Hello, I plan to mount the following set graphics card Sapphire Radeon HD 7870 XT With Boost (11199-20-20G) : 1. MSI B250M PRO-VH motherboard; 2. Intel Pentium G4560 processor, 3.5GHz, 3MB; 3. GoodRam DDR4 PLAY memory 2 x 8GB, 2400MHz, CL15 RED (GYR2400D464L15S / 8G); 4. XFX Core PRO 450W power...

Depends on what outputs you have on the power supply. It will be best to connect each power supply on a separate line, which is why the manufacturer gave two adapters - assuming that someone will not have 6pin, only molexes.

So it's best to connect this one 1x6pin line from the power supply and the other to make from a 6-pin molex adapter?

The power supply has one 12V line and thick cables. It also has a lot of molexes, so I would connect it to 2x MOLEX -> 6 pin selecting molex plugs on two separate beams. Use the other plug without any modifications straight from the power supply.

Thanks for the answers. So @ dt1 you say it's better to give a 2molex - 6pin adapter for this?

Yes, I would use it with a power supply with enough molexes.

Like the manufacturer attached to this card two adapters: 1molex - 1 connector 6 pin.

Theoretically, the load capacity of the molex plug is 11A per line, i.e. ~ 130W. Given that the card is still powered by a direct cable from the power supply, an additional cable from a single molex can also handle it.

And what would the hypothetical load capacity look like if I used such an adapter: 1x6pin to 2x6pin:

The theoretical load capacity of PEG 6pin is 75W, PEG 8pin is 150W, in practice certainly much more (since Molex can handle over 130W on one wire, and in PEG we have three 12V wires). Especially on a decent power supply with cables, but in which there is more metal than insulation, there should be no problems.

The graphics card Sapphire Radeon HD 7870 XT With Boost (11199-20-20G) needs 185W, so it's better not to risk with a 1x6pin to 2x6pin adapter:

Hello, I plan to mount the following set graphics card Sapphire Radeon HD 7870 XT With Boost (11199-20-20G) :

1. MSI B250M PRO-VH motherboard;
2. Intel Pentium G4560 processor, 3.5GHz, 3MB;
3. GoodRam DDR4 PLAY memory 2 x 8GB, 2400MHz, CL15 RED (GYR2400D464L15S / 8G);
4. XFX Core PRO 450W power supply (P1-450S-X2B9);
5. Blue SATA III 7200RPM 500 GB hard drive, WD5000AAKX;
6. DVD drive.

The XFX Core PRO 450W power supply (P1-450S-X2B9) has a 1x6 pin power supply, while the graphics card needs 2x6pin power supply.

My question is what better adapter to use:

1.1 molex for 6pin

2.1x6pin to 2x6 pin

The rating plate of the power supply looks like this:

The manufacturer added two 1 molex to 6 pin adapters to the card.

Depends on what outputs you have on the power supply. It will be best to connect each power supply on a separate "line", which is why the manufacturer gave two adapters - assuming that someone will not have 6pin, only molexes.

For my it will do, but considering that the power supply has a lot of molexes, and a 2x molex-> peg grommet for pennies can be bought or sometimes even free. On the other hand, the plug from the power supply plus a grommet from a single molex, if you already have one, it is also enough.

Topic summary

The discussion revolves around the power supply requirements for the Sapphire Radeon HD 7870 XT graphics card, which necessitates a 2x6 pin power connection. The user is considering two adapter options: a 1x6 pin to 2x6 pin adapter and a 2x Molex to 6 pin adapter. Responses suggest that using the 2x Molex to 6 pin adapter is preferable due to the power supply's ample Molex connectors and the need to distribute the load across separate lines. The graphics card requires 185W, making it risky to rely solely on a single 1x6 pin to 2x6 pin adapter. The consensus emphasizes the importance of using multiple power sources to ensure stability and adequate power delivery.
