It depends on what your system power draw is. Would need to know the rest of the components. The XFX 7770 draws about 80 watts under full load which is why it requires a 6 pin PCI-E power cable.

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

you will be perfectly fine i have a 430 watt psu currently and i never even get near t going over that. this graphics card uses only about 80 watts on average. The only time you need to worry about wattage is when you get higher end cards or more of them.

You need to upgrade to 500. My PSU was only 300 W and I upgraded to a 500 W Corsair unit. The PSUs aren't that expensive. I didn't want to take the chance. Haven't had any problems.

I use a 450 with mine and it seems to be working fine. I didn't get a message about any psu requirements though.

I would get at least a 450 W PSU... preferably 600 W. I was running into issues with a 450 W, but upgrading to 650 solved all my issues.

I am using the antec 550 watt power supply which is working well for me with the am2 processor 2.6 ghz. I had another system with a 350 watt that seemed to run a little noisy. I don't know the minimum requirement but if have had enough power supply failures to know not to the minimum out. Sometimes the power supply manufacturer fudges the numbers. At least that was true in the past. Since this is for my company I opt on the safe side.

Not a good power supply. My rig was using only 300watts and the supply would crash. Try to find a good gold certified one, you wont regret the extra safety

A 500 watt system is the lowest recommended .I have an 800 watt power supply, because I'm running a lot of extras. It does require a 12v PCIE supplementary power connector as well.

I just purchased this card and it requires a minimum 300 Watt PS with a minimum of 20A on the 12 volt rail. This is based on a newer core-i7 processor. I have an older core-i7 and my card seems to be working ok with 18A on my 12 v rail. I am only running One monitor at the moment, but I will have to watch during heavy gaming if my PC crashed or reboots. If It does than I will need to update my Power supply.

The item is shipped without a power supply or any info regarding power supply requirements. I would have returned the one I bought, but, due to circumstances, I did not try to install the unit before the return period had expired. Sorry I can't be of more help, but I am stuck too.

Hmmm... When I upgraded the PSU, I believe it was around 250 watts or a bit less than that. For sure, it wasn't over 250 watts.

You will have to upgrade you PSU to at least 400w for to run some games, I would recommend a 600w or above. I have a corsair tx650 and it runs cool even with a lot of power demand.

there are numerous PSU calculators on the internet where you can input the hardware you have. however, 400 watt is a little on the small side. Also, see the manufacturers recommended specs.

550W is not enough for this card and all the other components in your PC. Technically your PC will run, but the power supply will be maxed out quickly when playing a graphically-intensive game and you won't get full power out of your hardware and so your performance will suffer (remember, you only get 80-90 percent of the power from a high end PSU, so you are only actually getting 450 or so watts from this PSU). You should get a 700-750W minimum to ensure you are not wasting money on the graphics card. Also, don't buy the PSU used - as another person noted it won't have a warranty and you presumably won't know how many hours have been put on the PSU and so it's life could be considerably shortened. 550W is not enough for this card and all the other components in your PC.

If you go to pcpartpicker.com and type in all your hardware it will tell you a recommended watt. Also I bought mine used and is in great shape. I trusted amazon enough to buy used.

400 would be pushing it. I have a 600w and it does fine. I would say the minimum would be 500w but it really depends on your total power consumption system wide.

Fine then buy a 350W when it doesn't work you know what to buy. I've been building my own systems for 15 years and building with a higher power PSU is the surest way to reduce heat in your systems and reduce problems. Do whatever you want, but 350W is too small.

It's a 55W TDP card. That means it'll consume up to 55W when under full load. I've seen many guys reporting being able to run this card with their stock 280-300W PSUs.

Provided there is an open pci slot on the pc (which you can find out by opening it up) and the psu is putting out 400 - 500 watts you should be fine. Upgrading stock PC's can be tricky though, I wouldn't recommend it personally, hard to get it to the standard you want.

Hello, this APU uses 100W of power, and you should use it with at least a 300W power supply. It's always a good idea to go with more power if you can afford it though. Personally, I am using a 480W PSU and it works great.
