My Dell XPS 8700 started having random power failures after i upgraded the RAM to 32 GB. So, I'm assuming the extra stress on the PSU is causing it to fail. SO, my question is what PSU can I buy that is an upgrade that has plenty of power for a future/potential GPU upgrade?

Or is it best to upgrade both the GPU and PSU at the same time?

Though, I really don't want to spend that much money on the Dell.

Your RAM upgrade is likely unrelated to your PSU problem, RAM takes barely more power to run.

That said yes your PSU is failing, A 550w PSU opens to up to most mid to high mainstream cards which would work with your PC.

The XFX TS 550w, EVGA 550G2, Seasonic S12II 520, are all excellent choices of PSU that will let you run as high as a Nvidia GTX 970 or AMD R9 390.

Just curious why you say my RAM upgrade is likely unrelated to my PSU? I ask because the advanced tech guy at Cruicial told me that the Extra RAM I put in demands more power and probably put it over the edge. I put my old 12 GB of RAM back into the PC and it runs fine. It's a very frustrating problem to troubleshoot. THe Tech said also that it also could be the motherboard but highly unlikely.

He's wrong. The RAM literally pulls in a watt or two.

Have you put the old ram in and let it run for a while?

It could be a motherboard issue with the new ram he is correct, I doubt it too.

You should run event viewer and see what error happens when it crashes. If its Kernel power 41 its likely the PSU is having a problem.

thing I wonder is does the board / dell proprietary bios support 32gb of memory ?? looking over at deel all they give in any [really no] support pages is 16GB Dual Channel DDR3 1600MHz - 4 DIMMs

nothing on any max amount or anything but what ''they'' offer ?/ so if dell has a 16gb limit in some way this could be at issue ?

http://www.dell.com/us/business/p/xps-8700/pd


unless you found a official upgrade page for that model telling alls well.... ????


what ever all this is getting at ?? looks like 24gb max ??

''Thank you for your response, Unfortunately the XPS 8700 comes with a maximum configuration of 24 GB only and it cannot be customized

http://en.community.dell.com/support-forums/desktop/f/3514/t/19525149


don't forget if your using windows 7 home it limited to 16gb anyway ??

don't know man, try back down to the 16gb and see if it still has that issue of them random power failures .

if not and seems fine call it incompatible if the same issue maybe a board or psu failure ??

best I can come up with

good luck

Well according to the specs on the Motherboard ---
See: file:///C:/Users/Bob/Downloads/dell%200kwvt8%20motherboard%20specs.pdf

SPECS:
4 x 240-pin DDR3 DIMM slots Supports Dual Channel
DDR3 1600/1333 MHznon-ECC, un-buffered memory
(Max 32GB on 64-bit Operating Systems)

I'm running Windows 7 Professional 64-bit SP1.

So, the mystery continues...

what mystery ? you resolved by the best answer ??

and ya , the board may support 32gb with 4 slot at 4x8gb sticks don't mean the dell bios will you dont find it funny that dell them selves don't offer that as a factory dell upgrade ?? why's that ??

go here and select the 1000$ xps then use there ''customize and buy tab

http://www.dell.com/us/business/p/xps-8700/pd?dgc=BA&cid=296138&lid=5662113&acd=12309220187294297&ven3=475102786477073791

choose memory and see just 16 gb is all

http://configure.us.dell.com/dellstore/config.aspx?oc=frtlwgs111rsb&model_id=xps-8700&c=us&l=en&s=bsd&cs=04


this is why we do ''custom'' build and not junk proprietary prebuilts


dell don't care about you upgrading there in business to sell whole computers and if your computer is not good enough you throw it in the trash run to wal mart and buy there ''better'' model


dell only guarantees there computers to fully work with what they put in it from there factory as you bought it out of its box . not a drop more . any thing you do over that is all your own risk


so it no mystery at all , its dell he11

good luck and enjoy
