If you are not breaking anything, you are not going fast enough.
Well, I guess that I'm AOK then!
I've killed two supposed quality power supplies, a F5900 XT vid card, 4 sticks of RAM, 1 CPU and 2 motherboards.
In all cases, I trace it directly back to something that I personally did.
The video card gave up it's life after a cross flash gone good with a self modded BIOS. It went so good that after just twenty minutes of playing UT2003 with much better FPS, smoke came off of the card and that was that!
The PSU's died from just sheer abuse. back when everyone thought that a PSU was a PSU, I ran 4 80mm Delta High speed fans, 4 HDD, another modded vidd card (cross flashed and modded 5950), A Barton CPU at 2.0 volts, 1 GB RAM at almost 3.0 volts for gaming. The sound was amazing (I needed a headset to not go deaf).
The PSU's (each time) let go and took out the vid card, the motherboard and one of the HDD. Don't believe that any PSU will do............headroom is your friend with ragged edge voltage loads all over the map.
The RAM diead of abuse attributed to overvolting/overheating beyond reasonability.
