i am interesting to buy the Corsair AX1600i PSU is it worth to buy it/? for futureproof?

i will built new pc such us new cpu, include oc and custom watercooling in all the pc , gpu 4080x or 4090 lovelace , new motherboard next year with ddr5

for this i am asking is it it worth to buy it/? for futureproof?
also the Corsair AX1600i PSU is very good psu;

what is your opinion for the Corsair AX1600i PSU??

will the Corsair AX1600i PSU handle the new upcoming stuff next year??


the only thing that i am afraid is that Intel is trying to push that new 12v atx thing.

what it will happen to all psus in that moment??


if this happen the Corsair AX1600i PSU will not be futureproof?

Why buy it now? Wait until you build the PC, then it will be more clear how much power the new GPUs and motherboard require.
 
I got a 1000W as the new cards have high power spikes, an 850W would have probably been enough but it was £20 extra for the 1000W so got that to be safe. Also, if you plan on overclocking the power goes up fast.

for oc the cpu and custom watercooling in all the pc , oc the gpu 4080x or 4090 lovelace , new motherboard next year with ddr5 how much psu i need??

I got the 1000W because is should be enough for a long time(5+ years). As for the Intel 12v thing, PSU makers will supply an adapter of some kind if needed, that's what normally happens. I would not get a 1600W PSU unless you plan to use a 32+ core Threadripper with 2+GPU's and lots of drives.

Don't worry, reports say it may take a decade to transition! Save a couple of hundred quid and get a quality 1000W platinum, that Corsair is great but I would put the money into getting better performance when you do your next build.

What he said is more or less what i was going to say...............
 
if i will buy the AX1600i. will be fail when the ATX12VO will come out??


and all these people who bought new psus all these months?? what they will do?? they will have to buy again new psus with ATX12VO??

I wouldn't worry about it right here & now. I've yet to see any motherboards that support this new 12v standard. Nearly everyone who buys PC hardware with this ends up buying a new PSU anyway. Usual procedure is there will be a press release from the motherboard makers a few weeks before it goes on sale, compatiblity from PSU makers will be slow to begin with, then it will take a while for that compatibility to become mainstream. I'd sit tight & wait as this usually happens with a CPU release from Intel, with AMD not that far behind in this case.
 
i will build one new system in some months

cpu 5950 x oc

motherboard x570 oc


one rtx 3090 and later in the future i will put one second rtx 3090


32 giga drr4


soundblaster ae-9


2 ssds sata 3 2TB each

2 nvmes 2 tB

5 hardidks 8TB 7200 rpm

and oc cpu and gpu


Pumps/fans/etc for custom watercooling.. i will add one custom watercooling for all the pc


so what psu i need for all these things??

For all that and a dual 3090 setup :-


Corsair AX1600i

or

be quiet! Dark Power Pro 12 1500W



Anything less expect a headache with dual 3090s, this is coming from someone that has that setup not people guessing.

My setup here :- https://www.overclockers.co.uk/forums/posts/34846430/


Also if you plan to use the official 3090 nvidia Nvlink for the 3090s then you will need to buy an MSI Godlike x570 motherboard as it has the 4 slot spacing, no other x570 board has the correct spacing, but if you plan on using watercooling and have a 3 slot spaced board then you will need to buy the A6000 Nvlink with 3 slot spacing.

Read this :- https://www.pugetsystems.com/labs/articles/NVIDIA-NVLink-2021-Update-and-Compatibility-Chart-2074/


Above link explains the available nvlink bridges for 3090 and what will work or not.

Remember 3090s official bridge is 4 slot spacing and only the msi godlike x570 will do it, if you plan to use an AMD 5950x cpu, only other options with 4 slot spacing will mean a different cpu and platform.

We did this before here :- https://www.overclockers.co.uk/forums/posts/34939692/

You keep using a tool that is not correct and keep giving bad advice about systems that run dual 3090s and their actual power use when in situations the gpus cause huge power spikes, actual power use is not the problem, but the spikes are and as I explained before even a 1200w psu from a good brand can trip with a single 3090 and highend setup, funny enough Seasonic range have been shown to have a problem with 3080s and 3090s even their 1200w top range. Google the issue and you will see many such problems, also dual 3090s and his setup will basically need the psus I mentioned above because anything that you can buy lower than them is not going to work in a stable manner.

One thing the system boots another when stressing it with games or applications that hit the gpus and cpu hard. I learned the hard way too thinking a 1200w top end corsair would work and it didn't, it would switch off and then purchased the 1500 be quiet and no such problems.

At the wall the system pulls only 1000w-1100w-ish (system not overclocked, so you can imagine the power use when overclocked with 2x3090s oced and 5950x oced) gaming on a very demanding game with dual 3090s and will trip a 1200w, none demanding sli games were fine they would pull at the wall 800-900w and not trip the 1200w psu, but the fan on the psu will be maxed out and noisy too.

Other problem I had was with my work that would hit both the gpus and all the cores on the cpu, instant power off when I ran them.

When both gpus are not being used by a game or application that don't support sli/nvlink it would run one card only and be fine even when cpu and the single gpu was maxed but again fan on psu was noisy on 1200w.

Once I got the 1500w bequiet psu no such issues the fan hardly comes on when single gpu use and when gaming or using apps that used both gpus the fan would spin but not heard as it didn't need to run fast as the psu was not being hit hard all the time apart from the random spikes and they last no more than a second to 100th of a second, but on a psu that can't handle them spikes it trips the ocp or opp on the psu.


Watch this video :-



Then you will see the problem I state in the video and in the link I gave you on the previous reply here https://www.overclockers.co.uk/forums/posts/34939692/ as you see that site that was testing dual 3090s also had the same issue.

Basically what the op is wanting to build watercooled in the video below, mine is basically that system on air (My setup here :- https://www.overclockers.co.uk/forums/posts/34846430/ ).

No.

Even a top end gaming pc uses like 600w total.

The max I'd recommend is 850w. 1600w would be enough to run 3 PC's I'd imagine.

Depends on the PC

I can easily exceed your recommendation PSU.

intel i9 10980XE overclocked to 5ghz = 450w

RTX 3090 Kingpin overclocked = 520w
