Power Supply - Understanding all the Power Supply Connectors in your PC — Transcript

Full transcript

1. 0:00On a daily basis I'm asked where does this  connection go what is this connection do I
2. 0:05really need to connect this connection well in  this video I'm going to help you figure all of
3. 0:09that out let's get started newer and slightly  more expensive power supplies are modular.
4. 0:15Modular meaning you don't need to have all of  these cables connected if you don't need them
5. 0:20for example if you only have one SATA drive  just disconnect this cable put it inside of
6. 0:27the power supply box and set it aside for  later in case you need it at whatever point
7. 0:33so you don't need all these cables older or  generally cheaper power supplies cheaper as
8. 0:39in less expensive and many times less quality are  not modular meaning all of these cables they're
9. 0:45going to stay attached to the power supply and  you can't remove them so with those all of these
10. 0:50cables if you do or don't know what they are  we're going to go over them real quick and I'm
11. 0:55going to show you what every single cable  is so starting off with the largest cable
12. 1:01the 24 pin ATX cable this one is going  to go on your motherboard and is going
13. 1:08to supply power to your overall motherboard  and so with this little clip over here you'll
14. 1:14generally find a little lip on the side of  that ATX connection and that they'll tell
15. 1:20you that that clip goes right over here  so you can just connect it right here
16. 1:31and push it down
17. 1:35this pops up a little bit to lock in place so  you just can't pull it out in order to take it
18. 1:40out just push this up here down you'll notice  that went up and now you can more easily remove
19. 1:46it more easily because it's still very difficult  to remove so that was the ATX24 pin on here on the
20. 1:54top of the motherboard typically above the CPU  it would generally be right up here though it
21. 2:00can be in different places just like the ATX24  pin we'll find the 8-pin EPS or the 4-pin CPU
22. 2:08power now not all motherboards are going to  have both generally they're going to have the
23. 2:13EPS 8 Pin some other boards might have two EPS  eight pins and some might only have a 4 pin now
24. 2:20the eight pins are generally for overclocking as  they provide up to 235 watts of power and the 4
25. 2:27pin generally for older CPUs and low wattage CPUs  will only provide up to 155 Watts that being said
26. 2:36if you have a board that has two generally it  is for overclocking the second EPS connection
27. 2:43as the 8 Pin can handle most of it on its own so  in this case you would only need the eight pin
28. 2:49now if you're going to be hardcore overclocking  where your CPU will require more power you might
29. 2:54benefit from using both the 8 Pin and the 4 pin  or the 8-pin and another 8-pin whichever you might
30. 3:00have now some of them will have a straight  8-pin EPS connection that looks very similar
31. 3:07to a straight eight pin PCIE connection this is  for video cards and we'll get to this in a second
32. 3:14now there is a four plus four or an 8-pin EPS CPU  power then there is an 8-pin PCIE power for the
33. 3:27graphics card now the a pin for the graphics card  can either be a straight 8 or a six plus two a six
34. 3:35plus two will never work on an EPS connection  you can force it if you pushed incredibly hard
35. 3:42but then if you notice these little patterns right  over here if we're looking at the CPU power the 8
36. 3:48Pin there is a little box here and a little box  here but it has the Tilt up here and up here as
37. 3:54well as here as here then there's another one  right over here that has a little tilt up there
38. 3:59as well the rest are square now if you notice on  the 6 plus 2 which is GPU power for the graphics
39. 4:07card you'll notice it does have this little tilt  right up here but it doesn't have that same tilt
40. 4:13right here which should be right over here the  six plus two won't fit in the EPS 8 Pin unless you
41. 4:21force it in there which I have seen it done you  have to push incredibly hard and then of course
42. 4:25you will warp the plastic for the four plus four  or the eight pin which is an EPS connection that
43. 4:32is going to go easily right into here so we'll  just join them now when you join them notice
44. 4:37there is a little connector right over here,  here to let you know that this is how it goes
45. 4:44not this way so then and mind you they're  different for every single power supply but
46. 4:49for this particular one we can just slide it like  that now it is connected now like we had for the
47. 4:5524 pin this little lever right over here that you  can push with your finger is going to lock right
48. 5:03into these little notches right over here and then  we can just push that right into there and it will
49. 5:13lock in place so that we can't just pull it  out to take it out we need to push this down
50. 5:21and then pull up now older hard drives
