Why does the 6pin to Molex has two Molex instead of just one?

[Violet Princess]

So I was building my new pc and I realized that my GPU (Asus Strix GTX 960 2gb) needed a 6 pin adapter from 6 pin to a 4 pin Molex. But as I got it and I was connecting it to the PSU I noticed that it has a dual Molex, where do I connect the one that I don't need? Obviously I made a connection fro PSU to female molex to male molex to 6 pin and from there to my gpu, but there still the second molex from the adapter that I don't know where it goes.
Also, my HDD has a female Molex, where should that be connected? I'm assuming NOT to the gpu. (HDD not connected to the PSU, btw)

6pin PCIE can supply upwards of 75W each (and up to 150W for 8pin) depending on the specs and overall power design and needs of the GPU at-hand.

So that is why if u need to resort to the Molex Adapter, two Molex will be needed to make up the power capacity that a 6pin GPU connector would require.

General rule though is that; if your current PSU lacks enough (or any) 6pin/8pin PCIE Power Connectors, that u should get a high quality (and probaby high output as well) Power Supply that already has those; and more than enough Amps on the 12V line(s).

It's generall not a good idea to go installing a high-end GPU if you lack these connections on your current PSU already. Now if it's a lower-power (low TDP) GPU and it maybe needs a single 6pin and u need to use the molex adapter, fine. But for ones such as NVIDIA x70 (such as 670, 770, 970) or higher, I would never suggest u ever resort to using those adapters. Because if your PSU doesn't have whats required, it probably is most likely not suited for the task of supplying enough power anyways.

Although I think I explained myself wrong. The PSU comes with several free Molexes to plug stuff into, and the reason my adapter has two Molex ends it's just because that's how I got it. Originally, the person that was gonna get it for me was gonna get a single 6 pin to molex, but I went to this other store first and bought that one.

The GPUs just come with the adapters; don't use it. Get a PSU that has the PCIE connectors already.

You can get an adapter to convert your female molex to male to connect your GPU(if i understand what you are asking)

However relying on a molex to 6pin adapter to power your GPu indicates that your PSU isn't up to the job and under load its quite possible you will experience power(lack of) related issues which can damage your components.
I think this is the point the other posters were trying to make also.

Adapt what and why?

6-pin to 2x 4pin Molex for GPUs > the molex there should already be female. The ones on your PSU are male. Nuff said.

Classic case of overthinking and not reading correctly, my apologies.
The OP about plugging in spare molexs makes me think its either troll or he shouldn't be inside a case if he doesn't know the answer.

Looks like your PSU is quite rubbish if it has no PCI-E connectors and only one free molex, best to just swap it out. You can get decent enough 500W PSU with two 6+2 pin PCI-E connectors quite cheap:

Thanks for the advice, I will definetly upgrade my PSU, But I'll have to do with this one at leat until the end of the month. But thanks anyway, I'll keep upgrading and I'll keep you guys updated, this is such a helpful forum.

I don't think my PSU is bad enough to fry the entire thing. So far it's been running nicely and silently, I'm not planning on overclocking anything and I think that if something was gonna fry, it would've already did. Now, I haven't gamed or anything but I have left the thing on for several days without turning it off (transfering files, downloading stuff, you know)
I had several experts look into my computer and all of them said it was fine. (although they did advise me to upgrade whenever I had the chance, probably by, if not the 11th then the 25th) But still, altough not indifferent, I'm not entirely worried.

Your PSU has been "running nicely and silently" because you aren't putting any stress on it. Odds are whatever you are currently using for graphics, be it onboard or a low end card, isn't drawing much power. Your new GTX 960, whilst it is an efficient card, will put a lot of strain on that PSU. It's up to you whether you want to use it.

By all means, install your new card and run it with your current PSU. Beware though, if that thing blows due to being overloaded, then chances are it will take the motherboard and probably your CPU and shiny new graphics card with it. None of us will take responsibility if that PSU goes bang and takes out your hardware. Especially since everyone here advised a new PSU.

Honestly though, if I were you, I would hold fire until I could afford a new PSU. Corsair's CX series is cheap enough and will run just fine with your new card. EVGA also offer cheap, decent enough models, the 500b and 600b. If you can wait those few weeks until you have enough, it's much better than chancing your whole system.

To answer you original question, if your adapter has 2 molex to one 6 pin, you will need to connect both molex for it to work. Else you may not be supplying enough power to your graphics card.

TIP: If a PSU that is around 430w or more doesn't even have a single 6 pin, it's probably a sign that it isn't a great model and is overrated, meaning it cannot output it's advertised wattage. I know your has been running fine and all, but I don't think your current graphics and hardware is drawing much power from it in the first place.

