looking to buy new GPU, not sure if I should also replace power supply

I've been looking at potentially buying a new GPU, but I'm still not sure if I will do to the current prices. Anyway if I do, my buying options are low budget GPU's, of which I'm looking at something like a GTX 1050ti or RX 560, sitting around 200 USD. This would be my first time I install out of factory components to my PC, and so I don't want to mess stuff up. I feel like I am well enough informed on graphics cards and installing them seems easy. My main problems is with power supplies, the only thing I really know is that power supplies are important, but otherwise I'm a bit clueless.

The factory power supply on my PC reads that it's "total wattage" is 286.w, with a peak of 350, which says it lasts for 30 seconds. So if I'm looking to install a GTX 1050ti for example, which recommends a 300w power supply, and consumes 75w, is my current power supply good enough? What matters more, the peek, or total wattage? I also did recently learn that PSU's rated at only peak are generally bad, so maybe just for that reason alone should I replace it? Also after looking around the for GPUs I've learned that there are some which take power directly from the motherboard and others connect to the power supply, does it matter, or is one way better than the other?

    it is hard to tell without knowing the exact model of the PSU and other components (power consumers) in your system.
    Generally, a 1050Ti without additional power connector should be fine as the total system power consumption should be well under 200w with "normal" non overclocked CPU.

    Well here is is a pic of the PSU ratings

    I don't think I have much power consumers to mention, but I got a gaming mouse and keyboard, the CPU is an AMD Fx 8300 8-core, the current GPU is a R9 255, a wifi adapter and a dvd drive i never use.
  3. if you are replacing the GPU, it should work as they both consume about the same power.
    Your PSU is actually only 216w. So it would be a good idea to replace it with a decent quality unit when you have a chance (the sooner the better).
    Good thing about good PSUs is that you can reuse them for very long time. Like 10 years is not the limit.

    since you have a crap power supply you want a 1050 ti that runs on the power of the pcie slot alone

    so make sure you double check before you buy it, if the card needs a 6-pin then your power supply is not good enough
  5. Alright thanks for the help. Also would like to know what psu brands you guys recommend please
  6. Yeah 300W Minimum try get a 400W evega or even 750W
  7. What is your budget? Do you need product links?

  8. it's not about brands, but specific models.
    It is better if you share budget and a country where you live of a link to your favorite store.
