Hi there, I am new to PC building and have been doing a lot of research to configure a high end compatible and faultless PC.
My build includes-

-Hyte y70 touch case.
-corsair dominator titanium 2x32GB 6600 CL32.
-Z790 apex x encore motherboard.
-intel i9 14900K processor LGA 1700.
-samsung 990 pro PCI-e 4.0x4 ssd.
-lian li galahad 2 trinity SL INF AIO.
-lian li uni sl120 infinity triple x2/x3 (6-10 fans in total).
-Zotac GeForce RTX 4090 Trinity OC White 24GB GDDR6X PCI-Express Graphics Card.
-1200W ROG strix power supply.

My main question is if this spec is all compatible. And also the power supply if 1200W is enough to cover all the components noted above.
Some advice and help would be greatly appreciated.

Thank you.

Is the PSU the newer Aura ATX 3.0/PCIE 5.0 model? If yes, then you're fine, though I note from your spec you have an extreme overclocking motherboard and the power consumption of the 14900K can be very large indeed under these conditions. That said, you wouldn't be using the graphics card to max (or hardly at all, I assume) while you're overclocking, so...

Say 250w for the CPU, 550w for the graphics card and another 75w for everything else, so in a worse case, full load multi tasking scenario. 875watt.

1200watts is OTT for desktop use from an efficiency point. Under heavy workloads 1200watt it’s about ideal. For gaming probably on the lower end of the efficiency curve. Overall not a terrible choice.

Hi there, thank you for super fast response. The PSU is an asus 1200w ROG THOR platinum II. Sorry not a strix. I design 3D models for manufacturing using Rhino/Matrix/zbrush/ Keyshot and also other rendering softwares to enable customers to view products/designs before getting the go ahead to physically manufacture their designs.also will be used for gaming 75% work 25% play.

Hi there thank you for your super fast response also! I went on to a computer calculator website to figure out the wattage i would use but got confused. I think i would be on the fence of 1000W but a bit unsure, so i thought 1200W would cover myself. Is there anythibg in this build you would change for better performance/resilience/peace of mind?
Thanks again
 
So for the PSU a Seasonic prime 1000w platinum or titanium. That’s assuming this is more a gaming focused build rather than workstation. If the system is going to be used for prolonged heavy worked loads inc the GPU then a higher wattage Seasonic PSU.

The only other point is the questionable reliability of an AIO.

Thank you. I think to stick with 1200W only because i am such a noob and impulsively purchased one thinking it is what i needed for my set up. So if you think it will work well then I will keep it. I also purchased the DDR5 dominator titanium 2x32GB 6600 so will have to build around these. I will be using it for quite demanding work.

I have not purchased anything else yet thankfully. Is it my choice of AIO? Or AIO in general will be questionable with the build i have chosen?

I am super grateful for all of your replies, this is rare in most forums

I’ve never used any ASUS brand PSU and 1200 watts isn’t a bad choice at all. I recommend Seasonic as they’re pretty much the Rolls Royce of PSU’s and I’ve never had a single issue with a Seasonic. The ASUS PSU could for all I know could be very good quality. I just have no experience with them personally.

I’ve had a lot of failed AIO’s and now avoid them. A company called Asetek was granted a patent and and sued anyone not licensing its design which killed development. Swiftech had some good quality units but I haven’t seen those in the U.K. for some time. Again, I’ve very little recent experience of AIO coolers so can’t really help. I go highend air or full custom water if the heat output is beyond air cooling or I’m building a super low noise system.

Ok that sounds good it was very helpful. I will go high end. I will do some homework and narrow down some options both air/water cooled systems. I think I will keep my spec as listed originally, but swap out the AIO for a better one. Thank you again

You’re welcome, sorry I can’t be of more help. I know @Journey builds systems professionally. He’ll probably have much more insight.
 
I think one of the questions I'd ask is why are you spending £280+ on a PSU, but only buying a PCI-E 4.0 SSD? The Thermaltake Toughpower GF3 TT Premium 1200W (Fully Modular PCIe Gen 5 ATX3.0 80+ Gold PSU) is less than half the price and Tier A rated, and has a 10 year warranty and is built like a tank.

What is your end goal with the system, as it looks like spends as much as possible in one go with no reason other than the parts are expensive.
