Need instructions for spliting power from a 6 pin PCIE to 4 pin molex.

As I said and Crashman said, check the rear layout of the PSU. And get your Dremel ready, because I think you will need it. I haven't done it, but it shouldn't be that big of a deal to hog out some metal from the back of the case.
 


That's why you buy the expensive PC power and cooling one specifically for the Dell. The really irritating point here is that Dell did this intentionally to force you to get the PSU from them. At one point several years ago they even mis-wired the PSU so that if you bought an ATX PSU you would blow up your system. Thank God they stopped doing that.

I say get a Dremel and go to town, after you confirm the physical size.

Dude you got a Dell! :lol:

I know it's not funny...I couldn't help myself.
 

But couldn't it still work though? Using standard ATX psu's?
The ones they sell at Dell.com are standard ATX and those are put there so that customers can upgrade the psu's.
 

It is, your machine has an open back design that won't intefere with the switch and won't require a Dremel.
 
That's why I said compare them, do a little work, look at the PSU's and see if they will fit. If not, cut away any sheet metal that is in the way. It's not a big deal.
 


Some Dell cases have a large hole that can accomodate a variety of different ATX power supplies, others have a small hole that's cut around the power jack. DellUser1 says your case has the large hole so no worries so long as he's right.
 


Yes, it is, I just looked up some photos

With an open back like that you should be able to fit a "normal" power supply regardless of where the power cable connector is located. The fan should be inside the power supply, so no worries about that either. It's best to get a "standard" part whenever it fits.
 

I mean the cpu fan elimates the possiblity of me getting a dual slot gfx card. Thats why I have to wait for good 3850 512mb cards or single slot 3870s.
 


It's not just the HSF shroud that would be in the way, there is no open expansion slot above the PCIE slot.
There is a guy on the DCF who modified his E520 ( same layout ) to accept an 8800 GTS, by cutting away part of the shroud and making an opening for the exhaust. Do a search on it over there, pictures are included.
 

Well I couldnt do that just yet because I have a 3 year warranty but i'll check it out.
 
I don't know this for sure, but using a non Dell PSU probably voids the warranty anyway. Swapping the VGA might even void it.

Maybe DellUser1 knows.
 
The warranty on the box won't be voided by adding parts, but of course the after market parts will not be covered and when calling for support you will be told to put the original parts back in place.
Cutting it up will void the warranty.
 
Of course it is. I would'nt want to kill my motherboard then not get one by warranty and then of course there are like no BTX motherboards so I would have to get a new rig. Bad idea.
Adding parts dosen't void the warranty but removing the psu I heard does but who cares. If I have a problem, I can switch everything back to normal before a Dell technition comes. 😀
 

That's the way to do it 😀
I still don't think swapping the psu voids the warranty, but why tell em.
 
Ok everythings good now. I just hope my Intel pentium D 940 @ 3.2 won't bottleneck a 3850 or 3870. Because theres another topic where somebody has a Pentium D @ 2.8 and have super bad bottlenecking. To the point where they can't even play bioshock at medium with a 3850.
 
Well I just found out that I don't have enough molex's on my PSU so I have to get a splitter for that and for the PCI express. LOL.

So does anybody think I'll get bottlenecked by the cpu? I have a pentium D 940 @ 3.2
 


I've a question for you ANZstriker92; i have exactly the same problem as you in that i dont have a spare molex to connect to, which is very frustrating! what in the end was solution?

I bought a Nvidia 7900 GTX as it was cheap and better than the 7300 LE that came with my pc but with no spare molex its a bit redundant at the moment.

I now have a spare PSU that has the right connectors for the card but would have to run them througha slot in the back as the rest of the connectors wouldn't fit the set up.

if i run the spare psu externally just to power the card would this be a problem? I assume the card would just draw the power it needed and not fizzle into a molten plastic ball but not 100% positive on this......
 



Hi aznstriker92, i've have exactly the same problem as yourselve with the lack of molex supplys and would like to know your solution.
--
Delluser1 has suggested a SATA to molex splitter which looks as though it'd solve the problem, is this the route you took?

I'd appreciate any help in finding a solution many thanks.
 
you would be better off with the 4850 if your in the uk i would sell my old one for £30 much btter card and i have the splitter lying about some where
