Need help with PSU temps

I have a lot around the internet for a clear answer and I have not been able to find one. My PSU idles between 41-50c depending on the season, and runs at 69-75c when gaming. I accidentally blew up my last psu after not researching enough on how many watts it can put out before shoving a GPU in accidentally setting the graphics to ultra and playing Shadow of Mordor for about 4 hours at which point it put on a lovely little fireworks show, dying, frying my motherboard and damaging my cpu which in total cost $350 to fix, because I also don't have a second computer to test which hardware is broken so I had to get a shop to do it for me. Wanting to avoid the massive pain in the arse (I couldn't play any games for 3 weeks and 2 of those weeks were over the school holidays) and wallet again, I do not want to blow up another psu. What temperatures are acceptable for my psu and what can I do to cool it down. My case is pretty small and I have an intake fan on the front panel and space for a fan on the back panel. Also by "rated for 50c" does that mean max ambient temp of 50 or psu temp of 50
My specs
CPU: i5 7500 (stock cooler) @ 3.4 ghz
GPU: ASUS STRIX R9 380 @ 990 mhz
RAM: 8gb 2133 mhz
PSU: EVGA Supernova 750 B2 (rated for 50c)

Your psu is excellent, tier 2 on this list:

750w is more than enough for your parts.

The 50c. spec says that the psu can deliver advertised power even at 50c. temperature in the case.
A cheap psu may only deliver advertised power at room temperature which is unlikely in a case.

What is the make/model of your case?
It sounds to me like a single front intake fan is not sufficient to take in sufficient cooling air for your graphics card.
The I5-7500 is very efficient and will not enter into the heat equation at all.

If you only have a single front intake position, your best option is to replace the intake fan with one of higher
capacity. You can buy extremely high rpm...

Whatever air that comes in will exit somewhere. Rear exhaust is not really necessary.
My suggestion would be to relocate the front fan as an exhaust and install something stronger in front.

Unless you are in love with the case, perhaps you should look into a better cooling case.

I would not worry much about the psu temperatures, the psu fan's job is to keep the psu temperatures in the safe zone.
Normally, I would not expect the fan to run so fast that it is audible.
