I only have a 450 watt (peak 500) power supply in my tower. Will this card still perform?

Hi robert,Sorry for the delay, I used a watt meter to see how much my system was using. I have a big CPU cooler and this graphic card and I was reading 300 or so watts at the wall receptacle. I lean the way of others. While you could probably get by for a while with your power supply, solid voltage = stability in the computer world. If your PS is always near its limit, you may run in a lot of issues. A PS is fairly cheap and easy to install. I have a seatronic 750 S series to give me room for expansion in the future but it may be an overkill. A good 650 would be just fine for sure.Regards Hi robert,Sorry for the delay, I used a watt meter to see how much my system was using.

You should get a 500 watt power supply or you will cook your power supply as it will operate at its PEAK for extended period of time.

You might be pushing it, depending on the other hardware your system has to keep powered on. I'm running it with a 500 Watt XFX Bronze rated and have no issues.

It should work, if anything, at least make sure your PSU is reliable. I had this card running with a 65W CPU on a 300W PSU

Hey Ronel, I have a 750 watt power supply that I am using with this card. However, a standard power supply one with no less than 350 watts should be enough to run the card with no problems. I would recommend getting a 400 to 450 watt power supply if you will be using this card for gaming.

It depends on how many other things you have in your system, but 850w should be more than enough. I'm running my card on a 550 W PSU right now. As long as you have the needed power connections off your psu you are golden.

400 watt or greater is the recommendation for this model. You should calculate how your psu is destrobuting it's power to make sure you can delegate enough to the card

I have a 430 watt PSU, and it runs perfectly. Those recommended wattages are usually overstated.

No, I wouldn't recommend you use this card with such low PSU. If you can't upgrade your power supply I would go with a 7750 instead. It would be better if you upgraded the power supply and buy a better card than either though.

Assuming you're not running a bunch of other stuff in your computer along with it, yes, 650W is plenty. The card has a theoretical maximum draw of 225W (but only pulls about 170W max).

I am using 400W power supply with this card and it works just fine. This card has pretty low power requirement especially since it has no cooling fans. This card is designed to be fully fanless by using bigger heat sinks. I mainly used it for the good performance, smaller profile and fanless design. Please let me know if you have further questions.

It may run on a 425W PSU but it will run sluggish. Yes the card requires you have two 6-pin connectors hooked to it to run properly. It will run properly if you upgrade the power supply. The card requires a minimum of 500 Watts, but my suggestion would be to go to a 550w at least or a 600w PSU.

I paired this card with a 400 watt power supply, and that's about as low as power supplies go. So I'd say you're safe with at least 400 watts.

this should help, just enter in everything on your rig and It will give you a decent estimate of power needed to run it. I suspect you should be fine with the 450. http://extreme.outervision.com/psucalculatorlite.jsp

Will it support it; Yes. Also under full PC load you will be around 500-550w (the cards alone pull 400w together). This will put you right in the efficiency "sweet spot" (92% at 120v). Looking at the graph you can see efficiency starts to decline over 50% psu load. Your idle load will drop below the efficiency "sweet spot" but only by 2%.

The card itself is rated by Nvidia to use about 155 watts. If your just running one you won't need to buy a real heavy power supply. the computer I built with this card calculated to use just under 400 watts overall (and I put a 4th gen i5, 8 gigs of ram, 2 hard drives, multiple fans, 2 DVD/blu ray roms, and a decent mobo) and I used a 500 watt psu. Just make sure your power supply has the proper connectors ( you will need an 8 pin and a 6 pin connector to power this card, careful not to confuse your 8 pin motherboard connector with your 8 pin video card connector.)

It's should work fine the card does not need extra power. All it need is the power from you PCI Express and you good to go.

500w is recommended yes, but this cards typical power usage will be around 150w at peak, graphics cards generally don't use all the 500w. To be safe i would highly recommend a 600w psu, just so you can have some head room so you don't bottleneck the power supply.
