I got a name branded cheapo one with no specs! Didn't realise it had that much power! The 2 rail thing is handy to know instead of loading one to death! Thanks for all the help! |

For grins, here's the ratings from an old 490W supply out of a Compaq server from the late 90s: 3.4V 18A 12V 12A 5V 75A You could weld with this thing! Due to the way power in computers works these days (CPU/GPU cores, which consume the most power of everything on the system, use locally generated supplies), a lot of the power has migrated to the 12V rails, but 400W is a LOT of power. Now, do be aware that, if you have a cheap supply, it's probably not actually good to the claimed ratings for any period of time. I'd derate it by at least 25%. This means your 400W supply is more like a 300W supply. Oh boo hoo, it's still got more juice than you'll ever need just for some LEDs and fans and such. |
