Yes, the card is 'compatible' with the motherboard.
It's compatible with any modern(ish) motherboard with an available PCIe x16 slot.
As for the PSU, that's another question alltogether. Without knowing a model number, it's an unknown quantity.
Unfortunately, just because a PSU shaped object has "600W" written on it, is no guarantee it can reliably do anywhere close to that.
If you cannot find a model number, can you take a picture of the PSU/label?
