i'd like to use electrodacus' 130w winmate psu to power my computer. here are the parts:

- gigabyte h55n-usb3 motherboard
- intel i3 530 cpu
- 2x4gb generic ddr3 ram
- radeon 5750 passive
- corsair 128gb ssd
- generic sata dvd burner

in terms of wiring, the plan was to get a 1-in-2-out sata power splitter (here) and a 2-molex-in / 1-pcie-6-pin-out adapter (here). the psu's 20-pin and 4-pin aux would go to the motherboard, the 2 molexes (one on the psu, one split off the 20-pin cable) would power the 5750 via the 6-pin adapter, and the sata power from the 20-pin cable would be split between the dvd burner and ssd.

does this sound like an awful idea to anyone? i think a fully loaded i3 530 + radeon 5750 will push 100 watts, but i really want to make this happen. the antec neo he 550w i'm running now has a horrific coil screech when drawing less than 70 watts or so, i want to be rid of it.

electrodacus has an add on part that allows you to hook up two of the PSUs in tandem. You should use that just to make sure you have enough lower to power all that.
