[k_daredevil]

hi guys
i decided to get a new vga but the problem is that my power supply is a green450watt with one 12v *16amps rail,so here is the question:
can i get a 8800gt or 9600gt or i have to change the psu first??
thx

Change the psu.
Here's a 450w unit with 33 amps on the +12v

From what I understand a single 9600gt requires 26A on the 12V line and the 8800gt burns more energy as well. You need to upgrade your psu first. get a good psu with ~30A on the 12V line it will be more than enough for your needs.

I don't want to star a new topic for the same question so I'll ask the same thing in here if that's ok.

This is my PC right now only I'll be adding a 8800gt or 9600gt

AMD 3800+ (single core)

2gb Mushkin DDR2 800 (PC2 6400) ram

Enermax Liberty 500w PSU

Asus M2N-E AM2 Motherboard

Here is a link to my PSU...please let me know if it's enough.

grackus, your enermax has plenty of juice for the 8800gt. i have the 400watt liberty and an 8800gt and works flawlessly. the combined 12v rails give you 32a (see picture on side of psu) while i have 30a with my 400watt. you only need 26a. enermax makes real nice psu's.

Thanks for the reply!

For the 8800GT you need 23 amps on the 12v rails.

For the 9600GT, you need 20 amps on the 12v rails.

New PSU. If you even have to question your current PSU I wouldn't risk it. Just get a solid 550W or around there. Corsair PSU's are pretty cheap on Boy.com from what I hear.

The 550W Corsair is a decent performer, I've got one myself and I've never had any problems with it.
