300W Power Supply Enough for EVGA GeForce GTX 750 Ti Superclocked 2GB?

Hello all, I have an off-the-shelf computer and I was wondering if my power supply was enough to handle it without an upgrade. My exact computer is a Gateway DX4320-01E. Here is a link:

Lots of people are saying it requires a minimum of a 400W PSU but it says right on NVIDIA's and EVGA's website that it only requires 300W and that has me really confused. Thanks in advance!

    The 750 and 750 Ti are made for upgrading OEM built systems like that. With your system and a 750 Ti, you're looking at around 150w for gaming, and will most likely never top 175w.

    http://www.anandtech.com/show/7764/the-nvidia-geforce-gtx-750-ti-and-gtx-750-review-maxwell/22

    Anandtech uses an overclocked i7 Extreme, so take off around 25w or so for your system.

    300w is plenty :) just make sure your power supply has a PCIe lead if the particular 750 Ti you're looking at has a plug for it.
  2. the total wattage can be under 300W, but you should leave some wattage since the efficiency on the PSU is never 100%.
    if your PSU is 300W then it leaves little space for error and the lifespan of the PSU will decrease since it's running at max.
    You wouldn't run your CPU at max, in the same way It's best to get a PSU which is higher wattage then you need.
    + PSU is a component which can be recycled for future builds

    Wow, fast response! Thanks so much! I feel alot better now, but I'm going to wait and see if anyone else agrees with you. I already have another response as well but he seems skeptical that it will work.

    His build will run about 50% of the PSU, definitely nowhere near max, and puts a full system load at the peak efficiency rating for the power supply.
  5. I just checked the specs again total usage is below 200W
    cpu 125W
    GPU 60W won't have problems running these specs with 300w psu. But it's a little worrying that they never put up complete spec's (which make is the PSU/mobo/RAM?) and like I said no room for improvement.
    I would personally not buy this build. Good luck

    There is plenty of room for improvement, and overclocking of the GPU if wanted. Take another look at the Anandtech review I posted earlier. The entire system was drawing around 175w, and that's with an overclocked i7 extreme, which will use about 25w more power than the 945 in his current build.

    And he's not buying this build, he already has that computer, and is wanting to put a graphics card in it. The 750 Ti is perfect for OEM-built systems that include low wattage power supplies. People almost always overstate what wattage is required for a system to run.
  7. HELLO!
    I need to change my gpu is a nvidia gt 620 make very noise an is a very low gpu...
    i have a Dell 660 MT
    Windows 7 Home Premium 64 Bit

    and my psu http://postimg.org/image/bmk4v5r51/


    can i go gtx 750 ti???

    2 years i run my pc with a gigabyte GV-5670 (R567ZL-1GI) I was very good graphics card and good performance by seeing (not fps) but had to give back the gpu... and I never had a problem with the card....
