Have I chosen the right Power Unit for my planned computer set up

Hi,

I am planning for my next computer build and would welcome your comment especially on the Power Unit and if it will cope - my last set up indicated a total of 700w, I bought a 850w Fractal design that worked for about 2 months then gave problems that was only resolved when I changed to a 1000w.

I have tried several sites that suggest power units, but they do not appear to have kept up with modern components and nearly always return a power well under what is needed and obvious to anyone who has built / thought of building a computer.

My planned set up:

Case: Thermaltake CTE C700 Air

Fans: Six Thermaltake CT140 fans - 3 ARDB and 3 Non-ARGB

CPU Radiator: Thermaltake 420 TH420 V2 Ultra ARGB CPU sealed water-cooled radiator.

Motherboard: Asus Intel Z790 Pro Art Creator

CPU: Intel i9 14900K

GPU: PNY Nvidia a4000 running two 27inch monitors and on 9inch (part of my current set up and will be transferred.

Memory: Kingston Fury Beast DDR5 PC5 44800 5600MHz 32mb * 4 modules

NVM PCI Samsung Pro 1TB M2

Two 4TB HD 72000 rpm

One 2TB HD 72000 rpm

One Aquacomputer OCTO - fan control, Case temperature monitoring - 4 probes

One Aquacomputer HUBBY - USB 2 expansion unit.

The Power Unit I have identified to power the above is the Thermaltake Toughpower GF3 Snow 1200-Watt PCIe Gen5 ATX 3.0 80+ Gold.

Many thanks for any advice and help you can give.

Hello MickJJ,

 

1200W is rather more than what you need both to support your list of parts and to be paying for.

 

The proposed GPU which is the most determining factor is a relatively low powered card with the next in line for power draw being the CPU and even taking those two into account you are only looking at 500W of good clean and stable power.

 

Thermaltake are not a brand that I use or recommend and because most of them are below par, the Snow unit is an exception so it is unfortunate that it is way more than what you need, allowing for your additional components 750W would have you covered but for future proofing I would suggest either the 1000W Gold efficiency rated example here or the 850W Platinum unit here

Hi phillpower2,

Thank you for your quick reply which as you may recall from previous posts over the years I will follow up on.

When I formulate a list of components each month (until I have saved up sufficient funds to pay for them) I not only check up to date prices, code numbers but also compatibility. 

Regarding the above list both Microsoft and Asus identified compatibility with each other, and RAM chosen. Today they still identify RAM compatibility but only Asus maintain compatibility with the chosen CPU, validated since BIOS 1203. It is no longer identified on the Microsoft compatibility chart. I may have to look at the ProArt Z690-CREATOR WIFI.

Many thanks

Note My build is not for any other reason than I enjoy building and have done so every three or so years and my requirements have not really changed Photo and Video editing, multitasking, and now wanting to enjoy the benefits of AI technology. Until now I have gone down the Xeon and EEC route.

Microsoft have no bearing on this other than your CPU post dates an 8th generation Intel CPU and is therefore compatible with Windows 11 and the Trusted Platform Module ( TPM ) requirement.

 

Something to keep in mind for the future, a CPU must be compatible with a MB whereas the RAM has to be compatible with both the CPU and the MB, this because a MB can be compatible with faster CPUs than the one in your list of parts and MB manufacturers often state RAM speeds that far exceed that which any compatible CPU that the board can handle.

 

You are welcome btw  :)

 

Edit to add: Being that the OPs initial question has been answered rather than leave the thread hanging we will mark the thread as answered and therefore no need to ask for any update.
