Power supply requirement for Nvidia Geforce 7900 G
Hello all. I just purchased 2 MSI nvidia geforce 7900 GS PCI-E video
cards that I intend to use in SLI mode in replacement of my current nvidia geforce 6800 GS PCI-E in SLI mode. the geforce 6800 GS don't require external power but the geforce 7900 GS cards do. My current power supply is a PC Power & Cooling Turbo cool 510XE 510 Watts (650 watts total) which I think is the best power supply in it's class. It is not a SLI power supply, it has only one PCI-E Power connector but I have a molex drive wye PCI-E connector for a second card for SLI. I don't know whether or not my current power supply is enough. I'm eyeing another pc power & cooling power supply, the SILENCER® 750 EPS12V 750 watt PSU which is a SLI certified PSU. So I need to know whether or not my current PSU will be suffiicient. Give me your suggestions and comments. Here is my current computer configuration.

The 7900GT uses only 48W peak. The 7900GS is similar. The PC P&C 510 is more than enough to power two of them. BTW, if clean wire layout is important to you, in lieu of the Y-adapter, there are single 4- to 6-pin adapters available: http://www.us.ncix.com/products/index.php?sku=17110 -- "War is the continuation of politics by other means.
