Hi,

I'm buying a new PC and it has been ordered and shipped. I am quite inexperienced when it comes to computer hardware but I have some friends help me piece it together. Today while reviewing the parts, we discovered that the PSU uses a 4 pin connector while the motherboard has an 8 pin slot. My friends can't agree weather it will still work or not.

This is the PSU

this is the MB

Anyone know weather they will work ok together or do I need to get a new PSU?

The 4-pin connector will work just fine. When you get the components take a close look at page 24 in the motherboard owners manual. It describes how to properly connect the CPU power connector when your PSU only has a 2x2 12v connector. The manual is also available online.

Here's a quote from the manual:

"The power connectors are compatible with power supplies with 2x2 12V and 2x10 power connectors. When using a power supply providing a 2x4 12V and a 2x12 power connector, remove the protective covers from the 12V power connector and the main power connector on the motherboard. Do not insert the power supply cables into pins under the protective covers when using a power supply providing a 2x2 12V and a 2x10 power connector."

The last sentence is what applies to you. The diagram further down the page shows what pins to use when using a 4-pin connector. You use pins 3, 4, 7, & 8 which are the pins on the bottom closest to the CPU socket.

Yes it probably will work, alltho usually when there is an 8pin slot it is preferrable to use an 8pin connector.
If you do get another PSU, which depending on the other hardware you have might be advisable considering that it is not a known good quality PSU.
Known good brands include: Antec, Corsair, Seasonic, OCZ, Silverstone, BFG, FSP, Zalman, Thermaltake (Toughpower), Cooler Master.
