Help needed? CPU and Mobo

[MrPizza0021]

my current i3 7100t does not have a 8-pin connector on the motherboard because it's in a HP Slimline and so I was wondering if upgrading to a new motherboard that has the 8-pin does   it need the 8-pin connected for it to work?

an 8 pin cable can be split into 4+4 if it doesnt you can plug it in anyway,

 

my understanding is you can plug a 4 pin into an 8 pin and it will still work like so:

And the best part is the motherboard usually doesn't care which 4 of the 8 you use

I know this, but my psu doesn't have either. But my current PC setup stock HP Slimline doesn't have a connector on the Mobo so it doesn't need one to run. So do I need one to run the couch in a different Mobo?

If your PSU doesnt have either get a new PSU honestly, you can find adapters on ebay though.

 

Your HP WILL have one but it will be a special HP connector.

Sorry I was in such a rush I didn't even notice it has the four pin. Thanks for the help. So it should work just fine with only four?

if its a standard ATX 4 pin it will work, if its a special size it wont.

Yes it is standard.However, won't this only give the cpu half the power it needs?

nope it will give plenty of power, you just wont be able to overclock an i5 or an i7 on it.

Okay thanks for the help.

More than enough for your i3.

So if I have to get an adapter without getting a new psu will this connector work? Why does this molex connector only have three pins?

that will be less power than the 4 pin if you need an adapter you need one that goes from your existing HP connector to 4pin ATX

I looked it up and someone on tedshardware said that molex pushed the full 12v through only two of the pins. So I was wondering if that isn't true will this still work?

its now about voltage, its about wattage, many psus have multiple power rails, which means that molex lines wont be able to pull enough power for a cpu.

[MrPizza0021]

Either way though it should work just fine with four if the 8 because the current Mobo inly has a 4 pin and it is running the couch from the factory.

I Wass also worried about that. Didn't think molex was would have enough power.
