500w enough for 1080ti and 4790?

Solution
System Power Supply Requirements for a single GeForce GTX 1080 Ti
NVIDIA specifies a minimum of a 600 Watt or greater system power supply. (Minimum system power requirement based on a PC configured with an Intel Core i7 3.2GHz 130 Watt TDP processor.)
the system power supply must also have a maximum combined +12 Volt continuous current rating of 37 Amps or greater
the system power supply should also have at least one 75-Watt 6-pin and one 150-Watt 8-pin PCI Express supplementary power connectors. There are some non-reference design cards that require two 150-Watt 8-pin PCI Express supplementary power...

It's an FSP low-end PSU. I guess it Isn't enough so, I'll get a decent corsair 600w.
