Could I run an ATI 5770 with my 450w Gigabyte PSU?

[Guest]

Hello,

My PSU is a Gigabyte 450W and currently runs my ATI HD 4870 fine.

I'm also running a non-overclocked Intel Q6600 on an Asus P5Q mobo.

I need to upgrade my GPU as the fan on my 4870 has conked out.

I was wondering if my Gigabyte PSU could run the ATI 5770 alright and also what size the card is compared to my current one.

Any help would be appreciated.

Cheers,
Luke

Cheers for that mate. So it would be safe to purchase the card with that 450w PSU and the Intel Q6600?

Totally agree with ct1615.
But you might want to consider an aftermarket cooler for the existing HD4870, or possibly using the old fan and cable ties trick if you have a non reference cooler.
Even if you go for the HD5770, it may still be worthwhile putting another cooler on the existing card: That way you can at least E-bay it or flog it through the Classifieds.

and performance wise the 5770 is pretty much the same as 4870.....
