About the PSU

[Issue Games]

I am thinking of upgrading my GPU
My current specs are:
i3 3220
4GB Kingston DDR3 RAM 1600MHz
Nvidia GT 630 4GB;
I'm upgrading to GTX 660 3GB, I've searched the internet and I found that a GTX 660 would need a high power PSU(550-580W), I tried checking my PSU power rate but I found it doesn't have it written on its label not even total wattage etc.
Here's a Shot:

I need you guy to find out the Power rate, total wattage etc of my PSU and that can it handle a GTX 660?.
P.S: I'm low on budget and couldn't afford a new PSU with a GPU. If you have troubles reading the image please let me know I'll try clearing it out for you, the room was dark so the quality isn;t too good.

i cant realy see anything, the pic is upside down for me and its in bad quality.. try searching for a model number on the label

Looks like a stock unit. Is this a pre-built PC? (Dell, HP, etc.)?

Either way it doesn't LOOK like it could handle the 660, even if it had the necessary 6-pin PCI-e connector.

I did and I couldn't find.
I know its in bad quality but it's readable.

The sticker says 12A output on the 12V rail. That is barely enough for the GTX 660 alone, leaving none to spare for the CPU and the rest of the system.

If you want to upgrade the GPU without upgrading the PSU, the best modern GPU that might work is the GTX750.

So the total wattage of the PSU is greater than 550W(which is enough to handle GTX 660 along with other Hardware) then?

Nope it's a custom build

No.

CPUs and GPUs draw nearly all of their power from the power supply's 12V output.

The i3 and its support circuitry need about 70W from the 12V rail.
The GTX660 needs 120-150W from the 12V rail.
Your PSU's 12V rail is rated for 12A, which is 144W.

Your PSU is at least 50W or 4A short on the 12V rail from being capable of powering that hardware and that is before counting HDDs, CD/DVD drive, fans and possibly other things also powered from the 12V rail, so add another 4A or so for that.

Then there is also the power supply quality issue. Since I have no idea what that brand is, I am going to presume it is worthy of tier-five (junk) status on the PSU list.

If you want to know what your PSU's total (alleged) output wattage is, simply sum up the voltage*current of all output rails. At a glance, you get about 260W but that does not mean anything useful when that power is not on the outputs you actually need.

Long story short: you should consider getting a new PSU before upgrading anything else.

ok so your psu is 200w.. you need minimum 450w, i whould suggest looking for 500-550w psu

Can you guys suggest a good PSU under 4K(PKR)?
