I just bought this to test my power supply. I just want to know if this can be tested with and without my 7970 connected to psu?

ok now I understand. just unplug all connections to your system from the power supply, connect all you can to the tester , the tester will power up the power supply and watch the screen , just to ask what size power supply is it and what brand?

what is a 7970 ? this tester works great connect your supply to the tester and plug in the power supply and it will tell you all the out puts and light up red if not up to factory out put spec's, won't tell you if the power supply is over heating that's something you will have to be sure the fan is working and its not clogged full of dust.

You couldnt run one 7950 on your 700 watt psu? I can run 3 of these 7950s with my power hungry 8350 cpu at around 750w. So one 7950 should work fine on a 400w psu.

I am using a 650wattt power supply. The card needs a power source other than the mainboard.

Don't know exactly. Information should be available from video card maker. I am using with a 380W power supply with no issues, but also no gaming. HTPC application.

Yes, I powered my 7870 with no problem. It requires 2 of 6 pin connectors as well.

Im running mine with a corsair 750 w power supply and it is running fine. Im not one hundred percent sure but maybe give pcpartspicker a try and just put what you have andd the graphics card to the build.

Hi dude, the box says: "500Watts or greater power supply". If you have a certified (real) 500W PSU, you'll be ok.

I don't know what your entire system power requirements, but unless you have a ton of extra equipment running you should be fine with 750 watts. I'm running that gpu with a 650 Watt power supply and have zero problems.

This power supply will work. I suggest getting a different power supply like Corsiar, Evga, or rosewill. Try and find one that is 80+ certified. I don't recommend this power supply.

Ive ran this with 2 7990s and 1 R9 290 and its gotten fried two times. Yeah had to get an RMA twice. I had to buy another power supply and run them both together jumpstarting the other one.

Yes. I am running it just fine off a 650W PS. Make sure its a decent quality Power supply though.

Richard, if you go to device manager you'll see that there are 2 video card. One for low power consumption and the 7970 for aplications that demand much more power such as games.I sugest you download latest version of ATI Catalyst and set up your video and power saving preferences. Also using that program you can safely oveclock you processor and start getting great performance. Dont know why it comes with power saving preferences when you first open the lap.

The TDP for a GTX 780 is 250W. Unless you're running a LOT of hard drives or some cpu with a huge power draw, you should be able to use this power supply with power to spare. I think it's unlikely that the rest of your pc is using 250W. I am running a crypto mining system with 4 video cards (each with a TDP of 150W) with this supply and it's only pulling 700W from the wall. Let's assume about 15% efficiency lost to heat so.....that implies that the system itself is actually only drawing about 600W from the PSU.

You can get all the specs here:http://us.msi.com/product/vga/R7950-TwinFrozr3GD5-OC.html#?div=Specificationin fact the card is about 10.25" & the PCI connectors are on top so cabling will not add to the length. I don't know about the 7970 pcb.

This graphics card manufacturers specifications call for a minimum power supply of 500 Watts. In the real world I would suspect that if you have a quality power supply of at least 350 Watts it would probably work. That being said, a 350 - 450 Watt power supply may fail at anytime or prematurely. Additionally, no secondary power connector is required...just the PCI Express slot on your motherboard. Good Luck

My power supply is similar and I have been using it for about a year now with no issues. I also use dual monitors. I'd at least try it out.

No. It requires at least a 600 watt power supply. See: http://www.geforce.com/hardware/desktop-gpus/geforce-gtx-780/specifications
