Hello,

I'm planning to upgrade my GPU to the HIS iCooler HD 7770 1GHz Edition. I wanted to know that my current power supply is good enough for this card or not. My complete system specs are as follows,

PROCESSOR: Core i3 3220 3.3 GHz Ivy Bridge
RAM: Kingston 4GB DDR3 1333MHz
GPU: MSI HD 5450 1GB DDR3 650MHz
HDD: Seagate 500GB SATA II
PSU: ThermalMaster 420W ATX without 6 pin connector - 12V1 = 10A and 12V2 = 13A, Total 12V = 23A

I'm an everyday gamer and I plan on using a MOLEX (4 pin to 6pin converter). Will my power supply be able to handle the GPU along with my system ?

No it will not be enough. Don't upgrade to HD 7770 without getting another power supply unit.

Thanks to all -- Will the COOLER MASTER GX Series 450W be suitable replacement to my current one ?

The gx series is garbage
Only the silent pro from cooler master is good
The 430 I listed is a solid psu and will serve you well

Well, honestly, now I am currently running with a HD 7770 with a CM 460W PSU, and I must say the performance is quite well, without OC. The rest of the PC Specs are the same. :p  - Battlefield 3 at AVG 46-47 FPS @1280x1024 :p  :p 

Anyway thank you everyone for their sincerest response. Cheers :)
