I live in India and am planning to buy the Nvidia GTX 760 for my PC.
Following are the specs;

  • CPU: Intel i5 3470
    Motherboard: Foxconn 17A0
    RAM: 8GB DDR3 1333Mhz
    PSU: Corsair VS550 550W
I have upgraded its PSU and the RAM afterwards.
Will the GPU fit and work perfectly with my PC? I've heard that my PSU might not be able to handle it.
Below are the links;

My PC

1st option for GPU

2nd option for GPU

Also which GPU of the 2 will be better if both of them are compatible with my PC?

Thanks in advance!!!:)

Your power supply is more than capable enough to power the GTX 760. The 760 requires 30 amps on the 12v rail, and the Corsair VS550 has 42 amps on the 12v rail. However, I am not sure your case is big enough. Your case is wide enough to hold the either of the two 760's you chose (there is enough height clearance). What you need to is measure the length of the space over your PCIe 16x slot. If there is at least 9.7 inches of clearance front to back where the GPU goes, then the 760 will fit.

Also, I would recommend buying a new case if you are going to upgrade to a 760, because the 760 produces quite a bit of heat, and that case isn't very airflow optimized. It's never a good idea to have the temps really high in your PC.

Good luck!

But I've heard that blower fans dont spread the heat in the case and simply force it out of the cabinet without heating other components.

The whole point of having fans in a case is to try to achieve more air intake than exhaust. If you have 3 exhaust ans on your case, then you want to try to have 4 intake fans, so that cool air comes in faster than the hot air leaves. This will keep the ambient temperatures in your computer low, and will help cool the CPU. When the 760 is cooled more effectively, the boost clock turns on, automatically making it run faster as long as it's cool enough to do so.

EDIT: Also, the Zotac GPU will preform slightly better than the Galaxy one, it has higher lock rates.

You don't get my point. As you've said earlier that the 760 will cause higher temperatures in my case, I'm asking wont the blower style fan on the GPU be able keep it cool enough?? I've read that blower fans are meant for mATX build as in my case they keep temperatures low in smaller cabinets with poor airflow.
Also I wanted to mention that there's just 1 exhaust fan in my cabinet and no intake fans. It didn't come with any intake fans installed from the factory. Is that normal??

Thanks for your quick replies!!:)

Ajitesh,

Yes, the fans that are included on the 760 will be able to keep it cool enough to run, but there will be a lot of ambient heat in your case. Like I said, the boos clock operates to make it faster only when the GPU is cool enough. You could run it in that case. Make sure you measure your expansion bay like I said to see if the 760 will actually fit in your case.

Also, a lot of mATX cases don't come with any intake fans, as they are meant for lower caliber builds. Putting a 760 in the case you have would be quite ambitious.

Wil the GTX 660 fit and run cool in my PC then if I'm not able to run the 760 or will that have heat problems too??

You will be able to run the 760 in your case now, as long as it fits. DID YOU MEASURE IT YET? The 760 will run but the increased temps in there will make the graphics card have a shortened life span. The 660 will be a lot cooler, and is still a very nice card.

Like I said before, you need to measure the case and see if there is at least 10 inches of clearance, you won'y be able to fit a GTX 760. The GTX 660 is the same size as the 760. If you're worried about heat, buy a couple of fans to get some airflow in the case.

I know I'm troubling you but sorry as it's my very first time upgrading. I tried to measure it and it's around 26cm(10.2 inches) but I'm not sure with what I've measured. What I've measured goes beyond the motherboard. Do I measure till where the motherboard ends or can I go beyond that?
Thanks a lot for your help.

Measure space above the PCI-E Slot of the motherboard from the back end on the case until something blocks you. Keep in mind that average and above that GPUs block 2 slots on the motherboard and on the back plate of the case. Also the motherboard must be "clean" through the whole length of high components. HP 3330's chipset seems to be in line of the second pcie slot (this is the small pci-e x1 slot on the motherboard) but I can not see what is the chipset radiator's height. If it is too high - you may not add a 2 slot video cards.
If not sure what to measure - try to find a friend with some experience. For this case/system 660 is more suited. If it fits inside.

You've measured correctly, and the GTX 760 will in fact fit in your case. I'd recommend that you purchase the Zotac one because it's slightly more powerful. Also, check to see if you can put any additional fans in your case, this will help with the heat the 760 will produce. The 760 can run in temps up to 100 degrees Celsius, but it's not particularly good for it. I don't think it will reach that temperature though.

And don't be sorry about anything. I only used caps because it was important, and I forget sometimes how words in all caps are interpreted on the internet. My bad!

If you have any more questions, just ask.

How do I check if I can fit another fan? I can't see any open spaces where I can fit one.

The blower type of fan in a graphic can does INDEED cool better than a normal one in a Matx case as due to the high airflow the blower type will be your best bet but if not no harm done and even if you get the non blower one you will still get a good 5-8 years out of the graphic card if you don't overclock it so it doesn't really matters to be honest with you.You will get a increase of maybe 5-6* C on the graphic card but that's about it and it usually runs at aroudn 60* C non overclocked and the safe limit is 80C thats when it starts to get its lifespan shorten by alot and trust me I live in india too and those are my temperatures of my graphic card non overclocked.

I bought the GTX 760 and installed it. Its working great but i see a temperature of 91C on Speedfan. It labelled TMPIN1 and on google it says it is the Southbridge temperature which is right under the GPU. My motherboard has no heatsink installed over it. Is it normal???
What should i do now??
