New GPU Means New PSU?

[grant2698]

I just switched from my ASUS GTX 1060 6GB OC edition to a brand new GTX 1070ti directly from NVIDIA (literally got the card and switched it out yesterday). Gaming was originally working as expected, albeit getting both GPU and CPU temperatures higher than I used to have (around 70-85C while gaming, depending on which game it is). To remedy these higher temps, I went into the BIOS and changed my default fan setting from normal to performance, hoping to lower those temperatures to where they used to be. Unfortunately, this did not seem to help, as when I game my computer progressively ramps up to sound like a jet engine, at one point causing BF4 to crash in the middle of the match, sending me back to my desktop as if it was normal. At this point I am lost as to how I should fix this issue. One thought that came to my mind was that I have what I would think to be a semi-weak PSU for the components I currently have installed, and maybe that is causing an issue due to lack of power. I just did a full cleanup of my system as well when I installed the new GPU. Any help would be appreciated. (Also, side note, my GPU idle temp is 46C which, at least to me, seems a bit high. Maybe it is, maybe it isn't.)

my 1080 TI idles at 60C and peaks to 73C-84C,

so the 46C your'e getting is definitely low.

your PSU is a bit on the low end side as most 500W PSU's aren't the best.

But, if your computer is turning on and not shutting down randomly, then your PSU is just fine.

I'd say you're just fine and game on.

As for the PSU, the EVGA W1 is a pretty poor unit and I'd suggest replacing it before you end up possibly damaging that 1080 ti.

Keep in mind, the recommendations for a new PSU aren't to add discouragement but to help the longevity of your hardware as some weaker PSU's just fail on random notice, and tend to take other components along with them, such as the GPU.
