After my last machine decided to stop functioning properly, somebody recommended that I build my own PC because it is cheaper than buying a prefab, and apparently the process is pretty easy, even easier than building a LEGO set! This is the biggest mistake that I made all season. He convinced me that I could handle it and I failed to handle it.
First of all, I don’t understand why anyone thinks that offering a how-to guide like this one on assembling a computer is a good idea. That is about as reasonable as giving someone a guide on how to fix an engine, as if a Yugo’s engine is identical to a sports car’s (yeah, right). Unless the reader or listener happens to have all of the exact same parts as the author, the guide is next to useless. There is no point.
Computers vary massively in layout and accessories. I hate to state the obvious, but you can’t just toss any fucking how-to guide at a beginner and expect them to understand and follow it perfectly. These guides, much like the official manuals, are dense and loaded with jargon, showing us crap that we don’t have and crap that isn’t where we expect to find it.
Here’s a good example: somebody told me that I needed a large screw to secure a stick. At first I thought that I had to order another part since I lacked that, but it turned out that the screw that I had was just obnoxiously tiny. Almost microscopic. Even my long-distance assistant said that it ‘looked wrong’ when he saw it, but it did the trick.
Likewise, it is ridiculously easy to plug something the wrong way, which can potentially fry your machine. My computer also came with a load of crap that I apparently didn’t need, which is fine for compatibility but ends up making the process more confusing and intimidating.
This hardware is both delicate and expensive to replace, too, which means that if you fuck up, it’s a big deal (unless you’re rich). It was only after I finally took my machine to a technician that I learned that I broke two parts beyond repair, meaning that now I have to spend about $300 on repair and extra parts for a plan that originally cost me $600. I could have purchased a good prefab with all that fucking money!
Look, just don’t tell anybody that assembling a computer is easy, and especially don’t tell beginners to try it without constant, immediate-distance supervision. (Long-distance supervision is still too risky.) The process is so delicate and there are so many ways to make serious mistakes that it isn’t worth it, and anybody who finds a guide or manual unhelpful is going to be very tempted to improvise, which is dangerous. I actually made my fingers bleed trying to assemble a computer (no joke), and I wasted hundreds of dollars that I could have spent on a cheap, prefabricated gaming computer instead. I feel very frustrated tonight, and I am stuck on my smartphone for another week or two.
GPU power doesn’t go through the motherboard because it’s too freaking much power. There are some cards that can be powered just over pcie but I think the limit is 75 watts
wait so where’s mine going then
there’s only one cable attached to it and that’s the display monitor cable
If it’s a low power card it can be powered through the PCI-E slot
On modern graphics cards there’s usually an internal power cable connection from your PC’s power source directly to the graphics card.
but it runs through the motherboard right? like part of the PCB
You don’t have a molex connector on it from the power supply?
no. my PC was built in 2016
Molex isn’t new, my first build in the end of the 00s had them and my card now does too. What card are you using?
Not in any PC i’ve ever built (maybe in some old ones back when graphics cards were way smaller). Idk about laptops though.
how old?
It would have to have been back in the Windows XP days.
Edit: So I looked it up, turns out they do still make GPUs without external power, but it’s the lower end ones. Bottom line: PCIe slots can only deliver 75W, hence why many of the mid tier and pretty much all high end cards now have an additional 6 or 8 pin power connector.
Yeah that’s my point though. Redesign mobos to be able to deliver the 3kW modern cards use
I’m not an expert on the subject but that doesn’t sound like something you’d want to do. Modern graphics cards are just too power hungry. Running high power currents through your motherboard that has fairly sensitive components seems like a bad idea when you can just have a separate power cable to your graphics card that can be as beefy as you need it to be.
You’d also introduce an incredible amount of noise running any sort of supply like that on the board. Interference is a big issue with these denser and denser electronics
Thermally and for the components’ longevity this is not a good plan. RTX xx90 cards can straight up melt the power connector because of the amount of power involved. If that also ruins your motherboard, which has to be more expensive to deliver power to such a GPU, you will no longer think this is a good idea and come back here crying about how your $700 motherboard and $2000 GPU both let out the magic smoke.
