Should I buy an AMD Radeon HD 7750 and a new power supply?

I want to upgrade my video card because I've got an NVIDIA GeForce GT 620 and a 300W power supply, I've got 86€ max. to spend so I think the best I can get is an AMD Radeon HD 7750 for about 66€ and a power supply of more than 300W for about 20€

  1. well, gt620 is merely a very low end card and hardly to play any games today..

    7750 is very efficient graphic card..
    a good 300 watt psu from well known brand (antec, corsair, seasonic, etc) should be enough to feed power to your system..

    but if you only have a generic powersupply, well, you have to replace it..

    It's an HP power supply, it's ok?
  4. It's good. Just make sure you buy Power supply from well known brand, it can be even less wattage (300-400w)

    My current power supply is an HP, it's ok?
  6. How old it is? I think it should be good for your system, you will use less than 150w

    I don't know how old is the power supply, I bought the prebuilt computer about 3 months ago.

    What about an AMD Radeon HD 7770? It will be ok with my HP 300W PSU?

    Difference is 25 watt, so it should be ok.


    Ok then, I will go with the AMD Radeon HD 7770

    Just make sure you have 1 6pin PCI connector if you plan to buy 7770.
    You can also use molex to 6 pin.
  13. scrap the radeon 7750 and get a 7770. You will see around 5-10 + fps gain for an extra 10-15 euro.

    You can get a good xfx 450w psu for 40 euro: http://www.amazon.co.uk/XFX-Edition-Bronze-Wired-Supply/dp/B005FPT38U/ref=sr_1_2?ie=UTF8&qid=1387816657&sr=8-2&keywords=xfx+power+supply

    An xfx radeon hd 7770 is only 100 euro: http://www.amazon.co.uk/XFX-DisplayPort-Dual-DVI-Graphics-FX777AZNJ4/dp/B009K274H6/ref=sr_1_5?ie=UTF8&qid=1387817030&sr=8-5&keywords=amd+7770

    You an always downscale and get a a 400w psu to save money. Even 400w is plenty

    What do you think of buying an AMD Radeon HD 7770 and using my HP 300W power supply? (It's because I haven't got more money)
  15. A 300w psu will run a radeon 7850 smoothly, so you are fine with a 7770.
    But seriously look up 7750 vs 7770 benchmarks. Definitely work the extra cash
  16. Molex to 6 pin ( if you don't have cable coming from PSU like in second link):
