470
3900X-SEP

Hi all,

We've up-specced the deal from July on 12 core/24 thread Ryzen 9 3900X productivity PCs to feature high specs across the board. If you don't require 32GB RAM the previous deal at $1348 (16GB 3000MHz/240GB SSD) will still be available for a short time.

Win 10 Home is preinstalled (unactivated) as default, but you can request Win 10 Pro to be preinstalled in the Notes field during Checkout if you want that (or purchase either activation key for that full activated OS to be installed).

Ryzen 9 3900X Productivity PC

  • AMD Ryzen 9 3900X
  • GPU choices from RX 550 4GB (base config)/ RX 580/GTX 1660/RTX 2060/RTX 2070 Super/RTX 2080 Super/RTX 2080 Ti
  • Biostar X570 GTA motherboard (WiFi mobo upgrade available - first 5 guaranteed Asus TuF WiFi as they currently are on hand)
  • 32GB 3200MHz RAM (brand may vary - updated taking feedback into account)
  • 480GB 2.5" SSD (1TB NVME upgrade option available for fastest storage)
  • Gigabyte P650B 80+ Bronze PSU

  • why do people actually buy this? Isn't everything here so subpar for the 3900x, slow RAM, low tier PSU, etc.

    • Every time luke posts a deal someone says this… it's upgradable, some people need low budget, you can upspec when purchasing, good enough is better than over built when you're on a budget… there's heaps of reasons to buy or not to buy.

      Same thing could be said for the 3600C18 memory for $99 from amazon. Why would you get that when you can get 3600C15 for $100 more?? the C18 is junk right?

      • that's not a fair comparison, choosing 3200Mhz is only $1 or 2 more expensive than 3000Mhz from looking at RAM on Amazon for example and pairing a sub $100 PSU with a $700 CPU just doesn't make sense, essentially it would work but I think no body would every built a system like this if they were to build it themselves.

        And if you're on a budget, just buy from the previous deal cause all the upgrades look like they're going to need to be swap out anyway, you're paying $150 for "below standard RAM" and 240 GB SSD

        • I agree ram should be 3200mhz as that's what AMD specify for this CPU.

          Generally most of the changes that people say should be done to these techfast machines adds up to $1000, I stand by my double the price for better comment.

        • pairing a sub $100 PSU with a $700 CPU just doesn't make sense, essentially it would work

          It makes perfect sense as evidenced by you saying it would work lol.

    • It is, but sometimes people have to learn the hard way that cheap and inexpensive are not the same thing.

    • Yeah they get you in with the 3900x and then give you no name GPUs, RAM and poor quality everything else. Will always be better to build yourself unless you have no clue about computers

      • Like I look at this and the only things you would keep are the CPU, the case, and GPU if you're not gaming

      • What are the no name brands of RAM and video cards? Certainly not Galax.

          The RX 550 are RX 580 are from Biostar, the 2060/2070S/2080S are from Galax, the 2080 Ti will vary because they're hard to get. The RAM brands and models may vary.

          • @luketechfast: So no names here then!

              @Clear: I wouldn't say that. We have G.Skill Ripjaws, HyperX, XPG and PNY on hand and others incoming. As we use a variety of brands and models, I can't say with certainty what will go into any one build unless I set the product up like TechFast Express systems, with stock set aside specifically for those builds, which hasn't been applied to this system.

    • You're not the target market.

    • PSU has no effect on stock performance.

      If you really want to save some money consider pairing it with a A520 motherboard https://www.youtube.com/watch?v=TDQqLkmcFqI

      • Incorrect. Bad PSU will blow your system up, and you will have zero performance πŸ˜‰

    • the components are priced well, even if you dont want them all. you could always ask for it to ship unassembled and use the parts you want and buy whatever else you wanted. then build the kids a PC from the leftovers :)

    • Similar deal to the one from last month with extra RAM and bigger SSD and of course more expensive. Actually works out worse than that deal with stronger AUD.

      https://www.ozbargain.com.au/node/554641

    • Because the buyer will know the system works since the people building it have done so many they could assemble it in their sleep, because it's advanced enough to use but basic enough to modify, list goes on.

      I could buy this, dump in a spare card I have, and it would work perfectly for CAD. In fact I have a spare GTX1060 still unopened and 2x Nvidia Shields which give me no end of grief.

      Or, like when I built my gaming rig a year ago, a person could spend months shopping for the right parts at the right price and then assemble it once everything is purchased …. and hope there's no conflicts.

      TL:DR These deals target a certain group of buyers and, if you must ask this question, then you're not part of that group.

  • Well… Previous deal really looked good. However taking a quick look, most of the "upgrade" options are not cost effective. Guess that's where they're making money from… If you "upgrade" your graphics card you pay as much as the new card and you're basically to forfeit the value of the base card. So bad value for "upgrade" and the base gpu… RX 550… Just doesn't make any sense with 3900X - even if you don't need gaming power there are simply cheaper and better options. To make the most out of this deal you'll have to buy the base build and sell the parts you don't need …

      Our RX 550 buy price is lower than any other GPU that will provide output for the CPU so there's no need or cost advantage to go lower.

      • Well low cost but certainly wouldn't be $0?
        Upgrade from RX550 > RTX2080S costs $1049, but then you could just buy the same 2080s yourself for the same price and keep the 550. Should be reflected to be at least $50 cheaper imo. Looks like good value without upgrades though :)

          A lot of clearance cards are available at the end of the gen for cheaper than we bought them right now. We don't buy from retail and have supply agreements in place weeks and months out that can't always be altered.

    We've taken the feedback on board and bumped the RAM to 3200MHz.

  • RX550… The OzBargain GPU of choice for those thiftily awaiting next gens

  • Any good deals for Ryzen 7 3700x builds?

  • So if i get this, and want to put say a 2080ti in would I need to upgrade the PSU

    • Probably not, as Nvidia recommend 600w and a 80+ Bronze PSU aint bad, just less efficient at getting the 650w, not even that much less efficient I might add, but enough to make a difference on your electricity bill :P.

  • A question, I use my pc in my study room. It gets really hot summer time and currently if I leave my pc on during the day I also have to leave the aircon on.

    Would a pc liquid cooling keep the cpu cool enough even if I leave the pc on during a stinking hot day..

    Not sure if it is worth the extra money but also want to protect my cpu

    • Short answer is yes, but AIO also have some downsides.

      That said, I've lived most of my life through NT/QLD and now only use AIO for cooling my gaming rigs.
