Windows 7: Thinking of getting a new gpu , some advice needed

Thinking of getting a new gpu , some advice needed

Hi guys,

I am looking at getting a new gpu in the next couple of weeks , still not decided on exactly which one to go for , but I could do with some advice on power connectors.

The gpu I am looking at as an example is the Point Of View GTX260 896MB DDR3
Point Of View GTX260 896MB DDR3 Dual DVI Out PhysX and Cuda ready PCI-E Graphics Card - Ebuyer

Now it states in the description - "Supplemental power connector 2x PCI-E 6-pins"

So I assume it comes with these 2 cables.

Now to the bit I am unsure of so bear with me, I assume the 2 x PCI-E 6-pins connect to the back of the card itself , and at the other end of each one is female molex connector which in turn connects to the male molex coming from the psu.

Is there 1 or 2 female molex connectors on the end of each of PCI-E 6-pin?
In other words do I need 2 or 4 free male molex connectors?

And also I am having difficulty in finding out what sort of power supply this card needs.

Sorry for all the novice questions , but to date the best card I have had is only an old 8600gt and now I have a new pc I would like something a bit better but need to make sure I get the right thing.

Thanks

Paul.

The 2 x PCI-E 6-pin connectors are standard connectors on modern power supplies. You can get power supplies with 2, 4, or 6 PCI-E connectors. These connectors supply the card with three 12v circuits. Each PCI Express 6-pin connector can usually output a maximum of 75 W.

Your GTX260 will not come with any cables or adapters unless it says so in the specs. You might need to supply those separately. You can buy Molex to PCI-e adapters.

A molex connector has only one 12v circuit, so the adapter splits that into 3. This is not very efficient and there could be variations in the signal from the supply.

These high end cards are very touchy and Windows 7 is very demanding of video. My best advice is to upgrade your power supply also. Look at a minimum 650w or better from well respected brands. There are lots of people having problems getting a stable system with cheap power supplies.

Hope that helps.
