[quote="Ashley":2ga1vixd]It might be badly installed to the case, a loose screw could make it buzz. Maybe tightening everything up would fix it. Did you install it yourself?[/quote:2ga1vixd]
Yes, but at the moment. it's not actually botled to the case, it's sitting outside it, so it's not that unless it's a component inside the psu itself. Also, the problem goes away if I take out the 9800GT - so it seems like it only happens when the PSU is running above a certain power draw.
[quote="Ashley":2ga1vixd]If the wattage is sufficient don't be fooled in to thinking higher wattage equals more quality - you should get the lowest wattage that covers your computer, then find a good model. Once I bought an el cheapo PSU and it exploded after six months. 500W should be more than enough for most desktops if you actually calculate the peak power consumption.[/quote:2ga1vixd]
I read on a lot of websites that Seasonic makes quality stuff, so that shouldn't be it - it might just be the one I've got.
[quote="SoldjahBoy":2ga1vixd]How many 12v rails does the PSU have?[/quote:2ga1vixd]
I have no idea. I can't find it anywhere, and as much as I've tried to understand this whole amps/rails thing, it doesn't make much sense, because it isn't clearly labeled anywhere. Is this it?
I read something about you're supposed to add the amps, so that should be enough, right? The card wants 26amps/400watts. I'm wondering since taking out the 9800GT stops the buzzing if I should get like a 700w one.
Thanks for the help, everyone!
Edit after above edit: Yeah, returning it sounds like a good idea. If the replacement still buzzes I'll opt for a higher wattage.
