Hi everyone. Soon I will be moving to London and I am building a gaming pc. I have a budget of £3000 and will spend it to build my pc.
This is my build:

How much wattage do i need for this bulding? I will mostly play Dota 2 and all the other famous games really.(Overwatch, BF, CoD etc.)

You guys are experts that's why I came to ask for your help; what would you suggest me to downgrade from that build? Because I feel like I might have to change some of those parts for example the motherboard or is the memory too much?

Oh and one last important question: My storage, I am planning to use only SSDs I'll buy Samsung 512gb pro for my OS and Dota 2. The other however I haven't decided yet. I'm thinking of something like 1tb 850 evo? I am not going to use a lot of space really other than gaming. :)

Best regards,

  1. For gaming only, 16 GB is plenty. The GPU draws 250W at peak; therefore a quality 500W PSU meets the requirements. Unless you need more storage, a single 1TB SSD would be fine.
  2. I would suggest something like this along with the soon to be released 8700k on a z370 mobo like the Asus Strix or asrock fatality or msi gaming pro carbon :

  3. Thanks for the answers. I've changed the 512gb ssd to 1tb.
    I wonder what will happen if I buy more wattage than I need? What if I buy a 850 wattage? Or 1000? Would it have any bad effects on my pc?

    Also I am going to buy a laptop for my university therefore I will need to install an office microsoft student on my laptop for my essays and stuff. Do I really have to buy 2 of them to use both on my laptop and desktop?
    Any help will be appreciated. :) Thanks

    No issues with going for higher wattage. The issue is quality. Make sure it's a good one.
    Windows license usually is single user. So yes you need 2.
  5. Thank you @Lucky_SLS.
