Is my psu enough to work with gtx750ti?

I'm planning on buying a new graphics card to replace my broken gt420. I have a 450w tt-450nl2nk btw. Is this good enough? Else, what are cheap psus that would work with gtx750ti? Thanks!

  1. It should work OK with a GTX 750 Ti, they don't require a lot of power. 300 watts is typically the minimum recommended PSU.
  2. I installed the card and played for a while, but after a couple of hours, I just had this black screen and buzzing sound from my speakers, I reset my pc manually and now nothing appears on my screen.
  3. Try removing the card and see if you can reboot it.
  4. Look on Coolermaster's website or MSI for power supply calculators, you input your pc specs, it gives a rating for psu power. Many say this is false, check it out.
  5. I tried reseating the card but nothing happened unfortunately. No signal appears on my monitor. Could this be the card or the psu may also be the reason? I've also tried the onboard display and it booted normally.
  6. The power calculator will allow you to add your pc specs to see the amount of power is used under full load.

    Just to see if you have enough power, if not it could cause damage to the gpu and motherboard.
  7. What motherboard do you have? The graphics card may not work on older motherboards with a non UEFI Bios or some OEM motherboards that limit power to the PCIe slot.
  8. I went to the coolermaster and the recommended wattage was 300. My mobo is an asus p8h61 mx usb 3

    It should work on that board. Did you test the old graphics card in another system? You need to do that with the new one as well. If they work in another PC, your motherboard may have failed.
  10. I have already tried my old card at my friend's pc it didn't worked so it really made up my mind to buy a new one. Haven't tried the new card though since he is out of town.

    Those calculators will do the exact opposite, they are horrible.
  12. I was able to try the card in my friend's pc and it didn't worked. LOL. Got it RMA'd and now it works perfect. Anyhow, I also want to replace my PSU just to be safe. Any thoughts about 450w fsp hexa and corsair vs?
