9950x3d, 5080. Can I get away with a Platinum 850w, or do I go for 1000w?

Pretty much title. What is the downside of 850w? Is saving the $30 worth it?
HarrisonGreen@reddit
Why 9950X3D though? The 9800X3D is faster in games and cheaper.
MarkDirtt@reddit (OP)
I responded to another, I will paste here:
I decided on the 9800x3d at MicroCenter, went home to look at the receipt and noticed I was charged for a 9950x3d. The employee put the wrong cpu in my cart 🤷 o well
To add, it was 200$ extra with the mobo bundle. I was torn between both since I run other processes like Minecraft servers and high res discord streaming anyways. So i dont mind it. Whatever I got, its beating my i7-8700..
HarrisonGreen@reddit
In that case, 850W should be fine, according to this: https://dlcdnets.asus.com/pub/ASUS/Accessory/Power_Supply/Manual/RECOMMENDED_PSU_TABLE.pdf
But you probably won't have much headroom for a second GPU for PhysX or Lossless Scaling.
wwny_@reddit
Does anyone even use PhysX anymore?
funkyfritos@reddit
I love my pcpower and cooling 1000watt silencer. Don't even hear it!
JuZNyC@reddit
850 will work but the reason I buy over spec PSUs is for the silent mode fan curves.
Errorr404@reddit
Calculate how many watts you are going to be using and choose a PSU where at max load you are within 50-60% of total load on the PSU so you get the most power efficiency.
ime1em@reddit
it's the bare minimum recommended according to nvidia. https://www.nvidia.com/en-us/geforce/graphics-cards/50-series/rtx-5080/ .
but since u can afford a 9950x3d and 5080, doesn't really make sense to not get 1000w+ PSU in general.
NYdude777@reddit
The price to performance nerds are gonna be clutching their pearls.
ime1em@reddit
With ram prices these day and possibly shortage on storage, I wouldn't be surprised OP wants to use that $30 on those said items

Yz-Guy@reddit
Wait. So you paid for a 9950 and got a 9800? Isn't that like a 200 dollar difference. Id be going back so quick to address that.
KillerSpectre21@reddit
Sounds like he wanted a 9800X3D and the employee accidentally handed him a 9950X3D instead.
He didn't check the packaging and only realised he had a 9950X3D when he was looking at the receipt.
Toast_Meat@reddit
Are you going back to get that sorted out? That is definitely not an "oh well" scenario.
Naerven@reddit
For a rtx5080 I would spend the extra $30.
IrrelevantTale@reddit
Yeah 5080 runs about 700 to 750 and the 9950x3d runs about 200 to 233. Def need 1000w at least.
macuser007@reddit
even my 5090 is default locked to 600W
ssuper2k@reddit
5080 goes at 360-400w, Not more
macuser007@reddit
even my 5090 is default locked to 600W
Toast_Meat@reddit
Where on earth did you read that.
MintTheGod@reddit
The 5080 isn’t running anywhere near 700-750w, it gets barely half that
pvdas@reddit
I have a 5080 and a 9950x3d, and frequently use programs which max out the GPU (350W) and all cores of the CPU at once. Max power draw with this is never more than about 650W (measured with a smart plug, and that also includes a monitor plugged into the same power strip). I have a 850w gold PSU.
If you think you will upgrade to a -90 card on the future I would get a 1000W PSU. Otherwise unnecessary.
MarkDirtt@reddit (OP)
Now I have a different question, do you hear the PSU get louder under load?
kexkaka@reddit
I once had a 750w corsair psu with a 3080. When playing demanding games the psu fan got pretty loud, then I changed to a 1000w and never heard the fan after that. Since a 5080 consumes a little bit more than a 3080 850w should be fine but I would go for 1000w for a more silent experience I have a lot of rgb and usb devices though
Codys_friend@reddit
I have a Corsair Shift 1200 and I've never heard the psu. When my rig is under heavy loads, I hear the fans.
pvdas@reddit
If it does it's not louder than the case fans, but yeah probably.
dertechie@reddit
If it’s at the plug that’s also including the efficiency of the power supply. So that’s probably only about 550-575W actually being drawn by the components.
