How to Install a Power Supply into a Desktop PC

This is a full-on fleshed-out how-to video on installing a PSU in a PC. It’s not gonna be a short one, just warning you off-the-bat, but basically it’s all the ins and outs of a power supply, what you need to know, what every cable is meant for and what goes where. It’s actually very simple if you’re new to it.

Please do not ask me what kind of PSU your PC should have, look up the specs of the parts you’re getting and go from there; there’s simply too much information to know beforehand and I cannot respond to every single comment with vital information. Thank you.

I found a 600 watt evga power supply for 50% off at best buy, one $30, took a drop from $60

nickr1125 says:

Thanks this was really helpful! And on a side note you should never have an issue buying a bigger power supply then you need, it’s actually a lot better and something you should do

Malik Walters says:

Can’t you just take out the plugs in the old power supply and plug those into the new one? So its easier?

Dominic Commisso says:

Maybe 350 400 450 500 550 650. Got it. I’ll go get all of those.

Thank you! You saved my life.

I know this video is almost 3 years ago but I’m still hoping for some answers. My CPU wasn’t powering up but there’s a green tiny light on the mother board. So I began fumbling my CPU and I accidentaly fried my Power Supply and the green tiny light went out. So I bought a new PSU but I’m not really sure if my mother board is still okay. And I don’t know any person who can help me

Can you tell us how to install all the motherboard to hardware cords? So basically data cables to drives and graphics cards.

About to install a 500wat PSU and I have a gt1030 video card

TS Games says:

Hi, does anyone know if for the fans you need to buy an additional connector? Or does it come with the new PSU usually? Got one coming today and everything seems simple except the fan part, thanks in advance.

Wave Cannon says:

Yulee says:

DIRECT BaNaNa says:

I’m getting a 1070 for my build would u recommend a 550 psu or 650 psu

Caden Herren says:

You shouldn’t do thsi in carpet

Col7777 says:

I always think if they thought ahead when making power packs, if they made a standard connector to the actual power supply then if it failed just unplug that and all the other cables wouldn’t need to be removed… but they didn’t lol.
