I got this card about a week ago. I'm running it with a i7 920@ 3.2 GHz, 12 GB ram and a 550 W PSU. Based on specs I thought this card should use less power than the card I replaced, an HD 5870, however I had a strange thing happen while playing...

I'm not an expert on PC power requirements, but after 15 years of building and repairing PCs, I can say with certainty that the power supply can be the most finicky part of the computer. I'm not saying that it is what is causing your issues, but I've seen similar problems with power supplies in the past. It can also just be your power supply dying and it's only a coincidence that the symptoms decided to manifest after you switched to a new video card. My advice is to try to troubleshoot it as best you can. Perhaps underclock the new card to see if the problem disappears. Or if possible put back in your old card to see if the problem remains the same. If it does, it will definitely let you know something else is going on.

Mine runs a Radeon 7970 6gb and this card on a 650w gold certified psu without issue. Can't speak to running it solo, though.

I have this coupled with a 6 core CPU at 3.5GHZ and I have not been able to find a single game that I cannot play on high or more settings. As far as the list you provided, short of your other component limitations I don't see why you wouldn't be able to crank these up to max with this card. Also it stays very cool ( I have a roomy case) and it is nice and quiet. Great card.

I have this card on a 280w- core i5 machine - without any problems for about an year! Worth to mention: I use a pair of ssd's instead of hdd - there is significantly less power drainage from hard disks....

No your perfectly fine since this card is a low power consumption card. Now it depends on what kind of processor you have. If you have intel you may need to upgrade it. If you have an amd like a 4100 your perfectly fine. If you have that processor and gpu it only requires 240 watts

I have no lag on mine. If it isn't ultra then its right below it. Basically I haven't had any lag on anything I've played so far. Its a great card and runs cool.

Hi, Ryan. I can't speak to your specific hardware configuration, but I can give you mine for a somewhat-apples-to-somewhat-apples comparison.I am running this same GTX 650 Ti 2GB in a machine with: i7 950 overclocked to 3.07GHz, 16GB RAM, 1x 64GB SSD, 2x 1TB 7200RPM HDD, 1x 750GB 7200RPM HDD. This machine has a 600W OCZ PSU, and I've had no issues with lack of power. YMMV, of course.This is a great little consumer-level card, probably the best I've owned so far. It has taken everything I've thrown at it (all games on "high" settings) with ease.

32 watts running 3d. My pc has a stock power supply in it so it's probably somewhere between 200 and 300 watts. This card works great with it. Cheap too. I've run portal 2 on it just fine. Old games that i can vouch for on this system are Star Wars Republic Commando and Red Faction. Also the first Witcher. I haven't tried newer games than portal 2. I've been extremely happy with it.

I am actually using a 300w PSU and everything works just fine for the past week (i7-4770, 8G ram, two HDs). But don't try to take my word and keep a 300w psu for long bc it's supposed to be dangerous to your equipment. I've ordered a 500W PSU and will replace as soon as it arrives.

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.

Nice card! It consumes about 180-185 W. Depending on what you're running it in and how much stuff you've got in you're box, you may want to bump it up a notch. You can check the AMD site (or call them) if you have doubts. The site should have recommended PS ratings.

The card runs planetside 2 on high with very few issues... ONly when the zone gets really full do I see any stuttering or frame slowing, and I think that's server lag and not the card. It runs Second Life on High, FarCry 3 on Ultra... The only issue I've found so far as an issue with leaving tiny squares of ghost data, and an update to the video drivers fixed that problem. I've been very happy with the card for gaming.

You have to look at the recommended specs for the game. This card is an HD7770.

I guess that would depend on the processor you used, the graphics card you used, the harddrive you used and the memory and how much you had. I've never measured the power, so sorry, I can't help.

This card is great. It's one of the few newer video cards that don't require much power. I have a 550w power supply and it works just fine.

I have 2 of these and they work wonders. Depends what you're doing/playing. If you're monitor is 120/144hZ or 4k (best to go with the 4gb version of this card) What are your specs going to be?

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.
