So, I'm planning on buying a HD 4650 but I'm afraid my PSU won't handle it. You can see my rig and my PSU specs below:
CPU: AMD Athlon 64 X2 7750 Kuma 2.7GHz @ 3.0GHz 95W
Motherboard: Asus M2N68-AM SE2
Memory: APACER 2GB RAM PC-6400
HDD: WD CaviarBlue 320 GB, SATA 3 Gb/s, 7200 rpm
ODD: DVD+/-RW

ATX 300W PSU
14A +3.3V
14A +5V
14A +12V
0.5A -12V
12V RAIL=>164W
+3.3V, +5V, +12V 280W MAX LOAD
TOTAL OUTPUT IS 300W

That PSU calculator recommends 215W so it will be cutting it really close on overall power, and likely trying to over draw the 12V rail as 80% of the power comes from the 12V rail. Is it a normal sized case? If so you should be able to fit a normal PSU as a replacement, something like the Corsair 400CX is inexpensive and good with plenty of power.

At first I thought about buying a HD 4670 but I realized that it would kill my PSU, so i switched to 4650. I have a normal case but I live in Albania, so I can't purchase online :( , and I'm kinda low on budget right now as a 4670 costs $100 here, and 4650 $80-$90

Your cpu is a little on the hot side (95w version) which uses a lot of power that psu is rated for. So I would look for a better psu at some point to be safe as for the gpu prices suck in general now even in the US (rising prices even on vintage hardware) so all I can say is either look for a used card that you know that works locally or save up. Saving up isn't a bad idea while shopping around in the mean time will help you find better deals or at least more options. If you are lucky while visiting any local pc shop if you find a used antec neo power 550w that is in good shape it is a really good psu and have used my 8800gtx with it with out going below 12v on the 12v rails.

the 4650 barely draws any watts, plenty of people use 250w PSU to run it

I'm running a low profile 4650 in my Dell XPS 210 with it's meager 275W PSU. As long as your PSU is of decent enough quality you should be o.k. Just don't expect any miracles from the card. That dell has an E6700 and it struggles a little with newer games. Still, it's good enough to play Ghost Busters and SF 4 at a little above medium quality ^_^. It's hooked up to a 720p TV though so not too demanding on the ol resolution.

Honestly never buy pre-built systems. The powersupply is almost always sh** and you are left with a mess when you want to upgrade.
