I'm searching for an ATX power supply which is powered by a 12V input. Peak power 300W.
- 1 standard ATX mainboard connector
- 1 4-pin cpu power connector
- 1 6-pin PCI-E power connector
- 2 SATA power connectors (5V is enough)
I found various power supplies which provide only the first two connectors. Now I can improvise the SATA connectors (step-down the 12V to 5V, wire up the connectors, done), but the PCI-E connector isn't that simple I think (has a sense line to compensate for voltage drops).
A sufficient answer would either be the power supply I described, or if someone knew if it's possible to drop the sense line from the PCI-E connector (and if the answer is yes), then that would also solve my problem.
