So I'm building a new PC, first I was going to buy HD 7770 whose power requirement according to its description was 450W. But then I collected some more cash and now I'm thinking of buying HD 7850 for I want to play games on high setting on 1080p resolution. In the initial build I opted for Corsair VS450 PSU as it is cheap and of good quality. Here are my full PC specs-
AMD 3.3 GHz FX6100 Processor
Gigabyte GA-78LMT-USB3 Motherboard
Kingston V100 64 GB SSD + Old 250GB HDD
DDR3-1600 8 GB RAM
Corsair VS450 450 Watt PSU
Sapphire AMD/ATI HD 7850 1GB Graphic Card
GPU's description says that minimum 500W is required, but according to other PSU calculators which just calculates the Watts I'll be fine with a 450W PSU. Here in some thread I read only Watts doesn't matter but also stuff like v2.31 12v rail etc. I'm new to all this stuff and building a PC for the first time. So now my question is will I'll be fine with this PSU or I need to get a better one?
