The HD5750 never realistically (Gaming) uses 60Watts, as Furmark is the ultimate GPU stresstest.
One thing I have to add....actually speaking I have a generic 300w psu here....My friend is selling his FSP 300W PSU for cheap cuz he is in need of money(only 20$)...The mercury one can be bought for around 15$ whats the best bet?
He is indian or atleast if not exactly a neighbour. Thats for sure,
Reasons: These PSU are used in India, Bangladesh and Pakistan.
The rest of the world has more options.....lol
Not that we don't have options here but going in for anything higher than the standard 450Watt PSU that is available here for 450Rs. (INR) which is 10$ (US) lol
If you plan to use anything other than what you have specified, I'd suggest you go for the PSU's ranging from 3000Rs. to 10000Rs (INR)
I know thats a bit steep for a PSU but , if you want to game...... it certainly is not that cheap here.
I have a HAF932, 900Watt PSU by Tagan, 3.5 TB HDD, Blu Ray Drive (ASUS) , MSi GD70 Mobo , Kingston HyperX 8GB DDR3, Corsair H5O on a PhenomII 965BE, with Two 5770 Cards....... Crossfired, with 2X 24 Inche HD Benq Displays.....
And the whole rig has cost me approximately 1,50,000RS. thats about 3333$.
So you see it's not that simple , and this whole thing was made by me, had I got it made outside from one of the grey market vendors or from the branded guys, it's have cost me twice as much.....
So I guess, you see the difference is awesome.
What's an FSP??????
Mercury will be better since it's a 450 Watt PSU, and it has a 1year Warranty I guess, so you shouldn't have a problem.
But all this is only if you're having problems with your present PSU.
If it's working fine, don't change it......
Like they say, "If it ain't broken, there no need to fix it"
then it looks like the FSP is the best bet....I think the wattage maybe even lower when gaming (as the first guys said).....Wont there be a prob with the FSP PSU since I will be using wattage that is pretty close to 300
