Alienware Area 51 R2 How to Power Supply Swap to Third Party

en.community.dell.com/.../19675279

Looks good, Here is my thread on the Area 51 upgrades, if you haven't already looked at it http://en.community.dell.com/owners-club/alienware/f/3746/t/19675279

Nice work and thanks for posting.

I wonder why the Corsair PowerSupplies are not working (W8Lift's thread says the same).

So, you think the stock Dell-AW 1500watt PS is ok? ... just pricy, right?

Think the Delta PSU (OEM) is garbage, only one year warranty, no added features like ECO Mode plus it is so ugly. Think Dell should revisit the PSU's. It sticks out so bad in this case.  

I believe the PSUs in corsairs senses a fault, and shuts off. I played with the test button and it kept tripping like there was a short in the system. (obviously there wasn't) but it only triggered with the motherboard power connected. 

thx happy to help out people who paid PREMIUM for that nice Machine :),

i think the both DELL OEM PSU 850watt & 1500watt are not good at all, the Prize Tag of the 1500Watt is a bit high, if you compare it to the all WORKING EVGA top dogs PSU . 850WATT 1000WATT etcc....

for my needs iam planning to add a Second Titan X , so the eVGA 850 Watt is Rock Solid for my Specs.

For Testing if the OEM PSU Performs well (Pure Power to the TITAN X )

Results i did 3 TEST Runs with Unigine Valley Benchmark set to Extreme HD 

Everything Set to Normal , no OC for the CPU, no Over Voltage the Ttitan everythiung STOCK Speed.

after 3 RUNS with the OEM PSU i had > 3890 > 3897> 3932 Point and a Max FPS of 172 to 181

after 3 RUNS with the eVGA PSU i had > 4093 > 4102> 4129 Points and a Max FPS of 186 to 192

Conclusion 

With my TITAN X 12GB Evga Superclocked i put in the Middle SLOT to get Full PCIe x16 x 16 V3.0 

the OEM PSU made a COIL WHINE like a Formula 1 Engine ( on 1st SLOT and the Middle SLOT)

NO the DELL OEM (DELTA PSU ) are  not good at all ! 

after 2 days i got my Area 51 R2 i called Dell and told them about the PSU , they sended me in 24hrs

a NEU Replacement , that had the Same Noise , 

Thx for sharing :)

When you installed the Samsung pro ssd did it detect it just fine without having to change any bios settings ?

ehmm, what do you mean ? 

i installed 2 Standard 2,5" Samsung 850 PRO SATA600 Drives, there is nothing to change in the Bios ! they are standard SSD drives .

i you mean Raid 0 Setup, you must set the bios SECURE boot = OFF and than you CTRL + I in when the PC starts up and Setup the SSD RAID ! 

but Intel RAID does not Feature TRIM Support ! that is not so good after a while 

Which cable from the psu goes to the front USB / audio jack small front board ? For new psu

Litho bro , thx for sharing :) thinking about getting the evga t2 1000 watt psu did all the cables with your evga psu unit reach fine to the hard drives etc ? Does the power cable to the DVD / blu Ray drive work fine from the new psu ?

You had another qwestion from another thread, I'll answer that here.

it'll be the 4pin Molex peripheral which powers the blue FI/O board

JohhnyGuru: #1 test sight

The circled connex are the device end, the hardware end: since a power supply front panel can have any endless combination of pin patterns? You use the approved cables. That is because the manufacturer has ensured that the sqware end is wired in all of the right slots. It's the sqware end of the cable that dictates what the device end does, ultimately.

Those cables above may work for all 850 1000 1300 1600 G2 P2 T2, but may be wrong for other EVGA models, certainly may be wrong for other brands. Let's pretend you plug that black 4pin into the T2. The device end will read on a voltmeter as 5v-ground-ground-12v, ok? It has to.

Now, pretend youi plug your case harness 4pin into it (which has a 6pin modular connector). It might read 5v-grd-grd-12v & if it did it would be ok to use it, but, the sqware end has its own unique wiring scheme, so it could just as easily read 5v-12v-grd-grd or grd-5v-12v-grd ... if it did, you would endanger your stuff, maybe your life who knows.

What we do in times like this is a bench test, make a sketch of T2 factory black, compare it to the case harness, and make any changes at the sqware end, which means back the wire out & place it into whatever correct new slot it needs to go in. I do that kind of stuff, find me here if you haven't already, where I show my hand-made case harness: Alien Swap

I took a factory Antec 1300 cable set - hand-worked it - to be correct for 1500w Delta

All those many wires had to be re-organized in order to work. That is why your factory case harness may not work with the T2. You test first, on your dining room table for instance, nothing plugged in but cables - probe them with a voltmeter, make any changes to the case harness cables, as I said. Antec cables are $25 a pouch, shipped. A steal. I don't have an Antec 1300, I just bought the pouch, separate. But if I did have an Antec 1300? I could take the factory case harness we all have, and rebuild it to work with the Antec. I'd have to re-do the whole thing. At the modular 'sqware' end. Once it's correct, the device end works (=

The same as you might have to rebuild your case harness to match a T2. If you did? Your case harness then might be good for 1300G2 & the 1600 line-up. I hope that makes sense. Too many users online think that a cable is a cable, that all modular power supplies are somehow universal. They are not.

Approved cables only:

• either from the manufacturer
• or your own hand tested cables
• or your own hand rebuilt hand-tested cables

cables that pass the voltmeter test can be used

cables that fail get rebuilt, reworked, retested

• if ok? they're safe
