How do i wire up the power source on dell sx 280

limited information generic answer --find engine and under plastic is plugs and wires --if you have a diesel then get an owners manual and read up on vehicle because their are none

220v 1 phase wiring is a EU standard.

THAT QUESTION YOU SHOULD ASK A GAMER'S FORUM.

There is no S280 in the Optipex model line, just GX 280 and SX 280.
The problem you are describing is common to the GX 280 model.
Here is a link to the manual:
ftp://ftp.dell.com/Manuals/all-products/esuprt_desktop/esuprt_optiplex_desktop/optiplex-gx280_user%27s%20guide_en-us.pdf
Select "Small Form-Factor Computer" and then select "About Your Computer". Scroll down to "System Board Components".
To the right of the processor is a smaller heat-sink attached to the motherboard via a wire similar to the size of a paper clip bent open. That wire is soldered to the motherboard which may have loosened it's connection and the circuit is open. This heat-sink on the chipset of the motherboard. The wire needs to be re-soldered to the motherboard.

Well that depends. What do you want it to do after you rewire it? Are you wanting to install new pickups or add any features? One of the best sources I have found for wiring diagrams is Seymour Duncan. They not only have listings for how to wire their pickups, but also many of the common wiring diagrams for many guitars. Please only do this if you feel comfortable with soldering. Otherwaise, take it to a local luthier.

if the power LED is a solid amber color, the motherboard on device attached to the board has failed. Disconnect all external connections except power, remove any expansion cards, power system on see if any change, if change add items back one at a time, if no change replace motherboard
If power LED is flashing amber, replace the power supply

Power source harmonics. Or its power supply regulation. Check also if input line is touching something.

Try a different stick of ram if avalible and open the case If i remember there should be 4 lights in there and If i remember that mean memory not reconized or being properly used

brand and model of the computer would be good.... as well there is a switch on the back of the computer on the power supply. toggle it to the other position and try again

Simply stick the tip of a screwdriver in the input and it will reset. (:
