Hi everyone,

First off, sorry if I say something stupid. I'm probably not as experienced as most of you are.

I recently took my PC in to be repaired and they said that the issue was that the powersupply was losing power intermittently. There was a brief note at the end that I might consider buying a new pc, and that bothers me - I really don't think the issue is so bad that I need a new PC altogether. I could be wrong, but apparently my motherboard, ram, graphics card, CPU, hard drive etc. are all fine and I'm just really not in a position to drop a couple of thousand dollars for a new machine right now.

Basically, I'm afraid they're trying to swindle me into buying a new PC, and I'd like to go in with some knowledge. I've emailed them to ask if I can just buy a new power supply and have them replace it, but I'd like to be prepared for pushback. They did say that they had some issue running diagnostics as I have a unique power supply and motherboard.

I called the service line and they said that it would not be possible to replace because it has a 'unique' power supply. I tried to ask what the issue was - physical dimensions, mounting, connectors - but it seems the poor customer service girl isn't the technician so I can't really press her for that info. The 'unique system' thing sounds a little bit like an excuse. They seem to really be pushing for me to buy a new system, which sounds like bull to me. The customer service girl told me I could come pick it up (which would mean paying the repair fee, when it hasn't been repaired) but I really don't want to do that now, since once I pick it up the repair is 'done' and the repair cost is supposed to include the cost of installing any new parts (like the power supply). Planning on going in person to speak to the technician and make him explain to me why it's apparently 'impossible' to replace the PSU.

Basically, I'd like to know:
  1. Does the r4 have a proprietary powersupply? If so, this could explain why it is hard to upgrade?
  2. Have R4 owners been able to upgrade or replace their power supply in the past?
  3. Does it sound like the store is trying to swindle me/ doesn't know what they're doing?
  4. If anyone has upgraded their powersupply, would you be able to suggest what to upgrade it to?
Thank you in advance :)

J556T or W299G are the 875watt models most often seen here in the US, the part# for yours is on the side label

J556T https://www.ebay.com.au/itm/Dell-Alienware-Aurora-R4-PSU-Power-Supply-875W-H875EF-00-J556T/352583100317?hash=item521797279d:g:fUcAAOSwtGtcU0pO:rk:1:pf:0
W299G https://www.ebay.com.au/sch/i.html?_from=R40&_trksid=m570.l1313&_nkw=W299G&_sacat=0

It's proprietary, only in the sense that the case harness is unique (which makes it look different than typical PSUs)

To replace: de-couple case harness, back chassis out, put new 875 chassis in & couple the single connector to it https://www.dell.com/support/contents/us/en/19/videos/videoplayer/Aurora-R4-Remove-the-power-supply/U2dDNiMzqLhsE5DYOgD-jkVaQMObmRcP

You can install your own power supply (Corsair/Seasonic/EVGA etc), others have, I did a Seasonic 1000w swap, search 'aurora power supply swap' through google etc, look for Dell.com & AlienwareArena.com posts, lurk in this forum too > https://www.google.com/search?biw=1024&bih=673&ei=QhRZXODQKsan5gKGq4DgBA&q=alienware+aurora+r4+replace+power+supply&oq=alienware+aurora+r4+replace+power+supply&gs_l=psy-ab.3...17345.17891..18085...0.0..0.81.219.3......0....1..gws-wiz.......0i71j0i7i30j0i13j33i10.OlY1kIY_grY

Do you have a basic Aurora or the ALX w/top vents? I dunno if they're messing with u or not, only in the sense that maybe the 875w is tough to source down there

Thank you so much for your fast reply!

I have the basic Aurora, the one with the honeycomb-like top instead of the ALX.

So, would the case harness being unique constitute such a difficulty to replace/upgrade that it's not worth it to do? All other parts of my PC (graphics cards, hard drives, SSD, CPU) are functioning fine, and this feels like a ploy to get me to spend $3000 on a new machine without even trying to fix the old one.

If I'm understanding it correctly, it should be possible to either replace the PSU with the same exact model as the standard, or even to swap to a different power supply, correct? It seems like this powersupply has that one very big single connecter, where as its more common (I think?) to see more smaller connectors. Could this present an issue?

The simplest way to replace your power supply (and here in the USA the cheapest way also) is to buy the same kind --> keep your case harness, buy a bare chassis without cables & put it in there, couple it to old case harness

Popular part#'s are J556T W299G U595G, run those through google, try & find one (also contact Dell/AU if need be), replacing the old one should be easy & cheap & 10minutes to do it, it is worth it to replace with the same kind

Model #'s to search for: N875EF-00 (W299G) H875EF-00 (J556T)

For aftermarket PSU, I put this post together (below) last Fall with links to old posts ... cable management & possible need for a CPU cable extension (the original case harness has custom just-right wire-lengths ... aftermarket has one-size-fits-all cables to deal with so it's a mixed blessing) https://www.dell.com/community/Alienware-Desktops/Aurora-R4-PSU-replacement-questions/m-p/6166197

Replace w/original or buy something like EVGA G2/G3 850w, Seasonic 850, your favorite brand etc

edit: all of these original types have a side label w/a part# on it (W299G below); it's possible this repair place doesn't know where to buy a replacement at or how to find out where to get you one & called it quits; shop for one & see what u find, import one from USA if it's cheaper than an aftermarket type there

Model N875EF-00 (J556T = H875EF-00) which were available in Dell XPS Precision Lattitude desktops & Aurora

FIX THE OLD ONE 1st > they start at $40/US/Shipped here, can't beat that https://www.ebay.com/sch/i.html?_from=R40&_nkw=Alienware+875&_sacat=0&LH_TitleDesc=0&LH_PrefLoc=1&_oac=1&_sop=15

Hello :)

Thank you again for being so thorough and so quick in your responses - you really are a lifesaver. My apologies for being dense, but I've never had to do a PSU replacement so it appears I'm missing some basic knowledge about terms. What do you mean by 'harness' and 'chassis'? A google image search of those terms only confused me more. From context, I presume the PSU goes into the chassis, which is a metal exterior 'shell', looking something like this? Would you be able to give an example of where to buy a bare chassis without cables online, so I don't accidentally buy the wrong thing?

Would buying something like this include the harness, chassis, or cables, or would I have to buy those separately?

EDIT: I was google 'power supply harness' and 'pc harness', which confused me, I realize now that you were speaking about the wire harness. Forgive my being thick for a moment. I understand what you mean now, thank you :)

I see you got your answer
NRHJ9 is the typical part# for the case harness https://www.ebay.com/sch/i.html?_from=R40&_trksid=m570.l1313&_nkw=Alienware+nrhj9&_sacat=0&LH_TitleDesc=0&LH_PrefLoc=1&_sop=10&_osacat=0&_odkw=Alienwarenrhj9&_oac=1&LH_TitleDesc=0
Since you don't need that, you'd look for just the PSU (chassis / case / shell / bare 'unit', lol)https://www.ebay.com/itm/Dell-Power-Supply-J556T-H875EF-00-875W-No-Cables/183639149409?hash=item2ac1bf0b61:g:KFwAAOSw3s9cP0KN:rk:8:pf:0
Your link was for a chassis + harness; if need be, you'd message them if they'd consider selling just the chassis at some reduced cost (& encourage them to sell case harness afterwards by itself at some going rate to someone else / a $40 set might be had for $30by you then they sell case wires for $10)
