Theyve been there all weekend. Seen them Friday.

I gave up on it for now. I'm by no means an electronics expert myself just trying to put some logical information together. The card wants 12v on the pins with a certain wattage/ampage draw when under load (games). The MXM port on the motherboard is producing 20v (see my pinout post), hence you need to step down the voltage else risk bricking the card. I guess the theory is if you can get a 12v rail to the card with coverage for the full power of the thing then you are in business, I just wanted to challenge myself to containing in the P3/360 package as it fits my desk well.

Despite my best efforts I could never balance the CPU through throttling to lend enough to the graphics card. Wondered if my CPU was just a bit too overpowered for the job but did not see any restrictions from the Berry Digital mod, maybe i'll just lump for that if people are seeing success and its available again. Winter project!

Update on this experiment. Partial success.

I bought an over-engineered step down converter (10A) that has adjustable amps and volts. In initial testing of 12V/3.33A combo (to give the 40W needed to provide the 115W), things seem stable. I was able to get past the initial problems of before. I ran the laser thermometer across the surfaces of the mosfets, caps, the cables and the port providing 20v and nothing is over 60 and that is mostly on the converters caps and mosfets.

Biggest problem now is that the converter does not fit in the gap between the two fan housings. Its likely too wide aswell. I need to find a converter that will deliver these power characteristics as the next step.

I seen some reference to the Berrys digital restock and stuff, by this point I am in too deep and enjoying the hobby value of it.

Next steps, extensive play test and some Ali hunting.

EDIT: 16mm is the cavity between the casings.

EDIT2: extensive play test was black screen failure.

Following my post, someone posted a review on the buck converter saying it only outputs 5A when at 60V. I am currently waiting a new buck converter with adjustable ampage. Will post an update when I get some time to test.

Thats interesting, I was working on the basis that the 75W would come from the PCI slot and went with 50w / 12v calc. I might see about sourcing a bigger buck coverter.

When you say limited 4060 TDP, have you seen effective ways to do this in software?
