Leishi; NEITHER would be the best choice. U want a cheap, decent powersupply? Look @ Allied/Deer, Raidmax, Powmax, InWin/PowerMan (if you can find one bigger than 400w- I've only ever seen 235 and 300w ones, but they're decent for their size and price) and Enlight... However, I'd really recommend an Antec over anything else. I mean my 400w Pre-Smartpower/TruPower Antec is still chugging away, and is currently powering the K7D-L system with a single 2200+ (I'm not hard coding multis on those bartons until I test them @ the speed I want and my A7N8X is dead, and I doubt my KX7 can do 200MHz+ FSB speeds), and it's soon to be powering the dual 2500s @ (hopefully) 2.125GHz, 4 160gb Maxtor HDDs (Gotta love competition- Staples was out, so I got 'em from fry's for $90 each after rebates, and 3 of 'em have ATA-133 cards with them that I should be able to get $20 each for...) and possibly 2GB of DDR and a GFFX5900 or R9800 256 (not sure yet) and I've never had problems with it. It's powered every system I've had since I bought it at some point, and it's never caused a problem... if you aren't having problems with yours, I'd leave it.
