the difference.
EDIT: p.s. I'd also look around at other Gen4 M.2 SSDs vs a Samsung 990; Samsung isn't the dominant force they once were back when you probably got your 980 Pro. There are better options for less money. For Gen4 the WD SN850X, crucial's higher end models, Micron's 3400 series, or some of the Team Groups SSDs usually all are better performance:$ than Samsung's 990.
