How do I connect my power supply?
Find the main power cable on the power supply (usually the one with the largest plug) and attach it to the long, rectangular port on the motherboard, then attach the secondary power cable to the motherboard. Depending on your power supply and motherboard, you may not have a secondary power cable.
Does the power supply have to be compatible with the motherboard?
In 2019/2020 there is really no issue about compatibility. Over a decade ago, you had 20 pin power supplies and new gen 24 pin motherboards so you had to look out for that. Typically, motherboard – PSU is not a major issue. If both are ATX, the PSU should run the motherboard fine.
How is an ATX power supply connected to the motherboard?
An ATX power supply provides a number of peripheral power connectors and (in modern systems) two connectors for the motherboard: an 8-pin (or 4+4-pin) auxiliary connector providing additional power to the CPU and a main 24-pin power supply connector, an extension of the original 20-pin version.
Which power cable usually connects the power supply to the motherboard?
PC Main power connector (usually called P1): This is the connector that goes to the motherboard to provide it with power. The connector has 20 or 24 pins. One of the pins belongs to the PS-ON wire (it is usually green).
Can a PSU fry a motherboard?
But the more frequent problem for motherboards is power surges. Most power supply units and motherboards adjust their voltages to accommodate small power surges. But if it’s a big one, it can fry your motherboard and all the components connected to it.
Can I use a 4 pin power supply on a 8 pin motherboard?
You can plug a 4 pin 12V cable into an 8 pin motherboard and it will sometimes work properly but other times it won’t work at all or will burn/melt the connector.
Can I use old power supply with new motherboard?
(As some connectors are omitted on old power supplies, this could prevent using an old PSU in your “new” computer.) While modern motherboards accept a 24-pin primary power connection, some old PSUs will only have a 20-pin plug available. If there is also a 4-pin (two by two) connector you should be okay.
How do I connect SATA power cable to power supply?
Use the SATA power connector to plug into the larger SATA slot on your optical drive. The cable can only be inserted in one direction, so don’t force it. If your power supply is older, it may only have Molex (4-pin) connectors. If this is the case, you will need to use a Molex-to-SATA adapter.
Do I need both 8 pin CPU power connector?
If you have more than one 8-pin ATX-12V cable coming from your power supply, you can use either of them to connect to the motherboard. (Some motherboards require two such cables, so both must be used.) You cannot, however, use any 8-pin PCI-E cable to power the motherboard.
Do you need 4 pin CPU power connector?
Distinguished. You do not have to plug that extra 4 pin CPU power connector on the board. The 8 pin is more than enough for running the system. You’re totally fine without it.
Where does SATA cable go on motherboard?
SATA uses simple cables that are keyed to fit on the drive and motherboard connector one way. Connect one end of the SATA cable to the drive, and the other end to an available SATA port on your motherboard, and you’re halfway there.
What is the 4 pin CPU power connector for?
A 4 pin eps connector on a motherboard is used to give added power to high end processors and to support high power draw pcie x16 devices. I7-7700K, for example could draw more power even though it can not be overclocked on your motherboard.
What is the P2 connector on a motherboard?
The P2 is a 6-pin connection that uses 4-pins (the other 2 are blank). I’m trying to find a pin diagram for this P2 connection so I can make an adapter to plug into the standard ATX 24-pin from the psu. Tags (2)Mar 16, 2017.
What cables come with power supply?
Most PSU’s provide two cables; one with 4-pins and one with 8-pins. Obviously you only need to use one of these cables. It is also possible that your 8-pin cable can be split into two segments to provide backwards compatibility with cheaper motherboards.
Can motherboard fry RAM?
Yes of course it can. The motherboard regulates current and voltage going to the RAM and CPU.
Is it OK to touch a motherboard?
There is no problem with touching a motherboard with bared hands or anything unless you or the thing you are touching have static electricity because that can cause a lot of damage to your motherboard and other pc components.
How do you tell if a PSU is fried?
Symptoms of a failing computer power supply Random computer crashes. Random blue screen crashes. Extra noise coming from the PC case. Recurring failure of PC components. PC won’t start but your case fans spin.
Do motherboards need 8 pin?
The 8 pin power connector you need for the graphics board comes from your power supply, not the motherboard. Your powet supply should have various power connectors.
Does motherboard need 8 pin?
Depending on the CPU you’re using, that may be sufficient, or it might throttle. If you’re planning on Overclocking, you’ll need the full 8-pins. If your CPU has 6+2 pin connectors, DO NOT try and force one of those into the motherboard.
Can you use a 6 pin on a 8 pin motherboard?
No, the 6+2 pin is for pcie supplementary power, it’s for GPU power basically the 8 pin on the mobo is for cpu power. Your power supply should have either a 4+4pin or a 4pin for cpu power, use that.
