Question about NVidia 750Ti with 6pin connector


Recommended Posts

Greetings,

 

I'm interested in buying this card: http://www.evga.com/Products/Product.aspx?pn=02G-P4-3757-KR

 

Most of 750Ti cards need only 60 Watts to run. This one needs 85 Watts and that's why it comes with a 6 pin power connector.

 

I've read somewhere that the reason for the 6 pin connector is to provide extra power in case the card is overclocked.

 

Here is my question, Will this card run at 60 Watts if I don't overclock it?

It's overclocked to begin with. Base clock on that card is 1189 MHz, and boost clock is 1268 MHz. The reference 750 Ti is rated for 1020 MHz base clock, and 1085 MHz boost clock. I would plug in the 6 pin power connector, otherwise look for a different 750 Ti/card.

What are you worrying about? Is your PSU too small? You need all 6 pins to run it, or... it won't.

Thanks, that's the answer i was looking for.

That is because the amount of power the card needs is greater than what it can draw via the PCI-Express bus.

 

There ARE GTX750 cards that use only the power available via the PCI Express bus - or less; I've mentioned the ASUS GTX750 DIrectCU Silent several times.  It is clocked dead-stock, and uses less power than a reference GTX550Ti; rather amazingly, it also has no fan.  (The Silent is a full-length dual-slot GPU - like most - but not all - GTX750/Ti-based cards.)

 

The reasons I'm considering it are pretty obvious - a stock GTX750 suits my needs just fine - therefore, I don't need a power pig.  (I have a GTX550Ti currently; the Silent outclasses it, while using less power.)

The GTX550Ti requires an adapter for standard HDMI-out (it has a mini-HDMI port) - the Silent has a standard HDMI port.  (It also supports 4K over HDMI; again, GTX550Ti doesn't.)

It is now a direct swap - remember, Windows 10 IP is my main desktop OS.  (I won't even need to change drivers; shut down, swap GPUs, reboot.)

New and at retail, it costs about $140USD locally.  Open-box and refurbished models are in the $100 range.  (Therefore unpricey.)

If I remember correctly all gt*40 and below don't need external power besides pcie (I owned a gt440 before).

I ended replacing my psu when I got a gtx660, replacing the psu was far easier then I expected.

Hey guys, since we're on this topic - can you tell me how would the video card behave if it is underpowered? 

 

I have a 560 Ti.

On nVidia's website. they say the minimum power requirement is 500W, and I have a 500W PSU. However, since I installed this card my CPU runs about 10 degrees celsius hotter and I'm not sure if the 560Ti is running at the normal idle temperatures.

You are on the edge - that is likely why the CPU is running hotter, it is having to do more work on less power.  (The issue is probably NOT your newer GPU per se, but likely another power pig in the system - such as an older platter drive.)  Consider upgrading to a 600W PSU at minimum.

That's why one would get the 750Ti. It's power requirement is 300~350W. Far less (40% less) than the 560Ti, and it'll run faster. And it's Maxwell. The 750Ti's that Mindovermaster and I both have are the 2gb varieties, and (as a side note) they are Linux-compatible with the Xorg-Edgers PPA enabled. :yes:
