It is recommended by AMD that you use a 500w PSU with at least one 6 pin connector. But some times you can get by with how many amps are on the 12v rail. But looking at that PSU I don't think it is going to cut it.

I can't find anymore info on it other than your link. You can look on the sticker on the PSU and look for numbers that look like this 3.3v = 13a + 5v = 14a + 12v = 16a. And write down all the numbers and share it with us.

But I really don't think it will do the job. I don't see anywhere that you have a 6 pin connector that needs to connect to the GPU in the pics of the PSU. You may not be able to get the brands that are good over in India.

But if you can look for Corsair, Antec, Seasonic, XFX, Siliver Stone, and some OCZ models. I know the cost over there is very high but the PSU is the most important piece of hardwear.

With out it you have nother but a PC that won't work. If that PSU so burn out it will or could take stuff with it leaving you with a bigge bill and nothing to have fun with. I hope this helped and I really do wish you good luck on this issue.

+1^

I also checked out the PSU you linked. It stated at a rated 68% efficiency. That is really bad. You may not even power the card, let alone the system itself.

Also, can you list out the other specifications of your computer?

Not too sure how many amps are on the +12V rail.

A 7750 will most likely work since a full system load is around ~215 watts.

But, I know for sure a 5450, 6450, GT 430 can definitely work.

Best solution

Yes your PSU of 450w will work on the 7750 It calls for a 400w PSU to do the job. That PSU might be a 450w but that probably is the max it can put out. I would say that is pushes from 350 to 450.

It is probably not a constant power. But I would say it is safe to get it but be very careful with that PSU. We are only trying to help and we don't want to see anything bad happen to anybodies rigs.

This is why we let you know this stuff. I wish I had someone to tell me about my bad PSU and my GPU's but I didn't and now I have to live with my choice and I have to be very careful with my PSU.

Anyway I hope this has helped some and good luck to you.
