Planning to upgrade psu on HP envy 750-514.. compatibility question

[TheVapeFather]

Planning to upgrade the 300w psu in my prebuilt 750-514 to a 750w so I can install a better graphics card (thinking 1660 ti), is this possible without frying the motherboard? I was researching the topic when I came across this comment

"Pre-built manufacturers (HP and Dell particularly) will very often swap a few of the pins around on the PSU headers for motherboard and CPU. If you change the motherboard or the PSU, you are putting yourself at a huge risk of frying one or both"

Which has made rethink upgrading until I get more info.

Is this something I should be concerned about with my particular model?

If not, can you recommend the best dimensions for a new psu that will fit in my case?

@TheVapeFather,

HP uses a standard ATX form.  Dell does not, in all cases.

The stock PSU is 300W. add the GTX 1660ti (120W) and you get 420W.  NVidiia has their specs on PSU. I have my own, and I would suggest that you get a Corsair 550W, like this semi-modular.   It is an exact fit.

Thanks for the suggestion, I like the specs on the psu you linked and will probably end up getting that one.

Just to be clear, in regard to the motherboard in the 750-514, there should be no issue changing out the psu because HP uses a standard form board unlike Dell which uses a custom board, correct?

@TheVapeFather,

No problem swapping out the PSU.
