Hello I just bought a 8800GTS 512, and I am now looking for a PSU to go along with it.
 
The 450 and 550 corsair looks appealing.
 
However i have a Hiper 580w at a very appealing price.
 
 Here is more about it,

Please i need urgent reply because I am bidding on it, on ebay.
 
many thanks

a very good brand 550W is enough.but its better to have a 700W PSU if you intended to keep it for a while and do overclocking at the same time.

I have an E6570
2 gb of memory
320 GB HD
DVD RW
8800GTS 512MB
 
I don't overclock, and I intent to keep this system for some time.
 
So Is the above PSU considered a good brand?
 
Cheers

yeah the corsair 550w will do very well.anything else need help?

those are excessive!in fact extremely excessive!forget about them!

I think you misread it. A 400W PSU for the entire system is NOT excessive.

oh yeah i did!lol i thought it said 400W just for the graphics card!lol

Hiper is not known as a quality PSU manufacturer.  I would use one if I had to, but I wouldn't purposefully buy one.  How much is your PSU budget?
