80 plus psu enough for RTX 3080?

Hi

 

I bought an RTX 3080 and need to upgrade my psu.

I'm currently debating between a Cooler Master MWE White V2, 750W (€65) and a Corsair CX750M (€94).

Is the €29 difference actually worth the upgrade from 80 plus to 80 plus bronze?

 

Do I even need a 750W psu for a RTX 3080 and 3700x or is it overkill?

Thanks for the help

Niel

Yes you need one, and i would even reccommande getting a better one on this kind of hardware. Why not go 80+ Gold?

Any Help is appricated! Please correct me if I´m wrong!

Sorry for grammer/spelling mistakes, but english is not my native language (it´s german in case you were curious) *expand to see builds*

 

Primary PC: CPU: AMD Ryzen 5 3600 | GPU: Crossfire Radeon 6870 + 6850 | RAM: CORSAIR Vengeance 2X16 = 32GB @ 3600MHZ DDR4 | MOBO: ASUS ROG STRIX B450-F | COOLER: COOLER MASTER ML360R | CASE: DEEPCOOL Matrexx 55 V3 ADD-RGB | PSU: GIGABYTE P850GM 80+ GOLD | SDD: CRUCIAL MX500 250GB |

Everything thats not colourful I haven't bought yet.

 

Secondary PC(Currently not operational): CPU:  INTEL Q8200S @ 2.33Ghz | GPU: GTX 750 ti / 760 | RAM: 4X2 = 8GB @ 800MHZ DDR2 OCZ Platinum | MOBO: ASUS P5E-VM SE | COOLER: Be Quiet! Silent Loop 280* | CASE: DEEPCOOL Matrexx 55 V3 ADD-RGB* | PSU: CORSAIR RM850 2019 80+ GOLD* | SSD: CRUCIAL MX500 250GB* | 

Everything marked with * is what I bought for the Primary PC and I'm just using it until I get all the parts.

Thanks for your reply.

 

As far as I understand these ratings only reduce the power consumption from the wall and don't affect the power they supply to the system. So is it worth it to pay an extra €13 for a Corsair RM750 (2019) to have a gold rating?

Why 750? Why not CX650M or the non M (cheaper). It should be enough for 1 3080.

The power supply rating isn't what affects the PSU compatibility with the 3080. Please refer to the PSU tier list for a ranking of PSU quality. I recommend tier A for the RTX 3080 due to the demanding nature of the card, and 850 watts due to the problems it has on lower wattage power supplies that would otherwise be appropriate for it.

 

The CXM is by all means a decent budget power supply, but you're clearly not building a low end or mid range system, not with the 3080.

I WILL find your ITX build thread, and I WILL recommend the SIlverstone Sugo SG13B

 

Primary PC:

i7 8086k - EVGA Z370 Classified K - G.Skill Trident Z RGB - WD SN750 - Jedi Order Titan Xp - Hyper 212 Black (with RGB Riing flair) - EVGA G3 650W - dual booting Windows 10 and Linux - Black and green theme, Razer brainwashed me.

Draws 400 watts under max load, for reference.

 

How many watts do I need? ATX 3.0 & PCIe 5.0 spec, PSU misconceptions, protections explained, group reg is bad

So if the rating doesn't affect it then why does it have to be A tier?

I don't know, there seems to be no consensus about what an 3080 actually needs.

The efficiency rating is what I was referring to. There are PSUs with 80+ gold that are better than some 80+ platinum units

What other specs than efficiency make them better?

Protections, voltage control, fan quality, and tons more things. There is a link on the tier list itself that takes you to a Google sheets page with the list's criteria for each tier.

Okay so that brings me to something like a Corsair RM850 at €130 which is fine but is double the price of Cooler Master MWE White V2, 750W.

Is it worth it?

 

If I were to use the cheaper one how would this translate in gaming performance?

it's not a matter of gaming performance, it's about stability and longevity. your FPS won't be affected but you could see crashes.

I see. So is there going to be a significant difference in amount of crashes?

Interesting! Thanks for the help!
So the psu quality doesn't actually affect fps in any way? Like could there be more stutters with a budget psu?

That's actually a fairly complicated question, but in this specific case, no I don't think so.

Nope. It's like the heart of the system - system either works or not. If a low budget PSU "dies" under load, it might take some components with it.

I edit my posts more often than not

Well now I'm thinking to just go for the cheapest option and if I experience crashes, I just send it back and buy a better one.

I woudn't do that. Get something good right away, it's the better option.

That would be a mistake.

 

You would be better off not even getting a 3080 at all, or not upgrading period if that's what you are going to do.

 

These people don't know what these cards actually take because they don't own one. Or how much power these cards really do pull and about the transient power spikes.

 

Just get the RM 850 and be done with it.

Is the psu quality more important with the new generation of gpu's than it has been with previous generations?

OH YEAH...

 

MUCH more so, these new cards are no joke, stable power and quality is the key here, and enough PSU wattage in the 1st place.

 

850W would be better so yeah the RM 850 will be fine.

Okay that might explain some of my confusion, in the past bronze was just fine.

Thanks, I will just go for the safest bet then.

Go for the RM. How much is the rmx? it has more quiet fan so rmx750w would be wiser noice wise.

 

Effiency and brand is not quality. LLC and DC-DC with decent voltage regulations and protections tell a lot about quality. There is ripple and nocie  factors too + others that i did not think of.

QUOTE ME  FOR ANSWER.

Tier lists for building a PC.

 

Motherboard tier list. Tier A for overclocking 5950x. Tier B for overclocking 5900x, Tier C for overclocking 5800X. Tier D for overclocking 5600X. Tier F for 4/6 core Cpus at stock. Tier E avoid.

(Also case airflow matter or if you are using Downcraft air cooler)

Spoiler

 

Gpu tier list. Rtx 3000 and RX 6000 not included since not so many reviews. Tier S for Water cooling. Tier A and B for overcloking. Tier C stock and Tier D avoid.

( You can overclock Tier C just fine, but it can get very loud, that is why it is not recommended for overclocking, same with tier D)

Spoiler

 

Psu tier List. Tier A for Rtx 3000, Vega and RX 6000. Tier B For anything else. Tier C cheap/IGPU. Tier D and E avoid.

(RTX 3000/ RX 6000 Might run just fine with higher wattage tier B unit, Rtx 3070 runs fine with tier B units)

Spoiler

 

Cpu cooler tier list. Tier 1&2 for power hungry Cpus with Overclock. Tier 3&4 for overclocking Ryzen 3,5,7 or lower power Intel Cpus. Tier 5 for overclocking low end Cpus or 4/6 core Ryzen. Tier 6&7 for stock. Tier 8&9 Ryzen stock cooler performance. Do not waste your money!

Spoiler

 

Storage tier List. Tier A for Moving files/  OS. Tier B for OS/Games. Tier C for games. Tier D budget Pcs. Tier E if on sale not the worst but not good.

(With a grain of salt, I use tier C for OS myself)

Spoiler

 

Case Tier List. Work In Progress. Most Phanteks airflow series cases already done!

Ask me anything :)

RMX is another €20 more expensive than just a RM one.
The RMX750 is the same price as the RM850,€130.
