change of graphic card

[Nolax]

Hello, good evening, I would like to change the component in my PC (my graphics card and power supply) but I do not know myself at all, and I do not want to take a graphics card for the moment because I do not know the format of my pc and therefore I'm afraid the graphics card is too big or too small, can you advise me on the size of the graphics card and power supply that I should take? How big is my pc? (atx, mini atx etc ...) I put the exact reference in "product name"

Thank you.

what is the reason for upgrading for fun or gaming or 3d video rendering or what?

what can you not do now?>🤔

is a hUGE hint, we can  spend    GeForce GTX TITAN X 24GB SC GAMING $2700

GOAL matter most of all,  why spend huge money only to be not happy after?>??????😋

what is the upgrade purse? 

$100 or $500 ? a good card like GTX1650 (non SUPER) will fit and work and needs no PSU new.

no upgrade choice is so complex on any PC, (vast features sets on tap, look on newegg.com see?)

12makers of cards 10,000 cards  some fit some do not, only ruler answers that, measured, 🤔

HP does not document slot or fit sizes at all,  zero help there and is my job, (or if you took your PC to a shop theirs)

I can not see in side you PC now to see what is there first, PCs for sure desktops evolve easy. (so might yours or has)

• it has to fit and not hit things, inside, (length and height of card)
• it must not overload the PSU you have , not stated by you,.
• If over 75watt card you then need missing PSU GPU AUX cables now missing.

some 690 Hp has huge PSU for sale. even 500w... but that is out side my pay grade, nor documented.

your PC came new with 310watt PSU HP #  L64961-800

do you have $100 to $200 for new higher watt HP PSU.  , standard PSU  do not work. (see those 3 odd cables?)

that's it, but there are other problems possible if using UEFI Secure boot.  changing out GPU cards,  ask for help.

I want to change my GTX 1060 graphics card because it only has 3GB of RAM and it is too little to run Warzone for example, I would like to know what type of graphics card could fit in my pc for a budget of 250$  without having to buy a new power supply

Thank for your answer.
