Hello, I have an old pc with PSU called Golden Power 550W, Never heard about it, I used my pc for 1-2 years, And i'm upgrading, And since i'm on a tight budget I don't want to waste my money on things I already have, Here is a picture, http://imgur.com/ih16v4J , I captured it in a wrong angle, Hope any one can help, Thanks for your time.

Hi - It's a smal Hong Kong based company. PSU's with more than one +12v rail output less than the
combined +12v amps listed. So, this unit will have less than 30 +12v amps. Would be helpful to know
the exact amount, but I couldn't find the specs.

It also appears they no longer supply PSU's and only supply batteries. They also look to be a
trading company and don't sell items directly to...

Not sure about the quality, I suspect fairly low.
The combined rating on the +12V rails is 30A.
If it can actually put this out, you might be OK with a graphics card up to 160W with an intel CPU (assuming 84W CPU) or up to 120W with an AMD CPU (assuming 125W CPU).
This limits you to a GTX 750 Ti or R7 260X. Performance is similar but the GTX 750 Ti uses 40W less power and would be the safer option.

Assume that it will output 25 +12v amps, which might be generous given the nature of this item.
25 +12v amps on a 550w unit equates to an old platform/inferior quality.
A good quality modern 550w unit typically has ~40-44 +12v amps.

That does leave you with the 750ti mentioned above or an R9 270x.

If you can afford to do so, you should upgrade the PSU. There is no assurance this unit has the protection
features to shut itself down if it get's pushed too hard, and could take other components with it when/if
it burns.

Personally, I wouldn't gamble any PC upgrades with this PSU.

The R9 270X is a 180W graphics cards.
If it were suitable, a GTX 760 would be as well.
With these cards though the system would draw about 25W on the +12V rails even with an 84W CPU.
These cards require two PCI-E power connectors.
There is no way they are suitable.

AMDs offering with the same 60W TDP as the GTX 750 Ti is the R7 250, but this is a much slower card. These do not require a PCI-E power connector and would be the safe option with a questionable power supply. The GTX 750 Ti would be the better choice for performance.

AMD also offer the R7 250X, 260 and 260X at 80W, 95W and 115W respectively. These require one PCI-E power connector. The R7 260X has equivalent performance to the GTX 750 Ti but with a TDP 45W higher.
These cards are probably suitable.
The R7 265 and R7 270 both have a TDP of 150W. I think these would be pushing your luck with this power supply.

You are probably right that the +12V rails cannot both output their rated limit at the same time. There should be a specified combined limit if this is the case, but it is not marked on the PSU.
