Are you saying that you have a power supply that is 450w. The graphics card is recomending that you have a 600w power supply in your computer so it will power the card and the rest of the computer with that 600w power supply.

The 5770 requires a 500w power supply to be in your system and a 600w power supply for crossfire , so if your power supply is 500w or more then you can run the 5770 card in your computer.

If you have plans for crossfire then I would get the 600w or higher , but it you are just doing a single card then the 500w would be sufficient.

It will depend alot on the brand card that you buy , I just looked up a Saphire 5770 and the recomended psu on thier site was 500w and I think it was due to the dual fan design.

I think it matters more on the PSU. A good 380/430W PSU should be fine with a 5570.

I'd go with 500 W QUALITY psu. Don't buy psu just from any company, it might ruin your system and your hard earned money. Go ONLY with known companies such as Antec, Seasonic, Corsair, XFX.

Again, it's going to depend on WHICH 450W PSU.

It never does hurt to have a bigger power supply then what you actually need , but if you get to the store and look on the video card box you can see what the recomended power supply is and then you can either go with that or a slightly bigger one.

There are more and a good way to see how a psu is would be to read the feeedback on the one you are looking at and do that on a few sites that sell it so you can get a snse of whether or not it is a good psu to go with.

I would take the areocool, but only because I can't find anything on that iSONIC. The areocool has a lot of issues as well.

Quote:
Voltage regulation failed on the -12 V during our light load (20% load, meaning 120 W) test, but all other voltages were inside specs during all tests.

Although inside specs, noise and ripple were very high when the unit was delivering 600 W.


On the bright side it can do 600W.

Corsair 600W Gaming 80+ is probably the best price/performance ratio PSU you can get for your cash. It's efficient, delivers it's rated wattage and has long warranty in case it fails. It's a very good investment!

With your setup you don't need the 600W Corsair. Even the Corsair 430W would work with a 5770. Get the 600W only if you are going CF or a larger GPU.
