Need Help With PSU Choice

Solution
All I can say is you'll have to try it. A local PC shop can flash it for you and it shouldn't cost much. Better yet, find a friend with a compatible processor and get him to let you borrow it.
Your GPU recommends 450 watts with 17 amps on the 12v rail, minimum. A 550 watt or larger is what your looking for. Hard to beat the quality of this Seasonic for the price:

Evga has a 550 watt, a little more expensive, but also very good.

Oh my cousin told me that I should get a 750w. While I don't want to fry my parts by getting too little power, I also dont want to pay for what I don't need. Are you sure 550w won't be too little considering its an AMD build?

Best 550w on the market plenty of power.

Great price on the best 550w.

550W G2 review.

Performance (40% of the final score) - you probably already know what I'm going to say here. Voltage regulation was excellent, averaging 0.9% in the hot box. No points deducted. Efficiency was a pass for Gold both times. No deduction. Ripple control was amazing, and probably the best I've ever seen, so definitely no deduction there. I saw no issues with anything else, so this unit gets a 10 here.

Functionality (20% of the final score) - this unit gets everything right. Even the CPU cable, which I thought was terrible on the 650W, is done right here today. Semi fanless mode works well, the manual is decent, we got lots of connectors to power anything a 550W unit should power, and the box came with more goodies than I tend to expect with such a small unit. 10.

Value (20% of the final score) - you can get one of these for $84.99 at Newegg right now. That's a fair bit for a unit this size these days, but as always EVGA is right at the bottom of the cost pile when it comes to 80 Plus Gold and full modularity. The nearest competition is their own 550W GS unit at one dollar more money. This is nuts. How are you making any money on these, EVGA? 10.

Build Quality (20% of the final score) - oh, snap... EVGA just got another perfect total score. There's nothing wrong with this unit. Nothing. 10.

If anyone can still help me out, pcpartpicker says my gpu is too long for my case. Any cases that are good around the same price as the nzxt source 210 that can fit a 258mm graphics card? In the compatibility notes, it says it might block drive bays. Not sure if this means it'll fit without a harddrive in that bay.
 

Thanks I'll probably go with that motherboard but I'll stick with the EVGA PSU.

 

Thanks, one last thing. Compatiblility notes also say "Some AMD 970 chipset motherboards may need a BIOS update prior to using Vishera CPUs." Do you know what to do about this?
 

Do I need the latest bios? I dont have another processor...