I was playing Tomb Raider on ultra settings at 60 fps, my GPU reached a maximum of 65 °C, (while playing) which I think it's not that bad.
Yes, I understand all the points, my PSU sucks and I should upgrade. Yes I will do it on friday. But I do think some comments are just a little bit overreacted.
So far It's survived:
-A lighting strike
-A Power Outage
-Rendering 1080p (Didn't want to do it, but I had to, for some homework)
-Playing Tomb Raider on Ultra
And, to answere many concerns, it's not that my REQUIRED adapter had two molex ends. It's just that the one I got from a friend was like that. If I had it bought myself ot woul've probably been just one molex to 6 pin and just that. The PSU only had ONE end for the GPU, the other free Molex was an extra, and I figured out later that it was an extra molex to attach a second HDD (as it had both the molex and that one other end for the HDD).
In fact, I know apologize for such a stupid question, as I actually asked before actually going in depth to see what's inside my case.
But thanks for all the replies though.

Want to better test your PSU; run Prime95 + FurMark at the same time for over 30 mins.
If u pass that kind of load, which WILL far exceed that of any "Game" then I would think u should be ok.

But if u going to see those Molex adapters for a GPU, I would please advise (as suggestion by GPU OEMs) not to connect it to the same string of Molex that you have SSD/HDD types on. You will notice a PSU has a string of connectors from a single length of wiring. If GPU via Molex Adapter then connect it to a string not used by Drives. Connect Drives to a seperate string of connectors. That will help ensure the GPU doesn't starve for power; given your PSU is enough for full TDP of your CPU+GPU combination.

Don't worry about it, each string has its own purpose. But thanks anyway.
Still, I'm gonna upgrade this friday. Hope my girlfriend won't mind not taking her to dinner this week :P

Ok well if u'd like to more easily share your system specs; run CPU-Z > Vaildate > click Anonymous > submit > when browser loads up, copy & paste that URL in here; which is public viewable.

And for PowerSupply, just open the case and look on the PSU box area for a sticker, should have a model# on it.

Anyways; u can generally get Corsair CX-430 or EVGA 500B for around $40 USD

My post was somewhat hostile in areas, I do apologise for that. I've seen far too many cases (not on here but elsewhere) where people have learned the hard way about PSU quality. I've even learned the hard way myself with an earlier build many years back. Didn't want to see that happen to you or others, as it really isn't nice to be having to pay for essentially almost a new PC just because of a PSU failure.

Since you plan on getting a new PSU on Friday, here are a few cheap models worth considering:

https://pcpartpicker.com/part/evga-power-supply-100b10600kr

The last one is nice if your budget allows for it and should last you many upgrades.

What are the specs of your system, out of interest?

Thanks for the recommendation, I was actualy thinking of the frist one, but I'll check what can I do to buy the others.
BTW, here my specs.
CPU: Intel core i5 4460 3.2 Ghz
GPU: ASUS STRIX Nvidia GTX 960 2gb.
MOBO: Gigabyte GA-H81M-S2PV Micro ATX
HDD: Western Digital 1TB 16mb
SSD: Will buy later.
ODD: Will buy later:
Cooler: Not needed YET, (As I'm not planning into overclocking or tweaking that much yet). Will buy later.
Case: ANTECK AKRON P-501 With a 500w PSU
RAM: 2 Kingston HYPER X FURY 8 gb. (16 gb in total)

Take into account that some of these specs you won't find them on places like PCpartPicker, (Such as the case, and I think the HDD, not sure on that one) because I bought all this with a contact that I have that has access to the companies that supply the retailers, in order to get all these stuff cheaper. Also, I think the case is only available in Mexico.
And for exaclty the same reason, I think he'll be able to get the PSU for me, at a reasonable price.
Rate my specs, btw. (But ignore the lack of optional features that I'll get later)

It's a great PC. Of course the parts you are planning on buying later will make it even greater. Your CPU is one of the best locked i5s and is priced well (thus a great choice for those on budget) and should be able to run anything. Your 960 is also a good mid range graphics card that can run games well on 1080p. 16gb ram will last you many years as games don't use more then 8gb at the moment. I found your case on google and if there was anything I would suggest, it would be possibly to add another fan or two to help keep the graphics card and your planned future upgrades cool, but thats an optional upgrade for later on, when you add your new cooler and SSD.

It's a fairly efficient PC that doesn't draw much power. A good 500w PSU will be enough for this system, though a 600w may be nice for the extra headroom. It depends on what your contact can find.

Carefull with 6 pinto molex connectors, the W is not enough and can fry the cable. 6 pin uses 75W molex very rarely can deliver without overheating, yes there are stories of melted cables messing up stuff. my advice, get a new PSU

Yeah I know, I'll be upgrading it very soon.
