Hi guys, thanks for the suggestions. I think iirc my atx can supply on 8a @12v. I say can, I should say could...of course I've killed it now!! Those big server supplies look like a good choice, as do all the other recommendations made! Just gotta keep an eye on fleabay for something at the right price. Chris |

Tonybraz - does your motor ever stall with the 20a supply? |

Hi Chris, no I have not had the motor stall ,it has broken a couple of cutters when they become clogged. Tony |

Chris be careful with server power supplies. A lot of the leads and things are for measuring temp, drain etc. this makes them a bit more of a problem to get running. You also have the issue that some of them do a lot more than 12v so make sure you find specs first before purchase. You would be better off looking for a high powered PC supply instead, you can get these around the 1000w range. I have servers at work that use supplies that run at 60v to the MB. They also use a lot of -v lines too which is great if you want to tie lines together to get the voltage you want? they also share single negative rails on most modern supplies also. |
