Hi I’m Allen and welcome to Expert Village.
Today, I’m going to show you how to build your very own personal computer. This right
here, power supply, you’re going to need this operating your system. Now this power supply
is just a basic ATX power supply, one of the original ones. So you’ll see only a few connections
on here, this connects to my ATX board. The newer power supplies actually have the ATX
connection and it’s called like a 12 volt power rail, it’s another safety connection
that they use to make sure you don’t short things out. Here you have your normal drive
connectors, this connector right here and your floppy drive connectors, the newer ones
also have the SATA connectors which are little flimsy so be careful when you’re plugging
those in. Now the biggest thing there are a lot of brands out there for power supplies
so do some research on them. I’ve seen ones from Flower to Pow-Max to a lot of Chinese
import brands so definitely do your research depending on what you want to spend and make
sure that the power, not consumption, but the power flow is, you know constant and everything,
it has a constant power output you don’t want too much fluctuation, or you really don’t
want any and all. And also when you look at these power supplies, you have to know the
wattage and my recommendation is pretty much anywhere from 400 and above depending upon
what you want to do. I stick with around 600 Watts and that way I can expand my system
but 400 really should be good if you’re running just a basic system, you know one drive, a
hard drive in a CD drive and a couple components. 400 should really get you by, but if you really
just you know want to spend the extra couple dollars then go 500 and up and you should
really be fine. There is ones out there that have a thousand Watts, so I don’t know what
these people are running in their systems, but you know maybe something to do. Some of
the companies I recommend, Cooler-Master makes some good drives, or power supplies I’m sorry,
and also I use a company Ultra, they have a lot of power supplies out there, I haven’t
had any problems with them, they have really good rebates that you can find almost on all
the sites. So check it out, this is definitely an essential part of your computer. The power
supply or the PSU as you can always type it in online and find out more information. So
right here this is a power supply, an essential part to building your own personal computer.

    I also agree, Corsair and Antec are both good, but the Corsair tx650 is fairly cheap, and it has more power.

    Only problem, it isn't as earth-friendly like the Antec Earthwatts.

    FORGET about an upgrade. If it's a slimline, it's a small form factor; there's no way to upgrade the power supply.

    Check the wattage you have, search around for cards that will use something around a quarter or so of that wattage rating, and make sure it doesn't need to be plugged into the power supply directly.

    do you need a power supply?

  • October 26, 2010 at 10:55 pm

    @MrNcoppick Of course how would it work without one? Always buy a good quality one (Seasonic, Antec, Corsair) and check for reviews with riple and load test (two good websites are Hardware Secrets and JohnyGuru. And Cooler Master and Ultra are crap units.

    lets say my current PSU max wattage is 300 can i buy a new one with ike 500 Watts?

  • October 24, 2011 at 10:00 pm

    @GamingTheFilms Of course you can! You can always get a PSU with more wattage. If it's rated at at 500W max it doesn't mean it always uses 500W, it just means it can support up to 500W. It will provide power as it is needed. It's always better to have more power than not enough power.
