Just looking for some help finalizing

[SilicateWielder]

Hello all,

 

I have been in the midst of planning a portable PC build since the end of August. I have made some progress in terms of obtaining parts and preparing the case for modification, however I am returning here for further aid regarding the build.

 

I've got a large majority of parts ordered already, however I'd like some help selecting some final parts, particularly regarding cooling and a power supply, here is my part's list so far.

 

I'm using modified briefcase as my chassis, I'm debating on whether to use a SFX formfactor PSU or purchasing a DC-ATX type powersupply and a 250watt power brick. My budget is strictly $80 and I cannot go over whatsoever.

If you want a sfx powersupply you should consider something like the Corsair SF450 at around 80 - 90 dollars, i'm not personally familiar with many SFX psus though, I think Silverstone also has a decent 450 watt unit for around 60 bucks

I'd recommend the power brick and having it outside the "case" - I'm not quite sure how you want to handle the heat inside the briefcase otherwise.

That's what I have been considering, however it's near impossible to find any power bricks capable of delivering 250 watts of current at 12 volts. I have a 150 watt Xbox 360 brick but no bricks with any more capacity than that.

 

If you know where to obtain a brick capable of delivering a constant 250 watts that would be greatly helpful.

 

EDIT: I may be able to set up some wiring to get power sources in parallel?

Silverstone ST45SF-G and Corsair SF450 are a touch over budget, but probably the best choices. Since you are working with a hard budget cap, you could consider SeaSonic SS-350SFE or SeaSonic SS-300SFD (http://www.silentpcreview.com/article286-page5.html).

 

Presuming the intake fan is open to the outside and airflow is not restricted, none of these units should contribute significantly to heat inside the case.
