I just bought a second HD4830 and found out that my PSU wasnt strong enough to power both cards up. My PSU is "Jersey ATX-BE-600WS" and got pretty low Ampere numbers. Do you think this PSU will be abel to power 2 HD4830's?

Yeah, Your PSU is a piece of junk :/ 
It may be (just) able to run both GPU's but I would not recommend it.
Look into a new Corsair, PCP&C, Seasonic, OCZ or Antec Earthwatts 550w+ PSU when you can afford one.

"outlw6669" is right....
PSU is not something you want to save your cash on.
It can do some dmg to all your parts if it fails.
Can you tell us your full configuration?

Like a 5750 or 5770.

But, I live in Sweden, and that PSU I just linked is at the same price that a Corsair TX 650W, so, I should go for that one ? :)  Peoples who bought it says its really quite and got amazing power! sounds good to me :)

and btw, I got a AMD Phenom x4 9850 BE, two HD4830's, mobo = ASRock A770. Nothing is OC yet.

Yes, the Corsair TX650w is an excellent PSU and is highly recommended.
It is much better than your current one.

While a single faster GPU probably would have been a better option, the two 4830's you already have will still perform quite nice.
I would expect it to perform somewhere between a 4890 and 5850 at stock speeds.

Yeah I know that HD4830 works good good in CF :)  And Corsair TX650W should handle both my GPU and CPU OCed right? :)  Got pretty good cooling so :)

Yes, there will be no issues with CF 4830's on a Corsair 650.

Most Cooler Master PSU's are pure junk.
A few of their newer ones are actually somewhat respectable though.
Based on a Review of the Real Power 850w, I would say this particular PSU is in the latter category.

If it is significantly cheaper than the Corsair, go for it!

Corsair TX650 watts will be perfect for CF 4830 to the effect that one HD 5970 consumes 620 watts

First, let's take a look at the official ATI recommended power requirementsfor the HD 4830 video card:

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

550 Watt or greater power supply with two 75 watt, 6 pin PCI Express® power connectors for ATI CrossFireX™ technology in dual mode

The recommendation is for an entire pc system.

Next let's take a look at actual power consumption of the video card:

A system with two HD 4830 video cards does not require very much power.

An appropriate choice would be the Corsair VX 550 power supply. Corsair has a reputation for high quality power supplies. They consistently earn high marks in technical reviews. They are very stable, reliable, and come with a generous warranty.

You mentioned the Corsair TX650 power supply. It is another high quality power supply that would provide you with a future upgrade path. You would be able to upgrade to the HD Radeon 5000 series video cards. If it is available for a good price, then go ahead and buy it.
