Upgrading GTX 970 on HP Envy 750-175se

Hi, I'm planning to upgrade my GTX 970 to a GTX 1660 on my HP Envy 750-175se.  I'm worried that there will not be enough space for the actual card itself.  Can someone confirm if the 1660 can fit into the case?  Also, will a 500 watt PSU be enough?
I have an i7-6700 3.4ghz, and 28 gb ram.

@qweasd602,

Graphic cards vary in length. Measure you existing GTX 970, and allow for variation.

The GTX 970 is a 145W card (2x6pin power), the GTX 1660 and GTX 1660Ti are 120W cards (1x8pin power). While NVidia states a 5.7" length,  some cards can exceed 9.3".  A GTX 1660 is 23% better, a GTX 1660Ti is 44% better.

I just measured the length, width, and height of my GTX 970.

Length: About 250 mm/ 10 inches

Width:  About 105 mm/ 4 inches?

Height: 40 mm/ 1.6 inches

With these measurements in mind, will any variations fit this size category to replace my GTX 970?

Edit: I am also thinking about the RTX 2060/2070.  Are there any sizes that will also fit these dimensions and will my 500 watt PSU be enough for the RTX 2060's 160W, or the RTX 2070's 175W since they are only about 15W/30W more?  

I will be using an Intel Core i7-6700, 28gb ram, a 1tb SSD, a 7200 rpm 2tb HDD, and also have an optical disk drive.

Also, about the PSU pins for the GPU, are there adapters that can convert a 1x6pin to a 1x8 pin? 

Thanks for your reply.

@qweasd602,

Your learning curve would be better served if you did the research.
