I have a o.b 1900xt and I'm getting very low frame rates when i installed Catalyst 7.10.
but when installed 7.8 the framerates increased. i was wondering, having not enough power
from the psu could cause poor frame rates? my psu 350 watt

edit------------- i got it today, hoping to resolve my problem b4 my 15-days./

More about : x1900xt openbox eehhh

For the x1900xt they recommend at least 30A on the 12V rail.

System Requirements:
PCI Express based PC is required with one x16 lane graphics slot available on the motherboard.
Connection to the system power supply is required: 450-Watt power supply or greater, 30 Amps on 12 volt rail recommended (assumes fully loaded system)
PCI Express compliant power supply required. Connect directly to the power supply with a 6 pin PCI Express power connector For CrossFire: 550 watt power supply or greater, 38 Amps on 12 volt rail
Installation software requires CD-ROM drive
DVD playback requires DVD drive and decoder software (not included)

rhe power supply that you have chosen is only 18A on the 12V rail. That Jpac is really not recommended (tier 5) get A power supply with at least 30A on the 12V rail, Tier 2 or 3 from this list.

Id uninstall it, cause at boot it draws alot. It could bring your whole system down. I have a 29 amp (both 12v rails/combined) with a 1900xt. It runs fine. 2gigs ram, a dvd read write and 1 HDD. Its a enermax. 350 just wont cut it

I run a Corsair HX620 with an X1950 Pro card with the same power requirements as yours. The HX620 is 50a across three 12v rails. That's more than I need but I'll be using it with my next build as well. Their 5 year warranty is unbeatable and I'm sure they'll still be around in 5 years. They're expensive, but you definitely get what you pay for in a PSU. You might consider one of the smaller models if you don't plan on ever using it for more than one video card.

These are good deals:
