Okay, thank you for replying back. Much appreciated.The Antec HCG 750M is a good PSU made by Seasonic. Older platform , but still a decent PSU. Yes it's fine for upgrades , has plenty of power.
NO, I don't have issues whatsoever. I was just worried about my power unit. I thought, if I upgrade, then maybe my current power won't be enough. But, Thanks for your assurance. Much appreciated. I really don't have the cash to spend on a new mobo/PSU/CPU......I just want to upgrade my GPU.Yes, your power supply unit is okay, but NOT the very best, since it falls slightly under the lower TIER category on the PSU hierarchy list. It's an average quality unit by ANTEC, but it's not that bad either, IMO.
The actual AMP rating, depends on the exact Video Card model/brand, and manufacturer. Do the math. On your current PSU model, actually there are a pair of 12V rails.
Each are rated for 40A each, which gives a combined output of 62A or 744W. It's a multi-rail unit. So I think you should be fine, with your current power supply, if you are using the GTX 970 GPU, or some other GPU, unless you are facing some serious issues with your PSU under Heavy Gaming/load. In general, for most of the GTX 970 cards, the requirement is a minimum +12V current rating of 42A, but this also depends on the custom model as well.
On your current PSU/HCG-750M, there are 2 +12V rails, and so the total combined output rating will be 62A, or a total of 744W, which is enough, at least in my opinion.
Make a note though: The total wattage number of any PSU is not always really the most important deciding factor, primary concern is the 'quality' of power it produces, and the total capacity of the 12V source etc. Though how the rails are laid out does not affect that much, i.e. single/multiple +12V rail PSUs.
Multi-rail PSU can be mildly better, especially with high wattage units, but it won't have any impact on your performance. However, it can provide an extra layer of safety in case you get a short circuit. A multi-rail power supply has OCP on all +12V rails, ensuring that your PC components stay alive, if a problem like a short circuit occurs.
Hope this helps ?Are you facing any issues with this PSU ??
That RTX GPU is definitely faster than the GTX card, but only buy it if you want to play any RAY TRACING game. For 1080p/60Hz, the GTX 1660Ti seems to be a much better option, IMO. Though, if you have the cash to spend, then you can grab the RTX 2060.Btw, which card would be a worthy upgrading to, GTX 1660ti, or the RTX 2060 ?
Okay. I'm actually stuck in a dilemma. I'm not that much interested in ray tracing, but if that RTX GPU is worth buying, then I might consider it. Some eye candy, yes ? But isn't ray tracing just a fancy gimmick ? If there is a huge PRICE diff between these 2 cards near my location, then the GTX 1660Ti would be my choice for now. I will let you know soon though.That RTX GPU is definitely faster than the GTX card, but only buy it if you want to play any RAY TRACING game.

But I don't think it's worth buying an RTX GPU, given how few games have support for RTX.. The performance gain is surely there though, even in non-RTX PC titles. You need to decide what suits your budget
Nope. It's not a gimmick though. It's an industry standard CGI. It is pretty much in it's "infancy" stage as well. RTX won't be becoming mainstream anytime soon. Modern GPUs these days don't have enough horsepower to ray trace the entire scene, in a single frame, by rendering physically accurate reflections, refractions, shadows, and indirect lighting.. That's why it comes with a performance loss.But isn't ray tracing just a fancy gimmick ?
