Is it possible that the psu could run a 560...yes. Would I do it...no.
LINK
Link has 560 normally not pulling more than 160w, but a maximum of 220w recorded
SALE FOR PSU. Memory express only until the 3rd (monday). Not the best of the best PSU, but definetly going to be more than enough for what you need and at a price that won't break the bank. Corsair builder series 600w for $35. Don't think too many people would argue with bang for buck on the psu at that price point.
