Upgrading to external power supply from internal tfx stock psu.

[Jeeg]

I am wondering what is the best way going forward to upgrading the stock psu to something to at least a 400w or 450w psu, I currently have the stock 310w psu (TFX Form factor). I am hoping to upgrade the gpu to a GTX 1660 and for that I need at least a 400w psu. What can I go about to upgrade the psu.

@Jeeg , welcome to the Community.

Your motherboard is HP proprietary.  It has a 4-pin power connector instead of a standard 24-pin ATX power connector.  This means that you will have to buy a PSU upgrade from HP.  They have a 500W (L05757-800) that will work with your motherboard.  Here it is on HP PartSurfer: https://partsurfer.hp.com/Search.aspx?searchText=L05757-800

You can order it by selecting "Add to Cart".  You don't have any other option since we haven't been able to find an adapter anywhere on the Internet.

Here is a Power Supply Cross-Reference Chart that will show you where I got the information: https://h30434.www3.hp.com/t5/Desktop-Knowledge-Base/Power-Supply-Cross-Reference-for-specific-model...
