Is 650w enough for this build?

Can this Power Supply handle it?

Yes 650W is enough for that build.

That's plenty, and thats an 80 PLUS GOLD PSU great quality PSU so it will cope easily

For stock: 650W is enough.

But I wouldn't plan on much overclocking on that i5 and/or the 770 with 650W.

I think they would need quite a bit of overclocking(the kind that would kill the cpu and video card) to push past what the power supply will put out.

Also 80+ levels have nothing to do with the power supplies ability to cope or even the quality. It is an efficiency standard. Now you need higher quality parts to get this level of efficiency, but this does not mean you can not get as good or better power out of a different design. 80+ should always be thought of as a way to get a more power friendly system and in most cases a more quiet system due to lower heat generation.

OP has TDP's of the CPU (84W) and GPU (440W) listed in the first post, if allowing for 50W for everything else in the system - Stock TDP is around 575W at full CPU and GPU load.

A 75W increase in draw wouldn't take much overvolting of the CPU/GPU and that puts the PSU to 100% load. Rule of thumb I've always used is max draw of ~80% capacity of the PSU in order to keep it quieter/temps down. Also efficiency drops as a PSU gets close to its maximum output.

I would like to know how you come to the conclusion that the video card needs 440 watts.

The card it self only has power plus for 300 watts and the gpu it self has a power limit built in. The card has a TDP of 230 watts enforced by the drivers. It is NOT a 440 watt card.

Please post your links to this card taking 440 watts.

GIGABYTE Announces WINDFORCE 3X 2-SLOT 450W Cooling System with GTX 780 Overclock Edition This will list the 450 watt capacity of the cooler not the heat the card makes.

If I put a 300 watt dissipating cooler on my i3 does it take 300 watts now?

GIGABYTE GTX 770 WindForce 3X OC 4 GB @ techpowerup.com Note the TDP

Gigabyte GeForce GTX 770 WindForce 3X I know this is the 2 gigabyte card, but 2 extra gigabytes of memory does not take 200 watts. Also note these are at the wall wattage so the power supply is providing less due to the loss of conversion.

Not trying to show you up or put you down. I just see too much information and the big one is users claiming that video cards need insane levels of power. That is followed closely by the claim that 80 plus power supply deliver more power at the same rated wattage(rated wattage is rated wattage) They TAKE less wattage to make the same amount, but that is not the question. an 80+ 300 watt power supply with the same ratings as a non 80+ unit will both put out the same power to the computer
