Would I need more power?

Specs: Microsoft¢ç Windows Vista¢â Home Premium, 2.8 GHz / 6135 MB
I just bought a computer. Here's the spec.

AMD Phenom(TM) II X4 920 quad-core processor [2.8GHz, 2MB L2 + 6MB L3 shared, up to 3600MT/s]
• 6GB DDR2-800MHz dual channel SDRAM
• 320GB 7200 rpm SATA 3Gb/s hard drive
• 256MB NVIDIA GeForce 9300
• Blu-ray player & Lightscribe SuperMulti DVD burner
• Integrated 10/100/1000 (Gigabit) Ethernet

The graphic wasn't really good enough so I bought a Sapphire HD 4850 512mb and Antec earthwatts 500 watts.

Would I have enough power? or do you guys think I need a bigger PSU.

wait a minute....this calculator isn't accurate.
When I bought the computer from HP it came with geforece 9300 & 350 watts power supply.
I put those in the calculator and it says I need 480 watts.
This doesn't seem right...

You should be fine with a 17a 12v rail; I think a HD4850 only needs 11-12a max.

Wattage calculators are unreliable. Amperage is what's important. Your power supply *may* not have needed replacing.

Newegg just had a Sapphire HD 4850 512MB on sale for $75. Did you cash in on the deal?
