I have a lot of question about Aerocool Zerodba 620 Watt.
I wanna buy mainstream PSU for: ASUS Striker Extreme Intel E6700 1 or 2 Radeon 2900xt CORSAIR XM2x2048-6400C4d Western Digital Caviar RE2 WD5000YS And 2 Optical Drive
I read article from "http://www.performance-pcs.com/catalog/index.php?main_page=product_info&cPath=22_267&products_id=4187" and I found that this power supply don't have PFC? As much as I know that hi-grade power supply always have "Active PFC" Can this PSU supply my stuff? Do you have any suggestion for great PSU below $150?

You will want a more powerful psu than that. PFC is more marketing hype than anything useful, it will not make your psu any worse without it. However, a psu such as the silverstone olympia 650w is a good choice, as it has the new 8-pin connector for your 2900xt. If you want 2 2900xt's, you will need to spend more than $150 for a psu with 2x8-pins connectors, but it is possible to use 6-pins and therefore pay a bit less.
Could you help me to list your reference PSU that have 8pin connector or PSU that can support 2900XT? I'm confused because so many PSU on your list.
