Molex used for fans? Are they usable for Graphics Card?

Hi, I was looking at getting a GTX 960 and was going to use adapters from my 2 molex's to get to an 8 pin. I was looking at my molexs and noticed there were wires coming out of nearly all of them to power the fans. Are they not usable or are they not molexs at all. (they are black) I am a beginner and would really appreciate a quick response.

The above should come to the same as the FX6300+GTX750Ti and will give a bigger boost but I'm guessing the current CPU is a FX quad or similar, in which case you won't see a big improvement in most games by jumping up to the 6 core part, an improvement yes, but not as big as the R9 270X will provide.
The above is an alternative suggestion, you can drop in a FX6300 or even an 8 core 83xx later on when funds permit, the motherboard will handle it and the R9 270X is a decent 1080 card, much stronger than a GTX750Ti...

What GTX 960 needs an 8pin? The 960 is a 6 pin specification card and should run with a 6pin into 8pin adapter. I ran my MSI 970 with 2 6 pin connectors when it had 6 and 8 pin holes before I upgraded my PSU.

Unless you're running extreme overclocking, your cards should run using the Nvidia specified power connectors.

If you don't have the fan cables plugged in they shouldn't be a problem. Even if you do, fans aren't super huge power drains typically.

It has an 8 pin, but only has a listed power draw of 120 watts. Fill up the connection, but I would suggest getting a different model that does not need an 8 pin. EVGA's short length 960 only needs a 6 pin, as do many other brand's 960 cards.
 
@ thelynx: Exactly which power supply is installed?
It would be simpler just to get the 6 pin EVGA card, unless you intend to overclock the card to a nearly suicidal maximum there's no need for an 8 pin hook up.
If the installed power supply has NO PCI-E leads it's not suitable for the GTX960 anyway, either it's very old, based on a very old design or the output is too low.

Thanks guys, I will get the 6 pin model. Also are the black 4 pin connectors molex's or not, they have fan wires coming out the top? Is there any way I can send you a pic?
 
Molex actually covers several types of connector, this is the large, 4 pin type, it's about the same width as a SATA connector but thicker: http://www.bing.com/images/search?q=molex+plug&view=detailv2&&&id=295BE49039A3B396962DB68AD0F5CB06B073EC1B&selectedIndex=21&ccid=vS5JAhMV&simid=608016556235229848&thid=JN.b73tCAlXmDFs8q2%2fJzOUSw&ajaxhist=0
There is some slight variation in design, some are white, some black but they all have 4 quite thick wires and 4 pins, it's not usually a good idea to use them for a graphics card, although a pair can handle the current needed by a GTX960 if the installed PSU has no PCI-E leads it's either very old or has a very low output, making it unsuitable.
Please post the make, model and output of the current unit, overloading a power supply can cause it to fail, and cheap units have been known to fry other parts when they go.

What I just want to make sure is this, I have a 500w psu, I have a M5A78L-M motherboard, an FX-4350, 1tb HDD and 8gb of ram. I want to make sure I can install an FX-6300 and a GTX 960, using two molex's into a 6 pin adapter for the graphics card. I just want to be reassured that it is possible for me to do.
 
According to this list: https://www.asus.com/Motherboards/M5A78LMUSB3/HelpDesk_CPU/ the upgraded CPU is a fairly direct job, although you may need to update the BIOS beforehand.
No, the current PSU isn't up to the job, the fact it has no PCI-E leads at all is a big red light, it should be changed for something suitable or you risk it failing and, considering the make, damaging the rest of the system.
Any decent 500Watt unit from: Corsair (try to avoid the GS, CX and VS Series), Silverstone, Seasonic, Antec, Superflower, FSP (Aurium Series), Rosewill (Capstone Series), XFX (Pro Series) or BeQuiet (Dark Power Series) will do the job.

Thanks so much guys. I can't upgrade my psu at least at the moment, so, my final question is does anyone know a good graphics card for 1080p titles at medium to high or even very high/ultra that would be ok with my system? Thanks.
 
The most powerful card currently available that doesn't need a power lead is the GTX750Ti (be careful a few do need that lead), it's a decent performer at 1080 rez but some way short of the GTX960: http://www.guru3d.com/articles-pages/asus-radeon-r7-370-strix-review,1.html some of the benchmarks in this review compare the GTX750Ti with the GTX960.
Sounds like you're on a very tight budget but try to avoid getting a lesser card, you'll only regret it later on when you upgrade the CPU only to find the graphics card is holding back the system.
We're getting well away from your current question, though (which I now guess has been answered) so I suggest you start another thread asking for help with the upgrades, you'll get more readers and a wider selection of advice by doing so.
Post with: Full, current specs (including monitor resolution), intended upgrades (including the PSU), budget and timeframe.

To start the ball rolling I'd: Replace the PSU first, it's a weak part right now and is the bedrock the system should be built on, if you don't plan on overclocking 450Watts will be enough, 500Watts for overclocking.
Graphics card next, you haven't supplied details of the current card but you'll usually see the biggest jump in gaming performance here.
CPU last.

Thanks, I don't really have enough to get a new psu and i'm not sure i'll be able to reconfigure all the cables as i'm interested, but have never built/upgraded a pc before. What I think I am going to do is get an FX-6300 and a GTX 750ti, as I think that is close to the maximum my PC can take at the moment. Yes, I haven't said what my current graphics card is, it's a really awful R7 240 and I can't to much on the card especially on 1080p. Thanks so much for your help, and if you have any concerns about what I am going to do with the CPU and GPU, please let me know, other than that I think I am close to getting a new PC, and probably building it. The 750ti seems like the best option.

Or you can go with the FX6300/GTX750Ti now rather than having to wait for the CPU upgrade, your choice.
