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.

two 670's would be 330w and your CPU would be 84w. Since you are over clocking, a 650w-750w is recommended.

Your PSU should be alright, depending on how old it is. If you wanted to get a new one

Comes with a 7 year warranty.

A 650w would work to, but a 750w would work for many other higher level cards and is only slightly more. I am just thinking in terms of you using it in another build someday :)

Well then I guess I'm set for now, but what makes me wonder is why when I connect my G13 Logitech to my computer it doesn't start. I can press and press the power button and nothing happens, but as soon as I disconnect my G13 it will start w/o any issue. At first I thought it was my PSU problem and there wasn't enough power but now it seems that I have a fair amount of watts left. Anyone has any suggestion to this problem ?

I've had my G13 for a while now (a year I would say) and its been weird even with my last mobo (ASRock Z77 Extreme 4) mostly I had blue screen crashes but sometimes my USB made my keyboard unresponsive and as soon as I unplugged my keyboard I had crash. Plugging in my G13 to a different USB port didnt help either, still same thing happens.
