Hi, i just recieved my 3850 pro today and i notice it comes with its own power lead, I havent installed it yet and was wondering if it needs the power lead fitting or not?

Does it just need fitting when in crossfire?

I am NOT(as you can gather) very up on graphics cards so sorry if this sounds silly

Your help is appreciated - as always

Regards Jody
 
does your PSU have a connector that is identical to the one that the power cable features?

does it have black and yellow cables?

does it fit into that 6pin connector on the card?

one end of the cable yes
black, yellow and brown
looks like it at one end but it then goes into 2 4 pin white plugs

it will as jimmyboy2008 say be the power connector for the card, without it in you should not get any image up

you use the one your PSU has as the oen in the box is an adaptor
 
You won't need it becuase your PSU has pci-e conenctors (2 probably not sure I have the VX550), older PSU's (pre pci-e) don't have this power connector so they supply molex-to-pcie adaptors with pci-e cards.
 
Ok, thanks for the heads up, appreciate it. Didnt realise that they didnt take power from the pcie anymore
 
If you don't have a PCI-e power cable connected to your current PSU (I have the HX620 which is modular - assume the 520 is the same), you will need to find the bag of cables corsair supplied with the PSU and locate the 6pin power connecter (same both ends). Plug one end into your PSU and the other end into your graphics card.

yes found it mate thanks
 
Do these 2xmolex -> 6pin PCIe cables have to be used with dual rail PSUs ... I'm thinking of getting one of the OcUK 3850's but think my PSU only has a single 12V output ... it claims to supply 17A ... is that going to be sufficient or do I have to factor in a new PSU as well!
 
No, the 2 molex are not the same (male and female) ones used for pluging other cables into, daisy chain or whatever you call it. You don't use both molex. As for single 12v rail at 17a you will probably need somin stronger though im not sure for that card, somone here will know.

Look at the sticker on your psu, it will list all the rails.
 
Probably didn't make myself clear ... what I meant is can you plug the two molex plugs into two molex sockets on the same daisy chain (or more likely plug them into a power splitter!)?

I'll check my PSU when I get home but it does do 12V x 17A thats 200W ... thats a fair overhead over the 75W the card claims it needs.

N.b. FWIW I'm currently powering a 6800LE AGP card via a molex with this PSU
