If i'm not wrong each card needs 2 (6PIN PCI-E) connectors but that psu has only 2 of those connectors , this mean that you can't have 2 GPUs.
You can always try and use molex-to-pci-e connectors but thats always risky as its not really clear which rail the power comes from and it goes against the designed usage. It works in some cases and not in others.
To be safe its a good idea to keep the number of pci-e connectors in mind when choosing a PSU.
