Area-51 R2 replacement PSU

Area-51 R2 replacement PSU

Hello,
I have a 1500w psu but it failed on me yesterday, Its out of warranty and ive heard DELL dont supply these any more(im still waiting to hear back from them).

What I wanted to know is would there be any issues from getting a 850w psu as a replacement instead? Im only running one graphics card off it and with the rest of the components I dont think it will even get to 850w as that was the base option available when I got the machine.

Also if I cant get a replacement from DELL, what should I look out for when trying to source a 3rd party one for myself? 
I heard I might need to replace all the power cables inside for lower wattage ones.

800GY is the part# for the 1500. Most Texas (USA) vendors get their Dell surplus parts from Dell HQ in Round Rock Texas, so here's a used one ... the 850s always work in a pinch, will run dual-1080 but aren't certified for dual-Titan / 980ti / 1080ti. The factory case harness is only meant for the 850 / 1500, it must always be pulled out when changing the psu. New aftrmrkt psu must use the cables that come with it. Corsair Hx 1200i / Ax 1200i & Ax 1500i will not work with the factory motherboard due to a proven Power OK timing issue (proven at Alienware China factory via Corsair employee). All other brands should work, all Corsairs should work if you've swapped in an aftrmrkt mthrbrd. Based on prices, I'd get the surplus 1500 (with 30day return policy)

thanks for the help, unfortunately they dont ship internationally and im outside the US, but luckily after a few long phone calls with customer support Dell are sending a technician out to look at my machine. So hopefully they can replace the part for me and I can avoid having to find and re wire a suitable alternative .

Thanks for the part numbers, just in case mine ever fails :-)

Hello i have am alienware area 51 R2. I have 2 Evga 1080FTW2 with an SLI bridge and i'm looking for a power supply that will work with the motherboard. I had 2 evga 1200 and neither one worked. I've been researching and see that the power supply upgrade is a major problem for this machine. So to my question will my 850 power supply work without any problem if not what would someone suggest a power supply to use that has had this same issue with this version on the area 51 R2?

The stock 850 was said to work with 980Ti without an overclock (if it restarts, then it's too much card for the PSU). You're the 1st to say an EVGA didn't work (the 1300G2 & 1600 G2 P2 T2 are said to work). Ax1200i / 1500i Hx1200i do not work --> but the Hx1000 / 1000i does work

Typical scenario for PSU that will not work, is to push power button and only get a 'click' (Bios timing issue)

Literature for the Aurora says the 850w can power (is rated for) two 300w cards, that is of course when paired to a 95watt CPU; stock 850w is a multi-12v-rail design, & because you have an extreme Intel 140w, the inclusion of 250w cards puts it at its boundary; you might look into an 850w single 12v rail design & may have luck, but I'd probably try for a 1000w power plant minimum, I like Seasonic (but haven't seen someone try one yet), & look into 1300 G2, Hx1000 ... a part of me wants to have faith that a 1000w EVGA should work > buy your psu from a place that accepts ez returns 

I just shopped Newegg's full 1000w list, nothing jumps out at me short of the Seasonic (Prime) Corsair EVGA models as something I'd invest in, the RM1000x 1000i look ok @$200 > almost all of the power supply swaps I've seen were paired to new aftermarket motherboards, so I'm not in a good position to say what works with the original alienboard > the 1500w 800GY is seen on eBay sometimes & is compatible with the 850watts case harness (when buying the 800GY bare chassis w/out cables), maybe see how far you can get with the original 850 til u track the 1500w down

edit: not that I know it'll work, but EVGA has a new 1000w G1+ just released, & may offer an ez return policy @$190

edit 2: see Newegg 1000 G1+, in stock $190, liberal return policy

Thanks for the reply. I haven't seen anyone that has had any luck with an after market PSU upgrade. The machine came with the geforce 1080 and i replaced that with 2 Evga1080FTW2 and a Nvidia 3 slot bridge. Everything seems to be working ok, I just wanted to make sure the Psu would be able to handle it without any future issues.

Ah, I mistook your dual-1080s for Ti's, that's the 2nd time I did that this year

Your 850 (like mine) has a 48Amp Grfx rail x 12volts = 576watts available, 792watts 12volts max >< 1080 FTW2 are 215watt cards, expect higher output when overclocked but you seem to have headroom (Tom's Hardware has seen 375watts or so out of the aftermarket Ti, which is why they push the limit of the 850 in SLI); if the 850 restarts or shuts down, then yes, soften the overclock or think about a replacement, the Hx1000i has been vouched for, 1300 G2 also; if the 1200 P2 (both of them) 'clicked' & did not work, it is either your personal user install error (for instance, none of the opriginal case harness cables should have been tried since they aren't compatible) or is installed correctly then = proof-positive that model can't work & should be avoided, thus part of the list of models to avoid like Ax1500i 1200i and Hx1200i), otherwise, I wouldn't rule out other EVGA models in the 1000w range just yet

Keep an eye out for 800GY in the near future
