I wouldn't normally post here because i am pretty well educated with the pc side of things, but i have a hp prodesk 600G1 with a 320w cpu, paired with a i3 4130 which is of 54 watts, and as for adding a graphics card that will be powered on the pci-e lane only or a single six pin using a molex adapter, which is my best choice.

i have been looking at the gtx 750ti, rx 560 or the 1050ti the varients that can run on pci-e only

i know my options are extremely limited by power draw, but is anyone able to help me with a configuration?

Yes, your CPU can definitely handle the GTX 1050 Ti, just not as well in CPU demanding games such as GTA 5, or Battlefield 1. The GTX 1050 Ti is rated to run at a power supply of 300W, so your 320w PSU is most likely able to handle that card.

If that's one of HP's oddball non standard computers, I'd be more concerned that the pci-ex slot on the motherboard might not output a full 75W. Also, you might need a small low profile card. You'd probably get a GT 1030 to be an almost sure thing to work in that as is.

Assuming you wanted a more powerful card, and assuming you won't get 75W out of the pci-ex slot, then you're better off with something like a 1050 Ti that needs a 6 pin connector. Use a Molex adapter, and then the 6 pin can supply the extra power to make up for the pci-ex slot if it's inadequate.

The 1050 Ti is the most powerful card you can get without needing external power. Some models will implement a single 6-pin for overclocking headroom and for stability, in case the PCIe slot cannot provide enough power. So if you can afford it, go for the 1050 Ti, it has the highest performance/watt out of all the cards that you mentioned.

so considering both of your answers, using the 1050ti with a molex adapter you would rank as your best answer in this picky scenario im in? just incase the pcie port dosent keep a stable 75w, the molex keeps that stability going should there be a lack of wattage in the pcie lane and the final point i wuld like to addres is the fact that with the current specs of the i3 4130 and other standard pc components the "oddball psu" rated at 320w woudl run a 1050/ti
