PSU choice clarification

[boss_b_mcboss]

SO...

I've determined that I need roughly a 430-500 watt PSU for the rig I have...

ZOTAC! AMP GTX 550Ti
Phenom ii 6x @ 2.8ghz 1055T
8Gb PNY optima DDR3 1333
500GB 7200 RPM HDD
LITE-ON DVD-CD drive
ASrock AMD AM3 770 ATX mobo

My current psu:

Thermaltake TR2 W0070RUC 430W

My questions:

A. Will it work my current PSU
B. If not what PSU do you recommend within the same price
C. I heard something about my current PSU not having enough "continous amperage". How do I determine how much it does?


Thanks!

I'd personally replace that unit,it's an old outdated design and probably supplies 350W max.
I'd say it won't provide the required power for your specs.

What's your psu budget?
What country do you shop in?
