Best Nvidia-SLI ready (GTX670) PSU? OCZ StealthXStream 600W enough?

timmymagic07 · 21 Jul 2012 at 11:13

Hello,

Currently I am running with a OCZ StealthXStream 600W PSU I bought back in 2007/2008, which has done a stellar job of keeping my Q6600/8800GT setup running ever since.

Now I have upgraded to an i7 2600K with a GTX670, with the idea of doing SLI within the next couple of months. Having looked at the connectors, it is clear OCZ haven't put four PCI-E connectors on this PSU, making me question the idea of using it for this new SLI config.

I have ready 600W should be enough, but maybe with little juice remaining. What is the the general consensus here? Is it enough or do I need more?

If I need more, what is the best bang for buck PSU that will be safe? I guess my question is really, what is the cheapest decent quality PSU I can buy that will be enough to power them both?

Any help would be greatly appreciated

I would not advise that. It's not just the power on the box, but how the power is delivered.

Ideally, 750W, 4 PCIE connectors, like the Corsair TX750M (ChannelWell), XFX 750W xxx or Black (Seasonic), OCZ ZT 750W (Sirfa), Antec High Current Gamer 750W (non-modular, Delta Electronics), XFX Core 750W (non-modular, Seasonic). In the order of personal preference.

Bascially, £75-£85.

680 sli (similar to 670 sli overclocked i suppose) runs at 536w total load, your poor 600w psu will curl up and shrivel ;p
ya 750w would be ideal

Do you need SLI anyway? If you don't save your money or do something else with it. But if you get a new 670, you will need a new PSU.

Hello, thanks for the replies,

Yeah, I have a 30" monitor, so another 670GTX would future proof me for a few years. The last time I upgraded was in 2007, I do not envisage upgrading again for many years, if at all, what with the likelihood of growing out of gaming in the next 5 years (does this ever happen though? I'm 28 now!).

It is a good question though, I think the more prevalent question is whether I can be bothered to take out my old PSU and put in a new one, bit of a hassle! With a fully modular PSU I could be interested mind, I will have a think over the next couple of weeks and decide.

Many thanks guys

Don't buy another one for the reason of future proofing, buy another one when you actually need another card- that way they'll be cheaper.
