Need to finalize PSU

post #1 of 7
Thread Starter 
Gonna be SLI'ing 2 560Ti's in the near future and I know 650W is more than sufficient...HOWEVER suppose I wanted to SLI the next generation GTX 670s much later on...would the 650W still most likely be able to support that?

Cause I have narrowed down my PSUs to these:

Antec HCP750, $209
Corsair HX650, $163

A lot of people would say just get the HCP750 for future-proofing, but I've seen the PSU gurus Phaedrus and TwoCables say that this thinking is flawed and on more than on occasion suggest to others to just get the lower PSUs.

Thoughts?

Well I can say for sure that 650 is fine for 560tis, And I would guess that it would do for 670 series since they are using smaller nm chips that should require less power.

Alright thanks a lot guys HX650 it is

Btw, can you SLI cards from different manufacturers? Like I'm getting the MSI 560Ti Twin Frozr II 2GB now and waiting about a year or so for the price to drop really low...in the off chance I can't find the exact same card could I just use another 560Ti or is this a really bad idea?

If it's a bad idea...I might as well sport the extra $$$ now and go for a 570 right?

Different manufactures are fine, however if you purchase one that is 2gb, make sure the other is 2GB aswell.

You could always go for a single card like the 570, which is more powerful, then you could indeed SLI that in future, however you would need atleast an 750w PSU.

Thank you!

Just another question, I hear that the 3GB RAM for 580s or 590s isn't really a true 3GB (it is actually dual 1.5GB VRAM). Now about the MSI 560Ti Twin Frozr II 2GB...is that truly 2GB VRAM? If so, wouldn't that make the 560Ti's having the most useable VRAM of all cards currently? Seems odd + interesting at the same time.

But I also seen people say BF3 can memory leak/use up to close to 2GB VRAM...and they're using 570s or 580s? confused.
