how difficult is it to replace your wattage with a bigger one and are there any effects of installing a more powerful wattage?

Didn't get your query. Could you kindly elaborate with more words please.

If you mean changing the PSU to a higher rated one, there are no side-effects. If its of a good and reliable brand.... pure bliss! :ange:

No side effects, just buy a new one(make it a good brand like Antec, corsair, or seasonic, dont get a raidmax or anything silly) unplug everything inside the case, unscrew the old unit, pull it out, put the new one in, screw it in, and plug everything else back in.

Right now you can get the Seasonic S12II 620W unit for $70 from newegg, which is the same price as the 520W unit and less than the TP-550 or 550VX

250W is a major blow to your new GPU. Get a new one as mentioned by hunter315. That would do.

You mean you need a higher rated power supply unit,
You'll be fine installing a new one, the only side effects will be good ones :) 
As Hunter said, get a decent brand name, brand new

Yeah, get a brand name like Antec or Corsair. Those are the best ones.

The key is that, although the wattage output of the new PSU is much higher, the physical dimension will be the same as your old one. So it just fits into the same space. Your system will use as much power as it needs, as long as the PSU can supply it. The PSU cannot push too much power into your system.

One caveat is to make sure the form factors are the same. Is your 250W PSU an ATX PSU, or is it TFX or SFX? The last two are physically smaller. What case do you have, or if it is a pre-built (like a Dell), what model is it?
Otherwise, if it's ATX, the deal hunter315 found is good. I buy Antec or Seasonic PSUs myself, and would consider Corsair, Enermax, or possible XFX. If your PSU is SFX, there is a 300W model from FSP that has received good reviews.

Thermaltake has good PSU too.

I've seen Thermaltake's NEW PSUs reviewing well, but their old ones are overrated garbage. Avoid any PSU with a little voltage switch on it. At best it is an older, inefficient design. It is probably overrated. And it may be outright crappy, passing too much ripple and noise, or wandering out of spec when loaded.

you can read the PSU reviews from, they are very reliable source of PSU reviews. They test everything and even tell us what kind of Transistors or Integrated Circuit inside the PSU.
The only thing that needs to be consider when you change to a bigger wattage PSU is::: it is expensive especially the good ones :-)
