Ryzen 9 3900X | MSI RTX 3080 10GB PC: $2545 + Delivery @ TechFast


Hi folks,

Wow, busy couple of days! Thanks to everyone who has ordered so far. Due to popular demand, here's the same base spec as Friday's launch deal, with a Ryzen 9 3900X and the PSU bumped up to the Giga Aorus 850 Gold as per recommended pairing. This will run well on the B550 Gaming X, and upgrades to X570 (Biostar GTA) and X570 WiFi (likely Asus Tuf WiFi or equivalent) are available.

You will be buying this with the MSI Ventus 3X OC shipment, scheduled to arrive in October. As with the Gigabyte October cards, there's no fixed date for GPU delivery as yet, so systems will ship as soon as they're ready after the cards arrive. You're locking in the earliest available shipping date.

If you bought one of the 3600 or 3700X systems and would like to upgrade, please email [email protected] and we can issue an invoice. The upgrade will work out the same as this pricing according to what CPU you've ordered, so there's no need to reorder or go back in queue. The PSU upgrade will be included.

Due to how we're allocating GPU stock internally, the Gigabyte cards aren't available with this new PC, but if you've already ordered one and are upgrading your CPU, you'll keep the GPU you've already ordered.

    Again I've used the Galax 3080 even though the MSI card has a much higher retail price for the comparison, and the cheapest fully modular 750G PSU on there.

  • Good deal. But if you are spending this much money, makes sense to wait for the Ryzen 5000 CPUs.

    • And skip the 4000 series? 😮


    • Zen 3 announcement is expected on October 8. Worth waiting for since you won't get this build till October anyway.

    • It's a B550, you could buy the CPU later. Wait for XT refresh if they do that maybe?

      the 12-core zen3 chip will probably arrive at the 3900x launch price of ~$950AUD. That's almost +$300, not pocket change.

    • When would be the best time to build a new computer? November/December?

      • There is never a 'best time'. Things are exciting now with the new Nvidia cards, and AMD is going to do something with their CPU lines soon, but if you need a computer now, then the best time is now ;)

        • Not all times are equal. 😉 I don't need a computer now, so if AMD is releasing the new stuff soon, it would make November/December ideal?

          • @Mistredo: Whenever thorough benchmarks are made for the new AMD stuff, basically. If your budget is lower then also throw in the RTX 3060 (not sure if there's a rumoured date on that). If you want to wait even longer you can wait to see how Intel's Rocket Lake does.

            So consider building in November at the earliest, IMO.

            Also might be worth mentioning that given the global pandemic, waiting longer might result in cheaper prices faster than usual depending on how much the industry is impacted right now. I could be totally off-base on this bit though.

  • This deal is a good sign that supply may not be that limited afterall

  • Would be good if we can have option to upgrade CPU to AMD Ryzen 9 3950X .

  • What is the postage cost to Perth?

    Has had anyone had any issues with warranty claims etc?

    • $50ish

    • Yeah build had to be sent back. First tried mailing out a motherboard believeing that was causing the issue, it was not. Ended up just sending it back to fix, they arranged the courier to collect, diagnosed fixed and returned in a timely manner proving regular updates.
      Hoenstly as far as these this go, it happens. How they dealt with it was great.
      I would recommend them personally.

    • i had a graphics card come unseated in transit despite being quite well packed, looked like the courier was exceptionally rough with it all basically - i resolved the issues myself but did email techfast with photos (mostly to cover my ass in case it died in a month or so) and they were super responsive and offered to do the right things in order to resolve any issues, i got 2 systems from them (one for my wife, one for my nephew) and both have been fine, i'd definitely recommend them.

      just remember that at the basic specs of a lot of these deals, you are using cheap components, it's not going to be the biggest, baddest PC you've ever seen with the build quality of a bentley, but for the price it's all excellent.

  • What are the wait times given 3080's seem to be on a 6+ week backorder?

  • So it would be a flat $450 to upgrade the 3700x to this?

    • +2 votes

      R5-3600 —> R7-3700X = $200 from previous deal
      Therefore R7-3700X —> R9-3900X + 850 Gold PSU = $250

      • How come $2545 - $2195 = $250? Please explain?

        • The bundled GPU in this deal is the MSI Ventus, which has a $100 higher price than the Giga Eagle from the other deal. It's the same cost price as the Giga Gaming OC upgrade (+$100). If you already purchased a system with a different GPU, you don't need to pay for the MSI card.

      • How come $2545 - $2195 = $250? Please explain?

        It’s due to GPU price difference, but it still does not add up.

  • Difference between the case options cooling/noise wise?

    • I'd stay with the MSI case. Room to add a 240mm radiator in your next upgrade.

    • +1 vote

      The Leaper Air Maxx does support a 240mm radiator mounted at the front. The MSI can support a 240mm at the top or front - front mounting would require rejigging of fans so top mounting is recommended. If you have no plans to install a 240mm AIO, the three 120mm fans in the Leaper versus 2 in the MSI will have airflow benefits, no doubt. Construction quality wise, they are equivalent.

