Can my pc handle this graphics card? (300 watt psu)

Under system requirements from AMD, they have listed a 400w PSU, so I would buy a new PSU on the safe side...a good 430w PSU is like $30, so totally worth it in that asspect.

thank you very much

can u link me where the 430watt psu is preferrably on newegg or amazon

The 6450 requires a minimum of a 400w power supply to be in your system , you can always try to run the card with that power supply and see if it works. If it doesn't then it will shut down or give bad pisture quality but it shouldn't ruin your system. However you could upgrade the psu to 400w and not have to worry.

CORSAIR Builder Series CX430 V2 (CMPSU-430CXV2) 430W ATX12V v2.3 80 PLUS Certified Active PFC Power Supply
$44.99 and a $20 rebate makes it $24.99

ENERMAX NAXN ENP450AST 450W ATX12V Power Supply
$39.99

There are a few to choose from and the choice naturally is yours to make but you do want to stay away from the noname brand and try to go with the proven quality brands. Antec , Silverstone , Corsair , Enermax , Cougar and Seasonic.

i just bought the 430 watt corsair off amazon thank you very much for all of your help!!!
