Can pc parts ask too much of the Power supply unit, causing it to crash?

I had a thermaltake TR2 600 watts psu bought it on the same day I bought the XFX Radeon R7 260x 2gb so for about 4 to 5 months everthing was awesome then came the freezing, crashes but without the bsod the computer would quickly shut off and as if try to restart but could not get to the boot menu option.So after trying pretty much everything, software wise, I figured it was hardware
went thru the motions, used a program to explain what the event viewer error meant and said it was the gpu. Note that these crashes would be random, wether gaming or simply leaving pc idle. anyway, so i changed the psu to a corsair CX750M and gave it about 3 weeks until I decided it's fixed.good okay now I am thinking it was the thermaltake 600 watts so i check it out using a power supply tester, according to the tester everything checked out fine..I still have the R7 260x and no crashing, so my question, is it possible the gpu was asking for more power than the 500 watts or greater noted in the system requirements? or could I have missed something during my crisis? what do you think??
 


Hi - What more than likely happened is the TT was defective or as is the case with many low quality PSU's it
can't put out it's adv power specs. The TR2's are not a good series, and most trusted PSU reviewers have stopped testing them.

Your system could run fine on a good quality 500w PSU.
 


Hi again - You do not need to buy another PSU, your CX750M is fine for your system and has more power than you need, so you won't be taxing it. It is true that it's not a better quality unit, but it is not terrible either. It is
what it is and that's a budget level PSU and therefore uses cheaper internal parts(capacitors) than an enthusiast or professional level PSU would use.

However, there is no reason to believe it will do any harm (it has protection features) to your system, and could last several years. There are no trusted reviews that state this PSU is terrible or poor, etc.

 


You have to remember that those handheld "power supply testers" don't really put any load on the PSU. They simply turn the PSU on and check idle voltages.

The 600W should've been enough for your system, so as toyftw stated, obviously it was a bad PSU. The 750W you have now is more than enough.
