Red LED Geforce GTX 280

Today I got my XFX GeForce 280 GTX. They have connected (yes Mesopotamia has connections, 1x6Pin and 1x8Pin), but I have only two ports on NT with 2x6Pin for PCIe. So times have tried.

However, the computer does not start, the red LED lights on the cpu glows.

What does this mean? It must necessarily be 1x6Pin and 1x8Pin? They get enough power or is it broken? If I have a new NT?

Thank you for an answer

The new Tough Power 700 Watt power supply from Thermaltake has an internal temperature 140mm fan comes with a cable management to remove unnecessary cables and reached a very high efficiency. Four separate 12-volt lines with a total of 56 amps ensure a safe and low-noise supply of sensitive PC components. The power connectors are designed for all the Boards of ATX and EPS are suitable and two PCI Express graphics cards and up to 15 drives with power supply can.


Specifications:

Model: W0106
Power: 700 Watts
Efficiency: 85%
+3.3 V = 30 A
+5 V = 28 A
+12 V1 = 18 A
+12 V2 = 18 A
+12 V3 = 18 A
+12 V4 = 18 A
+12 V A = 56
-12V = 0.8 A
+5 VSB = 3.0 A


Connections:

7x 5.25 "
1x 3.5 "
6x Serial ATA
2x PCIe
1x ATX (20 +4- pin)
1x EPS (24-pin)
1x ATX12V (4-pin)
1x ATX12V (8-pin)

You must necessarily have 8xPin port, usually located in an adapter.

6Pin is only one adapter...something like shown here,

The GTX 280 has a TDP of 236 watts, two 6-pin connector plus the PCIe slot on specification but may only deliver 225 watts. With an 8-pin connector and a 6-pin plugs are allowed 300 watts. That is why the 8-pin connector required. Your power supply is sufficient, however.

You require a cable like this,

The immensely relieved me :) Thank you very much.

So I'm really quite sure: this is what I need.
