450 watts sfx psu from silverstone

is it enough for max load of gtx 780 ti and i7 4771

 

[Illumynization]

no, with you average mobo, heatsink, case fans, ram, hdd, you will pull about ~440W. While it is rated to give you enough and can do so most of us would highly suggest stepping up a bit to be safe. Trying to save money on a PSU is risky since it can mess up everything else if it does not deliever.

You'll need a 750 watt psu minimum, preferably 850 seasonic

 

[Shocking777]

Nope a 600 watt by seasonic/XFX would be enough. Silverstone would be good also

what a shame, but i like this case so much http://www.newegg.com/Product/Product.aspx?Item=N82E16811163252
tell me which one can fits it?

 

[davcon]

I think I see what kind of build you're planning.
I can't give you a definitive answer though.
I have seen some Steam boxes with those types of components.

I'm liking your build more!

750W is overkill.

Depending on the rest of his components a Seasonic 620W would probably be his best bet. if he is trying to save some money and he doesnt have components that draw a lot of power then he might be able to go to an XFX 550W. You will need to check your power usage with a wattage calculator.

How much power do you need? PSU wattage calculator

I recommend you get a Seasonic 620W

As far as I've seen so far,i think that particular psu was used in similar configs.
The best psu available to my knowledge for that purpose atm.
I think you'll see more power options from other makers in the coming months.

After careful consideration, you can use that 450W PSU in that case with a 780ti as long as you choose your other components very carefully. Pick a board that will not draw too much extra power for features you don't need to have.

I don't know your budget, but I suggest looking into a build along these lines.

With that board you are still looking at 393 W. The 450 W gives you just over 50W wiggle room and its 80+ Gold rated meaning you get and Efficiency rating of 87%~90%.

I'm just not sure how long you will be waiting for.

some months just for a small stable console killer

got a similar setup on the rvz01 just built last week:
i7 4790 (non k) w/noctua NH-L12
evga gtx 780ti sc acx
16gb ram
asus z97I plus
no OD (still debating on adding one)
450W SFX 80+ gold

tried out BL2 yesterday and going to install BF4 on there later this week.

Silverstone has a 600W SFX psu (80+ gold) debuting this month.

The noctua cooler has small compatibility issues with the case/motherboard setup. You can only use the 90 mm bottom fan, which IMO is not a huge issue because you can mount a low profile fan such as the scythe slipstream on the cpu vent. The orientation of the cooler can only go one way with the heatpipes parallel to the I/O backplate and touching the rear vrm heatsink and PCIe riser, in which a piece of cardboard was wedged.

All in all, the setup runs like butter, its cool and quiet and it really shows that powerful systems can be built into SFF.
