[obaiamr139]

i have a HP Pavilion Power Desktop - 580-002nt and i want to change my graphics card from 1060 3gb to 

1070 or 1070ti  or 1660ti or 3050 

which one of this is capable  for my pc

@obaiamr139,

Do you mind confirming your power supply wattage (either 300 watt or 180 watt)? -Even better, what is the part number on your existing power supply.

Its 300

@obaiamr139,

All right, thank you.  Not the first time that online information for HP legacy computers is challenging to dig up.  So, your power supply is the 300 watt p/n: 859758-800 or 832005-001, and your existing GPU is the OEM HP NVIDIA Geforce GTX 1060 3GB GDDR5 (p/n: 909616-001), powered through your PCIe X16 slot and a 6-pin PCIe power connector.

Your question requires some thought.  To be honest, this desktop is underpowered. 300 watt? -that limits your options. And is also restrained by the 6-pin PCIe power supply connection. According to HP GTX 1060 OEM Specs | TechPowerUp GPU Database, your OEM HP GTX 1060 has a max TDP of 120 watt.

For example, a Gigabyte GeForce GTX 1070 Mini ITX OC 8GB GDDR5 requires an 8-pin PCIe connection and a minimum 500 watt PSU as per manufacturer.

Researching.  -Stay tuned.

@obaiamr139,

The OEM HP GTX 1060 3GB is the best GPU your desktop can possibly power without (major) graphics stuttering or down-throttling.  In order to meet the needs of a higher end and better performing graphics card, you'll have to invest in a more powerful PSU, starting at 650 watt in my opinion.

And there's good news:

You see, 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. As far as I can tell, the dimensions of your current power supply are 150 mm (5.9 ") x 87 mm (3.4 ") x 140 mm (5.5 ").

Doesn't hurt to verify these measurements, please, as a replacement PSU should have about the same dimensions.

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.

[EDITED:] Here are just two of many examples of a semi-modular and a modular 650 watt power supply which have the same dimensions [50 mm (5.9 ") x 87 mm (3.4 ") x 140 mm (5.5 ")] as your existing power supply, semi-modular: https://www.amazon.com/Corsair-Bronze-Certified-Modular-CP-9020103-NA/dp/B01B72W1VA/ref=sr_1_8?crid=... and fully-modular: https://www.amazon.com/Corsair-CX650F-Bronze-Modular-Supply/dp/B08FVFDYFD/ref=sr_1_11?crid=2RI0H1S7C....

When you do upgrade your power supply as suggested, you could easily power an RTX 3050 such as this one here: MSI Gaming GeForce RTX 3050 8GB GDDR6 128-Bit HDMI/DP PCIe 4 Torx Twin Fans Ampere OC Graphics Card ....  Check if this card's dimensions: 278 mm (11") x 49 mm (2.0") x 130 mm (5.2") will fit inside your desktop without hitting your RAM or other unmovable motherboard parts.

Hope this helps.
