Will my PSU be enough?

[Deders]

Are they not all 6-pins?

 

[Optimus18]

yes indeed. but the problem I have now is that my grafics power cable (the one I have connected to my GTX 260 at this moment) has a direct connection from the psu to my grafics card (6 pin on the end) and I need this power source don't I? so how can I connect this 6 pin cable to my new r9 (which needs two molexes that cannot be connected because I only have a 6 pin cable)?

Re-read the explanations given to you in this thread.

Do you mean this?:

I would also start out by putting the 6 pin in the socket that is towards the back of the case, i.e. not on the very end of the card

I don't understand how this helps. Do I have to plug in my 6 pin connector cable which comes directly from my PSU into one of the sockets of my R9 270X card without using the two molex adapters or would that short-circuit my computer?


*edit*
Also I don't understand "towards the back of the case". does that mean I have a different 6 pin socket somewhere?

Not only that. The whole thread.

Already explained in this thread.

You plan to buy a graphics card with two PCI-E connectors (two receptacles for the PCI-E connectors from the power supply). One is closer to the back of the computer case (when the card is installed).

Ahh now I see the problem, sorry not been able to get back to you in a while, It appears this PSU is a Delta design without any Molex connectors as standard?

Although you seem to have an adapter to add Molex connectors?

Are all the Sata power connectors on the same strand?

If not you could buy another adapter that you could attach to a different strand from the first so you would have 2 strands to draw power to the additional 6 pin.

yes I think so! I don't know how you call these but you see those in this picture:

Although you seem to have an adapter to add Molex connectors?

yes one adapter can be seen here:

Are all the Sata power connectors on the same strand?

Yes unfortunately. But there is this thing here where a second adapter like this could be attached:

Isn't this the solution?:


Power source to the new grafics card number 1: The cable from the PSU goes directly to the R9 270X card (6 pin).

power source to the new grafics card number 2: the 12v Molex to 12V 6Pin adapter connects to two moles from different strands.

 

[Deders]

Those all look like sata power plugs to me, unfortunately if they are all on the same lead coming from your psu, then no matter how many adapters you have you will still risk heating up the single strand with all the sata connectors on it.

It may be easiest just to go for the most powerful card you can with a single PCIe connector, but depending on the load distribution it is very likely one of the 6 Pin sockets will draw a lot less than the other.

If you have already ordered the 2x6pin card then you may be able to return it, or if you are prepared to take the risk you should definitely monitor how hot the wires get by touch when the card is stressed or gaming. If you feel the main Sata strand wires are getting too hot then swap the 6pin plugs around and see if it makes a difference.

In my case it was the 6 pin socket closest to the the rear of the case (furthest from the end of the card, I know they are right next to each other) that pulled the most current, but as you can see from the french charts I showed you, different cards will demand different loads from each point.

If all else fails and you are determined to have the 270, then you may want to invest in a modern PSU that has 2x 6 pin connectors by default.

Only 1 PCI-E and zero Molex connectors on the existing power supply => buy a proper power supply if yo want to use a graphics card with 2 PCI-E connectors.

I will get this one then::

http://www.newegg.com/Product/Produc...82E16814127699

it requires only one power connector. gotta find out the max wat usage and then I order it..


*edit*

actually no, I got with this:

http://www.evga.com/products/product.aspx?pn=02g-p4-2662-kr


EVGA GeForce GTX 660 Superclocked



awesome card. and on this one I can just plug in my 6 pin to psu connector? not the 6 pin to molex?

Each connection can supply up to 75W, so PCIe slot + 1x 6 pin connector means the maximum it should draw is 150W. an 8 pin connector could supply 150W by itself.

The 660 draws 140W max according to Nvidia.

It may be worth searching to see if any 660TI models come with only one PCIe slot as it is more powerful and only draws 150W (again according to Nvidia). Most I expect will come with 2 though but there may be exceptions.

*edit* that EVGA Superclocked does seem like a good option.

 

[Optimus18]

Thank you for the feedback. I also think the EVGA option is very good. I only see 90+ ratings and really good feedback

Not quite... capacitor aging is a well known phenomenon, it decreases the capacity of the capacitor, thus decreasing the overall capacity of the unit. Higher quality caps are less prone to aging

Yep just as a kind of a sidenote agreed. The numbers vary but usually you need headroom of atleast 10% for year one and then a dramatically lower number (percentage) each consequetive years of degradation. Still it needs to be calculated and there are a number of diagrams out there depending on the cap quality yes. 🙂

Really good to know, thanks!
