no, because it doesn't quite work like you think....each phase would do the powering out of step with each other, they don't all switch at the same time. in each cycle, each phase is taking a turn a 3rd of the time. so your PWM is really...

well The FETs are your main drivers (should be two per phase) and then the choke (one per phase) and then smoothing caps after the chokes. now the FETs that hook up to the phase next to U503 (on the other side of the board) I think were...

Damn! the chokes are on the other side of the board by the looks of it, as are the main drivers. The back side there, only has the PWM controller (U501), and the FET driver chips for each phase (U503, U504, U505). C565 C566 C567 may be...

They ARE in parallel - remember we worked out it was only one dead phase (I think it was the top one?) Put the two chokes back on, and take off the other one, and see if it fires up. PS Can you put up a better pic of the VRM, so i can...

well, even at 12V, the current draw is 1.62A (I took the rating of the high performance fans - it will be less for the quiet ones ) As you have the 7V resistor in place, it will draw even less, as you are adding resistance into the...

Have you asked him what his CPU temps are? A thought that has crossed my mind - is it possible his chip is throttling, and maybe running cooler with the change in VRM frequency? I'm wondering if the different VRM frequency is making his...

I managed to change the controls to "tilt" which worked not too bad. And I swear it runs better on my phone, than it ever did on my PC. Awesome fun!

Yeah, well I was running off the recommended list - and both those sites had loads NOT on the list! I don't think the first site had a decent PSU under 100€. The funtech site seemed better, with a few under 100€. BTW, I noticed a...

I'm thinking one of these may do you - http://www.funtech.si/si/vsi-oddelki/komp/napajalniki/22496/ http://www.funtech.si/si/vsi-oddelki/komp/napajalniki/22478/ http://www.funtech.si/si/vsi-oddelki/komp/napajalniki/23690/ What do you...
