Hi, I'm in the process of gathering parts for my first build, and one of the last stumbling blocks for me is finding an appropriate power supply. I don't know why, but this is what I'm having the most trouble understanding. Here's what I've got for my build so far and as far as I can tell, I just need to find a good PSU.

PCPartPicker part list:

That's the power supply I picked right now, but it's more of a place-holder. I can't really get a grasp of whether a certain PSU will be compatible all my parts and I don't understand how to pick one that will have enough power. I've seen posts here that mention 12V rails and amps, but it's really just flying over my head. I see similar builds where people are throwing in 750w PSUs and others with less. Also, I'm trying to set myself up so that OCing is a possibility in the future if that matters when choosing.

As a side note, if there's anything glaringly wrong with my current build, please mention it lol. I like the pieces I've chosen, but I could be overlooking something obvious. Peripherals and OS aren't included as they'll be paid for outside of my budget on PCPartPicker.

Look for a PSU around 500w, you shouldn't need more than that for your build. Stick with a Corsair (not the CX series), Seasonic, or XFX PSU.

Thanks guys. The Power Supply 101 link helped me get a better understanding, and I think I'll follow cin19's suggestion and go with the Antec PSU.
