Power consumption question

[SkulD]

Hi guys, i'm planing on moving my mITX pc to a Silverstone FT03B-MINI case and these are the parts that I am planing to put in there.

 

GTX 770 Graphics Card (230w)

 

Seagate Barracuda ST3000DM001 3TB 7200 RPM 64MB

 

GIGABYTE GA-Z77N-WIFI INTEL Z77 PCIe mITX

 

Intel Core i5-3570 Ivy Bridge 3.4GHz

 

Kingston HyperX Blu 8GB (2 x 4GB)DDR3 1600

 

Corsair SSD 60GB Sata3 Force Series GT

 

Thermaltake WaterCooling Water2.0 Performer

 

So my question is, will the power supply for this case, the Silverstone SFX Series 450W 12V 80PLUS Gold, will be up to the task of powering up this computer?, my main concern comes from the graphics card, since I know it will be the main power eater in the system.

 

I don't plan on overclocking, since I think i'm at the edge if not over what this power supply can deliver.

 

Any comment, thought, or help is appreciated. (^_^)

It will just not be sufficient Get atleast 650W.

[joelthezombie15]

500w will work but you would be safe at 650w

[Nit3Rid3R]

Yeah like what everyone else said, 500w would be enough to power it, 650w for the headroom.

gtx 770 -214 watts max

i5 3570 -77watts max

water 2.0 -27 watts max

SSD -3 watts max

HDD -10 watts max

water 2.0 fans -12 watts (for both)

1x140mm fan(.22A @12V,assuming the spec is the same as AP121) -3 watts

 

~346 watts max,assuming you don't have anything else.

this is not including any case fans other than the one included with the FT03 mini and the water 2.0 fans.

 

since the power supply is pretty damn good quality I'd say go for it you should be fine.

 

but I would highly discourage any overclocking.

It's fine, as mvitkun said you won't be going anywhere near 450w with a system like that. This is especially since power estimations show maximum values at best, essentially the highest value that could occur when running stress-testing programs like Prime95 and Furkmark simultaneously. If you see techpowerup's review of the GTX770 for example, during gaming load the average power consumption of the card was actually 160w.

 

As a result, power consumption during gaming load would probably average around 300w, slightly higher whilst rendering and such. Since the unit is of high-quality anyways, there's really no problems with running it at that kind of a load for extended periods of time.

 

On a side-note, why are you getting an AIO CPU cooler if you aren't overclocking anyways? Sticking with the stock unit of getting a cheap air cooler (if you wish for silence) would easily suffice for a stock Ivy i5.

Yes, I am not thinking of overclocking, since I knew the power limit of the PSU was about to be reached, (on my estimates); Also, I won't be using the coolers fans, since according to linus' video about how to build in this case I only need the radiator and its pump, the only fans on the case, will be the one that comes with the case, the PSU, and GPU.

 

And  thank you for your very complete answer, I'll build this pc, if I am not lucky and can't run that graphics card I have a 660ti in reserve :D (I really hope I am not forced to use it though D: )

I have already stress tested the CPU, since I have my pc on another mITX case, I don't have the 770 but I can always stress test it on another computer ^^, about the AIO cooler, I wanted something more silent, that's why I changed it

 

 

I am thinking about changing the HDD for a green one , it will help with lowering overall consumption, will it impact too much gaming loads and stuff?

It will lower power consumption, but you will notice reduced random I/O performance, and a very small sequential performance reduction. Game loads will be a little slower but not noticeably.

Thank you :D, I normally only surf the internet and play games, so i think I should be ok.

TDP is not power consumption lol.check wiki.look at this for ex: 

-total system use @ stress test 48 W at wall. only the i3 2100 TDP is 65W lol.

 gtx 770 max is 180W

 

and the psu is more than fine for it here a video with Linus using it with i5 K ,gtx 670 with OC,STRESS test and everything

power consumption for the i5 3570K system was 85 watts idle and 160 watts load,with the graphics card in it.

a way to estimate the power consumption of the cpu is do prime 95 load-idle = cpu only

because during idle cpu will be a very small part of the power consumption.

160-85=75 watts.so is it wrong to use the 77 watt tdp given by intel,I would say no in this scenario.

 

as to the 180 watt power consumption for the GTX 770 I used the MAX load consumption,as in furmark. because while it's not a realistic  representation it sets the bar.

meaning,if it can run stably under furmark + prime95 simultaneously,temp and power consumption wise,you'll be fine in real world scenarios.
