Need help with a psu

[ThePotato]

So im looking for the right psu for me, i have around £80 left to spend.

Specs:

CPU: i-5 2400 quad core 3.1 ghz
GFX: gtx 660 oc direct cu ii 2gb (sli in the future)
Motherboard: AsRock B75 Pro3 micro atx
Ram: 8gb kingston 1600 mhz

I want around 700 - 800 w to future proof the build. Thanks for any comments in the future!

The ASRock B75 Pro3-M doesn't support SLI, so you would have to upgrade the motherboard first.

The first requirement for a PSU to power GTX 660 SLI is two PCIe connectors.

Also you don't need as much as 700-800W for GTX 660 SLI. Wattage isn't too demanding because GTX 660s are rated for a TDP of 140W. Reviews which measure GPU only power consumption typically show them draw between 129 and 137W.

Seasonic G-550 is probably the best you can do for £80 and what I would recommend, unless you are wanting to keep the options open for a much more power hungry build in the future.
OTOH there aren't many good 700-800W PSUs for £80. The In Win GreenMe 750W unit is the best one that I can see.
