Last night I went to the Micro Center and bought a new MoBo ASRock Z97X Killer and a new processor i7-4770K. So it was an upgrade from my ASRock Z77 Extreme 4 and i5-2500k. But now I have an issue. I don't think my PSU (Antec 750W) is enough for what I have in my computer right now. This is what I'm running as of today http://pcpartpicker.com/user/sebat4/saved/hKbwrH . My Video Cards are actually MSI N670 PE 2GD5/OC. The case comes with 5 fans 2x 200mm LED and 3x 120mm. There are some other things connected to my USB (5 things: Laser Color Printer, G12, G600, Razer Lycosa, G930 headset) and every time I connect G13 to my USB port computer will run but when I turn it off it won't start until I disconnect my G13 gamepad. I'm just wondering if my PSU is enough for all this or do I have to get a bigger PSU ? Any help would be great, thank you in advance.
