Upgrading from Gainward GeForce GTX 560Ti 2GB Phantom to MSI GeForce GTX 760 2GB - Hardware & Software

Hello. I've just decided that I want to upgrade from my [URL="http://www.gainward.com/main/vgapro.php?id=458"]Gainward GeForce GTX 560Ti 2GB[/URL] to [URL="http://www.msi.com/product/vga/N760-TF-2GD5-OC.html#overview"]MSI GeForce GTX 760 2GB[/URL] and I have a few questions regarding it. Right now, my current setup is as follows: [URL="http://ark.intel.com/products/52214/"]Intel Core i7-2600K @ 3.4 Ghz Quad Core[/URL] [URL="http://www.msi.com/product/mb/B75MA-P45.html"]MSI B75MA-P45 Motherboard[/URL] 2 x 4 GB DDR3 Corsair Dual-Channel RAM [URL="http://www.gainward.com/main/vgapro.php?id=458"]Gainward GeForce GTX 560Ti 2GB "Phantom"[/URL] [URL="http://ocz.com/consumer/agility-3-sata-3-ssd"]1 x 120 GB OCZ-Agility3 SSD[/URL] 1 x 500GB Seagate Barracuda HDD 7200rpm [URL="http://tech-reviews.co.uk/reviews/silver-power-sp-ss500-power-supply-review/"]Silver Power SP-SS500 500W PSU[/URL] Now, my question is if I am able to upgrade to this new graphics card with the current power supply that I have? I have a feeling that 500W is not enough to fully power it. Am I wrong? According to the place I'm going to purchase it from, a minimum of 500W PSU is enough, but I'm still unsure.

That GPU and CPU has a TDP of 265w, so you are left with 235w for the rest of the system. So you should be fine, but if you wanted to have some head room you could get a 550-600w, but I fairly certain that 500 will suffice.

I also purchased a new PSU; Corsair 750W I'm looking forward to changing the PSU, I've never done it before.

While your CPU has a TDP of 95W, they're known to pull up to 150W under certain loads. The GPU has a 170W TDP, but that's only at the recommended GPU clock (980 MHz), the card you picked is factory overclocked up to 1150 MHz, which causes the TDP to go up considerably. The PCIe slot can deliver 75W, plus the 8 pin and 6 pin PCIe power connectors (150W+75W) allow the card to draw up to 300W, which isn't unreasonable in certain situations. Worst case, your CPU and GPU together can pull 450W, which combined with the other things in your system would push it over the 500W your PSU can supply (assuming it's a quality unit that can do what it says.) I wouldn't go with less than a 650W PSU in your case to be on the safe side.

I figured this was the case, so instead of purchasing the hardware specified in the first post, I ended up purchasing the gear in the 3rd post. Do you think the new 750W PSU would be sufficient to supply the 770 GPU along with the rest of the hardware. Not to mention I have a TV attatched via HDMI and a my normal monitor, "glowing" keyboard, and a "glowing" mouse, an external HDD on 2TB, headset and a 5ch surround. Of course, most of these has their own power supply, but I'm guessing it can be good to take into the whole calculation.

The 770 has a TDP of 230W at its base clock (1046 MHz.) The manufacturer of the card probably has it overclocked still, which pushes the TDP upwards. The card probably has two 8 pin PCIe power connectors so including the PCIe slot (75+150+150) you get a maximum power draw of 375W. Including the CPU and GPU, you'd have a maximum theoretical power draw of around 525W. Plus other components we can toss in an additional 125W to be on the liberal side for 650W. A quality 750W unit should be fine.

Thank you GiGaBiTe for your help. Very much appreciated!

And if that PSU is modular then remember you might not need all cables.

750W is more than enough for a single 770. You can SLI on a 750w PSU just fine. I too have a 750w psu and it was completely fine with my 2500k at 5ghz and a OC'ed 680 + OC'ed 670 in SLI. (driver hack, I know it's not officially supported)

Alright, I've now installed the new PSU & GPU and everything seems to work. What I don't like though is that from the looks of it, my Gainward GeForce GTX 560Ti is operating better than this MSI GeForce GTX 770 TwinFrozr (OC'd version) graphics card. Any clues why?

[QUOTE=RandomGamer342;42829458]Have you done a clean reinstall of the newest drivers?[/QUOTE] Yeah. Before I did anything I uninstalled all graphics drivers and then i put in the new GPU along with the PSU. After that I installed the drivers from the CD and tested it with a result of low performance and after that I ran an update through the NVIDIA control panel and it updated the driver but the result stays the same; low performance.
