There is no cap on wattage. You may not have connected everything correctly.

Post the brand and model of your computer?

In the past some computer brands used propitiatory power supplies which had the power connector wired differently. Installing a standard power supply in that case will fry the motherboard. Hopefully that is not the case.

To know if the old power supply is propitiatory post the information off the label.

I see where you may have a small form factor or slimline case. Is that correct?

Did the new power supply fit without any mods?

Well, I ran into the same thing once. Never did figure out why the board wouldn't POST with a more powerful PSU.

What is the model of the 500W replacement?

That doesn't look like a quality unit. Also, it has 2 12V rails, which is not ideal. I suggest you get a unit with a single 12V rail.

The 250W Bestec PSU is junk, so you should replace it. My question is this. What are you running or intend to run that requires twice the Wattage?

Did you add a graphics card or what?

Well, first you need to determine how many amps you will be drawing on the 12V rail. Corsair is an excellent brand. If you don't intend to upgrade your graphics then you are barely managing with 14A @12V so a PSU with 20A@12V should work for you. Look at the link below. Newegg.com is an excellent online vendor if you live in the USA or Canada.
