Thanks a lot for taking the time to explain us beginners in electronics the basic concepts of how a power supply works. Your efforts are appreciated. Good Video.

@RagnisArmus Having multiple leads allows more power to be carried with minimal line loss (resistance which drops the voltage). This is why newer EPS12V connections have 4 12v lines and 4 grounds.

is bestec a good manufacturer?
TheUrzur 2 weeks ago
@TheUrzur They're okay... they're built fairly well, but the newest ones that I have seen are using Teapo and Capxon capacitors. I have seen several fairly new Bestecs in non-working condition due to these capacitors failing. Definitely stay away from the old ATX-250-12E eMachines power supplies because they have faulty 5vsb rails that have been known to kill motherboards.

How can you determin wattage of a Power supply when it's origanal metal case has been discarded?
MrLookeyLew 3 months ago
@MrLookeyLew Look for model numbers on the PCB, though in some cases, many manufacturers use the same PCB for different wattage models, so it can be difficult.

I noticed you didnt cover additional auxillary 3pin connectors and 6pin motherboard or PCIe connectors. Thanks! Great Video!

@MrLookeyLew I missed these by mistake, though you'll only find these getting used in high end systems with graphics cards that require the needed power.
