Hello guys , i'm building my own rig but i got a problem choosing a PSU.
I got the AMD FX-8120 chip, 8 GB of ram, 1 HDD 500GB drive,and I will use 2 HD 7770 (i got 1 and i plan to get a second one).
I am planing to buy them from amazon uk as it oly ships to my country. I have picked those 2 PSUs and i need your recommendation .
1)Antec EarthWatts Green Series EA-650 650W Power Supply Unit - http://www.amazon.co.uk/Antec-EarthWatts-Series-EA-650-...

2)Zalman ZM600-GT 600W ATX Power Supply- http://www.amazon.co.uk/Zalman-ZM600-GT-600W-Power-Supp...

Sadly my budged will be around 60-70 pounds so i need a good PSU with less extras but that will support the future Crossfire mod and will have some power for OC-ed CPU.

Could you give me a link to Rammy's choice of OCZ ? I'm quite new to the forum. Thanks in advance.

Sorry, I mis-typed. I meant to say the Xfx 650W PSU. I confused this post with another I was working on.

That would be fine. I have used and liked all the Antec PSUs I've had. But remember, with that unit you will be limited to 2 cards that only require a single 8/6 pin PCIe pwr cable each (like your 2 x HD 7770s) or a single card that takes 2 8/6 pin cables. Not an issue probably, just thought I'd mention it. Oh, and remember that it doesn't come with a power cable. They assume you will be using your old cable.

What do you think about this one: Corsair TX650W V2? I can't find what type of connectors it has and if it could support crossfire of 2 7770s.It seems to be quite a deal.

Best solution

Corsair TX650 V2 has been discontinued, which is perhaps why there are deals to be had.
It comes with 2 (6+2) PCIe connectors which is perfectly sufficient for 7770 Xfire.
It's a good unit, if it's on offer for a good price then definitely grab one.
