Pozdravljeni!

Ker sem na kratkem z časom in ker sem že en čas izven teh vod, bi prosil, če ima kdo voljo sestavit comp za 1000 - 1100 eur z vključenim ekranom. tipkovnica, miska nista potrebna, pravtako lahko uporabim staro ohisje (Antec).
Hvala, Lp

Mal več bo potrebno povedati, namen uporabe, se lahko naroča v tujini...?

pa me sam zanima ce so to enokanalni RAMI?

Question regarding the PCI-E graphics card accessory power cables. The 6 pin PCI-E cable has 3 12V lines (yellow) and 3 ground return lines (black) and is rated for an additional 75 watts of power for the card.

However, the 8 pin PCI-E cable has 3 12V lines and 5 ground return lines (black). No more 12V lines, just 2 additional black gnd lines

Johnny & the group,

Have learned several interesting facts about the PCI-E plugs and power after researching it this past week, that is worth sharing

The PCI-E connecter has 6 pins. They are not all used for power. For the 6 pin connector, Pins 1 & 3 are 12V & each can carry 8 Amps. Pin 2 by spec is not connected, although some PSU manufacturers do add a 12V line there. Pins 4 & 6 are Com return lines. Pin5 is Com for sensing. Using 2 lines, you get 12V*8A*2= 192Watts, much over the required 75Watts. With an 8 pin PCI-E connector, 2 Com lines are added (4&8) not a 12V & Com. There, Pins 1,2,3 are 12V, Pin 4 is a Com for the 8 pin connector sensing, Pin 5,7,8 are Com return lines, & pin 6 is for the 6 pin connector sensing. Using that config, 12V*8Amp*3=288 Watts, much over the required 150Watts.

Since Mar 2005, the molex pins are required to be "HCS" rather than "Std", which each carry a max of 11Amps. So properly made, an 8 pin PCI-e can supply 12V*11Amps*3lines=396Watts of power for the graphic cards.

Ther aren't 4 12V pins on the 8 pin connector, only 3, and 2 leads are used for sensing the connector type.

The other limiting factor of course is the width of the PCB lines on the graphics card, each typically carrying 1-2 Amps. That would also determine how much power it could carry to the graphics electronics.
Also worth noting Scott Meuller in his latest 19th Ed of "Upgrading and Repairing PCs" has this information incorrectly listed.

Kakšen napajalnik maš?

na voljo je LC 6550; po potrebi bi ga lahko tudi menjal (oz. ne če ni nujno).
