The Ultra X Connect has insufficient PCIe power connectors for a GTX 560ti 448 Core and is of questionable quality. With the advertised 34A on the 12V rail it meets the minimum electrical capacity that I would recommend; but I always recommend using a PSU that has the required PCIe power connectors and avoiding molex adapters. I recommend upgrading to a good quality 500-550W PSU with 36A or more on the 12V and two 75W 6-pin PCIe power connectors. The Antec Neo Eco is a good PSU at a great price of $50 right now: http://www.newegg.com/Product/Product.aspx?Item=N82E16817371030&Tpk=neo%20Eco%20520
It's made by Seasonic and is based on their outstanding S12II-520 PSU. For $10 more I'd go with the Seasonic S12II-520 itself: http://www.newegg.com/Product/Product.aspx?Item=N82E16817151094&Tpk=s12ii%20520
for two more years of warranty.
