PC fell down + one PSU question

So just like 15 minutes ago, my PC fell down. When I say fell, I mean the system unit struck the floor at a height of like meter (guesstimating the height of the table). It fell down because I was relocating my desk, the system unit is placed on another table (If you're asking why, I'm on a flood prone area so I can't place my unit on the floor; the table was the only thing to put it on to.) while the other things are on the desk. So I moved the desk closer to the unit then rotated it at 90° clockwise and pulled the desk to the right. I was struggling to pull the desk because one of the wheels is jammed. So I was looking at that jammed wheel when I was pulling it and then I heard like a bang. Checking the other side, I saw the unit is on the floor. I knew that my PC was fine because I was playing a song and it was still playing after it fell. The first thing that came in my mind is "Is the HDD fine?" and my answer is yes; and according to the spec sheets, my drive can survive a 30G~65G fall when it's working and I checked it with HD Tune with no problems. Plus the position of the HDD is upright so it's parallel to the direction of the fall (Does this help? Just for future reference).

Now the question is there any part that may be damaged? For now, all is fine.

When my PC fell down, I was actually surprised that everything survived considering that most of the parts are like 3.5 years old (GPU is almost 2 while HDD is 10 months). It gave me a mini-heart attack when it happened. Now I'm the one to blame for it because I overlooked the cable lengths and I was negligent for not looking at the unit.

The GT 610 recommends a 300W PSU however I only have 250W; there are some posts that say if your PC is under-powered, your hardware can fail. The GPU is here for almost 2 years (bought it on Christmas, 2012) on my PC yet I don't have any problems. Is there a risk for me (I'll be upgrading this PC soon)? The other question is: Am I not getting the most of my PC since it is under-powered?

Personally I'd recommend opening the unit up and check that everything looks fine (no visible damage), all connections are properly seated and all cables and connections are firmly made.

Checked it thoroughly, no damage at all. The only cable that was loose is the monitor's power brick, apart from that, everything works.

Just monitor your temperatures for a few days. I'd be tempted to run MemTest86+ too.

Will do those. Currently, temps for the following are (max value): MoBo = 31°C, CPU #0 = 56°C, CPU #1 = 49°C, HDD = 36°C and GPU = 47°C. Those are the temps when I'm just browsing the web (which is what I'm doing now).

Now the question is there any part that may be damaged? For now, all is fine.

Things that might get jarred loose would be the Ram and Video card.

I am actually more concerned with the cured bond of the TIM (thermal interface materials) between the CPU and its heatsink since that is a large, heavy chunk of metal hanging off the motherboard. A hard "bounce" can not only break the cured bond (allowing unwanted and insulating air between the mating surfaces) but can put undue stress on the motherboard near the socket and heatsink mounts, and where the motherboard mounts to the case. This is why heatsinks - especially big aftermarket heatsinks - really should be removed during transport.

So if me, I would unplug from the wall, touch bare metal of the case interior to discharge any static in my body, then carefully remove the heatsink, clean the mating surfaces of old TIM (I use 93% isopropyl alcohol), then properly apply a fresh new layer of TIM. And remember, the purpose of TIM is to ensure ONLY and all the microscopic pits and valleys in the CPU die and heatsink mating surfaces are void of heat trapping air, maximizing surface to surface contact. Any excess is too much and gets in the way, and can actually be counterproductive to the heat transfer process. So start with a very small amount, about the size of a grain of rice, and spread it as thinly as possible across the CPU die.

Those CPU temps are too high for just web browsing.

In spite of what I just said about the heat sink and TIM, I disagree those temps are too high. 56°C is warm, but not hot - ESPECIALLY considering the ambient temperatures in Manila, Philippines, and the fact we don't know what the temps were before the drop.

Did the memory test and found no problems; also, no parts were loose. Here's the temps, did browse the web, watched videos in YT and a did a quick scan in MSE. The space for the system unit is very large and not obstructed.

Edit: I was also able to play games in the past few days (BF2:PR, DEFCON, CoD: BO2) and found no problems. The temps on those days (AFAIK) are: CPU's reaching 65°C, GPU at around 67°C, HDD at 36°C and MoBo at 30°C.

Edit 2: Also, I've always noticed that TMPIN2 has a buggy temp readings. It's been like that for the past 2 years.
