Hi

If your PSU is the XQ 500W then it'll be fine, if its the R3 then You'll have to have a look at the label on the PSU for us and look for the wattage under the +12V rails(s).

Yeah its an R3, the specs list the +12V rails amperage but not wattage which is really important to know.

You can use a molex to 6 pin adapter like this:



Like I said before you can check the +12V wattage on the label of the PSU.

Wow, that's annoying, I expect it would be fine, but I would personally contact Xilence to find out the wattage dedicated to the +12V rails. Just to be on the safe side.

The higher the quality of PSU the more wattage will be available to the +12V rail(s), In your case I would say you'll want atleast 400W available for the +12V rails.
