Another BC 250. The "easy" one.

[AlienALX]

OK so there has been some downtime on the GECK due to my mate being busy fixing family cars and etc ! The CNC parts are now all complete, so that will resume shortly.

However, you will note in that thread that I actually bought two AMD BC 250s. Why? not quite sure, but with hardware prices as they are now I am bloody glad I did ! The second one was super cheap. £72 IIRC.

Well any way, I had all but forgotten about it until I was doing the Alienware mod and conversion. I then came across these things.



The Alienware Graphics Amplifier. These were made years ago, and could allow you to fit a GPU into them and use it on your AW laptop or Alpha Steam machine thing.

Well this one rocked up broken apparently and missing a cable, so it was dirt cheap. £30. I could not even buy acrylic to machine into a case for that. This is what they look like inside, and they include a 460w PSU so I am hoping it tests good.



This is the one I bought.



It was the wind tunnel design that caught my eye. I want to fit a larger fan (its a 92mm atm) and then I just need to cross my fingers and hope it will fit. It *should* going on the specs on the dimensions but I have a rotary tool and I am not afraid to use it !





Hence why I said it is the "easy" one. Let's just hope it is lol.

OK so this is looking like it could be too good to be true lolz. It fits like a glove. I am pretty sure, though, that I will need to solder the wires into the back of it as with a EPS in it will be too tall. Other than that though? looks like minor modding will be needed and a cover plate for the back.





I've heard bad things about the stock fan. I hoped I could fit a 120 but I don't think I can. This was about £12 IIRC.



I will try and duct it somehow. I got this because the PSU only has two 8 pin PCIE so will need modding.



I will take those from the 24 pin. I also got this, as seems customary lol.




Now from the look of it the worst thing that can happen now would be if the PSU was dead. I have another, but I would rather not butcher it as it is very high end. I'd need to be really unlucky for the one in there to be dead, though.

Time to poke the PSU after jump starting it. Fan spins up, light comes on. Do we have 3.3v?



We do. How about 5v?



Yup, so for all three....



Sweet. That saves me a few bob. I should have had more faith, Dell PSUs are usually excellent.

 

[AlienALX]

lmao. I am amazed at the Dell PSU.

See, I could have sworn the BC 250 needed a 12v EPS. But then, that is the problem when you haven't touched one in about two months. I wondered why it needed such a shove.

It turns out it is actually a 8 pin PCIE, and how I did not blow it to kingdom come is a mystery. Dell PSU = good. It refused to start.....

 

[AlienALX]

OK so I tried to upload photos last night but the site was down. I've now done more !



That's all the plastic crap clearanced. Problem is I need to cut a slice in the metal where I have circled in yellow. That needs to be done outside, so can be done tomorrow. PSU is done.



And £6.99 got me a bugger load of latching switches.



Pre wired too which is nice, as they can melt when soldering onto them.

OK so the 90 deg stick out on the IO was getting in the way. So I cut it off.



Left a bit of an edge poke there. It's all been filed, but that 3mm or so poke was for this. It now slots in where a GPU would.



And so.



And the area that needs removing for it to sit down where I want it.
