Ever tried actually getting out of a computer supply what it says on the side? good luck! these things suck! I had one I was trieng to run my 17 watt diode with and it said on the side "5v at 35 amps!" YA RIGHT! It couldnt do 9 amps without smoking! LOL! ;D
I dont know how they come up with the ratings on these things, but they arent even close to what they can actually do. It would be very cool to make dry ice though!
hmm, well, I have tried 3 diff ones to run that diode, all three maxed out at 9 amps! one actually ran for 4 sec before smoke came out the fan vents! ;D ;D The rating must be for instantaneous surge or something, eather way, I never got close to the 27 amps I needed.
I was trieng to achieve 27 amps at less than 2v. I decided to start with trieng for 8.9 amps since I had a nice big resistor!10watt .56 ohms. the psu was labeled as bieng able to deliver 35 amps, at 5v and smoked at 8.9 amps! the psu was labled as 450 watt! lol! not EVEN able to deliver 9 amps?! ;D ;D ;D I had a .56 ohm resistor in the 5v line, I used all the +5v wires togather, checked them with vmm, so as not to strain one output. as soon as I swtched in the resistor, (4 sec on the last one) it started to overheat.
.56 ohms load,
5.0~ volts supply, 44.64286 watts!
8.92857 amps were expected from this... which it almost got to.
anyway, my point was that trieng to get whats labeled on these is imposible.
