Hello,
I need to know what are the power requirements for EVGA GTX 550 Ti FPB 1GB VGA card. I've seen that I needs a power line of minimum 24amps on +12V rails. I have +12V rails but I don't know how much is the amp on them. Do you know how to find it?

Look at the sticker on the power supply.

EVGA GeForce GTX 550 Ti needs 24Amps on +12v Rails. If I had a lower Amps on +12V rails, Can I use The VGA?

EVGA recommends a 400w psu with 24 a on the +12v rails.

Every ul rated psu is required to have a data plate attached.

It should show the amps available on individual and combined 12v rails.

Older units may not show it this way. If you see the maximum watts on the 12v rails, divide by 12(volts) to get the amps.

Of your psu is a good quality unit, you may be ok with even less. If your psu is a cheap unit, it may not even deliver the advertised wattage.

If you have any doubts, you can replace it with a Corsair VX430 for $35 after rebate:

It depends. I'd say you could use it if your power supply has a 6-pin PCIe power connector:

I think I have 19A on +12V rails. Is it ok for EVGA GF GTX 550 Ti?

Do you have a 6-pin connector?

If your psu is a cheap brand, then no.
If your psu has the 6 pin pci-e connector like Sunius showed, then it is probably ok.

I don't have a 6pin connector but The card is coming with a 6pin connector.