Codys_friend@reddit
1000, no brainer.
VacuousMike@reddit
I agree with you I went with a 1000w psu for my 7800x3D 5070 TI build that way if I want to upgrade in the future I can no problem
UneditedB@reddit
I’m running my 9800x3d and 5080 on a 750 no issues and that’s with me overclocking to 111% on my GPU at times.
5080 is 360-400 max with OC (if it’s actually running at max power) and the 9800x3d is 120 max (if it too is running at full load which is rare to have the CPU maxed out while gaming)
mentive@reddit
I'm over here with a 9950x3d / 5090, running off an SF1000 🤣
UneditedB@reddit
I’m currently using a 9800x3d and 5080 with a 750w PSU and i actually overclock my GPU to 111% power at times.
Lewdeology@reddit
I don’t understand this mindset, you’re already spending 5080 money with a 9800X3D, literally why are you trying to skimp to save a $30?
MarkDirtt@reddit (OP)
Cause I spent 5080 and 9950x3d money. Ill take 30$
Awesomeguy215@reddit
Which one you got
MarkDirtt@reddit (OP)
1000, not necessary but 30$ for 150w? Oh well
Otic0n@reddit
I run a 9950x3d and a 5090 on a Loki 850 watt. You should be fine with either.
580OutlawFarm@reddit
Me? I'd go for the 1000w...my okd 12600k/3080 12gb build has a 1000w....my new 9800x3d/5090 build has a 1300w...I can hit 1k watts pretty easily with my phanteks nv7 case, added case rgb, all phantwks d30 rgb fans x9, arctic lf3 pro argb 360mm...and of course the damn 5090 pulling 604w max itself
dertechie@reddit
Have you measured this 1000W? To get there you’d be talking like ~250W of RGB unless you’re overlocking all that. That’s some next level unicorn puke.
cszolee79@reddit
I'm using a 9950X with 4080 Super and a Corsair RM850.
tronatula3@reddit
850w is more than enough. Recommended wattage on the website is just for precaution only. Use real wattage calculator on the internet to know the real needed wattage.
Sp3ctralForce@reddit
850W should be fine, but your already spending quite a bit, I'm sure the 30 isn't going to mean much, and will allow more flexibility later.
Also, check Cultists Network for a high quality gold psu, it'll most certainly be cheaper and better.
ariukidding@reddit
I’d even go 1200w, they perform at peak at 50% of their capacity. Also gives you room if you are to upgrade. Look into S tier PSUs and check if they are on sale. Perhaps why im patient at deals, 1000W/1200W on sale is closer to 850W regular price. PSU is probably one component you shouldn’t cheap out.
pacoLL3@reddit
Getting a ridiculous wattage is not the opposite of cheaping out.
People mean "quality" when they say that, not getting a 1200W PSU when your entire system will draw 500-600W under load...
And they perform at 99% when they are 80-85% of their capacitity. You absolutely do not need to double the wattage of your systems power draw.
ariukidding@reddit
Also, the graph literally points most PSUs at their peak around 50%, but the benefits are still quite marginal up to 80% factoring in price premium which goes back to my point. It only makes sense if you can find a good deal.
ariukidding@reddit
Thats true, you don’t need it. But for the price difference and the headroom it gives you for future upgrades, it’s a no brainer. Im only suggesting this in the context of finding a good deal, since we are approaching black friday/holiday season. A month ago i bought a 1200w platinum, only $20 more than the 850w platinum because it is on sale. Again, no brainer.
NYdude777@reddit
Never cheap out on a PSU.
dertechie@reddit
Platinum 850W is not in any way cheaping out.
NYdude777@reddit
On a 9950x3D/5080 build it sure is.
dertechie@reddit
It provides around 200W of headroom over the steady state power usage of the system with both CPU (170W) and GPU (360W) full load. Assuming ATX 3.x it is certified for comically high transients. It’s not going above 80% PSU load for any time frame not measured in milliseconds.
