Hi,
I did some research and i can't decide which psu will suit me best.
Im buying this pc with this graphic card.

The pc only comes with 300 watt power supply and The card needs minimum 450 watts.
Which psu will be right for me?
I cant afford a really expensive one, Maybe around 50$

This might be a stupid question, but Are all the power supplies the same size?
That means, will they fit my box?

the ones linked are all basically the same size. the OCZ is a fraction of an inch longer.

if you have a mini-tower PC (most DELL, HP, Acer, etc.,) or larger case, they will fit.

no, I would not pay $10 for that unit and actually has less 12v power (your video card runs off) then any of the PSU I linked above.

+1 for the Antec NEO 400W. Great PSU with a 30A single 12V rail. Won't think twice about powering a 5770.

the Corsair vx450 is also a great PSU, but since you are only looking at a single 5770, you might as well get it and not have to do a rebate. They are always hit or miss.

I guess ill go with this one http://www.tigerdirect.ca/applications/SearchTools/item...

But it only has one 12v output, Would that be a problem?


just about every PSU under 1000w has one 12v rail, even the OCZ i linked above that states it has 4 rails (they just use one rail and split it 4x)

What do you mean by hit or miss?

make sure you dot all your "i" and cross all your "t" on the rebate form. they look everything over with a fine comb and like to deny them for silly stuff. Most of the time they go through just fine. Just keep track of your rebate on the online tracker, the rebate form should have a link for you.
