Hi ,i am looking to buy nvidia geforce gtx 750 ,i have this smps (http://i.imgur.com/RXwDzeU.jpg), needed to know if the gpu needs to be connected to smps or not.Also need to make sure how much does that psu give usable watts.What does that +12v1 and +12v2 means?

My Rig:
Intel I5 4670 4th generation
6 GB ram
H81M-S1 motherboard
500Hdd

the GX 750 can run off the motherboard power through the PCI-E slot, no power connectors required.

As for the power supply all you need is 400W with above 20A is easily sufficient enough.

"What does that +12v1 and +12v2 means?" <- don't worry too much about this, for an example a power supply has 12v1 with 12A and 12v2 with 19A, it has 31A total.

it is unknown, though i doubt it will deliver 450W.

I would go for a PSU that fits into these three categories -

Cprsair/Antec/XFX/Seasonic with at least 80+ BRONZE Certification and a minimum of 5 years warranty. If above 400W your easily set and looking at something quality.

Probably, but still it's not correct.
Currents given on multirail PSU's are limits, not actual currents.
If a PSU has say 20 A each on 2 rails, then I personally assume each can supply only 80% of what is written, so total current is 2*16 = 32 A, not 40A as you'd get when you add them.
