do i have enough wattage?

[markirox]

I am building a new gaming pc and i was wondering if i have a strong enough psu.

Parts:

Corsair GS-700 V2 Power Supply

Gigabyte GA-Z87X-D3H Motherboard

Sapphire Radeon HD7970 3GB OC Vapor-X Edition

Intel Core i5 4670K (i plan to overclock to about 4.0)

I have a 128gb ssd, 1 tb 7200rpm hdd

2x4gb ddr3 ram

The case has 3 fans in it and i have a seperate cpu fan (NZXT Havik 140 CPU Cooler)

I need a keyboard and mouse that use power from the usb port

and also a dvdrw

700W is easily enough for this system. You could run this system on 600W. Even with overclocking and extra components you'll never come close to worrying about power unless you add a second 7970. So, with one 7970 and 4670k overclocked you'll easily run this.

By the way, if you have a decent cooler (not Intel cpu cooler) then you should be able to get an overclock around 4.4GHz safely.

so do you think i should go down to 600 or 650w and get a better quality psu?

SeaSonic M12II 620 Bronze : semi-modular and enough power for your system. Also, no better PSU manufacturer than SeaSonic.
