Building a perfect PC to buy on Amazon

We want to assemble a desktop PC by choosing the best components available on Amazon "> How to choose the parts of the new computer to assemble.
Before purchasing the components, we should equip ourselves with all the very useful tools during assembly, so that we can facilitate the task later; below we have collected a series of tools to be purchased together with the PC components:

1. TOPELEK GEDS009AY - 58 in 1 Repair Screwdriver Kit (13 €)
2. Cable ties - Cable clamp - 100pcs (€ 5)
3. Linkax High Power LED Flashlight Flashlight LED Flashlights (7 €)
4. Inateck pack 4 x cables, SATA III cable (8 €)
5. ARCTIC MX-4 Thermal Conductive Paste CPU (10 €)
6. APC PM5-IT Surge Arrest Essential Filtered Outlet (18 €)
7. Inateck 2 x 2.5-inch to 3.5-inch SSD chassis mounting kit (8 €)

The components for a perfect PC on Amazon

Below we will find the best quality / price components that we can buy directly from Amazon.

Processors

Processors can be produced by Intel or AMD: both manufacturers are reliable, but usually we tend to prefer Intel processors when we need more power, while AMD tend to be slightly cheaper and well balanced (as well as powerful, especially in Ryzer versions).
The best Intel processors we can buy are:

1. Intel Core i5-9400F (€ 163)
2. Intel Core i5-9600K (€ 254)
3. Intel Core i7-9700K (€ 367)

If instead we wanted a latest generation AMD Ryzer processor, we can choose one of the following:

1. AMD Ryzen 3 (€ 92)
2. AMD Ryzen 5 (€ 143)
3. AMD Ryzen 7 (€ 296)

To learn more about the differences between the two CPU manufacturers, we recommend that you read our guide to the differences between Intel and AMD processors and Intel Core i7 and i5 CPUs .

Motherboard

The motherboard is a very important component in the computer, since it distributes energy and offers connection to all the other components, functioning as a sort of "conductor" in the PC. Obviously there are motherboards for Intel and motherboards for AMD: we choose the right card based on the processor, otherwise we risk the incompatibility (a motherboard for Intel processors is not compatible with AMD processors and vice versa).
The best motherboards for Intel processors reported above are:

1. Asus ROG STRIX H370-I (139 €)
2. MSI H370 GAMING PRO CARBON (149 €)
3. Gigabyte Z390 AORUS PRO WIFI (202 €)

If, on the other hand, we are looking for the motherboards for AMD processors mentioned earlier, below we find the best ones on offer:

1. Asus PRIME B450-PLUS (€ 99)
2. Gigabyte X470 Aorus Ultra (144 €)
3. Asus PRIME X470-PRO (173 €)

We don't know how a motherboard works? We can deepen the topic by reading our in-depth analysis on How the motherboard works .

power supply

The power supply is a very important component in the computer, since it supplies electricity to all the components. Choosing one that is not very powerful and efficient can cause sudden shutdowns, especially when we perform the heaviest operations (games, video editing etc.).
The best power supplies that we can install on our PC are:

1. Corsair VS550 550 W power supply (€ 47)
2. Cooler Master MasterWatt Lite 700 W (61 €)
3. Corsair TX650M PC Power Supply, Semi Modular (89 €)

To find out more, we recommend reading our guide on Which power supply to choose for the PC and how many Watts are required .

RAM

RAM allows you to temporarily save information as long as electricity is present. When we start the PC, the operating system and programs are loaded into it, so that we can use them at the moment.
Currently the type of RAM is DDR4, so we will have to install memory banks of this type in order to create a modern PC. The best RAM modules we can buy are:

1. HyperX FURY DDR4 8 GB (2x4 GB kit, 53 €)
2. Corsair Vengeance LPX 16 GB (2 X 8 GB), DDR4 (71 €)
3. G.Skill Trident Z RGB 16GB DDR4 16GB DDR4 (€ 107)

To get to know all the secrets of RAM memories up close, we recommend you read our article on Computer RAM types: DDR, shape and speed .

SSD

As internal storage unit we will use an SSD, which has effectively supplanted the old mechanical hard disks (now too slow for daily use). The best SSDs with SATA cable are available below:

1. SanDisk 500GB Ultra 3D SSD (71 €)
2. Samsung Internal SSD 860 EVO, 500 GB (73 €)
3. Samsung Internal SSD 860 QVO, 1 TB (109 €)

If instead we wanted to take advantage of the new M.2 SSDs, which can be connected via a special PC slot, we can see the best products below:

1. WD Blue 3D SSD M.2, 250 GB (€ 49)
2. Samsung SSD 970 EVO PLUS M.2, 500 GB (111 €)
3. Crucial MX500 Internal SSD M.2, 1 TB (122 €)

If we don't know which SSD to choose between the two available formats, we can clear up our ideas by reading our guide on Which type of SSD is better: SATA or PCIe?

Homes

The case is always a matter of personal taste: there are those who prefer it classic, those who are more subtle and those who prefer it "sborone". Thousands of houses are available on Amazon, the most beautiful ones we have included in the list below:

1. Case NOOXES X10 (€ 33)
2. Thermaltake Versa H21 (€ 35)
3. Noua Noob X7 White (39 €)
4. Empire Gaming - PC Case Gaming WarFare (52 €)

Other cases can be viewed here -> PC cases on Amazon.

Graphic card

Obviously, the dedicated graphics card could not be missing, very useful for games and programs that require advanced 3D acceleration. The best video cards we can currently buy are:

1. ASUS DUAL-RX580-O8G Radeon RX 580 8 GB (€ 259)
2. MSI Nvidia GTX 1660Ti Gaming X 6GB (320 €)
3. Gigabyte GeForce RTX 2060 GAMING OC Pro 6GB (€ 378)
4. MSI V372 NVIDIA GeForce RTX 2080 8GB (835 €)

If we want to deepen this thorny topic (where to understand the difference between one card and another could become a big business), we recommend you read our guide to the best video cards for PC .

Other accessories and peripherals

To complete our powerful desktop PC, the following components must not be missing:

1. HP 22W Desktop Monitor 22 "Full HD (1920 x 1080) (84 €)
2. Logitech C270 HD Webcam (22 €)
3. Logitech Desktop Keyboard MK120 and mouse (17 €)

5. UGREEN USB 3.0 SD TF CF MS Card Reader, Card Reader (13 €)

Conclusions

In this guide we have included everything needed to create a large PC to assemble, capable of performing all the tasks that require great computing power (currently one of the few purposes for which it is still convenient to keep a PC in the home, given that the rest can be replaced by notebooks, tablets and smartphones).
If we don't know how to physically assemble the various pieces, we can learn the rudiments of assembly in our guide on How to assemble a PC and assemble computer parts .
If, on the other hand, we are looking for a desktop PC to be assembled with different types of budget, we recommend you read our guides on How to make a good 300 Euro desktop PC, how to assemble a medium level PC of 600 Euro and finally What is the most powerful PC with the best hardware ever .
