Watt is only used as a guideline when you purchase PSU, when calculated which required 220W, then , you need to find a 300 or 350W to cope with your current system.  However, modern system now consume 12V amp more than 5 years ago system which rely on 3.3V and 5V.  Therefore, those cheap PSU which shows 400+W have very high 3.3V and 5V but look at 12V rail, it is not even 20A
When you plug in a power required g/c, it drain power from PSU, but your other system also require 12V, HD,CPU,mobo all needs 12V, after 2-3 hours play, you suffer strange behaviour, you system can slowdown, you display seems flashing, your HD seems reading more and more slowly or even BSOD randomly.  Geez..I talk a lot

Acbel 350W has a detachable 24pin plug which means it is a 20+4 pin, I am using one if you read my sig and my mobo sure is many years older than yours.  Coolermaster don't have detachable 24pin plug, you need to buy a 24->20pin convertor.  The extra 4pin is for PCI-E board.  That's why some entry/mid level PCI-E don't need extra power because you already supply it with the 4pin on mobo.

8800 is a power hunger, a typical C2D equip with 8800GTX require 550W and if you use SLI, you certainly need 1000W PSU. Noted that 8800GTX(GTS only need one) need two 6pin molex and only 1000W supply supply 4 6pin molex. For your 700W PSU, think you can SLI GTS version.

Yours is a AGP/PCI-E board right? The board mainly is for AGP slot with PCI-E as extra for future use.  It is also great for people to switch to 775 socket to try out duo core while retain his AGP card, RAM and PSU.

Yours is a special case

Addition note : AGP is dead since 6 series card, but they keep it alive by adding a bridge chip to decode PCI-E signal to AGP. I didn't see the architech built out of your Asrock, I believe it is using the same technology. Correct me if I am wrong

Why not use your PCI-E slot?  You mean like a socket plug in AGP slot where you can plug in PCI-E card? There is, but don't seems to have it here, people rather change to PCI-E board than using back the old one.

A small PSU, perhaps for slim casing use. The 12V amp is very low and 200W! What pc you plan to use it on? A 486 or pentium 1?

Pentium 4 i think dunno, the pc ain't with me, its my friend's pc, he also dunno cause so long already the pc been turn off, that day when he want to turn on the pc, kaboom, the psu burn now wanna get a new one, but dunno bout it, isit available?? or obsolete already

E-J@1:
Perhaps take the pc together with casing to check what type of PSU it can fit in.  Cheap PSU is like that

I don't suggest using a cheap PSU to support high tech 8800, besides, cheap PSU don't have 6 pin molex.  There are people using such method to avoid buying expensive 1000W PSU by using a 450W for mobo and another 450W for g/c only.  You need to short circuit the PSU to think it is plug in mobo so that it can start (PSU won't start if it didn't plug in the 20/24pin slot).  I don't think people outside will do that for you and you void your warranty if something toast, not to mention get yourself/whole system electrocuted.
If you can buy 8800GTX SLI, it is nothing much for another 1000W, the PSU itself is cheaper than a single 8800GTX.

i wanna ask...wht is the diff between modular n non-modular psu?...
i wanna buy a psu for my rig...still figure between liberty 500w or silverstone st560f...
