I have an ASUS hd 7770 2gb GHz edition, and planning on upgrading to this: http://tinyurl.com/coc39bo. I have an APEVIA ATX-AQ700W-BK 700W ATX12V PSU, and I'm wondering if that psu will work with the video card I'm getting?

Well the specs of your psu meet the requirements for the card you want to put in. Whether or not the specs are actually right is another question. You are going up another 6 amps for requirements from a 7770 to a 7950 so based off pure specs you are good to go. If you start having problems though like your system freezing after installation of the new card I would have a close look at the psu though being that people have rated it at the lowest it can go. Meeting the requirements is one thing but a lot of crappier psu's tend to use substandard parts or rate things at specs that no one could meet. If you go to that eggxpert site that I linked above the tier 4 says:

"Tier 4 - Not Recommend for stressful situations. May not be able to put out full rated power above room temperature, and may slightly fail to meet ATX specs."

And they are rating APEVIA psu's in the next tier below which says they think it is even worse than that. So if it were me and I was investing in a 300-400$ graphics card I wouldn't risk a possibly bad psu. A lot of the ones can give some pretty bad variations or surges in power that could fry your computer or actually catch fire when too much load is put on them. I would stick to no more than say 50-60% max load on that power supply if you must keep it.

Agree with the others on the power supply-Do yourself and your system a favour, get something better.
More detailed specs would be useful-the 7950 is a very powerful card but it's not going to give its best without a powerful CPU to keep it fed with data and a monitor of 1080 or higher resolution.

Nice build, mate!
As long as you're using at least a 1080 monitor the HD7950 is a fine card (I have one) and the card you linked to seems to be very highly regarded so I see only one thing against the choice-that PSU.
Sorry to labour the point but you really do have a great machine there and it seems a pity to 'ruin the ship for a pennyworth of tar'. A 550-600Watt unit from Antec, Corsair, Seasonic, FSP, Pc power and Cooling, XFX or OCZ will do the job nicely.
If your budget is too tight for the HD7950+PSU, you could go for a 'Tahiti LE' based HD7870, it's only a little slower than a stock 7950 and less expensive.

It's a sound choice with masses of power, but it's not modular, you may have problems managing all the cables and keeping them clear of the internal airflow of the case (as is mentioned in the Newegg feedback) if that might be a problem this has plenty of juice and is modular:

It's main limitation is that it'll not run dual 7950s in Crossfire.
As I have already said, the Sapphire 7950 you linked to is an excellent card with plenty of positive feedback "An excellent choice if I may say so, Sir".

I ran a 7950 with a 650w antec green power and now run TWO 7950's in crossfire for about 3 months with no issues. Both are overclocked to 1050/1550 with the i7 2600k at 4.5 ghz.. You're probably fine with what you have.
