So I think i'm gonna upgrade my PSU cuz the one I currently have is a 350w ( AcBel HBA008 ZA1GT 350 ) and I'm going to be running a gt545 gpu. What should I be looking for? I think mine is a 24 pin. So should I be looking for maybe a 500w 24pin?

Take a look here at the psu tier list. It gives a general idea of what psu's are better based on efficiency/quality ranked from best (tier1) to lowest (tier4/5). It's best to try and pick one from either tier 1 or tier 2a - 2b would be the lowest I'd consider and would probably avoid tier 3 and lower.

Most psu's anymore are standardized and should come with all the appropriate connectors (like atx12v2/3) etc. They come with the 24 pin motherboard connector and usually an 8 pin cpu connector or sometimes split it to a 4+4 cpu power connector to fit different motherboard configurations.

350w is the minimum recommended. 500w may be a bit overkill for that gpu, but it will allow you to get a better gpu in the future and not run out of...

For that reason you may want to look into a 550-620w unit. Usually a good middle of the road wattage with capabilities for a lot of different video cards.

Yes, a 500w 24pin will be fine.

However, you must buy quality, not the best deal! A cheap PSU can lead to the destruction of your entire system, or, simply give out too soon, requiring replacement. A cheap PSU might be listed to have the wattage required for a GPU, but actually not have the proper Amps to do so.

So, go for a trusted brand, like Seasonic, Corsair, XFX. Steer clear of Thermaltake, Antec, Raidmax, and the like.
