One point that should be noted on this idea... as long as it cooperates, it |
8 |
should last pretty much forever, but your draw at the wall will likely be |
9 |
much, much, higher than it is now since the ~50-60W max you're drawing from |
10 |
it is so much lower than an older PSU is designed for (and efficiency drops |
11 |
the further from the load it's designed for you go, in either direction). |
12 |
The other issue I'm aware of is that a PC's PSU is designed with a minimum |
13 |
load, and they can have unstable/incorrect output if that load's not met. I |
14 |
would expect any PSU made in the past several years (where actual power |
15 |
draw of a basic desktop has dropped significantly) to be fine with the load |
16 |
you're throwing at it, but it's something to verify, especially if it's a |
17 |
meaningfully older PSU. Typically, the place you see that problem crop up |
18 |
is using a PSU for bench power, and running small embedded, very low power |
19 |
(i.e. Arduino and the like) hardware off of it. |

Whichever way you go, good luck! |
