AMD Enthusiast Gaming Build: PSU

While all of the components we are selecting here today are what we would go with, and priced from vendors we trust, it is always a good idea to shop around as deals on these, or other good options, pop up from other reliable vendors all the time. With that said, let’s dive right into the next order of business.

Now we move on to what is often the last thing users consider when building a system; the power supply. Even though it should be close to the top of the list it often isn’t, and we all get why. It is usually a rather boring item in the build whose contributions are easily missed. Well, that is until things go south! Our choice today though turns this all on its ear a bit as the ASUS ROG THOR 850 with its OLED screen, RGB integration, and clean lines not only has the performance we need, and the quality we deserve, but it looks good doing it! Sure, you pay a premium for that but when you look this good that almost doesn’t matter. As Paul Johnson said in our review of the unit, “The ASUS ROG THOR 850W is an excellent to outstanding unit today as ASUS has indeed dropped the hammer on the competition. The ROG THOR 850W gave us excellent build quality, excellent voltage regulation, excellent DC Output Quality, and excellent Transient Load results while also being very quiet. That is a seriously impressive run that leaves us with very few things to say other than, WOW and what is the price?

That said it almost doesn’t matter you can get essentially the same power supply without those bells and whistles from Seasonic in the guise of the PRIME PX-850. Sure you give up the bling, but aside from that (and some cost), you are still walking out the door with an extremely high-end unit that will serve you well in this build and probably your next as well!

  1. I agree with almost everything you said in the build. I would say that stepping down to a previous gen of Samsung SSD to a 960 for NVME might be a better move but I’m not as familiar with the other brands. And I’m a little surprised you didn’t throw some corsair memory in there.
  2. I would do the following:
    CPU: AMD 3700X, good speed, 4300 autoOC,cheaper,how many cores do you need?
    Board: ASUS ROG Crosshair Hero,a little more cash buys you the best BIOS.
    RAM 32 GB Corsair Vengence, 3600 speed,cheap price,more GBs
    GPU: AMD Radeon 5700 XT……save some cash,Ray Tracing is BS, excellent 1440P
    gaming.
  3. Mid-high end is probably a good way to describe this. You certainly don’t make many compromises, it’s high quality all the way through.

    Good way to highlight your own reviews as well. Was an interesting read. May consider taking it a step further in a follow on if you are putting this together as a real build and not just a hypothetical shopping list : showing some pics of the build as it’s going together, maybe a few comments on how the build is going, and a few light benches to show how it performed after you got it running.

    That’s certainly a down the road sort of thing – the parts from the reviews are scattered across a few states right now!

    I want to see how this sort of article does for us and if it performs well from an affiliate link and organic search perspective. We’ve got an Intel based build that will be out soon, and may do a few variations at different price points. If it does well, then we’ll expand it to pictures of the actual build and likely do a video as well.

  5. Thanks Brian for all your hard work in putting this together!

    Just sharing some of my experiences with my most recent build since it has some similarities to this build. I went with the 3700x. Don’t need the extra cores and it’s plenty fast for now. Used a MSI x570 board as well just a WiFi variant since this rig is in a room without wired LAN access.

    GPU: Also used a RTX 2080 Super. Paid a little less than what I did for my 1080Ti three years ago. It’s an awesome card and when overclocked they really go to another level. I wouldn’t really consider it for 4K though. Just not enough Vram at that resolution unless playing a very non-demanding game which in turn would defeat the purpose of a 3900 or 3950x. Although at this point in time I wouldn’t recommend a 2080Ti to anyone either since we’re likely months away from the next gen. For 1440p the 2080 Super is amazing. With the exception of RDR2 I can usually set everything to max, including ray tracing, if DLSS is on, and hold 50-70 fps. Turn a few things down, just a little, and solid 60+ fps is easily achievable. At 1440p I’m usually seeing 4GB to over 7GB for demanding games in 1440p. For less demanding things 80-120 is no problem. These are the upper of the RTX family but I feel are vastly underrated for what they offer. For those playing games at 1440p this card will really let you enjoy ray tracing if that’s not your thing then it still has plenty to offer in the extra cores and faster Vram.

    Wraith Prism: Get’s the job done. I agree can be a little noisy. Just as you mention be aware of clearance. If planning on using the PCIe 4.0 slot for the GPU it can add to heat issues for the GPU. One side of the block vents directly within about 10 mm of the back of the GPU. If I leave the BIOS at auto clocks will average anywhere from 4000 MHz to 4175 MHz but at full speed hangs pretty much in the 4200’s and occasionally over 4300 MHz.

    Down the road I might go AIO or even a closed loop but not really planning much until my next GPU upgrade.

  6. RAM 32 GB Corsair Vengence, 3600 speed,cheap price,more GBs

    The reason for the choices is that Sammy B has the best (sub)timings of all the DDR4 memory chips by a mile, though I would personally repeat my recommendations from another thread;

    with a relatively cheap, if more expensive THESE DAYS Patriot Viper Steel kit
    And a faster Team Group bin that’s slightly more expensive. (but still much cheaper than the gskill kit in the article)

    With what the Viper Steel sticks go for these days, you can grab the 3200 CL14 G.Skill sticks if they’re the same price; as I myself am using those and gotten perfectly good results with them.

    If you want a higher-end option than more-or-less-the-same grade of b-die, then you should rather be looking at non-RGB* sticks of dual-rank b-die;

    Such as this 3200 CL14-14-14 2×16 GB kit, though it’s a bit harder to find consistent Sammy B dual-rank sticks, as the

    Code
    (Frequency / tRCDRD) >= 200

    rule doesn’t always appear due to dual-rank b-die potentially being a little temperamental.
    A dual-rank b-die kit will have a slight (I can’t tell for sure, as I have not tested it myself due to price :)) performance advantage over single-rank sticks, while the dual-rank frequency penalty doesn’t really matter as you’re still capped by FCLK.

    * RGB is a detrimental element for signal integrity, which dual-rank sticks already have a bit of a problem with

    The reason that you would shoot for Sammy B memory is because memory is by far the biggest bottleneck for Zen 2 performance – and you’re stuck at 3666-3800 MT/s due to your FCLK capping out at 1833-1900 MHz, seemingly depending on power quality (cleanness).
    Which means that memory types such as Micron E that can easily clock up past 4200 MT/s, but suck at subtimings, find themselves getting stomped if you’re after serious performance rather than Pretty Good.

    Not to mention, that in my experience squeezing every penny out of my 3200 CL14 kit – Ryzen DRAM Calculator uses very safe Samsung B-Die settings, thus you’re unlikely to have any problems whacking them in – all while getting 90% of the total benefits for 10% of the effort. It’s a great deal – and Zen 3 will still be on DDR4, so your investment into speedy memory will last.

    I’m also not certain how much better dual-rank BAD-die will perform, given that they’re likely to have different subtiming walls than single-rank – but seeing that DRAM calculator doesn’t really spit out settings too different between the two, and seeing that I would recommend that you’d at least use those, it shouldn’t really matter.

    Now, none of this really matters if you’re for some reason stuck in 60 Hz land – but even LG’s OLED TVs with great input latency are putting out 120 Hz these days, and if you’re really out for a Visually Pleasant experience; they’re the best place to go these days, especially seeing that models from 2019 and onwards undo burn-in during standby.
    oh and of course, if you’re shooting for 240 Hz madness – RAM overclocking is mandatory for a proper experience
