Will MSI GTX 750 TI TWIN FROZER work with my 500 watts Power supply?

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 :)

  1. Best answer
    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!
  2. Just for the record, what power supply do you have?
  3. 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.
  4. It will not explode because the Components pull their needed power from the PSU not the PSU pushing their power on their components!
  5. 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?
  6. That we do not know and only you can find out being able to see which fan is hitting what.
  7. 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.

    Try and answer all my questions please :P
  8. It should work.
  9. 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
  10. 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.
  11. This is it, I got the PC from this seller on ebay, but he also sells the parts separately. This is the link to the power supply which I have: http://www.ebay.co.uk/itm/ACE-PSU-500W-120mm-SILENT-FAN-Power-Supply-Unit-/321320212441?pt=UK_Computing_PowerSupplies_EH&hash=item4ad02d57d9
  12. It is not a good PSU and has the ratings of a 300watt unit not 500watt!
  13. 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!!!
  14. It will work for the 750 but suggest replacing the PSU first to quality budget unit, Corsair, Antec and EVGA have some.
  15. 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?
  16. The key is in the +12 volt amp rating yours has 18 amps here is a budget 500watt EVGA unit http://www.newegg.com/Product/Product.aspx?Item=N82E16817438012 It has 40amps.
    (not on steam!)
  17. 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
  18. Upgrading PSU is easy, unplug and replug in reversed order. I would chance the GTX750Ti since it will run but upgrade PSU as soon as possible.
    Good source on PSU quality http://www.realhardtechx.com/index_archivos/Page541.htm but really modern PSU's have over 80% of their available power on the + 12volts and quality ones 90%.
  19. 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..
  21. 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 :)
  22. 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.
  23. 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.
  24. You have a 650 already, so go for upgrading the power supply first. When I upgraded mine, I had lower temperatures than before and even a small boost in performance.
    The 750Ti consumes less power than the 650 anyway, so it can come later.
  25. Am I able to switch from the GTX 650 to GTX 750 Ti soon since I only got 650 less than a month ago and I can still get a refund from amazon and swap it for 750 ti since that costs more. Then I could upgrade PSU if that sounds good?

    It will work but as many here know the PSU is the most important part of the PC since all of the other components depend on it so do not leave it too long.
  27. Thanks very much for all the help!!!
  28. Also, something that I just wanted to ask, I sorta understand the amps now, but is there a specific way to tell for a certian type of graphics card? Since it doesn't state anywhere on the NVIDIA website about Amps. Are there any ways to know for specific graphics card how many amps they need? Sorry for so many questions, but I would like to full understand this. Also, how did you tell my PSU had the rating of a 300 watt PSU and not a 500 watt PSU?

    Thank you so much, all this info is helping me for the future :D
  29. No problem. Atleast you're asking.

    Here goes.

    Consider your system's CPU. It's a AMD FX-4100 which has a TDP of 95W. That means under full load, it's going to consume 95W if you don't overclock it. The CPU also takes power from the +12V rail, same as the GPU. Now power = current x voltage, so you get the current for your CPU as 8 A.(8 x 12 = 96)
    Now consider the GTX 650 graphics card. It also has a TDP, which is 64 W. Using the same formula, you get a current of 5.33 A. So your CPU and graphics card under full load are going to consume a total current of 13.33 A.

    Now, there are other components (such as fans, hard drives, optical drives) which run on this rail, as well as the motherboard itself. So around 5-7 A are reserved for them, as a buffer. So you get the amperage for your system as 20A or 240W on the +12V rail using the above formula.

    Now, all power supplies don't provide their rated power on the +12V rail, and cheaper ones provide very less than they should, as they're not designed for gaming computers with fast graphics cards. Your 500W is one of them, it's actually a 300W with a "500W" label slapped on it to increase sales(Liars, I know).

    If you go for a better power supply, the low-end ones still don't provide their full power on the +12V rail, but they come close to that. A proper 500W power supply will have around 400W or more power on the +12V rail, to give an amperage of 33A.

    A good 300W power supply will have more than 20A for actual power rating of 240W or more. You could run a 650 or 750Ti on such a power supply.
  30. Wow, that is a lot to take in. I sorta get it, but a few things I need to understand more are you said 95W at the start and then using the formula it turned out to be 96. Where those meant to be the same things? And is now power the watts? And how did you find out the TDP and Current and voltage and so on? And also you said the current is 8 A what does the A mean?

    I do understand most of it now anyway, thank you so much for the help!!! Now most of it makes sense to me. :)
  31. Watt is the unit of power, given after James Watt, a scientist.
    Just understand that when you're given voltage and current, you multiply them to get power.
    Power = voltage x current.
    I rounded the power to 96.

    A is amperes of current. A CPU that uses 95W of power uses current 95/12: 7.91 amperes, so if I round it, I get 8.

    You can find all data on the manufacturer's website, so in this case the CPU you can visit AMD.com and for the GTX650 graphics card, you can go to Geforce.com and search for 650.

    Just curious, how did you find out what your components were?
  32. On system propeties and I installed the GTX 650 myself. And I looked in the computer and found the info on my PC :)

    Thank you so much now I fully understand this and it will come in handy for the future :) I have even saved what you said in a notepad since it is so handy!!!
