4 Pin Molex to 6 Pin PCI

Johnnythebull · Mar 23, 2014

Hi,

I'm looking to upgrade my graphics card but don't have a spare 6 pin PCI cable so have been suggested to get an adapter.

I'm a bit confused though as I have found 2 different types which use a 4 pin Molex.

http://www.ebay.co.uk/itm/4-Pin-Molex-to-6-Pin-PCI-E-power-adapter-converter-graphics-card-cable-/190814965149?pt=UK_Computing_CablesConnectors_RL&hash=item2c6d754d9d

and

http://www.ebay.co.uk/itm/Trueway-6-Pin-PCI-Express-Power-Adapter-Cable-to-2-x-Molex-LP4-Lead-006003-/190729421313?pt=UK_Computing_CablesConnectors_RL&hash=item2c685c0201

Why does one use 1 Molex and the other one use 2? What one should I be going for?

Any help would be hugely appreciated!

i DO NOT! recommend it if the psu does not have a 6pin pci-e connector that means its not capable of running 6pin pci-e video cards.

It might be okay, but it's unlikely. What's your PSU?

ModernWarfare · Mar 23, 2014

And 12volt rail amps.

Johnnythebull · Mar 23, 2014

Ahhh man! I really want to get an R9 270

@Junit151 I've got a 500w PSU. Can't really afford to update the PSU as well right now.

Junit151 · Mar 23, 2014

R9 270 is a great choice! I am planning on getting another R9 270X 4gb for crossfire (270X crossfire beats a single 290X)

But anyway, 500 watts should be fine, but is it like a brand name PSU? It would be nice to know who made it.

ModernWarfare · Mar 23, 2014

WAIT. what are the 12volt rail amps?. Also im guessing its a no-name Classic psu.

Johnnythebull · Mar 23, 2014

That's pretty cool mate! Some serious gaming to be done lol.

I don't think a good brand to be honest. I just opened up my case but can't remember the brand name, but wasn't a Corsair or anything like that.

@MW Sorry mate, not sure what that means! All fairly new to me (PC gaming) so still learning.

Junit151 · Mar 23, 2014

It would probably be a good option for you to go with a builder series Corsair since you don't have a fairly large budget.

That's gonna set you back about $60 but you're gonna need a proper PSU to run a decent graphics card.

It seems like you and I had an identical situation

I found this all out for myself, there is just no way to get around the need for a decent PSU.
(I managed to get a good holiday deal on a TX850M but it is like $80 more now than what I got it for

That's so annoying

But I appreciate your help, both of you. Looks like it's back to saving up for me!

@MW Just had that one up funnily enough. Should I be going for the fixed cables or semi modular?

geofelt · Mar 23, 2014

Every ul psu must have a data plate which tells the +12v amps.
Normally, a 450w psu will be sufficient.
Not having a 6 pin connector is a red flag.
But, since your psu seems to be working ok, go ahead and try it.
I might suggest a GTX750ti which is close in performance, and only requires 20a and a 400w psu:

geofelt :

I was looking at the 750ti before the R9 270...But I'm worried about my PSU now.

ModernWarfare · Mar 23, 2014

the semi-modular is better for cable managing

.

Johnnythebull · Mar 23, 2014

ModernWarfare :

Thanks mate. I'm tempted to buy that as well now! I was set on getting the R9 270....Yolo?

ModernWarfare · Mar 23, 2014

consider the r9 270 it is overall better than the gtx 750ti.

Johnnythebull · Mar 23, 2014

ModernWarfare :

I'm going to get the R9 270 if I do buy a new graphics card..I mean't I'm tempted to just buy the Corsair PSU too now lol

ModernWarfare · Mar 23, 2014

you must get the psu with it.

ModernWarfare · Mar 23, 2014

50watts less but around the same amps it should power a r9 270 just fine Recommended.

ModernWarfare :

If I buy a new PSU too, will it just be the case of plugging it all back in?

ModernWarfare · Mar 23, 2014

yes nothing difficult.

Johnnythebull · Mar 23, 2014

ModernWarfare :

Thanks mate! I think I'm going to give it a go

Junit151 · Mar 23, 2014

Johnnythebull :

When I got a new one, it was easier to work with than my old one. New custom build parts are made to be easy to work with.
