Advise for Upgrading Graphic Card | AMD Phenom II X4 945 | 8GB | PEGATRON Narra6 6.1

Hello community

First of all let me thank you all for the useful information I've found here for the last couple of years.

Straight to the point, I have an old computer (given by my father, therefore with sentimental value) that for a number of reasons I need to put back into shape (scraping is not an option). Somethings I've already done, upgrading RAM (from 4gb to 8gb, ignore HP website regarding the mobo specs, they are incorrect) and CPU (from an Ahtlon II x3 2.6 to Phenom II X4 3.0). The next, and final step since I’m running out of options, is upgrading the graphic card.
That’s why I need your help, what is the best graphic card that I can run with this specs? If GPU upgrade is necessary I will do it.

Specs:
Operating System
Windows 10 Home 64-bit
CPU
AMD Phenom II X4 945 95w
Deneb 45nm Technology
RAM
8,00GB Dual-Channel DDR3 @ 669MHz (9-9-9-24)
Motherboard
PEGATRON CORPORATION Narra6 6.1
Graphics
1023MB NVIDIA GeForce GT 430 (ASUStek Computer Inc)
PSU
300w

Thank you all so much for your help and attention.

  1. The biggest problem you have here in upgrading the GPU is that 300W PSU. The GT 430 is a 49W card and I wouldn't want to be increasing the wattage on the card, certainly at least not by much. If you stick with the PSU then I think your best bet is the new GT 1030, much faster than the GT 430

    If you are willing to replace the PSU then I believe that you could go as high as a GTX 1050Ti, anything past that will be bottlenecked by the CPU and will be a waste of money.

    Thank you for the inputs.
    A quick clarification:
    GT430 cardpower 49w | Mininum System Power Requirement 300 W
    GT 1030 cardpower 30w | Mininum System Power Requirement 300 W
    GTX 1050 cardpower 75w | Mininum System Power Requirement 300 W

    Altough I do have a 300W PSU, those 75w from the GTX require a higher PSU correct? I that case how far do I need to increase PSU capacity?

    When you said "The GT 430 is a 49W card and I wouldn't want to be increasing the wattage on the card, certainly at least not by much." what do you mean?

    Thank you again
  3. My comments are based on two facts. First, when power capacities of PSU's are stated it is a bit misleading. One 300W is not the same as another 300W. A poorer quality unit may be only able to withstand short periods of power draw close to the max capacity while a better quality unit can sustain a much longer duration in this upper zone. Second fact is that as PSU's age they lose some of their power capacity, it is just a simple consequence of the electron flow through the power circuit.

    A 300W PSU is okay for an office PC but it is on the light side for a gaming computer. Gaming results in much more sustained and heavier power draw so the chances are much more likely that the PSU will blow than if it was just used for surfing and playing cards. And when a cheap PSU blows, it might take some or even all of the other components with it.

    So my statement that I would not be increasing the base wattage of the video card reflects three things; you have a cheap PSU (an assumption but I am likely right), it is likely at least 5 years old (an assumption but I am likely right) and the system is likely doesn't have much power capacity to spare (an assumption but I am likely right). This makes increasing from the 49W GT 430 to the 75W GTX 1050 a questionable decision. It might be no problem whatsoever or it could be a catastrophe. I don't know. In truth it is only 26W but I just don't know. For the sake of a new good budget PSU ($40) you get peace of mind if you chose the GTX 1050 Ti.

    Hope this is clear, I seem to be fumbling for words here. And a 400W is likely more than enough by the way.

    If that's an HP pre-built, then that 300W is not a 'real' 300W power supply. A 95W CPU+75W GPU means you're already drawing 170W off the 12V output just for those two items. If the power supply is as old as the rest of that system, that just makes it more likely it's putting out less than the rated power. Don't be surprised if after all these upgrades the power supply fails on you.

    As to the card, the big thing I'd worry about is compatibility with that older motherboard. All things considered, I'd probably put an RX 460 2gb or 560 in there and call it good. You didn't say anything about what you plan to use this computer for, but a 460 or 560 should be able to keep up with whatever your CPU can handle.
  5. Thank you both for the inputs. You are right, the PSU was very old and I changed it for a 600w just for the sake of being safe.
    Now, regarding the card, I had the opportunity to borrow a GT 710 just to check if a more recent card would work withou any issues, altough I know the TDP (19w) is less than the GT 1030.

    This was the only GT 1030 I found availabe in my country, a Gigabyte, and I guees thats what I am going for.

    Regarding the usage of the computer, some video and photo editing when I need to bring some work home and some casual gaming, like Flight Simulator X and some older games from 2014/15/16 that I never played, like GTA IV and V.

    Thank you
  6. The GT 710 is not 'recent' in technology. It's based on "Kepler", which makes it more a 6xx series card than a 7xx series in terms of technology. The significance is the 6xx series is the last series that is compatible with either old and new motherboard bios. Don't assume that because the GT 710 works that means a 10xx series will work.
