Hey!
So the reason only 3 of the wires are used is because graphics cards only take in 12v.
The pins of a molex are +5v (red), Ground, Ground, +12v (Yellow).
So only the 12v and ground wires are used.

As for the adaptors, I would choose the first one. It uses two molex plugs to one 6pin. This means less power will go through each molex plug, meaning they will not get hot.
The problem with molex plugs is they were not designed for very high power, so they can get warm under heavy load.
So the dual molex to 6 pin will be better as the power is spread across two connectors.

If your PSU does not have the connectors built in, its not properly made to handle a GPU. a 6 pin connector can deliver up to 75w, thats not a small amount of power.

You should consider replacing your PSU with a good quality one. Adapters are always a bad idea.

is this another molex? Just wanna be sure

 


I agree with this, the type of PSU that does not come with a 6+2 connector is a low end unit not up to the job. If it dies you risk it taking you whole pc with it. Get a decent psu designed for your needs.
 


Well my previous card required ~65W and now i disconnected my dvd drive just so im able to get the new card running without a problem so it should work right?
 


Just because it works doesn't mean it won't fail thats the problem. DVD drives use very little wattage compared to a GPU.

Chances are it will "work" fine, the question is how long (probably not very) and how much damage will the PSU do when it fails.

Whats all your system specs (brand and models) especially the GPU and PSU?
 
STOP, DO NOT USE A MOLEX ADPATER, you need to listen to Rouge Leader's advice

If the PSU does not have the proper connections for your GPU then it was not designed to handle the load.
It does not matter what the sticker says for the wattage as the sticker is exactly that, a piece of paper with ink printed on it.
Best case scenario you have a good PSU (like an OEM dell one) that just does not have the wattage to support a higher powered graphics card.
More likley scenario you have a cheapo unit that cant ACTUALLY sustain outputting half the load. Not only do these units fail to support the claimed wattage, they also cheaped out and did not put any saftey circuitry in, thus when they die (when and not if) they fry the rest of your computer parts as well (usually the GPU and motherboard).
 


New gpu is gtx 1050ti OC PNY with 2 fans
Psu spire ATX 420W-PFC-N-PSU
motherboard ASrock h81m-dgs
RAM balistix 2x4GB

Anything else needed?
 
Adapters are not evil, just misused.

One molex to 6-pin. Bad idea. Two molex to 6-pin. OK. The two yellow 12v wires (unless a very cheap PSU with 22-ga wires) can easily provide more than the 75w required. In fact, many cards are shipped with 2 molex to 6-pin adapters.
 


What exactly do those 22-ga wires mean? Can i check that myself or could you look at my psu model and tell me ?
 
Size of the wires. Larger number means smaller size, and less current carrying capacity. Should be printed on the wire itself - "18 awg" for instance. 18 gauge which is most common for PSU. May need a magnifying glass to read as the print will be small.

That said, a PSU with the proper connectors is always best. But using an adapter correctly does not always mean disaster.

 
Well I realise I definitely should have said to check your power supply!
However... AWG is American Wire Gauge, a way to measure thickness of the wire.
The smaller the number, the thicker the wire. A cheap power supply will have 20 to 22 AWG, which is thin and cannot handle a lot of current without getting hot and burning the insulation and starting a fire.
18AWG is a good place to be, and what good PSUs often use. It does not sound like much of an increase but remember that when a circle radius doubles, area increases four times over. So 18AWG can take a lot more current.
 




So am i getting an adapter or a psu?
 
Like everyone has pointed out, unless you are sure your PSU can supply enough power, it is a much better to get a new PSU that comes with 6 pin power cables for graphics cards.
This may make a dent in your pocket, and depending on the wattage you need, should cost somewhere between £50 and £80.
Consider it an investment for the future - getting a good power supply now means you do not have to worry about it failing and also means you can further upgrade your PC easily.

I recommend that, if possible, try and go for a new PSU.
A few good brands include Corsair, Seasonic, EVGA, Supler Flower, and ThermalTake.
 



Is this one ok then? https://www.amazon.de/gp/aw/d/B00LMBWSI8/ref=mp_s_a_1_3?__mk_de_DE=ÅMÅZÕÑ&qid=1486062786&sr=8-3&pi=AC_SX236_SY340_QL65&keywords=corsair+psu&dpPl=1&dpID=51l7DjgF89L&ref=plSrch
 


Yeah that PSU is 100% fire hazard. Do NOT use an adaptor with it.

There you go, good quality PSU in your budget.



Don't buy that one its junk compared to the newer model I linked above.
 


I'm sorry, Did you not see the PSU you asked me to link?
