Lol My sig rig would have been fine on a 450W PSU, but i saw that ultra LSP 750W on the shelf right next to the OCZ Fatal1ty 500W (which was on sale).... and i was like.... zomg! soo cheap!!!! i take it home, slap it in, and it starts running a little loud, for around 60% load... so i did some research.... and go figure, its a rebadged POS >.<<br />
Im not even kidding, when i shut down my rear case fan, my 2 front fans, my top 140mm, and my Graphics card fan to 20%, i can hear it over a single CM R4, this makes me want to just pick up the PSU and throw it out the window..... but hey, ill make use of that 40 bucks while its still working.
Thanks for making this Phaedrus, hopefully it will prevent some of the many overestimates of power requirements recommended to people in threads on this site!
I'd go as far as saying that the majority of users on here have too much power for what they are running, and all too often I see these same mistaken users recommending far to powerful PSUs to people. I'll just link to this thread in the future! Long overdue a rough guide like this is I think...
