GTX 750 Taken Apart, Sips Power from a Single 6-pin Connector
Here are the first pictures of a partner-branded GeForce GTX 750 graphics card taken apart. It reveals a couple of things - to begin with, the GM107 silicon will bring about some genuine performance per Watt improvements, despite being based on the existing 28 nm silicon fab process, and second, that cards based on the chip will be extremely cheap to build, giving NVIDIA a good chance to strengthen its position in the sub-$200 market segment. This particular card is cooled by a simple fan-heatsink that's essentially a chunk of metal with a fan latched on to it. The card relies on a simple 2+1 phase VRM, which draws power from a single 6-pin PCIe power connector. NVIDIA is expected to launch the GTX 750 and GTX 750 Ti a little later this month.

We might well see "Ti reference" models with no 6-pin, more a way that AIB's can then substantiate/differentiate their more custom OC'd versions. Go with reference and be assured it only ever be a "plug and play" card, while then the FTW, AMP, Super Clocks, etc offer the bump that’s so lucrative for those AIB’s.
1. The reference specification does not require auxiliary power, and AIB's are at liberty to add at their discretion, or the extremely unlikely,
2. The reference card requires auxiliary power and some AIB's are manufacturing cards with power circuitry LOWER than Nvidia's reference design
Which would you think is more a more likely state of affairs?
I'd also add that, while adding a 6-pin auxiliary power input is for some reason deemed a crime against humanity by some people, isn't it better that the vendor is allowing custom implementations from day one?
All in all, except for the immediate availability it doesn't seem very far removed from, say, the HD 7970/GE (for example) - there are more than a few 2 x 8-pin varieties of proprietary designs, and the reference board even has solder points for 2 x 8-pin input, yet I never saw a whole lot of howling about the need for 375W input power for the card from the same people who see the incorporation of feature set expansion options with this card as a negative. How curious.
700 series is going to be hella confusing with Kepler parts filling in the top and Maxwell parts at the bottom.
ASUS might be re-using one of their 3 650 PCB or its photoshoped since the cooler looks nothing like a Asus design
Either way. It will be like the 650. Some had 6pin connectors some didn't. Nvidia recomemded one even when it was set at 64w TDP
Welcome to the synthesis of marketing and random number generation.
:rolleyes:
2. It is common that if a card is close to a power bracket edge to include the next size up.
Without it Overclocking would suck and low end motherboards would be strained etc ...
Anyway if you want an answer you should see all the (wrong) info about the cards that was all over the internet the last 10 days pointing at a 960 cores card with no 6pin connector. A month ago when info was very limited I was expecting a card that wouldn't be much different than Kepler because of that 28nm process. The last 10 days wrong info was spread and maintained on the internet with multiple articles, sources, gpuz screenshots and pictures of the cards, so the expectations where totally different. In the end it seems we will end up somewhere in the middle.
...but then is used as a basis for screeds of supposition on a supposed lack of efficiency for a GPU whose raison d'être is efficiency. Of course when it is the same people being overly pessimistic regarding one vendor, and wildly optimistic regarding another, it becomes kind of an armchair sport guessing how far off the mark their next pronouncement is, and how long they keep to their original position in the face of mounting contrary evidence.

60W for 750Ti at 28nm is really a huge step forward.
1200+ MHz core / 6400 MHz effective memorywith no auxiliary power input. Not too shabby.

Whats troubling is the first picture. Look at the price $199.99 OUCH!!!!
With the R7 260X OC going for $119-$129. A $70 more then 50% difference is too high.
Good eye on that $199 price, yikes! o_O
The card was purchased from Micro Center - not the cheapest outlet for graphics- an R7 260X will cost you $145-155
MicroCenter OH - Cincinnati/Sharonville - MSI GTX750TI OC TF 2GB D5 DVH $179.99 w/$20.00 discount
