Custom built desktop PC: good guides for replacing a power supply?

Thu, 04 Jun 2026 01:32:55 -0700

i did a bunch of research and i am reasonably certain that my power supply (Gamdias Kratos M1 550b) is failing. I’ve bought a replacement (MSI MAG A750GLS PCIE5), and I know that I’ll need to rewire the whole thing—I’ve read you should use all the cables that come with the new power supply. my PC was professionally built, but I am not a professional! I feel I can do it myself but, when I started taking my PC apart, I realized I don’t want to do this without studying up some first. what do you recommend i look at? i saw a few things here, but I don’t know enough to know which products/setups (if any) might be close enough, or which other components are critical to know about. (reading preferred over video, but video guides acceptable). the manual for the product is unhelpful to a regular person.

Also, when I began taking my PC apart, i noticed that the cables were held in place with tiny zipties. as my pc is a mini form factor, i imagine space inside there is quite limited. am i gonna need to invest in some mini zipties if i ever want to close my case again?

HP Compaq 8200 Elite: Did not come with whatever it needed for Wireless Network

Sat, 23 May 2026 16:53:39 -0700

I bought a Pre-Owned HP 800G1 Desktop SFF Fast Gaming PC Win 10 Pro Intel Core i5 AMD RADEON RX 16GB back in 2023. I wanted it because it was cheap and, in my budget, plus it had 2 monitors. When I got my PC, I tried everything to connect it wirelessly to my Wi-Fi. I contacted support and was told it did not have what ever it needed to connect wirelessly and that I could send it back and pay for them to put it in or I could google and find it and put it in myself. Now at this point I cannot even remember if they said it needed a drive or chip. I tried to look it up and I cannot find anything.

When I push the power supply power button the fan comes on. As soon as the button is released, the fan stops. Power supply won't stay on. Installed a new P/S and have the same problem. No idea where to go from here...

Lenovo ThinkCentre: Post beep code is 3 long, 1 short, no solutions found.

Tue, 19 May 2026 20:53:43 -0700

I got a Lenovo ThinkCentre m920q at a Goodwill for $4. After getting a power adapter for it, and disassembling it for curiousity, the power button light and the red thinkcentre light glowed and fan spun. It then beeps 3 times long, then 1 time short. Thinking the problem may be ram, went to microcenter and got a new sodimm ddr4 8gb. Produces same result. The video is with the new stick of ram. Typing anything on a keyboard when it’s on (f1, f2, delete, enter, etc.) does nothing. Any thoughts?
