I need a PSU for an i3 2120 on a Asus H61, the GPU will be either Radeon HD 6770 or 6790. Planning to use 2 HDD's and a DVD RW.

The problem I face is that it will be hard for me to find good Antec or Corsair PSU's right now, but it will be very easy to choose 1 from among these http://www.czone.com.pk/power-supply-pakistan-ppt.183.a..., not heard about any of these brand before now so please advise.

Thanks

This is the cheapest one on that I would use:
Cooler Master GX 450W Rs. 5,000.00

However it is not really suitable for a system with a 6790 because the 6790 needs two 6pin PCIe connectors, while the GX 450W only has one.

The 550W version does have two PCIe connectors.

All the HD 6790s here is the US I've seen only require 1 6 pin PCIe power connector. Are they different elsewhere?

OK. I see why they might say that now. I found some HD 6790s that were OC'ed that required 2 6-pin connectors.
Example: http://www.newegg.com/Product/Product.aspx?Item=N82E168...

But it's stock counterpart only requires 1: http://www.newegg.com/Product/Product.aspx?Item=N82E168...
