PSU for itx

[horaciob92]

a PSU of 12V/5A Adapter and 120W DC Board is enough for an i7 6700k without oc with ssd, 2 sticks of ram, 1 fan 50 mm? Or would the i7 7700 or 6700 be for that psu?

The case is as follows:

12V x 5A = 60W, not enough to run the CPU alone, never mind a whole system.

That's seemingly a worst-case scenario, but it's important to realize that you get power SPIKES in any system above what charts like this show so 120W is probably not going to work.

Not sure WHY you would need such a small case, but usually for an HTPC (media) or basic browsing/light usage PC a dual-core (i3) is sufficient.

*Heck, the G4560 is pretty cheap and is a 2C/4T processor excellent for light to medium tasks.

You are right, the use will be as a development workstation with the use of applications such as visual studio, android studio, web development, etc.
The following configuration would be enough for these tasks:

• 
  ■ asus motherboard b150i pro gaming wifi aura
  ■ Intel - Pentium G4560
  ■ 2 modules 8Gb DDR4 to 2133 Mhz Kingston HyperX Fury
  ■ 1 SSD
  ■ Source 12v/5a
  ■ No dedicated graphics , use the built- in plate .

Or better look for another itx case and go for the i7?

12v 4500 mAh how much would it be?

12v 4500 mAh how much would it be?

P = V * I
4500mA is 4.5A.

That would be 54W, 6W less.

And this psu would be enough says it's 450w generics?

Unless I'm misreading the tiny text on that picture, the total is closer to 200W. That appears to be one of those instances of the big number in the model being nothing more than a model number unrelated to ratings. Out of that, only 8A (96W) is on the 12V rail, which is going to be tight for a high end CPU + MoBo + RAM + HDD/SSD + fans + ???.

If only it would be high end CPU + MoBo itx + RAM + SSD and 60 mm fan. Or is it too tight and risky? thanks

I'd better look at another case itx and use an evga 430w PSU that I have

The CPU alone is ~100W worst-case peak on the 12V rail at stock clocks and voltage, likely more than 100W once you add VRM losses. Once you add the other loads and a modest safety margin, you're looking at 150W (12.5A) on 12V.

Personally, I'd rather go with a case that takes an SFX or TFX format PSU than have an external AC adapter. Not the greatest selection of PSUs, but still much better than a high power AC brick and pico-PSU or equivalent. Of course, nothing beats cases with ATX PSUs for convenience and ample choice.

 

[photonboy]

SFX is a good choice.
It boils down to how PORTABLE this PC needs to be.

Keep in mind FAN NOISE can get loud (or at least annoying) with a small fan if the case is very small. The Mac Mini for example is tiny but the fan can whine under load.

Same for many laptops.

Since processing power is important I'd concentrate on a case large enough to fit a small Noctua CPU cooler.

Perhaps use PCPARTPICKER.

But..
Visual Studio etc?

Can that even benefit from more than a G4560? Better ask about that first, or monitor with Task Manager to see how much of your CPU now it uses under load.

While code-writing? Not that much. While building a project? Of course. This isn't much different from 3D work where the CPU doesn't matter much until you get to the point where you need to render with the ray-tracing engine to see how the final output is going to look instead of relying on regular DirectX/OpenGL render used for most of the work until then.
