NVIDIA 4000 Series

[Stu999]

Nvidia announce partnership with <insert car maker/mobile phone company here> and nothing about 4000 series.

That would be funny. I’m happy to look foolish, gotta give the forums some laughs.

Edit - re-watching the video and just getting to the bit where he says 30 series cards aren’t necessarily going to drop in price, weeks before they were slashed in price

hope its decent. some of the new msi power supplies even though gold are **** . read reviews. hopefully you got one of the good ones.

MSI MPG A750GF Power Supply Review

MSI did a far better job than Gigabyte in its PSU products, but is this enough?

www.tomshardware.com

Linus Tech Tips has a PSU Tier List and the guys that created it left and have a website now with an updated one. The A850GF unit is top tier according to them.

PSU Tier List rev. 17.0g - Cultists Network

PSU Tier List will help you to choose the best PSU out of hundreds of models on the market. From budget to the highest end Power Supplies.

cultists.network

Though the AGF units are not single rail, they are multi-rail so no idea why they are in the single rail list.

Noted: [11] Ball bearing fan, possibly not silent even at very low RPMs.

Relatively new platform with no proven track record (but reviews are good and the OEM is very experienced)

Can’t imagine anyone with a 850W or higher PSU is going to struggle with the new cards, IMO of course.

4090 can draw 660W its rumours. that doesnt leave much from 850w for your cpu and anything else. Plus never good to be running at such a high percentage of the PSU max, I always aim for 60% or less normally.

That's fine. Maybe AMD want's my money.

Do you please have a source I can read for this statement that running a PSU at higher percentages is harmful?

1080P looks pretty great at 21.5 inches actually.

Yeah it's pretty clear on my 24" BenQ, and even the 29" 2560x1080 that I have. It's just the new 27" 4k monitor doesn't play nicely with 1080p

Don't listen to that, it's anecdotal - it's like saying running a CPU at 90c is harmful. Like a CPU is designed to even run at 95c, a 850w PSU can run at 850w and even a bit higher than that and will do so for many years no problem.

Running a PSU at 60% is where it's most efficient - meaning that the percentage of power it takes from the wall and can convert to output for your PC components is at its highest and going above 60% load, that's efficiency drops but this doesn't hurt or damage the PSU, it can and will run at 100% load no problem

Fair point but I meant generally, and generally most people won’t be opting for a 4090 or above.

Truth. Decent models are rated and tested at (simulated) 100% for years.

The price of the 40 series is going to be £LOL. It has been for ages $1 = £1 plus a bit more (compared to US retail prices) when the pound was higher than the dollar so who knows what it will be now.

One-for-one plus 20% VAT is my guess.

Or more.

Hopefully Gibbo hasn't run out of cake.

It's going to be hilarious.

I’m not convinced it’s damaging in the lifespan of the average psu unit but I’ve read that running at close to your PSUs limit is less efficient. So it’s less costly and consumes less power to run an 800w psu at 400w than a 500w psu at the same 400w.

I can imagine you probably do put more heat/strain on the parts running them closer to their wattage limits though. likely dependent on the quality of components used in the psu itself as well.

 

[GAC]

speaking of power requirements i wonder if the 4090 and even 4080 will require pcie 4 or even 5 due to power draw. im talking through the pcie slot itself.

 

[gpuerrilla]

Your not meant to run at the limit all the time no. However each unit has a sweet spot of efficiency, if you check the manual or the graph on the side. Better quality ones will have less losses so if you plan to run the machine 24/7 better over the long term.

So it’s less costly and consumes less power to run an 800w psu at 400w than a 500w psu at the same 400w.

Really?

For a decent 80 Plus Gold/Platinum/Titanium certified PSU, even at 100% load, the difference from 50% load is 4% max. For 80% load (400w from a 500w supply), the difference is non-existent. In fact, for the Corsair/Seasonic efficiency curves I've just looked at, the efficiency actually improves all the way up to and beyond the 80% load level (usually peaks around 90%), so a 500w unit actually ends up being more efficient than an 800w at 50% load.

 

[Frenzy]

Have people realised that psus are built differently with different efficiency's due to different components so one statement about running x at a certain percentage is too general and sweeping? lol Swear people just like to argue on here.

I think these ideas are a few years old and pre-date the newer supplies with the higher 80+ ratings that we have these days. They used to be right, and I think it's just one of those ideas that become almost superstitions and won't die, plus of course over-provisioning power never actually hurts any system so ...

Correct. The old myth about over-speccing your PSU for the sake of "efficiency" has been debunked so many times now. No point wasting money that can be put to much better use elsewhere in your system, as Steve at GN has long argued.
