Power supply dimension, change components.

[Dunder1]

Hello, Pardon my English (second language) and if it is incoherent.

First I wonder which dimensions the power supply has?

I have looked everywhere, do i have to physically measure the power supply?

Bought this PC pre-built, not good at tech and have never made a build or switched components.

On HP's site, my PC.

1. Power supply - No dimension, no name, only says "400 W Platinum efficiency power supply."

2. RAM - No name, just 16 GB DDR4-2666 SDRAM (2 x 8 GB) Assume the 2666 is MHz? Can I choose a RAM with higher Mhz? Any DDR4-2666 SDRAM fits?

3. Motherboard - After a long time on google I have come to the conclusion that this is the CPU?? (AMD Ryzen 5 3500)

The info should be more specific for non-tech's like me.

4. Graphic card - (good info) Nvidia ge-force GTX 1660 Ti

5. Graphics - Discrete. **bleep** is this?

Why I wonder is because of the compatibility for the parts if i plan to change.

I have been thinking of start to change RAM, but unsure which RAM fits my PC.

Last question... When you change part, do you have to fiddle with the software when you turn on the PC after the change?

My worst case scenario is that i get a matrix like picture on my screen, when starting the PC after a component change...

Thanks for answering!

@Dunder1 , welcome to the Community.

You have come the the correct place to get the information that you need.

Here is the Product Specifications page for the computer.  Here is the Motherboard Specifications page.  These two pages have all of the information that you need.

The motherboard in your computer is HP proprietary. It has a 4-pin power connector instead of a standard 24-pin ATX power connector. You will have to buy any PSU upgrade from HP.  HP has a 500W (L05757-800) PSU that is compatible with your motherboard.  Here is the PSU on HP PartSurfer.  You will have to contact HP Customer Support to see if they have this PSU available in your country.  You will have to measure the existing PSU to know the dimensions.

The RAM is DDR4-3200.  HP doesn't use XMP (Extreme Memory Profiles) in their motherboards.  They use the standard JEDEC (Joint Electron Device Engineering Council) memory settings.  So, you can't upgrade the memory to a faster speed.  You can upgrade to a maximum of 32 GB of memory using the specification in the section titled "Memory upgrade information".

A discrete video card is one that is installed in a slot on your motherboard and can be upgraded.  Integrated video is a part of the motherboard and can't be upgraded.  The GTX 1660 Ti is a discrete video card.

Here is a HP Knowledge Base article to explain what to consider when adding or upgrading  a video card.  Also, here is a HP Knowledge Base article to explain what to consider when upgrading the processor and/or memory.

This information should help you understand what needs to be done to upgrade your computer.  If you have further questions, please let me know.

Hi, thanks for your answer. Just a clarification about where you mentioned that my pc has DDR4-3200.

My PC has DDR4-2666…

That’s why I asked if I could choose a DDR4-3200 RAM when upgrading from 2666.

thanks for answering!

You are welcome, @Dunder1!

It states in the Motherboard Specifications in the section "Memory upgrade information" that your motherboard supports up to DDR4-3200.  I read it to say that this is what came with your computer.  The problem is, as I stated, HP doesn't use XMP's, so the best way to get memory that is DDR4-3200 would be to have it installed when you buy the computer.  Otherwise, the third party memory may not reach 3200.
