@omenuserv2133,

The good news is that ANY RTX 30xx series will fit/work in your [4NN43AA] OMEN By HP Obelisk Desktop 875-0034 (HP 84FD Edoras motherboard) as shown here by super users: UserBenchmark: HP OMEN by HP Obelisk Desktop 875-0xxx Compatible Components.

However.

Your stock 500 watt HP L26279-800 power supply is the bottleneck here.

The other good news is that your motherboard is compatible with a standard industry 24-pin ATX power connector. As long as the power supply's dimensions fit, any industry standard ATX PSU will do. I don't know exactly what the dimensions are for your power supply -for whatever reason searching for the physical dimensions of your 500 watt HP L26279-800 power supply came up empty. 

But let's say the dimensions of your current power supply are 150 mm (5.9 ") x 87 mm (3.4 ") x 140 mm (5.5 ") -again, you will have to measure it yourself, but the point is that ANY standard ATX power supply you can find having the same dimensions as your PSU, will work just fine.

Personally, I prefer a fully modular PSU. These power supplies are far less 'messy' in that you can use/plug in only the power cables that your desktop needs.

In any regards, if you want to stick with your 500 watt power supply, you will be A-OK up to an RTX 3050.  The RTX 3060 would be iffy, as Nvidia recommends a PSU with a minimum of 550 watt. Your 500 watt PSU may be good enough, but be forewarned that you might see the occasional down-throttling if the RTX 3060's power demand is spiking.

[EDIT:] Not all RTX 3050 graphics cards -or any other RTX 30xx cards for that matter, will have the same dimensions.  Some are rather compact, other models with three cooling fans for example, are considerably larger.  You'll have to carefully measure inside your desktop and determine what will actually fit.

Hope this was helpful.

Kind Regards,
