Constant hardware crashes due to PSU malfunctions. I could use some help...

My personal computer is constantly crashing after a certain period of time and upon restarting throws me the Windows Alert popup saying "Windows has recovered from an unexpected shutdown".

It all started after a hardware change from an integrated Intel(R) HD Graphics 4400 GPU to NVIDIA GeForce GTX 550 Ti and from an integrated Power Supply to HKC USP-5550 in order to supply enough power for the said GPU. I'm pretty certain the issue isn't in voltage, rather than in GPU temperature. Reason being, I've taken some time to observe the surrounding circumstances right before the crashes occur and it seems to always happen when the GPU temperature reaches 65 degrees Celsius. To be exact, the last logged temperatures right before the crash peak at 64 degrees so I can only assume 65 is the upper limit right before the PC proceeds with immediate shutdown to protect the hardware. That, however, doesn't really make any sense to me, since based on the nvidia website, this particular GPU should have a temperature limit of 100. I've tried multiple methods of just keeping the temperature bellow 65 and it's worked so far and prevented any further crashes but even with regular hardware cleanups (blowing out dust and anything of a similar sort), it's becoming harder and harder to keep the temperature down. Are there any solutions to my problem? Should I invest into more cooling fans/other similar hardware or is there a way of increasing this "limit"?

I appreciate any kind of help and I hope this issue can get resolved somehow...

p.s. The GPU doesn't enter throttling mode, which should slow down the computer in order to drop the temperature, right before crashing. The PC just suddenly turns off without any warning and reboots.

p.p.s. Actually, the upper temperature limit seems to have "dropped?" to 62 now, whereas the moment it reaches 63 degrees, my PC proceeds to reboot. I'm not exactly sure how this is even possible since I haven't been tampering with these settings in any way (I don't even know how).

I guess the problem could really be in the PSU since I have no ways of monitoring its efficiency (not to mention I just noticed the crashes always happen at 65 C and took it as a given cause). Are you suggesting I invest into a new, more capable PSU or is there any sort of software that could resolve this issue?

I've obtained the PSU through some recommendation of a relative but I wouldn't really be surprised if that were the case. The GPU however functioned just fine on another computer whereas it could run more demanding applications and games on maximum settings with no loss or crashes whatsoever. I guess I'll take another look into the capabilities of my current PSU. (To be honest, it proved to be a little unreliable even with the previous integrated GPU but the crashes occured less often).

EDIT: The issue could be that the PSU itself is overheating and based on its specifications on this website it shouldn't surpass 50 C. Although there's no way to monitor its temperature so I can only guess. Can this thread be moved to a PSU-related section since I believe we've already concluded that the GPU doesn't seem to be the issue? Thanks in advance. While we're on topic, are there any recommendations for a more appropriate PSU for the NVIDIA GeForce GTX 550 Ti? (Note: my budget is pretty low so I'd prefer the price to stay in the 2-digit range).

Late update: I got myself a new PSU (Antec VPF550 550W) in hopes of this fixing the issue. Unfortunately enough, it did not. The crashes are still occurring on a regular basis. Could the problem be something completely different? (I'm 100% positive it's not a software issue). I'm running out of options here...

If it's of any help, here's the error I recieve after an automated PC reboot after every crash:
