StarTech 6 inch 4 Pin to 8 Pin EPS Power Adapter with LP4 - F/M

Seeing as my PSU is limited in the cable department i had to purchase a 4 pin to 8 pin adapter to power my PC.

Do i have to connect both the 4 pin and molex cable's to it or is it ok just connecting the molex cable like i have done?.

Actually I think it should be
4 pin Molex from power supply to 4 pin molex on pigtail,
4 pin power supply to 4 pin pigtail
8 pin pigtail to mobo,

I would use both.

DON'T use both connectors. That's not what this is designed for, and connecting both as described above can lead to the destruction of your PSU.


These adapters are intended to be used if you have a PSU that doesn't have an ATX12V 4/8 pin connector and you need one for the motherboard. In these cases, it can be used as a temporary measure until you replace the PSU with a suitable unit that has the requisite connectors. It is connected to the PSU via the molex connector, and then the 4 pin or 8 pin end is plugged into the motherboard as appropriate.

I believe this would have been more suitable: http://www.amazon.co.uk/Akasa-AK-CBP...cp_computers_0

Certainly, if you are going to use the other adapter and are not using the molex connector, be sure to cover over the open end of the connector so that the pins cannot short on anything in your system.

According to the picture in the link, the 4 pin connector will not plug into the motherboard, it is the wrong gender. The only thing that will plug into it is the 4 pin from the power supply.

EDIT: In any case follow the instructions that come with it.

I didn't notice that. Yes, there are adapters that will convert the 4 pin ATX12V to an 8 pin one, and some, like this one, come with a molex connector as well. You should still cover over the end of the unused connector so that it can't short out on anything in your system.

That adapter looks better and less confusing lol.

I'm pretty sure you are supposed to use all the connectors. The 4 pin molex only has two yellow +12v wires coming from the one pin. Look how many are on the 8-pin connector, I'd say at least 4. Hopefully there are some decent instructions included with it.

No, it's an either/or situation. You don't use both.

Sorry, no.

EPS Adapter - LP4 and P4 PSU to EPS motherboard power adapter | StarTech.com

"This reliable EPS adapter combines a P4 power supply connection with an LP4 power supply connection, into a single 8-pin EPS motherboard connector, allowing you to use a non-EPS power supply with a motherboard that requires an EPS power connection."

The adapter is supposed to allow you to connect an ATX12V PSU to an EPS motherboard. It's not intended to adapt an older ATX PSU (without the P4 connector) to an ATX12V or EPS motherboard.

(ATX12V dates to around the year 2000.)

The motherboard is designed to take either a 4 pin or 8 pin +12V connnector. (The last few Asus board I've bought came from the factory with a plastic plug in the EPS socket to make sure that a 4 pin was inserted into the correct side.) I'm not sure that the 8 pin is needed for YTBOY83's CPU, although it looks like it might be a good idea. (125W CPU.)
