Hey guys, I know this may sound dumb. But I want to know how to connect the two power connectors with graphics card into my Acer Aspire ATC 105 desktop. The graphics card that I'm going to put is Radeon hd7770 and my desktop has PCI E x16 slot.
Can someone please give me an answer?

First off the recommended power supply for a 7770 is 500W. Granted you can probably get away with less, but that system only has a stock 300W PSU. You may want to be caution installing that card.

The adapter you are referring to is a (2) 4 pin molex to 6 pin PCI-E adapter. You will need to plug it into 2 free 4 pin molex cables and then into your card. However, I also know that a lot of OEM power supplies no longer come with Molex connectors and sometimes very few extra power connectors at all.

You are almost better off with a GTX750 that has no PCI-E power connector and a required minimum 300W PSU.

So should I buy a power supply seperately? I'm thinking of buying this one. Go to link

I really want to install the radeon hd 7770 to my Acer desktop because I already bought it a long time ago.
If I install my graphics card into the 300w power supply, will the motherboard malfunction or anything?
