570GTX SLI, BD-ROM and More, whats PSU wattage

[bora63]

Hi guys,

Planning new build, will have a single 570 GTX to start with a single Sata III HDD, BD-ROM, i5 2500k, and possibly a few cathodes, BUT plan to add a second 570 and a SSD and RAID settup.

So will a 750W PSU suffice or will I need to get a 850W?

I did a online checker and it said I need like 800W but I did include a lot more fans and other periphals that will not be needed now

Thanks

If your overclocking heavily, you should go with a 800+.

Otherwise a 750w would be ok.

I think that a 750W PSU would be perfectly fine, even with lots of overclocking.

Depends on the 750w unit but it should work fine. Don't go extremely crazy with overclocking though just for a bit of headroom.

A good (80 plus rated) 750w would be ok. If possible though, stretch for a 850w.

Yes most likely a good 750w would be fine, but Guru 3d suggests 800+ if overclocking on a high end system.

Make sure it has enough connectors to run SLI, I don't think my 750 does.
