Budget PC build for 3ds Max

First, it would be better if you gave a country of purchase and a budget. Country of purchase makes a huge difference to relative pricing and availability. Based on your listed PSU I will assume Romania (more on the PSU later).

Next we have good news and bad news. Bad news, the GT 740 will not be enough, it would be so slow during rotating, zooming, etc that it would make it impossible to use 3ds Max. I recommend the GTX 1050 Ti as a minimum.

But the good news is that if you will not be rendering on this machine then you only have to worry about single core performance as 3ds Max will only use one core at at time. This allows us to use step down in the CPU to save money as long as we maintain the single core speed. Went with a Skylake build over a Coffee Lake to save money and performance will not be affected. But if you plan to ever render or use other programs then this might not be the best way to go.

For storage the best thing would be an HDD plus an SSD. Actually an HDD, SSD plus an SSD scratch drive but that is for high end machines. If you go with a straight HDD you could end up waiting for storage calls for program information. As a compromise I therefore recommend a Hybrid HDD. Commonly used code will be stored on the 8GB SSD making usage that much faster.

Last, I am highly suspicious of this PSU. I could not find any information on it, just this other model by Myria

If you scroll down to the "Alimentare" section under "Specificatii" you will see that it has 20A on the 12V rail for 240W of power. The 12V rail powers the CPU and GPU and the vast majority of the system. This is not a 500W PSU, more like a 280W. This happens all the time with cheap PSU manufacturers, the label doesn't match what is inside the unit. But the real problem with cheap PSU's is the lack of circuit protection, so if they overload they often destroy some or all of the computer. Selecting a cheap PSU is a common mistake with novice builders. And you have to look at the specific model, ordering from a known brand like Corsair does not guarantee a good choice.

For the build below all pricing is in Romanian RON and specific page links for the components are below the build. Went with the i3-7100, fast 3.9 MHz core speed while being much cheaper than a Ryzen 1600 (469.72 vs 949.99). Picked 2x8GB of DDR4 2400 MHz RAM, you might actually want to upgrade to 32GB later, you still have two empty slots to do so. You might want to shop around for RAM as I found the choice below very expensive. You will want to find DDR4 2400 MHz with a lower CAS number. Seagate Firecuda HHDD and a reliable budget PSU with circuit protection. No monitor, OS, keyboard/mouse or Wifi card included in the build.

Let me know if you have any questions.

For the PSU you a split rail 12V system, meaning that two separate circuits to supply the 12V current. This used to be the standard for better PSU's so that is positive. And it was manufactured in September of 2014 so it is less than 5 years old. This is also good because as PSU's age they lose capacity. No idea about the circuit protection present though. I would be comfortable with using this PSU and maybe upgrading in the future.

If you can test the 740 in another system that would be good but make sure the system is powerful enough that the GPU will be the bottleneck process. You can assess its performance by trying to rotate or zoom larger images.

For the RAM I highly doubt that 8GB will be enough but it is very dependent on the image size and resolution. Usually they say 32GB is the minimum.

Dual channel ram is about 2-4 faster than the same RAM speed run in single channel. This is why you buy RAM in pairs, so it can run in dual channel mode.

Since your total RAM GB will be lower I would spend the money on 2400 over 2133. But I would choose 16GB of 2133 over 8GB of 2400.

The mobo you have listed will work, it is just not as good as the one I listed. You will not be placing a big burden on the power phases of the mobo so something lesser would be okay.

To get the build down to budget we will have to downgrade the CPU to the Pentium G4560, bit of a hit but not much, they are surprisingly powerful CPU's. You might have to look around as they don't seem to be in stock at either of the websites. You will have to stay with the GT 740, hoping that this will be okay. G4560 will overpower it so there is no bottleneck there. In fact there would be no bottleneck with a GTX 1050 Ti.

Also had to drop the HHDD and just go with a plain HDD. Again, I would really try to find the extra RON to get the hybrid. Or you could just get the plain HDD and save up for an SSD.

Here is the new build, used a normal Patriot memory but it is DDR 4 2400 MHz.

With the small current budget and as long as you can live with the slower GPU and lower RAM for the time being, then I believe that upgrading later is the way to go. This will allow you to manipulate larger files later on. Getting a very low end complete system now might lead you to the same situation you currently are in.

For the 1050 Ti don't worry about the GPU speed, they all run about the same. Cooling, noise and price are more important.

Just one last point, when purchasing the RAM upgrade be aware that the system will slow down all the RAM to the speed of the slowest stick in the system. So if you have 1x8GB of DDR4 2133 CAS 15 and later buy 1x8GB of DDR4 2400 CAS 17 it will run at 2133 MHz CAS 15.
