Upgrading a prebuilt with a more powerful gpu(rx580). The 440w psu in it is most likely not enough so I'm trying to decide what I need.

Specs are:
Processor: AMD FX 8350 8 Core, 8x 4.2 GHz (4.00 GHz base clock speed, 4.2GHz with the AMD Boost Technology)

Motherboard: Gigabyte GA-78LMT-USB3 AM3+ (1 x PCIe x16, 1 x PCIe x1, 1 x PCI, 4 x SATA 3Gb/s, 2 x PS/2 keyboard/mouse, 1xDVI, 1xD-Sub, 1x VGA, 1 x GBIT-LAN, 4xUSB 2.0, 3x Audio jack

RAM: 16GB DDR3 PC-1600 (Dual Channel)

SSD: 256 GB SATA III

Hard drive: 1TB SATA III HDD

I just cped that info onto there, let me know if you need anything more specific! I'm leaning towards a 600, though I've seen suggestions for higher I'm pressed for cash.
