No,
I don't think your PSU can handle a 5770
However,
5750 will do fine with that

My suggestion
Upgrade your PSU

To atleast 450W

Corsair makes very good PSUs, and either 5750 or 5770 do not use that much power, and I am almost sure that your PSU will handle the 5770, especially that your computer does not contain power hungry parts.
But you may have a cpu bottleneck from your e4500.

Should be enough. PS has 30amps and your hardware isn't over powering.

Here are the ATI recommended power supply requirements for the ATI Radeon HD 5770 and 5750 video cards:

450 watt or greater power supply with one 75 watt, 6-pin PCI Express® power connector recommended

600 watt or greater power supply and two 75 watt, 6-pin PCI Express® power connectors for ATI CrossFireX™ technology in dual mode

Corsair 400CX will easily take the load of 5770/5750.

5770 takes lesser power than a 9800GT and 9800GT takes much less power than a 4870.
I'm running a 9800GT and my friend is running a 4870 on a 400CX for quite a while.It doesn't even gets hot(Not even mildly).

Corsair 400CX is a very good PSU.

Moreover your Processor is a dual core.
Do you already have the PSU?

It will easily run the card.
But do you want future upgrade option open? Are you a hardcore gamer?
I mean will you ever need a card that will have high power consumption?

The general rule of thumb is a high quality 500 to 550 watt power supply with sufficient current (amps) on the +12 volt rail(s) can easily power a system with any single video card made. A high quality 700 to 750 watt power supply with sufficient current (amps) on the +12 volt rail(s) can power a system with two video cards operating in dual mode. There are a few exceptions like the new ATI Radeon HD 5XXX series cards which use less power due to their energy efficiency.

A high quality 500 to 550 watt psu will have a +12 volt rail rated at 40 amps. A high quality 700 to 750 watt psu will have a +12 volt rail rated at 60 amps.

In addition the power supply should be at least 80+ Bronze certified for energy efficiency. There are some models available which have achieved 80+ Silver and 80+ Gold Certifications.

Before purchasing a new psu you will need to decide whether you will eventually have a pc with one or two video cards.

Corsair and Seasonic are two of the brands that have a reputation for high quality power supplies that consistently earn high marks in technical reviews. They are reliable, stable, and come with a 5 year warranty. Some of the newer models come with a 7 year warranty. Lately we've been seeing a few other brands offering some high quality units. One example would be the Antec Earthwatts series which is a major improvement over Antec’s older psu’s like the Basiq models.

@johnny
i dnt plan on gettin two cards....not in da near future probably

Corsair gives 30A on 12v rail...is it good fr da cards mentioned and gigabyte 460 superb gives 14A on 12v rail1 and 15A on 12v rail2...does it mean dat it gives 29A for one card

The answer to your question is this time yes. It does not always work that way because it depends on the maximum wattage of the +12 volt rail(s).

The maximum wattage on the +12 volt rails for this psu is 348 watts. The information is right on the data label of the power supply.

348 watts divided by 12 volts equals a total of 29 amps.

It will easily take the load of HD5750.

Well...they may recommend more wattage, but I'd actually say that it would have no problem with it. ATi might give that suggestion because lower quality OEM PSUs found in your ordinary Dells, HPs, don't necessarily live up to their proclaimed wattages. Basically it might take a 600W PSU to put out 500W..A good Seasonic, Corsair, or Antec supply have much better capacitors and thus deliver more power and better more consistent power.

I don't want to completely put you in the clear, but you are pretty darn close and I would do it if I were you.

Well, you're almost right, it really has nothing to do with the oem's found in Dells or HP's.
