  Are these generally quite compatible with older motherboards, I’ve the following system https://www.nebulapc.com.au/products/osa (ASUS PRIME A520M-E - DDR4) with an intel arc a770 added. I’m thinking I need a bit more power for the card than what I have here, also maybe better quality power supply. (Have also upgraded the ram to 128gb, playing around with AI and that helps with model size)

    Just a smaller form factor, they area perfectly comparable with any modern motherboard from either camp.

    You'll have no problems with that GPU at all either.

    You definitely do not require a 1000 Watt PSU.
    While a quality power supply is a solid investment when building from scratch, I would keep what you have currently unless there is an explicit need (e.g. your system is randomly crashing). Save the money for your next build a few years down the line.

    You planning to stick with the single GPU for AI? If not, you might want to consider a bigger PSU, especially if you're going to do tensor parallel.

      Just tinkering for now so this is ok. The VRAM was pretty decent on the a770 so I went with it.

        Yeah, these tempted me, but only GGUF compatible so ended up with used 3090's

          @idonotknowwhy: How much do AI folk buy used 3090s for in Australia these days?

          I'm waiting for the 5090 to upgrade, wondering how much I can get for my used 3090 as I read that the 24Gb of vRAM will remain desirable for AI workloads.

            @ThatsCheap: Seems to be between $900 - $1300. More recently it's closer to the latter. Someone snagged a bargain for $700

            https://www.ebay.com.au/sch/i.html?_nkw=rtx+3090&_sacat=0&rt… (ebay sold items)

            I generally pay around $950 but bought one for $1200 recently.

            RTX3090 has the NVLink port which they removed for the 4090, so they're desirable for finetuning with 48GB VRAM.

            Personally, I don't think they'll drop much if the 5090 comes out with 24GB VRAM but it's hard to say.

  my 750w seems to perform well so far even with a 7800XT by the time I get a new psu will be something maybe in a few more years.

  • 

    Jayden16 on 16/09/2024 - 10:31

    Hell, my 600w performs fine for my 7900XT and 12600K. I thought I'd need to upgrade to the 750w when I upgraded my GPU but haven't had any issues in the 6 months I've owned it.

    Me too cloudie, me too.

    Been watching it closely but I think there is not enough stock just yet for a deal.

  Honestly this is an amazing PSU the thoughtful cable sleeving makes a huge difference when building in SFF PC's
