I just installed this card on a Silverstone Nightjar 300W Powersupply.
The rest of my specifications are:
1x SLK3700B + AcoustiPack
1x AsRock 4Core1333-FullHD
1x DualCore Intel Core 2 Duo E4400
2x 2GB OPC Reaper HPC DDR2 memory
2x 250GB Seagate Barracuda SATA HDDs
1x Samsung 1TB Sata HDD
1x LG DVD
2x Cooltek 140mm fans
2x Nexus 120mm fans
1x Schyte 90mm fan
I havent tried much yet, because I just recently installed the GPU.
I did try running [email protected]
and [email protected]
on the CPU while looping 3DMark06 a couple of times, just to see if how my PSU and the rest of the computer could handle it. Temps and so on... No problems so far!
About 80 degree on graphic card and 45-50 on CPU. One of the 140mm fans blow at the GPU at a slow speed.
It was fanless at first when I heard a weird squeling noise.. When I was tried to locate the source of the noise, the temprature on the GPU raised without I noticed it. It climbed to 110 degree celcius and the computer beeped and selfterminated as a precaution...
So.. Dont run it without some kind of air circulation or something!
This was the source of the noise:
An annoying sound from the PSU when VSync is disabled in some 3D applications... I found a workaround with ATI Tray Tool.
For now it looks like its working out fine running this card on a 300W PSU.
About video tearing, perhaps you need to tick the "Tripple Buffering" on OpenGL in Catalyst Control Center or something?
