Re: Heatbed Heater Options

Ah I think I've figured it out now. This is on the side of the ATX case:



So that means I'm going to need resistors across Ground and 1 x Red Wire (+5V), 1 x Orange Wire (+3.3V) and 1 x Purple Wire (5V StandBy), so that they reach minimum loads, am I correct?

If so, then by my calculations, these power resistors should do it:
27R @ 1W across the 3.3V (122mA)
47R @ 1W across the 5V (106mA)
47R @ 1W across the 5V (106mA)

1W resistors I should be able to get this week easily and cheaply, but before I do, I just thought I'd check to make sure that I'm correct in my calculations!