Why, exactly, do you say that this is insufficient?
digital_n01se_@reddit
would you save 30$ while you can spend $1000+ on a 5080?
MarkDirtt@reddit (OP)
Considering new RAM prices and the fact i spent what i did on the top cpu and 2nd top gpu, id like to save $30 😭
pacoLL3@reddit
Then just get the 850W PSU.
You still have 200-250W headroom and it's literally Nvidias official recommendation for a 5080.
They recommend it for the 4090 too btw, which draws even more power.
You would have zero issues with a 750W PSU even.
You will be absolutely fine with 850W.
dertechie@reddit
I can use that logic to justify a 1500W Titanium PSU. A good, solid A tier Platinum 850W ATX 3.x PSU is more than sufficient. Past that is gilding the lily. It’s like putting a 5 inch fart cannon on your Civic - it’s not making it any faster.
You can justify it if you see a 5090/6090 in your future, but if you aren’t planning on dropping 2000+ USD on a monster GPU there’s little point.
digital_n01se_@reddit
I get it.
Thanks
NYdude777@reddit
Guys got the best cpu on the market and the top 3 GPU and is worried about a $30 upgrade for the literal heart of the PC. I don't do "good enough" on a high end build like that.
pacoLL3@reddit
Just because you have money, does not mean you should be stupid or excessive with it.
A 850W PSU is more than enough for his system and will cause zero issues whatsoever.
dertechie@reddit
So vibes. Got it.
pacoLL3@reddit
It's literally what Nvidia themself recommend for the GPU....
BandicootKitchen1962@reddit
Crazy talk.
kev1059@reddit
You should get a 1000w PSU as a more robust one can handle any spikes, and also it will last longer under higher load.
pacoLL3@reddit
He will have absolutely zero issues with spikes with the 850W PSU too.
catccino@reddit
For 30 dollars and the extra headroom I think a 1000w is always worth it.
I just look at it like if you had to ask this question then you’ll always wonder if 850w was enough.
30 dollars for the peace of mind seems worth it to me.
pacoLL3@reddit
850W is the peace of mind headroom version though.
His PC will reach sriund 600W max, maybe a bit more in extreme scenarios and will never come close to 700W.
thestillwind@reddit
Why not
ThenExtension9196@reddit
5080 you’ll be fine. You won’t have heard room for a 5090 or next years gpus tho.
Jeep-Eep@reddit
Get the kilowatt and save yourself potential headaches down the line.
dustinthewindreddit@reddit
I have a 4090 with 5600x. Got away with a 750w. Then I found out it was slowly melting. Go with the good one
0wlGod@reddit
go with a 1000 atx 3.1
tacophagist@reddit
I used to try to get away with a lesser power supply. By used to I mean once when it died and I had to get the more expensive "overkill" one anyway. Just get the better one and save yourself the hassle.
Borigh@reddit
You actually want this, if you want to save the $30. It's really quite efficient, but more importantly, it's by far the least expensive of the A-tier >1000w PSUs.
dertechie@reddit
2 hours before a Montech Century II comment? Man, y’all slow on the draw today.
Borigh@reddit
The price on their 1200w one has already shot up to reflect the quality, gotta get while the getting's good.
kemicalkontact@reddit
And 850 will be fine. If you're overclocking then the 1000 will be more efficient. Stock TDP is like 530W combined? That's around the 50% capacity load.
a_hopeless_rmntic@reddit
the power supply is the one piece that distributes hundreds of watts through all of your other parts
how many fans will you have? and do you want to overclock?
really the short answer is over-spend on your psu
go 1000w
PM_ME_UR_POO_STORIES@reddit
The only downside is that I guess it is theoretically possible you might want to upgrade components beyond 850w in the future. But aside from that there is no downside.
dertechie@reddit
If you see yourself picking up a X090 at some point, go 1000W+. Otherwise, 850W should be plenty.
HighYacare420@reddit
1000+
