Installed it, but it makes the strange buzzing noise.

According to the manual, it says that this is due to the motherboard not able to load it.

Whats wrong with it?
 
Then again some are very expensive. im guessing you'll have to get one with the i think 6 prong plug too. You'll have to make sure the power supply has the plugs you need for the motherboard and video card.
 
hmm depending on your cpu and if you overclock or not you will need a 550 and would probably be better off getting a 650 watt psu. Yeah if the card has no power hookup then it does some weird stuff.:p

also dont be too stingy with buying one. Dont save an extra 20 bucks to get some crappy brand power supply. Go ahead and get a good one like corsair or thermaltake. PSU's are important, if a problem occurs and your power supply fails if could cost you a new computer.
 
Blue Stealth is right on with this one. I know we've discussed PSUs several times in this folder, but to sum up:

1. Get at least a 650 watt PSU. It'll be able to handle most of what you could throw at it in the next few years without being TOO overkill.

2. Go with a recognized name brand: OCZ, PC Power and Cooling, Antec, and Thermaltake are four well known names.

3. DO NOT GO CHEAP! A cheap PSU usually does not give you the power it states on the side in real life situation. Also, they tend to give you "dirty" power. This will lead to a much shorter lifespan of your hardware, and lots of troubleshooting nightmares down the road.
 
I did some research because I just got an 8800GT. I wasn't able to find any specs specific to my card, but a comparable BFG card listed at least a 425W power supply with 28A on the 12V rail. My power supply is 500W with 28A on the 12V. It has been running solid for the past week, even when gaming (Crysis, TF2, Portal, etc.).

You don't need a 1000W power supply...somewhere around 500W should do, but make sure the 12V rail has the amps you need. Like I said, 28A was recommended for my card. It can't hurt to get a bigger power supply however. Your computer will only use what is necessary to power the components in the tower. I agree with Tykael though; you are probably better off spending the extra $20 or so on a decent power supply. The cheap ones tend to cause more problems than they solve.

I see people spending like $200 on a power supply these days. I think that's absurd, but I'll spend $50-$60 instead of $20 on a cheap-o that's supposed to be the same.

yeah just to blow your guys minds I ran my quad core Q6600, my evga 680i mobo, and my 8800GTS 640mb on an antec 350 Watt power supply for about a month until my new one arrived here in saudi. no problems, but dont do this, I did a lot of figuring before I turned it on and ran the thing under that wattage. Really with an 8000 series card you can get away with a 450 watt psu, but you might as well get something with more watts for the protection and since bigger, more power hungry hardware is bound to be released as computers get better.
 
Corsair is another great proven brand. You can easily get away with a 520 or 620W (I have the 620 and swear by it) modular or 550/ 650. If I remember correctly, these are Seasonic PSUs, the same company who makes most PCP&C.

You don't need high wattage if you have a quality PSU that isn't rated by max load like many cheap brands. I overclock hard with a lot of extras and an 8800 gts 640 (power hungry monster) with my corsair, and I'm not afraid of going sli in the near future with a cheap 640.

A PSU problem is not one that you will ever want to have. Sometimes very hard to detect, sometimes it takes other components with it, sometimes it takes you home with it.
