Issue:
------

I recently purchased a MSI GAMING X GTX 1060 6GB without box and with one week checking warranty for 28500PKR. I got back home and placed the card in my build and noticed that my PSU don't have a 8-pin connector! So i purchased a 6 to 8-pin LEGIT connector. Ran the card and everything was fine next day which is today when i turned my pc on, i noticed a very unusual behaviour from my GPU! I am going to express this in points.

1. I started getting slutters while gaming and sudden lag spikes

2. Downloaded MSI Afterburner Monitored my GPU and CPU usage and found that whenever there are fast moves or heavy vegetation the GPU Usage drops down to 46% or even less!

3. GPU and CPU usage continously keed fluctuating.... get stable sometimes like when driving on an open highway with less things around

4. I launched GPU-Z and went on "sensors" tab and then started playing Vampyr and here's the screenshot after 5 mins of gameplay:

5. Temps never exceed 61*C

If you guys need anything else..... FEEL FREE TO ASK. Please help.. I am really worried!

1 - the 300W PSU will still be providing some power to the GPU via the PCIe slot.

2 - IT DOES NOT MATTER if you are using the Antec to only connect the to the GPU's 8-pin connector. The 6-pin connector and wiring from the Antec IS NOT DESIGNED to carry twice as much as its rated load to the GPU.

The 6 pin cable is specified to provide only up to 75W power. The 8-pin connector on GPU expects to be able to pull as much as 150W from that connector.

Your test is therefore not valid nor useful for diagnosing this.
