750Ti Low Prof

Hi all,

I currently have a sapphire HD7750 overclocked in my HP8000 elite machine that hosts a few websites and some other bits.

It is used occasionally for LAN gaming if a friend or guest comes over.

I've just seen these:

http://www.overclockers.co.uk/showproduct.php?prodid=GX-058-KF

And drooled a little! It seems very nice for a low profile card.

Knowing that the 7750 draws 55w from the 75 available in the PCI slot and my computer still seems to take it I wonder if the 750 will be ok? From doing some research it seems it should draw a similar amount, although of course is limited by the 75w PCI allowance anyhow.

I've contacted overclockers and I am hoping they will come back into stock.

I've also been looking at trying to upgrade the PSU as it is on the limit at the moment although seems to be coping well, but options are limited.

The machine does only run an e8500, two usb devices and two sata drives, thoughts?


Cheers!
 
I think the 750Ti draws about 60w and so I think you should be OK. As it stands, it is the fastest bus-powered graphics card available.

Watch out that although it is a low profile card the cooler is a bit chunky and so may require more slot space than your current card.
 
Brill thanks guys, I did think the cooler looks quite a bit fatter than my 7750 so will check when I get home.

Diddums, spot on and detailed info there, thanks very much!

The Small Form Factor, even though only had a 240w PSU from factory came shipped with a less efficient (processing power to power consumption ratio) 1gb HD4650, which I understand was spec'd at 55w on the PCIE lane.

Games aren't played on it often, perhaps a few hours an evening maybe every other month, so it's not going to be used to it's limit on a regular basis.

In honesty, there is no real need to upgrade, but I saw that little card and thought it looked pretty awesome and would add a little extra oomph for when someone uses it for lan games.

I'm just waiting for OCUK to come back to me and let me know when they can get one :)

Cheers!

You should definitely see some improvement going from the 7750 to the 750Ti, but do bare in mind that your stock clock E8500 would still be the limiting factor for frame rate most of the time with dips cannot be avoided at intensive scenes.
 
Thanks for that, yes the e8500 I forgot will be holding back CPU intensive titles.

Hmmm, I wonder how much of a bottleneck it will be.

I did see FPS gains with an OC of the 7750, so I guess there is still room for performance improvement in 3D heavy games.

I just also decided to get a power meter to do some power testing, and I am surprised by the results:

IDLE = 55w from the wall average
Normal windows tasks and browsing etc = 60-70w
TombRaider 3 bench on high = 115w
OCCT PSU test = 150w

I expected around 180 or more from the current set up, but I guess that would be with both SATA devices at full load as well which they were not.

I checked clearance in the case and there is plenty :)

Hoping these come back in stock ASAP and I will order one up and then flog the 7750. The 7750 is still a great little card though, as an example TombRaider 2013 benchmark with everything on high sees 28fps @ native res of the NEC which is 1680x1050.

Pleased with the results of the power test, this was also with the keyboard fully illuminated and the USB speakers on full.

I just remembered I need to be a bit careful when I do get one of switching from AMD to Nvidia on the OS. I guess a careful un-install of the drivers in safe mode is in order.

Cheers guys!
 
Just swapped out the media / game storage drive from a WD1600 with a 9.5w read / write and 8.75w idle requirement to a 500gb WD Scorpio black 2.5" to save on heat and power @ only 1.75w read / write and 0.8w idle to help things too :)
