My brother has a motherboard with several PCI-E x1 slots. He currently has a 4850 hooked up that he uses exclusively. If I hook up one or more GPUs on the same board and use them at full load with Bitcoin, will it affect his video performance on his 4850 in any way? This is assuming I can pick and choose what video devices I want Bitcoin to generate on. Can I?

In addition, will a quality 500W dual-rail OCZ power supply be able to support a dual-core CPU (E8200), a 4850 and a 5770?

Thank you.

To my understanding, most manufacturers underrate their power supplies and overrate the wattage requirement of their GPUs. Your mileage may vary.

I am very new to the Bitcoin community so I can't comment on your question but his options for PCI-E x1 gpu's are very limited and low preforming http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&N=100007709%20600007854&IsNodeId=1&name=PCI%20Express%20x1

PCI-E x16 cards can be used in PC-E x1 slots with negligible performance loss for BTC mining. Gaming might be a different story. However, I don't play games. : P

True, but the connector must be the right size - and cards used for mining on the market use a physical x16 connector.

A cut at the end of the slot does the trick. There's a thread down below discussing this.

If you feel safe hacking the slot and having little retention for something with more weight than what is typically in an x1 slot, go for it ;)
