Please help! I suspect PSU issue but im not sure.

Hi!

As you suspect, the PSU, seems to be the problem.

Do you have the possibilty to test with another PSU or to test the PSU using one of these?

500W should be more than enough for your system, so the issue isn't that the power is to low.

Hi, thx for the answer! But 500W is enough even when i have 1 SSD, 2 HDDs and 1 external plugged into the system? Nvidia's site recommend 450W minimum for GTX 660 Ti, that's why i suspect PSU wattage rather than the PSU itself. PSU has almost 1 year of usage, not much, i think.

And this problem came into being after i installed GTX 660 Ti.

But ill consider your suggestion.

A decent 500W should be more than enough. Your system will use about 360W from the wall so the power should be enough.

I would still strongly recomend that you test you current PSU or if it is simpler, test with another one instead.

If you are going to buy a new one, I would recomend a PSU that is at least 500W Bronze certified. One year isn't much, I've had my Fractal Design 1000W for about six years now and it's still working like a charm!
