Hey guys, this is my first ever question on this site. Will MSI GTX 750 TI TWIN FROZER work with my 500 watts Power supply? I am wondering since right now I am using a GTX 650 and its working fine. I got told something about it is recommended that I upgrade it so i don't run into any trouble, but when I checked on the NVIDIA website it says that 300 watts minimum. A person told me its not all about the watts and it's also about the Amps. Then he sent me a link to a 850 watt power supply and said that would work better with it. I don't know if he is just trying to make money from me or if I can run it just fine. He said it will probably just blow. I don't really know much about amps, and I just looked on the NVIDIA website and for the requirements for MSI GTX 750 Ti TWIN FROZER and it says that I need at least 300 watts and I have over that. These are my specifications:

Processor: AMD FX-4100 Quad Core Processor
RAM: 16GB
Graphics card: ASUS GTX 650
Power supply: 500 Watts
Motherboard: MS-7641

Please answer and feel free to ask any questions. If I have missed any information you need just say. Needs to be answers as soon as possible since I want to swap my old graphics care which I only ordered a month ago for the GTX 750 TI if it is possible. Thanks for any answers :)

Thanks in advance :)

Yes it will work fine the only size limit is minimum has to be 300 watts, there is no max size and it will work fine with any PSU bigger than 300watts!

Ok, thanks, so you are sure it will work fine and it wont explode like the guy said? Or do you think he is just trying to make me buy stuff so he can make money?

And I don't know which Power supply it is.

Also, does anyone know what that really loud clanking noise is in my PC? It's getting really annoying and it doesn't sound like a fan.

Ok, so it will defiantly work fine without any problems? Also, I am sure this graphics card I have now is getting slightly slower even though I have only had it for 1 month.

And also what is that loud clanking noise?

Ok, thanks you very much, but the guy also said it's not all about the Watts and its about amps. Does that matter or what? Or is the only requirment for it 300 watt PSU? And also my graphics card seems to be getting slower, do you know why and how could I stop that from happening to the new one. Also the GTX 750 TI is better than GTX 650 right?

Thanks

That's why I asked what power supply you had. There's always a sticker on the power supply. Can you take a picture of it and post here? You'll have to open the case cover for that.
Graphics cards don't get slower, just obsolete.
The 650 requires 64W of power, and the 750Ti requires 60W. And yes, the 750Ti is way faster than the 650.

OMG really? What do you think I should do? Do you think I should just stick with the GTX 650 and upgrade the PSU first? Is it safe to have the GTX 650 in my PC now? Also, I am only 13 so I don't really know what I am doing. Please could you tell me what I am looking for for a good power supply and how to tell if it is a good or bad one? And what I should do?

Thanks!!!

Ok, I will get the graphics card then I will try to get a new power supply. Are you on steam because if so, I would like to add you so I can ask you questions since you seem to know a lot :) Also, how do I tell if it is a good or bad ones since you said that has the ratings of a 300 watt not 500 watt although it says 500 watts. How can you tell if it is worse than it says?

Thanks for telling me all this. I want to be an IT Technician when I am older and I need to learn all this. Also how can I tell how many amps is good and how many is bad? Should I upgrade to the GTX 750 Ti and would it be safe? I will upgrade the PSU eventually but is it easy or hard? All I have done is change a graphics card.

Please answer all questions :D

Ok, thanks I have got a list of the minimum amps and watts for graphics cards. The GTX 650 and GTX 750 ti are both 300 watts and 20 amps. My PSU is 500 watts and 18 amps so it is under the minimum amps. It should be able to run ok, but I will upgrade to GTX 750 TI but will try to upgrade PSU asap. I also only have PCI Express 2.0 so I am running a lower version. Will that make a difference or not?

Thanks again

Those number have a safety factor in them and if your PSU was not enough it would simply crash or shut down the computer. The PCIe version will not affect the performance and is fully compatible across versions..

Is there a way to tell how many amps is good for you pc and how many isn't so good? I know more is better but is there a way to tell and a minimum for a graphics card? I will probably upgrade to this one: http://www.amazon.co.uk/Corsair-Builder-Series-Modular-Certified/dp/B00ALYOTTI/ref=sr_1_5?ie=UTF8&qid=1397929991&sr=8-5&keywords=power+supply#productDetails

Also, I think I might need to upgrade my case someone since It is a midi case and to fit big graphics cards you need a big case. Would it be easy to transfer all the parts from 1 case to another?

Thanks :)

There are a few components that require power from the +12V rails, so it doesn't depend solely on the card.
However we can loosely say this:
Generally for a PC without a graphics card, a 250W power supply with 16 or so amperes of current is enough.
A low level graphics card(such as the Geforce GTX 750, or the AMD Radeon HD7750) would need atleast 300-350 W of power and 20-25 Amps of current.
Mid end graphics cards(like the GTX 660) can go for 450W and 30-35A.
High end graphics cards(like the GTX 770 or the GTX 780Ti) would top out at around 45A and 600W of power.

For people who go for more than one high end cards, they go for 800W and above power supplies with more than 60A of current.

It is expected that, as rolli59 said, 80% of a power supply's power must be in the +12V rail atleast, i.e for a 450W unit, atleast 30A or 360W.

It's easy to upgrade the computer case if all parts are fitting and the case is big enough. If say, the graphics card is too big, then you'd need to remove something which could make things complicated.

Yea, ok, thanks. So what I probably will do is upgrade the graphics card to GTX 750 TI. I am just making sure, will it definatly be safe to switch to the GTX 750 Ti and then I will try to upgrade the PSU soon after. Eventually I will change the case, and so on. I will slowy upgrade it.
