Intro

Throughout the 3+ years I’ve used this website and spent some time in subreddits like /r/buildapc, I’ve found that people tend to not have much understanding of what they're talking about or how what they're talking about works. I’ve been in, and still am in such a place in many areas, so I get it. But for someone to mitigate this issue for themselves, they need to find the right information, and more importantly, correct information. Problem is, this isn’t always easy, especially if you want to go in-depth.

There's a lot of good information out there regarding PC hardware and peripherals. From PC components and peripherals, to networking and audio, the goal of this post is to consolidate links to this information in hopes of helping to make understanding of these topics more widespread. In addition, unless otherwise noted, links are given in a suggested order within a sub-section, from top to bottom. This post is meant to provide a structured learning experience, where one can start small and build their way up. As such, every link is included for a reason. While the vast majority of links are included for this reason, a few (such as some in the PSUs section as an example) are there for clarification or a more easily understandable explanation. Sub-sections aren't necessarily layed out the same way, although for them it is generally assumed you have gone through any "basics" or "general" sub-section before others in a section (excluding anything categorized as Advanced) if there are more. The information that can be learned from here isn't practical by itself (for practicality, see the complementary thread linked below), but can certainly help you to figure out how to make decisions regarding hardware, understand reviews, and of course, know how everything works to some extent. To put your newfound or otherwise knowledge to some use, I have added a list of good reviewers for different things.

This thread is aimed at the curious, from beginners to those who want to get more in-depth without reaching for entire books (which are also suggested when I know a good one). Beginners can learn lots of what they should know, and those wanting to know more can find some resources to learn what they want to. Make sure you don't run before you walk or bite off more than you can chew, because there's a lot of information here to take in and it can get pretty in-depth at some points. I hope that if everything is read or watched through entirely (excluding Advanced category, including the complementary thread linked below), you can achieve a well above average level of hardware knowledge compared to the typical PC-related forum user, and learn almost all that is worth knowing.

Any sections or sub-sections marked with (lacking) I believe have some sizeable gaps of information and so require learning material of which I don't have off-hand at the moment. It's there mostly to mark where I should look to add on to if possible. Do note that my ability to know what is actually in real need of additions is still limited by the natural limitation of my own knowledge. Any section or sub-section marked (lacking, see complementary thread) has informational gaps that are filled thanks to the complementary thread.

Some informational gaps exist because trying to fill them here goes against the focus of this thread one way or another, due to the articles or videos in which these gaps are filled. Instead of doing that, I made another thread to complement this one that helps to fill in the gaps and also give information on topics that didn't quite fit this thread such as the actual act of PC building, troubleshooting, computer and online security, and many more individual smaller topics. At the same time, that thread provides many links for various guides, tutorials, how-tos, and useful websites or webpages. Check it out here:

https://pcpartpicker.com/forums/topic/215183-526christians-complementary-thread

If I notice any incorrect or misleading information I will make note of it, along with anything important to know/remember and any clarifications I feel are worth pointing out.

If a link does not work, use archive.org as nearly every link is archived there (I go through them all and archive through that site, even individual pages). Some such as Tom's Hardware links however aren't archived because they don't allow it, and YouTube videos aren't archived for obvious reasons.

Anything marked Recommended is highly recommended by me to read or watch. Do note that it is still assumed you are following the suggested top-bottom order of reading/watching before getting to the Recommended material.

As always, keep in mind the age of the learning material. The fundamentals of everything have stayed pretty much the same over the past decade or so, but the details may be different.

Link categories

Beginner: Anything in this category covers things beginners should know for a given topic, and does not go in-depth. These tend to be a good starting point and in most cases are easy to understand.

Beginner/Intermediate: Anything in this category is a combination of beginner and Intermediate in terms of depth, complexity, and possibly length. These are easy enough to understand provided you know at least some necessary basics.

