GTX650 Ti and this PSU: Is it good?

No, as the 650ti requires at least 20amps on the 12v rail, and that only has 17a on a rail. Look into single rail power supplies or go up towards 500w.

How about my current PSU?

It appears like it, but the picture is difficult to read. I am here in the States, so I don't know if that is a name brand there, but I do not recognize it. I would go for a higher quality unit, such as those made by Corsair, Seasonic, or Silverstone.

Oh, ok thanks. but just to be sure I have a backup PSU, will this one be any better? It's relatively cheap but appears it will do the job.

For a system using a single GeForce GTX 650 Ti graphics card NVIDIA specifies a minimum of a 400 Watt or greater system power supply that has a maximum combined +12 Volt continuous current rating of 20 Amps or greater and that has at least one 6-pin PCI Express supplementary power connector.

Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Sufficient Total Combined Continuous Power/Current Available on the +12V Rail(s) rated at 45°C - 50°C ambient temperature, is the most critical factor.

Overclocking of the CPU and/or GPU(s) may require an additional increase to the maximum combined +12 Volt continuous current ratings, recommended above, to meet the increase in power required for the overclock. The additional amount required will depend on the magnitude of the overclock being attempted.

The Zalman LE Series 400W (ZM400-LE) power supply unit, with its maximum combined +12 Volt continuous current rating of 25 Amps and with two 6-pin PCI Express supplementary power connectors, is sufficient to power your system configuration with a single GeForce GTX 650 Ti graphics card.

Thank you very much for your helpful answer. before I end this thread, I just want to verify if my current PSU can handle it.

Basically it's a Powerlogic 600W. Can't find any pics so here are some blurry images fom google.

Does that Powerlogic ATX-600-W have at least one 6-pin PCI Express supplementary power connector? If the answer is yes then it may work.

No But I'm planning on buying one of those Two 4-pins to 6-Pin Adapter Cables. if I use that, will everything be fine?

Not necessarily. It depends on how old that Powerlogic ATX-600-W PSU is. As the electrolytic capacitors age in the PSU it causes the PSU to lose its ability to deliver its full rated power capacity specified on its label. If it's more than three years old then don't trust it.

If you really want to buy a PSU, don't get the Zalman, get this one since it is of much higher quality for your budget:

Don't buy the Huntkey, it's a piece of trash.

I don't think that the Enermax hass 6-Pins. Or does it?

Yes it does.

PC Express specifies 1 x PCI-E on their web page. It is most likely a 75W 6-pin PCI-E power connector, not the newer 150W (6+2)-pin connector.

The Philippines seem to sell a lot of obsolete/discontinued PSU models.

Last thing, since this is myu first time replacing my PSU. Do you just remove the old one and screw thw new PSu in? Is it kinda like changing video cards? Or is there more to it?

oh and yeah Philippines sells a lot of old hardware here. Most PC's here even run on Windows XP and Pentium CPU's.

BTW by obsolete stuff do you mean the Enermax? Or the other PSU's on the list?

The PSU is held in by four screws on the back of the computer case. Removing those four screws should allow you to slide the old PSU out.

Remember where each output power cable is connected with the old PSU because you will have to connect the new PSU up the same way along with plugging in the 6-pin PCI-E cable from the PSU to the GeForce GTX 650 Ti card.

So this means that all PSU's are the same size? I shoudn't have any problems if it will fit in my case? Just swap out the old with the new PSU?

The picture of your current Powerlogic ATX-600-W PSU shows that it is a standard PS/2 form factor PSU. It should just be a straight swap.

Thanks a lot for your answers to my MANY questions ko888. These answers will surely help me out when I go buy my new Video Card and PSU.
