ok, i know that's ridiculous, i just want to make sure, how much risk?

i just bought thermal take power express 250w which is a dedicated psu for my 8800gt, will my pc runs fine?
rig in sig.
 
Yes, of course.

Why wouldn't it?

Of course, it probably would've been more prudent to have just replaced the old Butterfly with a better, beefier PSU.

For just a little more money, you could buy just one unit and that would mean better efficiency, less cable clutter and better reliability.
 
thanks mr JonGerow,
i've just installed that psu and you're right about the cable, now i have a huge pile of cable inside my case, ouch.

there was a 460W psu, i think it was gigabyte superb series. it comes with dual 18A or whatever at least dual 12v rail, but i thought it was silly that i'd downgraded my 480W to 460W, besides, i don't really into that brand, you know, it could be poor quality, i can't find any review on that. because my Budget only allow me to chose between that gigabyte psu and this power express, so i went with power express one.

would it be better if i just bought that gigabyte instead?
 
You can't go on wattage alone, my 380w Antec Earthwatts has 2 x 12v rails @ 17a
 
As a dedicated PSU for the videocard, it should be OK. Powering an entire system with less than 20A on the 12V is probably not a good idea.

Until recently, I was running my entire system with an old (2001?) 430W Enermax. It had more than enough juice on the 3.3V and 5V rails, but its 12V rail was only 20A. With AtiTool stressing the videocard and Orthos stressing both cores on my X2, it was really struggling to keep the 12V within 5%. I was seeing 11.4V, 11.3V.. Which is why I upgraded to a 450VX, which actually has lower amperage on the 3.3 and 5V rails, but much higher on the 12V.

That's with a Brisbane 4800+, an 8800GT videocard and a single 7200RPM harddrive.
