I just posted this link in another topic regarding PSU’s, it might be useful to you too,
It calculates the amount of watts your computer needs at the least, your card might need a 300 watts according to the manual but other components also use their share of wattage, summing everything up might make your powersupply insufficient after all.
Well, now I’m starting to think it might be the power supply.
I had the video card AND two fans connected to the PSU all on one bundle (not sure what you call it). I disconnected both fans and with the door off tried the King Kong demo again, this time with the GPU havin dedicated access.
Interestingly, the King Kong demo, which would NOT run for more than a minute before, now runs…and looks nice I might add. However, I can see some slow down and “hiccup” when the action gets heavy. But it stayed on this time.
Sadly, I tried Doom 3 and nada. It’ll install the game, but within a minute it’ll auto reboot.
Like I mentioned, I bought a PCP&C Silencer 360 based on Gigabytes online recommendation of a minimum of 300 watts. I figured the extra 60 and the quality of the manufacturer would mean I’d be okay. Now I’m thinking maybe the rail voltage is low or maybe Gigabyte has woefullly underestimated power requirements.
I’m STILL not sure if this is the case, but it IS intersting that the Kong demo would run at all.
Anyone have any thoughts? Would be interested in the PSU ratings of other 7600 series owners are using.
I was planing to go 7600 from my 5500 as well… damn. I hope you find a solution, Tom71!
By the way, I don’t know if it helps, but maybe try and disable FastWrites in BIOS (if 7600 has FastWrites), cause that helped me once to get rid of some nasty restarts and BSODs.
Edit: I just recalled that the 7600 is natively a PCI-E card and those AGP versions have a AGP birdge on them. The review I read said that people would be worried about this fact (instability, incompatibility):
The card we received is working at the stock clock speeds. Like the GeForce 6 AGP series and the GeForce 7800GS, it uses the HSI PCI Express to AGP bridge. These GPUs were made natively to PCI Express. To avoid extra costs they are just buying the HSI Bridge and using it. It’s only working with AGP X4/X8 (1.5v/0.8v). Over time, there have been many claims appear that the HSI Bridge is a troublemaker. But, during this review, we didn’t notice any issues with it. Here’s the full review over at ngohq.com.
how much is actually being used on the system? plus, my power supply is RATED 500 watts, but has 18 amps and i think one 12V rail. Its a cheap one, thats why, but I can’t be arsed upgrading it because it works jsut fine without an expensive one, i`ll replace if i need lol anyhoo, what I’m saying is, a 350 Watt from Enermax/Tagan/Ultra any high end name etc. would beat a Rated 550 Watt from an unknown make at a surprisingly low price
