will this be enough for now

I would be very wary of FSP Fortron PSU's myself, check out 4Ryan6's thread http://www.tomshardware.com/forum/244206-28-trouble-ville and then please get something else. I have been using Corsair's HX620's in my gaming rig since Easter and have had no prob's at all my gaming rig is a 939 3800x2 with Sli'd 7900GT's & 5 HDD's + DVD/RW and my workhorse rig is currently running an E6850, 7900GTO and 8 HDD's + DVD/RW and is also powered by a Corsair HX620.

i already had the fps forton ax450-pn for over 3 moths i just wanted to know if i can handel it for the next 3 to 4 days


also what if i take my 8800 out and put my 7600 until i get the psu will i be in a safe zone until i can get a new psu?

I would say no. When the 8800GTS was first released, nVidia advised PSUs in the range of 450W with 27A on the 12V rails. At that time, this one barely met that limit (it's 450W with 29A on the 12V rails). However, since you have a Quad, which is more power hungry (105W or 95W TDP v. 65W for most Core 2 Duos), I would not recommend this PSU for you.

Moreover, the PSU isn't the item you want to cut corners on. It's the backbone of a good rig. Get a good quality PSU, and the Corsairs mentioned by mousemonkey are very good. In your case, the smaller sibling (Corsair HX520) will work just fine for you:

And cheaper here:

To answer your last question: If you don't play games during the wait to replace the PSU, you'll be fine with the 8800.... it's only when you fire up games that the video card will draw power. If you want to game a bit, and be safe, it's a good idea to put the 7600 back in. The FSP will be enough for the Quad with the 7600.
