Looking inside is a great idea, and easy. I'll edit my post above.... it looks like there is a shorter and a longer power supply for that computer, and the longer would be the 310W max TDP one.
The searching was difficult but here is the part number for the 310W version: 922458-001
In the HP Parts Store I came up with this, screen shot:
So, it would be a purchase from HP of only about $60.00 USD, plus shipping.
The HP power recommendations are conservative, and you've proven your workstation can run the card, but I would not keep doing that with your current power supply. It will overload and fail eventually. I'd buy the 310W version and install it, or have a shop/HP install it.
If you look in the first document I linked to in my post above, and search for "310" you'll see that some of the video cards only are recommended by HP to be used with the 310 watt PSU. You're clearly in that category.

When I look up your specific 1KN89EA HP shows a "HP ProDesk 400 G4 Microtower PC (1KN89EA)".
That general series of desktop PCs has 4 form factors, and your "Mini Tower" version is the largest. Thus it would have the capability of taking the highest capacity power supply. Yours will only have one power supply at a time (either the 180W or the 310W PSU). The next smaller capacity PSU in that series of PCs would be for the "Small Form Factor" version.
EDIT: Some added research found the 310W PSU to have Spares P/N of 922458-001, and that is a longer version than the 180W PSU. Width and height would be the same, I assume, with the higher capacity coming by being longer. There is a YouTube video of unboxing your type of PC, and the inside is shown with the 310W power supply in place.
You need to do some research on the power that your desired video card draws, and the amount of power that HP allows for a video card in your MicroTower. Your desired nVidia card's specs recommend at least a 300W power supply (so that looks good). I'm quite sure you can pull this off.
Get this version 27 of the QuickSpecs:
http://www8.hp.com/h20195/v2/getpdf.aspx/c05373442.pdf?ver=7
Page 8 of that document states there are two PCIe x16 graphics slots with one wired as a "x4" (number of electrical lanes only 4, but the other one will have 16 electrical lanes). You want to put your video card in the x16 slot with 16 lanes, and printing on the motherboard right next to the slots will tell you which is which. The white one has lower x4 capacity, and the black one is full x16 capacity. By convention PCIe x16 slots that are not downgraded like the white one will provide up to 75W to the card from the slot itself, and thus the black slot can power your desired card fully. I don't think your card will have a supplemental power receptacle because it only draws 75W max (most of the time it will use significantly less).
Make sure the size of that video card can fit in your box.... see the dimensions in the spec source below. All versions of this card take two slots width, from any of the vendors. However, make sure you don't get one that is too long for your specifications.
Here is your card, and go down to the bottom and look at the link for full specs there:
https://www.nvidia.com/en-us/geforce/products/10series/geforce-gtx-1050/
I have always liked the EVGA versions of the nVidia GTX cards.... they have treated our family well for home use. For business workstations our company uses Quadro cards only.
Get all of the HP manuals for your computer from here:
https://support.hp.com/us-en/product/hp-prodesk-400-g4-microtower-pc/15292287/manuals
Don't try to jam much more in there..... SSDs need less power than HDDs, and you really should be booting and running your applications from a SSD to compliment this video card properly.
