Hi,

I was planning on adding another 4870 to my current setup.

Unfortunately my current PSU (sig) only has 2 x PCI-E 6-pin connectors.

Do you guys have good suggestions for this kind of a setup?

I've heard a lot of good things about the PC Power & Cooling Silencer 750w and the Corsair TX750.
The only problem is, that I like my current modular setup quite a lot, so I was planning on getting one for x-fire.
I'm also looking at a single 12V rail, since those seem to get a lot of recommendations from people.

Thanks in advance.

Edit: Sorry if this was the wrong section, but I'm also overclocking my cpu to around 4 GHz and both graphics cards cooling them with Accelero twin turbos.

Thanks both of you for the suggestions. More are appriciated.

I'm a bit sceptical about the Ultra, they have a bad name. I've been consulting this a lot:

Also the Decathlon is a bit expensive here in finland.
I could get the Corsair or PC P&C for 40€ less (of course, non modular, but still).

Keep 'em coming :)

those are good choices but not modular though. In regards to Ultra PSUs, you are right, some have been not as reliable but the X3 line that i recomended are top notch and received rave reviews. Anyway, good luck on whatever you decide.

Actually the ultra x3 has gotten a lot of great reviews, but I went with the corsair 1000w trust me, for the next 5 years this should handle everything you can throw at it and more if not, well theres always those 30 new nuclear reactors the gov is building.