51. 5:25ran off of four pin Molex and that's IDE we  won't go over that here and Molex looks like this
52. 5:34it's generally not used anymore but it  will be on a few devices now with Molex
53. 5:41you'll notice there's a little curve right up  here and a little curve right up here it's not
54. 5:46just a rectangle and that is going to be evident  right over here and over here on the drive and
55. 5:54generally it fits in easily now unfortunately with  Molex it was not the best because the housing came
56. 6:05loose very often and so you notice those pins  move around a lot and it caused a lot of issues
57. 6:13so newer drives are only SATA power you  can see that right here now SATA power
58. 6:19is a much nicer connection it's just  a flat connection like this there's
59. 6:24a little tiny L right over here and  you can just slide that right in here
60. 6:34and that's it you've connected  that connection and unlike Molex
61. 6:40none of these cables move around now  in between drives still had that Molex
62. 6:45and that side of power though you didn't  need to connect both you either connected
63. 6:49Molex and the SATA data cable or the set  of power and the SATA data cable not both
64. 6:58so again that was SATA power they're generally  in a strand probably about three or four
65. 7:07and Molex this one really isn't used much and they  generally come in three or four as well on that
66. 7:15same cable not all of them there is generally  a four pin floppy connection now these really
67. 7:22aren't used anymore and actually I don't have any  devices easily attainable so that I could show you
68. 7:27that older PCI sound cards PCI not PCIE needed  these newer USB or firewire cards which firewire
69. 7:36really isn't used anymore but newer USB 3.0 or  3.1 or USB type-c cards may still need it because
70. 7:44they may need additional power than the PCIE slot  can provide because of course you want to plug in
71. 7:50multiple USB devices some might still need this  but these were typically for 3.5 inch or five and
72. 7:57a quarter floppy drives again this isn't generally  used anymore on that same Molex connection
73. 8:06or old DVD or CD drives or you plug those in  here these were generally either IDE or SATA
74. 8:16again these aren't used much anymore  and for the biggie the PCIE cable this
75. 8:25will be either a 6 pin which is also a 6  plus 2 pin that can be used as a six pin
76. 8:33or when lined up correctly can also be  used as an eight pin and that is generally
77. 8:43for graphics cards or video cards  whatever you want to call them
78. 8:50and for this particular card we need an eight pin
79. 8:58so we joined that 6 plus 2
80. 9:04and then we'd connect it just  like that and like the other
81. 9:08cables when we want to remove them  just push it down and pull it out
82. 9:16now more power hungry cards
83. 9:19require more power this one for example the  7900 XT requires two eight pins now some cables
84. 9:30for PCIE have Daisy chains that is one cable that  branches out to another I never recommend these or
85. 9:38I used to back in the day when cards weren't so  power hungry but I don't recommend these because
86. 9:42they don't generally provide enough power so  while this will fit just putting that over
87. 9:48here I don't recommend it even though this has two  what I recommend is grabbing a second cable using
88. 9:54one from this cable and then one from this cable  so you have extra hanging out but you can always
89. 10:01zip tie that to make it look nice and then just  connect it like we did before and the same goes
90. 10:06for video cards that require three connections  or four connections or however many it may be I
91. 10:12don't recommend daisy chaining them if anything I  recommend a new power supply but you want to make
92. 10:17sure with the specifications on the video card  the latest to power supplies is the 12 volt high
93. 10:23power connection this guy right over here also  known as 12 VHPWR now this one comes out to four
94. 10:31PCIE cables just like we talked about a little  bit earlier and from four it comes out to this
95. 10:39single connection right here that connects right  into here into the video card and it just recently
96. 10:47came out and Nvidia and Sig are having their own  fair share of issues supposedly there's a new
97. 10:52one in the works as we speak so then connecting  over here you would use this piece right up here
98. 10:59and that would connect right up here and that  little teeny tiny click happens right down here
99. 11:08right here you'll notice there's a  little lip and when you click it in
100. 11:19it clicks in right there and to remove it  like with the other ones push down here
101. 11:28and just pull it out if you're new to building PCS  you have no idea what these cables are and that's
102. 11:34okay or maybe you're an older Builder and you're  coming back to building a new PC after 10 years
103. 11:39and you don't know what any of these cables are  that's okay too I'm here to help you on this and
