I'm wanting to confirm before I hook up my new card, which power cable from the psu to use. I have an Alienware Aurora R4 with an 850w psu. It has P14, P15, P16 and P17 six pin connectors, with a 2 pin connector wired to the P15 and P17 connectors. The card I bought is an ASUS Strix Gaming R9 380 4GB with an 8 pin connector. Can I use either P15 or P17 connectors and use the 2 pin connector that are attached to them? Or can I use a 6 pin to 8 pin adapter?
Solved! Go to Solution.
Hey Chuck, glad to see you settled on a nice card. My R4 is no longer on the original power supply, I don't have access to cable # assignments, but I doubt we need them
R1-R4 875watt / 825w 12volt max power supply has two vid-cables, each on its own 12volt rail
- we need to engage both 12volt rails -
Stay with me here. Blu-wht has a primary 6pin & a 6+2 jumper, so does blu-ylw:
in my A51, P18 is a primary 6p, P19 is the 6+2 jumper
- this card is now operating off of the paths of least resistance: the primary 6pins -
In your instance, if P14 & P16 are the primary 6pins, insert them, then borrow 2pins off of P15 / P17 when & where needed. Got it?
this HD 5970 needs 6p + 8p power
... can you handle the truth of it Chuck ...
get her connected, post me a photo of your job well done
engage both of your 12volt rails & release the Kraken
Tried both combos of F14 with 2 pin from F15 and F16 with 2 pin from F17. Computer turns on and both fans spin on vid card, but never get anything on monitor. Not even the alienware skull for BIOS.
Tried both of these. The vid card has a DVI-I (which i used) and a DVI-0 and two HDMI slots.
The Kraken has destroyed Argos!
this is a snip of an email notify I received but I do not see the message itself, it's in limbo
Fussy cards aren't my especiality, but I might try to turn off or on the PCI-E Gen 3 in the bios; if yours is of then turn it on, if it is on, turn it off, see if you get video output. I might try a different monitor &/or monitor cable, that goes for simply unplugging your monitor there for a minute then plug it back in. Report back
you weren't kidding, just a solo 8p
Per Newegg it is a 190watt card; my notes say R4 was sold with dual GTX 780s which are 250watt cards each, (what is the maximum hardware can Alienware Aurora R4 support?), so you're well within specs, meaning if one cable powered a 780 then one cable should power a 380
PlanB: dual 6p -to- solo 8p
search 'EVGA cable' on eBay, score a black n' for ~$5 - $8
dual 6p y-split cable has been used to good effect in Area-51 for HD 7990 / 295 X 2
if all else fails Chuck, get a y-split, engage both 12v rails in that solo 8p
... re-release the Kraken ...
Thanks again for all the input! Not sure what happened with my post, but I put pics in it, so maybe it's waiting on admin. Basically, the system seems to power up and run smoothly, the vid card fans spin, but I get nothing on my monitor. I can't even get to the BIOS option. I get no beeps to indicate an issue, just the smooth purr of fans. My fins on the top go up and down like normal on start up. I removed the coin battery on my motherboard for 5 min and tried again. I jumpered the pins on the motherboard and tried again. Always the same thing. After reading one of your posts, I removed all four sticks of RAM and booted up and then the motherboard started beeping at me. 2 beeps. So it's not a completely quiet motherboard. I also unplugged the mouse, keyboard, speakers and ethernet cable and tried again. I wish I had another monitor to try, but I do not. I will try and see if my computer store has a dual six to eight pin adapter. Perhaps another cable. I would think, that even if the vid card is not powered correctly or even if it's toast, I should be able to get to BIOS? I shall continue to look and try some things. I'll keep you updated.
Tried every combo I could think of with power cables. I have not tried the dual 6 pin to 8 pin. My computer store did not have one, so I'll need to order one. I swapped to an HDMI cable from the card to my monitor, but still no BIOS. I replaced the CMOS battery with a new one. I get no initial beep when I turn the computer on, I normally get the power up beep, and it won't send anything to my monitor. The only thing I have not tried is loading BIOS externally. But I'm thinking my motherboard needs to be replaced.
I'm not so sure it needs replaced. Please place your original card back in, go back to square one. The new battery swap will have imparted all BIOS settings to revert back to 'default values', which may have led to this latest puzzle piece of not beeping. What I meant last night, was if you were to place your old card back in, then check your bios PCI-E GEN3 setting, change it, then place new 380 in there. Please make a companion post on AlienArena, General & TechSupport, lots of gamers / card swappers over there & I'm not a 'no video output guru' with a new card; I don't make card recommendations to people; half the reason is if it gets there & fails to produce video, I don't possess wizardry to get video from it, I'd feel bad for saying a card is ok if it gets there and flops
I agree with you, that in the scenario where a new hard drive is in place & a Windows DVD is inserted, you should get video, get a BIOS screen a least, in preparation to install Windows. Sometimes it is a monitor needs unplugged for a minute then plugged back in, a monitor needs replaced, a monitor cable change can help at times, I wish I knew. Try your old card, test the motherboard 1st
If I may ask, does the computer boot with your old graphics card? And do you have the latest (or more up-to-date) BIOS?
You could probably use the old graphics card to make adjustments to the BIOS settings and see if anything works (and potentially update the BIOS if you haven't; flashing the BIOS to the latest version wouldn't hurt if you have it already).

Tried the old Radeon 6870 card, but to no avail. That card's fan spins as well, but nothing at the monitor. I've tried DVI and HDMI. Prior to losing the system I had upgraded BIOS to A11, which was per the Dell site for my service tag. Both cards give me the same results. I did make a post on AlienArena yesterday, Cass-Ole. I shall remain hopeful.
Thank you for your time,
