Power Supply Clarification

post #1 of 12
Thread Starter 
Just a few questions I thought here might be a good place to try.

How many pci express and what type does the CX 750 have? New egg list 4x6 pin the corsair site says there are two connectors.

Is this power supply a non-modular version of the smart 750. Would it work as well or better?

Well first, my question is, what are you powering that you need a 750W power supply for?

There will be a i5 in my system and I want to do a dual sli or crossfire. With a card in the 200 to 300 range.

Oh, then all you need is a quality-made 650W PSU - and this isn't the minimum either.  It's just that it's easier to find one that has 4 x 6+2-pin PCI-E cables that doesn't break the bank.  For example, the Rosewill 650-M is a high-quality modular PSU for only $104.99 shipped:  http://www.newegg.com/Product/Product.aspx?Item=N82E16817182263

What kind of cards actually use 8 pin. I did a quick glance at the ati cards in the 7000s range on newegg. None of the cards in my budget used 8 pin, either 6 or two 6 pin. I'm starting to think the 8 pin is not needed.

The PCU your recommended looks good. It is more expensive than the ones I was looking at before. Though its 80 plus gold.

The 80+ Certification is just marketing hype.

 

Having 4 x 6+2-pin PCI-E cables is nice just in case you upgrade to cards that need them.  Such cards today would be like the GTX 680 and the 7970 for sure.

 

Anyway, it's nearly impossible to beat the 650-M at this price because of the quality of the unit.  Rosewill used the Super Flower Golden Green Pro to make the modular Capstones.

 

However, is $104.99 too expensive?  I mean, there are non-modular PSUs that are just as good but cost less.

If its possible I could also get the rosewill hive 650 and add in two PCI express cables. If that would work if 650 is all that is needed for two GPUs

I'm first concerned about quality and second price

Edit:
Never mind looks like switching modular cables is a big no no
Ill have to look more into PSU in the 650 range with 4 PCI express. I just thought of going to this site. So I haven't had to much time to look into here.

The rosewill hive 650 cannot have 4 6+2 pins. I bought the 650 and newegg advertised it as 4x6+2 pin but it only has 2. Luckily I was only using a 660ti in the build i was working on.

I'm first concerned about quality and second price

 

If you are free to be concerned about the quality before the price, then the Capstone is a better choice than the HIVE series.  I know that the HIVE series is on the recommended PSU list (here), but I don't remember what PSU Rosewill used to create it.  However, I do know that it's inferior to the Capstone.  When I forget how the HIVE rates (and I do tend to forget how it rates), I'm reminded by the fact that its continuous capacity is only rated up to 40°C.  It could be worse and it could be at 30°C, but 50°C is much better.  This rating means that as long as the temperature stays below the rating, then the PSU can continuously deliver its rated wattage.  As the temperature goes above the rating (be it 30, 40, or 50°C), the continuous capacity decreases.

 

So this means that if the 650W HIVE's internal temperature exceeds 40°C, then it is no longer able to continuously deliver 650W.  Although, I don't know how it scales;  I just know the basics.

 

Still, even having said that, I guess I would recommend the HIVE if the price is attractive.  Although, the non-modular Capstone is only $7.01 more than the HIVE at $89.99 shipped:  http://www.newegg.com/Product/Product.aspx?Item=N82E16817182071

The HIVE series is OEM'd by Sirtec, and it is inferior to the CAPSTONE series.
