Power supply to run a 256mb 7800GS AGP?
I have a Thermaltake TR2 430W.
I am considering getting another hard drive, and a 7800GS AGP card. Will this power supply handle all of this? My "old" AGP system: P4 2.53 1 gig ram Plextor PX 716A ATI 9800pro--to be replaced Seagate Barricuda 80g SATA HD---to add another one TB Santa Cruz soundcard Thanks -- ~~SHRED |

| Thanks. | I had heard some rumors that a 500W power supply was needed for the 7800GS. You could probably get by with a 300 Watt power supply. Your 430 Watt power supply is more than sufficient - you could add three or four more drives with no trouble. The maximum power consumption of an 80 GByte hard drive is less than 20 Watts, and that is only when spinning up. Larger capacity drives usually don't use any more power because the capacity increase comes mostly from higher recording density, not heavier platters. A sound card use very little power, a few watts. Your CPU uses only 70 or 80 Watts (some is lost in the DC-DC down conversion from 12 volts to ~ 1.5 volts. Swapping out for a 7800 GS will only add 40 Watts or less to the system power consumption.

Although if overclocking or upgrading to a faster CPU are possibilities, that 70 or 80W can easily soar well over 100W. Same goes (to a lesser extent) if you'll be overclocking your 7800GS. |

I wouldn't count on 300 working, but certainly a 430 Watt supply is more than sufficient for anything that the original owner's motherboard will accept. Here are the URLs for two marvelous articles written by a guy who actually MEASURED the power consumption of nVidia and ATI video cards at standard and overclocked speeds. It doesn't have the nVidia 7xxx series, but it is still good to actually know the power video cards draw. I hope Tim Tscheblockov, the author of the articles does an update. http://www.xbitlabs.com/articles/video/display/ati-powercons_8.html http://www.xbitlabs.com/articles/video/display/ati-vs-nv-power.html Phil Weldon "Mark M" wrote in message k.net... | "Phil Weldon" wrote in message k.net... | 'SHRED' wrote: | | Thanks. | | I had heard some rumors that a 500W power supply was needed for the | 7800GS. | | You could probably get by with a 300 Watt power supply.
