Clarification Request
While the 750ti isn't known for a lot of power use.

Let's hear about the old PC and it's parts. Specifically the make, model of the PC and the PSU (power supply.)

I did fix one last week where the owner had used some HDMI to VGA cable. That was non-functional and no, I can not fix what is not supposed to work. We plugged into some HDMI monitor and it came right up.

You didn't refute or tell me about your cable from the new card to the display.

Also, this PC used a motherboard connected video output. Tell the forum is both old and new video connections are dead when the 750 is installed.
Also, does the PC work without the 750.

https://forums.lenovo.com/t5/Lenovo-Desktop-Towers/K410-graphics-and-power-supply/td-p/1112707 finds the POWER SUPPLY is a measly 280W PSU.

That's small and could be the cause. I can't be sure but there are prior conversations where it is noted this small PSU will be trouble: http://www.tomshardware.com/answers/id-3562353/power-supply-support-asus-gtx750.html

Works fine without GPU

When the 750ti is installed, no matter where I plug in the VGA cable the monitor will enter power saving mode. Without the 750 the computer works fine.

I have used a Xenta LP4 Molex MALE to Serial ATA SATA Power Adapter to plug my 750 into the PSU (linked below). Not sure if this could cause issues

The PSU is not up to the task.

There are many discussions about trying to use this card on small power supplies. It's this or the card is incompatible with your PC. Be sure it's not a bum card. We have to test this card in another PC.

The card comes with a power cable.

Why are you using that other adapter you have listed above?

In fact I don't see how you can be using the adapter listed above.

My PSU was missing 1 cable that was needed to plug in the GPU, so i used a DVA cable to convert into into what i needed

If this fixed it. Always share so

When this fixes it, always share as I am running into folk that think these GPU power connections are optional.

Explain how you where able to use the adapter cable you listed above to power this gpu.

I don't see where either end will plug into the gpu.

Don't make up words or terms as no one will be able to follow you......dva?

I don't see how that cable will provide power to your gpu.

Your gpu should need a 6 or 8 pin power cable.

Explain how your doing this.
