The Studio XPS 435T/9000 supports a standard ATX power supply, with an 24-pin, or 20+4-pin [PWR2] main motherboard and a [PWR1] EPS/ATX12V 8-pin, power connectors.
A power supply with five SATA power connectors, is needed.
You should be able to buy a compatible power supply from either a local or online computer store.
