I'll get right to the facts.
I have a pre-built computer with a 220W PSU, it runs games fairly well, but I got myself a smallish graphics card to help give it a boost in gaming. Long-story short, the graphics card drew too much power and crashed my board (I couldn't even turn the computer on until I performed a BIOS reset). I left the graphics cards aside for now, but about 3 or 4 weeks ago something similar seemed to happen. The computer shut down and wouldn't turn back on. I didn't have to pull a BIOS reset this time, I just yanked the optical drive out and it seemed to work. I worry that my PSU is dying though, so I've got a bit of urgency to replace it now.
I probably don't need much more than 300, but if I'm going to buy one... I figure I should get one that will last. I want to get myself something I might be able to put into a self-made rig one day, something big and beefy and modular, with 750 Watts. My worry is what will happen if I plug this thing into my little pre-build mobo that's used to using 220W. And even if the mobo can handle it, what happens to the extra 500 watts, do they dissipate as heat? Or does the PSU really only generate what is needed?
Also,
I performed a test by yanking the power wires connecting from my PSU to my motherboard (after I had shut it all down of course). I've never switched a PSU before and I wanted to see if I could get this right at least. I waited a few minutes, plugged it back in, and the computer turned back on again but something was weird with it... it acted similar to how it did when I pulled the BIOS reset. The clock reset to the factory settings (January 1st 2010), and every window I opened had a stuttering lag to it. Also the lower-right icons in the tool-bar all turned invisible. It wasn't serious, like last time it happened I just did another reboot and it went away. But I just worry if this is some kind of... sign, that messing with my computer's power supply is walking a fine line. Or if it's not at all normal and I have some serious problem with my mobo.
By the way, these are the two PSUs I'm hesitating between. I figure that... for 10$ more I should go for the 750W one. Both are fully modular too, why I want them.
