So I plan to get a 7770, but because my PSU is too crappy I'll have to upgrade that too. Which of the following PSUs is guaranteed to give me least headaches?

1. chieftec 500w - 50 euro

2. chieftec 600w - 65 euro

3. fortron 500w - 55 euro

Also my motherboard is pretty old, but it could detect a 7750 without any issues, so 7770 should be the same just needs a bit more juice, correct?
*edit - linked the 500w chieftec in the 600w one as well

Dunno if its worth that much since I'll be running this low powered rig, and i do not intend to upgrade it at all - think ill just buy a new pc in 2-3 years since this one is pretty outdated with the 775 lga E5300. I just want something to be able to game a bit until i can afford a decent pc.
So one of these 3 PSUs should be able to do a e5300 + 7770 imo.

Well assuming these PSUs are kinda mid tier, and that i won't be using even 50% of their power I think I should be on the safe side. Heard that both Fortron and Chieftec are pretty solid, unlike my current CODEGEN which blows up all the time.
 
Well I have been running a FSP power supply for the nearly 3 years(24/7) without issues(300 watts i5 750 with a 5770 :) now it has a GTX 650 ti). I do not think they are THAT bad.

a 7770 is very power friendly to be honest.

I have no experience with chieftec or who they use for an OEM, but they seem to have lots of power.

The actual problem with CHEAP power supplies is most time they have all the power on the 3.3 and 5 volt lines. Then when you try to hit the 12 volt lines hard they fail.

I have seen one FSP power supply fail ever and it just shut off and never went on again. No hardware damage no fireworks, just off.
 
Check my online store list:

Here is one.... but they may not be secure. Careful about using them.

I see that this store in Bulgaria has Seasonic and Corsair

And in Serbia there are many stores.... this one carries Seasonic PSUs
