Hello people I think I have a problem with my Psu. My pc has been Crashing and auto rebooting for the last few months. Its only when I am on high load 30%+ on the gpu and cpu. The psu is a Thermaltake Smart RGB 700W (230V) 80 plus. Do you guys think its a psu problem or something else?

The first place I would look would be heat dissipation on the CPU.

I run a 750w PSU, but I have a GTX-1070, liquid cooler, and six hard drives. I likely pull more power than you do. I would first look at heat issues on the CPU. Look to see if you can find an app to measure the temp of your CPU first.

If it's a heat issue. You might be able to just reseat your heatsink / fan (with fresh thermal compound) and all is well again.

On the PSU side: What is your PSU's 80+ rating (you only mentioned it's 80+ so then it could be White)? It should be at least Bronze if you run above 600w. I'd go for Gold 550w over White 600w any day of the week. I doubt your config even needs more than your 700w (TBH, I think a 600w may be fine), since your video card is the only big draw and on 30% load, it will probably draw under 100w. That 80+ will may well determine if it's handling the demand.
Source: see my specs below (except GPU OC'd a little by the OEM), 8 fans total, and I actually have 2x 3.5" 6TB HDDs (one is purely a backup). I'm on a 550w 80+ White and I'm fine with my PSU, even when encoding video/rendering 3D. The major difference between our rigs is your video card, which is only hitting 30% load (about 70w), putting it around my card's power anyway. You have an extra 150w compared to me.

On the CPU side: How long does that temperature (65-75 C) remain? I'd stress test it for an hour (during which time you can see if it reboots). Try running Passmark's Memtest, too. Just in case it's memory-related (could be on-chip controller for example, not necessarily dies).

It could be down to other thermals, too, like your PSU's. Check everything coz the CPU can be kept cool at the expense of Memory temps for example. Airflow that pushes past components can cause dust to settle on things that usually don't need fans because dust will trap heat between the fins of heatspreaders etc. Dust is an enemy of rigs like ours that have lots of fans/airflow. A can of compressed air does wonders.

If the MB shows signs of dust then there could also be a dry joint problem [this is where dust and/or damp cause electrostatic corrosion on the terminals] causing intermittent interference [ram and additional cards are most susceptible] the answer is to carefully remove them and wipe the contacts with a CLEAN LINT FREE cotton cloth being careful not to damage them] and re-install