  • Deals like this makes me so jealous.

    Just wanted to give Techfast a huge shoutout for such a fast delivery.
    I bought R7-3700X: $899 + Delivery from this deal on 11/09/2020.

    Got it delivered today. Waaaay ahead of the 14 day shipping.

    Thanks Luke

    Happy to recommend to anyone.

    • You got a bit jipped. The deal linked in Ops post for the 3700x with 3080 is $2195 where as you paid $899 for one with no GPU, $1296 difference.

      An extra $1296 would've gotten you a $1400 GPU, a 480gb ssd vs a 240gb and a 750w gold PSU vs 650w bronze.

      I guess it benifits you if you never intended to put a 3080 in it and use something cheaper instead.

      • Yeah, I never intended to purchase the $1400 GPU, I bought 1660 Super.
        But the upgraded PSU and SSD makes me jealous.

        @luke shed some love for this poor fellow

        • +1 vote

          Different pricing structure for the components. We got an insane deal on Giga PSU, MB and GPU to make the 3080 deals possible. We made nothing on the the No GPU systems so there's no love to shed on those systems sadly!

          • @luketechfast: Hi Luke. I ordered the r5 3600 3080 system but don't really need a new rig until December. Do you see yourself doing any similar deals over the next few months with the Asus strix OC by any chance, or a 20gb vram version? Weighing up if I buy now or wait.


  • mmm tempted to withdraw my super to get this deal

    • Not a good idea.

    • After speaking to my mortgage lender friend - I wouldn't recommend it. Apparently if you withdraw from your super, the banks will assume you are in financial hardship and are not able to lend you any money for a minimum of 6 months. This will override any credit score that you have accumulated.

      • +2 votes

        The credit score one is a myth

        Question. Will accessing my super early impact my credit score or reduce my future borrowing power?

        Answer. No, a super withdrawal isn't considered a form of credit, so it won't be included in any official credit report. You can learn more about what factors impact credit score or what gets recorded on your credit report here.


        • Awesome. Thanks for clearing that up. Then it must have been an internal decision by CBA to not lend to anyone who withdrew their super rather than impacting the credit score.

          • @damihi: How would CBA know if the borrower withdrew their super or not??

            • @Homr: I have applied for a preapproval in August with another bank, as part of assessing my loan amount, I had to present 90 days worth of super statements, and then banks can ask for 3-6 months worth of bank statements (they will ask if they see how you have a massive deposit in your account that isn't salary). With lump sums they don't treat it as genuine savings

  • Can anyone advise if the b550 is good enough to handle the newer zen 3? I bought the 3700x and b550 and seeing everyone talking about the zen 3 makes me feel a bit nervous. If the zen 3 is a big increase in performance I might just upgrade the cpu itself next year.

    • We don't know much about Zen 3 other than yes it will be compatible with the B550. I got the same pack as you with the plan to upgrade if the need and price make it worthwhile (I don't anticipate this any time soon tbqh)

    • Be aware there may be no upgrade path for next gen ryzen on the current gen motherboards, especially at the low end.

  • Can we place order and get shipped soon, then get the 3080 shipped separately when it arrives?

  • Aprox delivery timeline please?

    • +2 votes

      Just reiterating what's in the deal: You will be buying this with the MSI Ventus 3X OC shipment, scheduled to arrive in October. As with the Gigabyte October cards, there's no fixed date for GPU delivery as yet, so systems will ship as soon as they're ready after the cards arrive. You're locking in the earliest available shipping date.

  • how is the review for the MSI Ventus 3X compared to the others?

  • TFW you go from shopping for a GPU to considering a whole new system.

    I don't think I've ever seen so many branded parts in a techfast build, very nice!

  • Coming up as $2744 when i up the ram to 32GB

  • how are you building a whole new build for 2.5k when it would cost me almost 2k to update just cpu+gpu on my dated z390 based desktop to i9 9900 and rtx3080…

    value here is pretty crazy. not sure what i'm missing

    • Magic!

      Actually the Magic of bulk order pricing :-)

    • If you add the rest of the items from his parts list, that amounts to ~ $500… good deal nonetheless since they're not charging much of a premium but rather making the money off the bulk discount.

  • Do you guys reckon 3900x is a good upgrade from 3700x for $200 (the gpu is $49 so I removed that part)?

    • If just gaming, then it's not necessary. If streaming, rendering or doing anything else that benefits from lots of threads (chrome tabs don't count), then an extra $200 for 50% more cpu cores is well worth it.

  • Some hơn the price was $2745 for me …

  • Man that's a tempting price.

  • When I upgrade the ram from 16gb to 32gb. The price is $99, however, the total price jump from $2745.00 to $2944.00. How it is possible?

  • Hi Luke, do you think i should upgrade the PSU to 850w from 750w from previous build, if I need to upgrade to zen 3 in the future
