Which PSU? VX550W, HX520W, or the one I have?

I got the Ultra X-Connect 2 for x-mas. Even though he's my older brother, I don't really know about the model of psu. If I did need to buy one asap for some reason though, which Corsair would you guys buy? I don't really care about having a clean looking inside. I mean, I won't be overclocking. I won't have a sli/crossfire setup. If I did buy a 9xxx card or a x2 card from ATI, or more power hungry card, I'd obviously buy a more powerful psu. But I mainly bought the stuff for Starcraft 2. And I remember the first one. They (Blizzard) know how to scale their game for a wide variety of computers. If you think the one I got for FREE is suitable, say so please. It will be on 24/7 unless I'm afraid of a surge or something. But I won't be on it 24/7, obviously.

This is what the psu will be handling.

ASUS P5K-E (non wifi edition)
E8400
Evga 8800GT (G92) 512MB (stock speeds)
1, CD/DVD Samsung burner
Arctic Cooling Freezer 7 Pro
2, 250GB WD: Caviar HDD's (Mirroring each other)
Corsair 4GB kit (2 X 2), the purple and black one's

Thanks again in advance.

P.S. - If I did upgrade the video card eventualy. It would be a nvidia card.

I would go HX620 for modular, should give enough headroom for any single card and single socket CPU for years to come.
Non-modular then Corsair TX650 or TX750.
And yes the HX620/TX750 are quite similar in price (in UK at least) you're just paying the extra for modular, which I find very handy.

I'll be buying that 620HX, if the Ultra can't power everything. Which I hope it can't, so I can buy a dependable psu.

I'd get the HX-520, there is seriously no reason for 620W with a single card setup, your system will draw less than half that.
