I'm wondering whether or not my PSU might be too weak for my current system, I have been having crashes in some high end games (although not all of them), even though the games run smoothly with no indication of the computer not being able to handle it. These crashes started happening after I upgraded my Graphics Card, which, as rated, now might use as much as 80 watts more power than my previous card could use on full load. Old one full load: 100watts, new one (as listed below) full load: 180watts.
Here is my current specs:
500w Gigabyte PSU (now about 3 years old by the way)
Intel Core 2 Quad 2.40GHz (Q6600)
ASUS Motherboard (P5K-VM)
500 GB Seagate HD
2 TB Samsung HD
4x DDR2 1GB 1066
Radeon HD 5870 1GB
3 80mm case fans
At first I thought a component (like maybe the CPU or GPU) could be overheating (since it is now summer here in South Africa), thus I added more case fans to get a better air flow, I have checked my CPU idles at about 50°C and my GPU at 42°C, so that's now normal if you ask me (the 3 fans I listed above includes what I have newly installed), so I went back to play a game which normally crashes quite early on (the computer would stop responding followed by graphical lines across the screen in which case I can only restart the PC at this point) and have yet to experience this crash, however, this is inconclusive as I have not had the chance to play for a long session to really test if these extra fans had fixed this problem and that the problem was indeed caused by heating. (I have even updated my Motherboard and GPU bios's (and drivers where needed) just in case)
I have calculated the watts necessary based on my current specs and get results differing from site to site suggesting I need 400watts recommended to another saying I need 550watts recommended. What would your opinions be on this? And what are the symptoms of a PC being underpowered, as I get different feedback from this question based on whom I ask, so any advice and suggestions here would be very helpful! Thanks!
