I want to swap this card to my good old R9 390,but since this PSU is not modular,I don't know where to connect those 2 black wires?

I know I connect them 6+2 (2 are black wires) to 8-pin connector on GPU,but do I connect it to first pins on the left side or right side of the 8-pin connector?

It would be great if someone could just picture it.

Please do not take offence for my apparent confusion or rudeness,it's not intent me to be like that,it's just my BPD,be nice to me,and I'll return twice better,be rude and usually I get easly pissed of...I'll try to help anyone here,as long as it's something I dealt with,and even if you think I'm rude or not polite,forgive me,  it's not me it's my BPD.

Thanks for understanding.

6+2=8 (quick maff)

 

And you have 2x6 pins.

 

Quick maff you don't need those +2 to be plugged.

The +2-part of the connectors are always on the LEFT SIDE of the 6+2 connector. That`s why they have those two noses on the right side and the 6-pin has the fitting notches on the left side.

Anyways it should not fit any other way since the pins aren`t all shaped the same:

Yes I do,R9 390 Strix requires 8+6 pin.

So 2 black wires I plug to the left side of the 8-pin connector?

He wants to swap to another card with one or two 8pin-connectors and wanted to know if the +2 go left or right of the 6-pin ?

Oh that well what you said is the good answer then :P

You can't plug the connectors into a card the wrong way, because they're keyed... the holes have specific shape.

 

If your video card has a 6 pin connector, you just plug the 6 pin part into the video card and leave the 2 pin bit floating in the air, unused.

 

You can create a 8 pin connector out of the 6 pin part and the 2pin part by joining them together - sometimes there's some kind of channel / groove on the edge of the connectors, and you can slide in the 2 pin part into the 6 pin part (or the other way around), to lock the two parts together and make the 2 parts insert easier into the 8 pin connector of the video card.

ah ok,so basically it's impossible to plug in 6+2 connector to 8-pin on GPU the wrong way,except ofc to brute force it?

 

Please do not take offence for my apparent confusion or rudeness,it's not intent me to be like that,it's just my BPD,be nice to me,and I'll return twice better,be rude and usually I get easly pissed of...I'll try to help anyone here,as long as it's something I dealt with,and even if you think I'm rude or not polite,forgive me,  it's not me it's my BPD.

Yeah see picture below ... you have your square "pins" and your "D" "pins" ... you can't shove a square into a D shape unless you're drunk and abuse it.

I used  --  instead of D because my paint skills are not enough to make a nice D shape.

Oh ok.are those 2 black grounded pins?whats the purpose then connecting those 2 if they dont give more amps?

The original connector had 6 pins and the specifications said the video card must not take more than 75 watts from the power supply through that connector. The limitation was based on the thickness of the wires going to connector, each pin's current handling ability, redundancy and safety - you don't want connectors and cables to overheat due to too much power going through to the video card.

 

(AWG 18 wire can carry around 100-150w safely, without insulation of wire becoming too hot or melting. The individual metal pins in the connectors can do around 9-10A which at 12v means around 100w per pin, so 2 pins would allow up to 200w, but what if one pin was loose or user plugs the connector half way?... that's why for redundancy and safety they decided on 75w because even with only one pair of wires, it would be safe to use the video card)

 

Initially in the first specifications of the connector, the connector was one row of 12v and one row of ground wires, but in the 12v row, only 2 of 3 positions were supposed to be used for 12v wires, one position was either sense or just nothing connected there. However, majority of power supply manufacturers just decided to also use the 3rd position for 12v, even though the preliminary standards said otherwise. 

The 75w limitation were smartly chosen keeping in mind the only 2 wires carrying power, but power supply manufacturers used 3 wires making it even better (reduced strain on the 2 contacts and made power losses lower).

 

Later, they added those 2 ground wires as a way to "hint" the video card that it's allowed to take more than 75 watts from that connector, up to 150w (double the original standard),  guaranteeing there's 3 pairs of wires (not just 2 as the original standard said) and that the wires are thick enough and connectors good enough to handle 150 watts.

 

If the video card doesn't detect those 2 wires plugged in, it should not take more than 75 watts or refuse to start, saying it doesn't have enough power.

 

I suppose the idea was that someone may make a 250-300w power supply with thinner wires and only 6 pin connectors, to save cost on wiring and all that...

But I still dont get it,if the card requires 8-pin (more amps) how will it get via wires which are grounded?Hmmm ..

From the other wires of course.

As said this is only to tell the card that the PSU and wiring are able to supply 150W.

It doesn't get it through those 2 wires. Think of those 2 wires like a on/off switch, a flag, it just tells the video card "it's ok to suck up to 150w through the 3 pairs of wires on the 6 pin side of the connector"

If those 2 wires are not there, the video card is supposed to assume "there may be only 2 pairs of 12v wires on the 6pin connector part, so don't take more than 75w from connector. If you do. you're not allowed to advertise yourself as pci-e video card"

Ok guys.thx for info.I'll plug the card and test it becuase this PSU I have in that comp is I guess a crap..

Guys connector on 6-pin don't match,I noted with mumbers,I did plug them back but because of cable routing I unpluged them and found out that,look at the pic below:

1 doesn't match with 1,2 with 2 and so on...

Nope you are just looking at the way it should connect.Card in installed...1 should go to 1,2 to 2 but pins are not the same...

Look at plastic holder on the connector and I turned the connector on the cable to face the connector on the card.

 

Please do not take offence for my apparent confusion or rudeness,it's not intent me to be like that,it's just my BPD,be nice to me,and I'll return twice better,be rude and usually I get easly pissed of...I'll try to help anyone here,as long as it's something I dealt with,and even if you think I'm rude or not polite,forgive me,  it's not me it's my BPD.

It's called a 6pin connector because it only needs 6 pins.
