Would you need a 750 watt unit for the new NVIDIA 3080/3090?

[Jackthedragonkiller [Chirch]]

I was looking at NVIDIA's website and saw they recommend a 750 watt unit for the 3080/90 BUT, that was with a new i9-10th gen processor, I have a Ryzen 7 3700X. I run that with a GTX 1660 Super with a 550 watt unit.

Now, I do need to upgrade anyways just because it's a 4 year old unit and recently my PC has been shutting off randomly at night. I have 100 USD for my birthday and with that I could get a 750 80 Plus Bronze from Corsair but a bronze for a 700 and 1500 USD GPU? Nah. Of course though with my 300 dollars for Christmas, that can't even get a 3070, but I want to future proof my PSU anyways so...

Edit: It occured to me that I could sell my current 1660 Super and probably get a couple hundred back since it's only about 7 months old. My plan for 3000 might come true.

I keep telling people, spend 10 bucks on a power meter from amazon, plug your pc into and see just how little your pc actually uses.

or a psu with lcd display which shows total w :)

Yeah, but, that only works on cases where you can see it and most good cases have the psu hidden away these days, plus, you pay a premium for it.

But, if your case would show it, they do look cool.

For 3090, might even need a decent 850 watts minimum PSU, as a 3090 can have a full load TDP of approx 350-400 watts depending on the exact model you buy. This will be especially true for people using a higher TDP cpu like 9th or 10th gen i7 or i9, Ryzen-9 or ThreadRipper; especially if you plan to OC the CPU/GPU

For a 3700X which is only 65W TDP, you should be fine with using a 750 watt PSU with RTX 3090 as long as it is a very good PSU

550W is basically the bare minimum for a budget PC.

But I also wouldn't waste my time/money getting a 3090, as a 3080 for half the price will still stomp every previous gpu into the ground.

the 3080 10GB is a bad buy.if your not going for the 3090 pricey as it may be.wait
for the TI series to release otherwise you'll be buying again in a year.2 years at best
there will be alot of buyers remorse with the 3080 10GB when the TI release.
the exception would be if you have a lesser card now 3 to 4 years or more old (like a 980ti) then the 3080 10GB makes more sense.

a 750watt gold PSU will do the job for a 3080 or 3090

If wait a 3080 ti must wait a 4000 series too XD never finish the wait :)

[Bad 💀 Motha]

Well in that case just wait til we move beyond X86 computing altogether *sarcastic grin* ;)

Or they have 15 old hard drives hooked up or something. I still have a 12 year old 420W Thermaltake PSU that I paid $40 for in my son's system (with hand-me-down parts), and have never had an issue with a PSU in almost 30 years of building PC's.

If those specs don't change in that PC, sure. But modern Motherboards require today's PSUs. It's that simple. Building today means having; 24pin atx, at least 1x 8pin eps, at least 2x 8pin pcie, the rest is all optional like sata or molex since we have M2 SSDs now.

A PSU before approx 2012 or so wouldnt even work on a modern PC because it lacks the specs and connectors needed.

I'm still using the 500w PSU that came with my Antec Sonata III case that I got back in 2008. Put in a 350b (I think, going from memory) motherboard and a Ryzen 3600 back in February and don't recall any connector problems or such.

Although it _might_ be adequate to support an RTX 3070, it would be pushing my comfort limit, so I'm looking at upgrading my PSU before then to be ready for a GPU upgrade and possibly a Ryzen 4000 if my bios supports it.

Ideally id wait for the 3060 or AMD big navi and probably be happy with that, but I still have a GTX 670 now, and I want to be able to play cyberpunk 2070 (and other recent/future games) without running potato mode (which has been the case for pretty much any game in the last couple years). So for me, a 3070 is looking very tempting upgrade, and even if I wait for the 3060, a new PSU will give me peace of mind when I consider how old my existing one is.

I think a 650 or 700 would probably be a good step up, but i havnt kept up on trends and brands etc. Does corsair still have a good quality rep, and what other brands are considered high quality/reliable these days?

Should I also be concerned about needing more cooling with a 30x0 card (might need a new case too)?

Fun fact is a 3070 with 220w is only 20w above your 670 gtx. In combination with a ryzen 3600 which uses close to "nothing" you dont even have to upgrade your old psu. This doesnt mean you should wait till it fails. Yes corsair ax/hx/rm/rmx are still more then fine but there many more from seasonic, be quiet, antec, super flower.

[das3erawsdas]

its fine 750w

Thanks for the info and recommendations, I did not realize it was a comparatively minor increase in power use. I should probably do a power calculator on parts picker or such, but yeah, it's probably time for a new one either way just due to age.

[Bad 💀 Motha]

People seem to forget so quickly...

Go look at what the TDP was even for stock nvidia reference cards such as...

Gtx 570 and 580
Gtx 670 and 680
Gtx 780 and 780 Ti

I grabbed 2x 680 at launch and did SLI

psu calc sites are never right
they over estimate to force you to think you need a bigger psu than you really need
and also to cover for low quailty psus

It showed me usage of 478W if I put a 3070 in my system, which I thought was reasonable with a 3600. I understand these are likely the highest load you will ever experience, but it tells me that a 550W PSU is more than enough for a 3070. I don't look at the 750W PSU that it 'suggests' that I buy...

People will only have buyer's remorse because they are under the erroneous belief that they need 16GB of VRAM to 'future-proof' themselves. Ridiculous. Most of these same people upgrade their GPU every two years do they not? Also, see above post and videos regarding VRAM usage.

Upgrading every 2 years is good thing and can be cheaper then play 4/6 years with same gpu.

[Bad 💀 Motha]

Upgrade every 2 years IS ridiculous.

If you do an initial build well enough, barely anything should need to be upgraded before at least 3 years.

For example if you have 8700K and 1080 or 1080 Ti, maybe you might want to consider an upgrade to a 3070 or 3080 depending on needs and what screens you have now or if you plan to upgrade those. But this kind of spec would still run everything extremely well enough. And if I was going to upgrade from a 6700K, 7700K, 8700K it surely wouldn't be anything Intel offers.

Someone going from a 1080 or 1080 Ti to any RTX 20 basically wasted their money.

[dOBER]

No its not. I didnt waste anything. Again:

Bought my 1080ti for 800€ and sold it 2 years later for 600€. Then i bought my 2080ti for 1100€ and sold it for 850€ 10 days ago. Which means i payed 450€ for 4 years. Strix 1080ti goes today for 300-350€ which means you payed more then me or same and i had 2 years a better gpu.

[Bad 💀 Motha]

IDK who the hell would pay 850 for a gpu that only goes for under 500 now.

All used 2080 Ti is worth now is below 500$ range
