4pin 12V Power

[geoffgarcia]

Hey there, sorry to bug you all with such a basic question but I'm having a problem connecting a newly purchased power supply and think I may have purchased the wrong part, but before I buy a new one I'd like to be certain of what it is that I need.

Currently I'm using an Antec Basiq 350 on an Asus K8V SE Deluxe motherboard.

I've upgraded my video card (to a 3850 HD) and wanted to upgrade my powersupply to something over 450.

I purchased a TruePower 2.0 model: TP2-550EPS12V.

When I was attempting to install it I noticed that it doesn't appear to have a 4pin 12v power connector.

The motherboard I'm using is a 20pin version and it has 4 additional pins on the other side of the board. However the 4 pin port doesn't match the additional 4 pins on the 20/4 connector from the power supply.

The power supply does have an 8 pin connector which can be split into 2x4pins which have the same alignment as my motherboard 4 pin connector, however attempts to use either of these 4 pinners didn't do anything.

Does that make sense?
What is the name for this 12v connector that I need so I can be certain my next power supply is appropriate?
Also, any recommendations on a powersupply that does have it and is over 450?
Any info would help!
Thanks very much.
Geoff

4 pins from the 20+4 connector should be left unconnected. You need to use a 4 pin ATX12V in that connector - it has two black wires and two yellow wires. In some cases (I can't immediately recall if this is the case with the TPII-550), the 8 pin connector splits into two 4 pin connectors, one of which needs to be used. Try both halves as they are keyed differently.

That PSU should definitely work with your board.

I looked at the home page for the power supply you bought and here is a quote

"EPS12V 2.2 compliant/ATX12V 2.01 compatible. 24-pin main power connector with detachable 4-pin section
8-pin +12V connector with detachable 4-pin section for universal motherboard compatibility"

I don't see what the problem would be. Your motherboard had a 20 pin power connector so you'll have to detach the 4 pin extra section from that. Plug in the 20 pin section.

It also has a 8 pin power connector on the Power supply. Youll have to make that two 4 pin sections and plug one of thoes into the 4 pin connection on your motherboard.

After that it should work fine. The power supply is made this way for all motherboards to use.
