Hello, :wahoo: 

I wannna get a PSU to support my new build, with a gtx 560 ti, which I will SLI with another 560 ti in future.

As I can see from the geForce website, a single card needs minimum 500W power supply with two 6 pin connecters. I was looking at corsair PSUs but they only have 4 pin connectors. :??:  I dont get it, how cud they not have power supplies with 6 pin connectors? :heink:  Although it lists two PCI-E connectors. Is that the 6 pin connector?? :sarcastic: 


Anyway
If not corsair, what brand and wattage should I go for getting a GTX 560 ti SLI? I think it has to have at least 50 amps on the +12V rail. So what do you all suggest??


Thx in Advance!! :D

Hello gam0reily;

All the Corsairs have 6+2pin PCI-e connectors. You might have looked at one of the other PSU power leads.

To get the 4x PCI-e power leads you want you could go with:
CORSAIR Pro Series HX650 650W 52Amps +12V and 4x 6+2pin PCI-e power leads.
CORSAIR Enthusiast Series TX750 V2 750W 62Amps +12V and 4x 6+2pin PCI-e power leads.

Corsair has a special 15% off w/ promo code EMCNFJG23, ends 4/19

a 700w is recommended-

GeForce GTX 560 Ti in 2-way SLI

A second card requires you to add another ~175 Watts. You need a 700+ Watt power supply unit if you use it in a high-end system (800+ to a KiloWatt is recommended if you plan on any overclocking).

i would suggest nzxt hale82 750w-

it's SLi ready,modular and high quality(rebranded superflower i guess).for $90 it's a sweet deal.

Actually it is the same as the Corsair TX750 V2, XFX Pro 750W Core Edition (minus the modular interface on those two) and Seasonic M12II Bronze 750W.

A pair of 560ti will generate a lot of heating inside your case, so you will need a good air flow, thus it is recommended to get a modular, or a semi-modular PSU like:


CORSAIR Enthusiast Series TX750M 750W ATX12V v2.31 / EPS12V v2.92 80 PLUS BRONZE Certified Semi Modular http://www.newegg.com/Product/Product.aspx?Item=N82E168...

or

CORSAIR Professional Series HX750 (CMPSU-750HX) 750W ATX12V 2.3 / EPS12V 2.91 SLI Ready CrossFire Ready 80 PLUS SILVER Certified Modular Active http://www.newegg.com/Product/Product.aspx?Item=N82E168...

How does a modular PSU use less cables to power the same hardware as a non-powered modular PSU?

The 750w Corsair should be fine. You'll have plenty on the rails as well as some decent overhead ( not necessarily overkill that I am known for on the forums I moderate ). : D

How is a corsair GS 800 (non modular) in comparison with the TX750.
I am getting it for less.

It's basically got every thing the TX750 V2 has and a bit higher +12V rating 65Amps vs 62Amps for TX750.

That's a good deal if you're getting it for less than the cost of the TX750 V2.
We're seeing the GS 800 going for $25 more than TX 750 right now.

Corsair PSU comparison: TX750 V2 + GS 800W

All you really need is 750 watts. 800 or 850 is where Your high end Graphics cards start getting SLI'd. Corsair makes a Fully modular AX or HX power supply family that has the watts you need!

The cables that are not to be used by a modular PSU do no need to be in the case, while cables in a non modular PSU remains around blocking the air flow -- so a modular PSU uses less cables for the same amount of hardware.

That´s why I recommended the OP to get a CORSAIR Professional Series HX750 (CMPSU-750HX) 750W ATX12V 2.3 / EPS12V 2.91 SLI Ready CrossFire Ready 80 PLUS SILVER Certified Modular Active http://www.newegg.com/Product/Product.aspx?Item=N82E168...

If you're not using a cable - you tuck it away out of the air flow.

I know that's 'old school' cable management - but it has the same benefit.

Yea if you absolutely have to get a modular PSU and can afford it, Get it. But if you can't old school cables management is the way to go!

Well, I am not averse to cable management, so I think I wud go with the GS800.