Intermediate: Anything in this category may go into topics not covered by material in beginner category, go even more in-depth about them, or both; but without reaching Advanced category levels. These may require some prior knowledge and/or may benefit with use of glossaries provided in this post, and so are not very beginner-friendly. These will also typically be longer than what is in the first two categories.

Advanced: Anything in this category gets in-depth and technical. These are best left for those who are serious about learning more, and almost definitely require some prior knowledge to understand it. Everything in this category is at least a bit long.

This is so you can get an idea of the relative complexity and length without having to look at it. Categories are chosen based off how it compares to other content in a given section (except for Beginner category), so there will be some variance. For example, the bar is higher in the CPUs, SSDs, and Electronic Components sections, so content beyond the Beginner category will tend to be more technical and/or complex in those sections relative to some others.

If you're not too familiar with a given topic, I suggest holding off on anything in the Intermediate category until you feel comfortable with what is in the Beginner and Beginner/Intermediate categories for a given section.

Note for beginners:

If you're a complete beginner to PC parts (which is unlikely if you are reading this, but hey), I suggest you first introduce yourself to the components of a PC, the peripherals, and some of the different ports and cables there are before you move on to the rest of the post.

Formatting change note

Due to this post's formerly-extreme length (over 10,000 words, and only growing with every addition), I have moved individual sections of the main body of it and the Good Reviewers section offsite separately and linked to each individually. This should make this post much more easier to navigate.

Getting more added to this thread, and expansion.

This post as it stands has reached a point where my own knowledge is a major limitation for future additions to existing sections. That is on top of the already limited appropriate additions where any content necessary for filling gaps is spread across many articles/videos in the form of only tidbits of information, or only in very unfitting sources (as a good example, the GPUs subsection). Not to mention my own ability to notice where additions need to be made, and find more to fitting content to add. Updates will be coming at a slow pace, as they did in the spring and summer of 2017. As such, I need suggestions to keep things going.

If you have a link you want to suggest adding to the post, PM me or leave a comment on the build guide backup linked at the very top of this post with it so I can look at it and decide if it's worth including. Same goes for the complementary thread.

If you have a suggestion for adding an entire section or sub-section to the post, PM me or leave a comment on the build guide backup for me to consider it. Same goes for the complementary thread. Right now in this post I'm only focusing on the hardware sides of things, but I'm willing to consider expanding beyond just that.

This is pretty much the most useful thread on PCPP to date. Perfect for first time builders and experienced builders (like me) who still have alot to learn. This is really good, +1 if I could :)

SilverWolf149 4 points 30 months ago

Throughout the 12+ months I’ve used this website...

When I first read this, I thought that you were leaving PCPP. However as I read(mostly scrolled through it all actually) I realized that you were doing the exact opposite.

Good thing we have this. A central place for information. I hope this can be used and not just lost in all the babble. If it's fine with you, I'll hyperlink this in my profile so people can find some info.

Currently, I have nothing to add to this, except maybe put some links to Youtube channels like LTT, BitWit, and PaulsHardware. Not sure if that's entirely valid for the purpose of this post, but they do do some tests on things and benchmarks, so that might help some people.

SilverWolf149 0 points 30 months ago

Yeah. I just kinda threw that out there as a suggestion as they've become more, well not sure how to put this... too... commercialized. Half of there videos are just random stuff. But Bitwit and Paul do some pretty great things. They pretty much do only reviews or different tests and things like that.

Please don't hate on me.

rhali8 2 Builds 1 point 30 months ago

lol, I was just joking. Linus does have quite a few decent videos with useful information in them :)

All g :D

Good. I can put that away.*

526christian submitter 1 point 30 months ago

If it's fine with you, I'll hyperlink this in my profile so people can find some info.

Go right ahead; it doesn't bother me. The primary intention of the thread was to make information like in the links more easily accessible, so...

LemonComputers 1 point 29 months ago

except maybe put some links to Youtube channels like LTT,

I'd personally skip LTT as they have lots of misinformation.

SilverWolf149 1 point 29 months ago

Yeah, I guess you're right. I now retract that previous statement.
