I'm not so sure if 750w will be enough. I'm pretty new to all this computer stuff. Here is what I have:

Intel Core i5-4670K 3.4GHz Quad-Core Processor

Noctua NH-D14 65.0 CFM CPU Cooler

MSI Z87-G45 Gaming ATX LGA1150 Motherboard

Corsair Vengeance 16GB (2 x 8GB) DDR3-1600 Memory

Seagate Barracuda 1TB 3.5" 7200RPM Internal Hard Drive

PowerColor Radeon R9 290 4GB TurboDuo Video Card (is this a good video card I haven't seen reviews on this)


NZXT Phantom 410 (Red) ATX Mid Tower Case

XFX ProSeries 750W 80+ Gold Certified Fully-Modular ATX Power Supply

Asus DRW-24B1ST/BLK/B/AS DVD/CD Writer

Microsoft Windows 8.1 (OEM) (64-bit) (not sure if this affects anything but just put it just in case. Sorry I know it may seem common sense but I'm not sure)

Feedback would be great ,thank you! :)
 


I think that 550W is a little bit to small, Seasonic S12II 620W or XFX Core Edition PRO/ProSeries 650W is minimum.
 
I won't be doing crossfire and all that stuff yet I might do that later on , just have there just in case. Also if it's an over would that much wattage damage the system I rather just have it at 750 since it seems high and also since I'm already here do you guys no any type of antivirus that I should use ?
 


You will not damage your system by having a more powerful PSU than required. Windows security essentials is a decent light weight antivirus, or you can try AVG, komodo, etc... a quick google search will list off the top free antivirus that are out there.

If you plan on going crossfire you may want to grab an 850W PSU because the r9 290 can use up a lot of power at peak consumption.
 
Alright thank you I understand now and I have another question for those who don't mind,sorry, what's the difference between a windows 8 oem vs the full version?
 


After you get 5 or so solutions they let you pick or un-pick best solution (except on yourself), confused me at first too.

I also agree that the xfx 650w would be a good choice.
 


Windows OEM license are "usually meant to stay with one computer,so if for instance your motherboard dies (what happened to me) or you sell your pc and keep the OS you will have to call Microsoft and ask them to transfer it over.

Non-OEM OS's you just don't have to go through the hassle of asking permission of Microsoft to reuse your OS.
