RTX 4080 with a 750W PSU

[Chomiq]

I went after Chomiq, when? Are you referring to this?
Might I remind Chomiq that his Gold rated Seasonic PSU is better than OP's Bronze rated Corsair one.....

Does this qualify as 'went after'?

Nope.

I didn't have time to check/memorize every PSU model out there. Your comment on point.

I still have the PSU in the storage my Q6600 and the GPU were just fine after it blew up , i cant remember what GPU i had back then, was an Compaq prebuilt

the 80 Plus/Bronze/Silver/Gold/Platinum/Titanium ratings are efficiency ratings and not quality ratings.

I remember jonnyguru posting on here that it's possible to get a Gold Rated PSU that is crap from their testing.

My understanding is that the issue was fixed sometime in 2018/2019 with a platform refresh. The current Focus line does not appear to be affected.

Correct.

Are those still being sold? Corsair don't even list them on their website. And even when new they were only good for office builds.

Yes, they do. They simply don't advertise them as much as the "gaming" oriented units.

seasonic did "fix" the issue around 2019-2020 but any shopper would need to do their homework to see if the brand model is using the updated platform or just something they are clearing out that has been sitting in their shenzhen warehouse for a few years.

corsair lists them still on their web site although I do believe the CV line replaced them.

all the 80 plus rating system tells a person is the efficiency of the unit at a few various points at room temp testing

I believe most, if not all of us, here are aware of that fact. There may be differences in rectifier, filter (C Filter, RC Filter), voltage regulators, etc may be of varying quality. Hence, presumably Platinum and Gold rated PSU have better components and are able to handle quirks of a power hungry GPU like transient spikes and such. I'm no expert, but I'd feel better when I pop in a Platinum/Gold rated PSU into a new build, rather than a Bronze rated one, that's all I'm saying. OP can prolly run his rig with the new card with his present PSU, now whether that's advisable or prudent is another matter.

4k 120hz


Why is using bifurcated cables bad for the GPU?

Its not, bifurcated are absolutely fine

 

[maxfly]

The 4080 shouldn't trip ocp like the 30 series did as an aside. According to Ngreedia the transient issues have been corrected. The Antec should be gtg.

I have more or less the same problem, could someone help me?
I have this configuration:
MSI MEG Aegis Ti5 10th Gen - Intel Core i9-10900K, 128GB (64G*2) RAM, 2TB HDD + 2TB (1TBx2) SSD, Nvidia® GeForce® RTX 3070 (8GB).
Monitor MSI 2k 165hz or Lg oled 4k 120hz.

I would like to upgrade to an RTX 4080 (no OC). The PSU should be 750 watts.
MSI customer service told me I can do it as long as it's not an OC graphics card, but others tell me I can't because of the voltage.

My rig has RTX 4080 and 750W PSU. CPU is also on 100+W side. Working flawlessly.

 

[AnarquiaJoker]

Optimal! Do you also recommend a CPU swap or I can keep mine Intel Core i7-10700K?

 

[Darkholm]

It depends. If you are casual singleplayer like me where last squeezed FPS is NOT important - stay on i7. If you are in fast paced MP games, than it would be recommended to make a switch to Intel 13th Gen or AMD 3D V-cache solutions. Bear in mind that new platform is quite expensive so put on paper your gains in gaming and are they worth the shot.

I'm more of a casual gamer. I like action games and RPGs, I would like to put everything to the maximum without compromises but as long as there is at least 60fps even in 4k.

 

[Darkholm]

4K is GPU bound resolution so you are golden with your i7.

 

[Lei]

you will probably use bifurcated cables on your new GPU - that's not so smart.

Please say Pigtale. Bifurcated sounds so botanic.

Comments have convinced me and I'm getting an Antec hcg 850w gold.

No, get the gpu first, see your power draw.
Probably don't need it.
Or at least get 1000w

@Lei you are replying to 7 months old posts, mate

Moving forward at some point 11th Gen would bring you PCI-E 4.0 but unless you can source an 11700(K) at an obscenely low price prob not worth it and best waiting until you have the funds in the future for a platform upgrade.
