So i just ordered a gtx 770. I just noticed that the minimum power reccomendation is 600w. That's exactly what I have: a 600w Thermaltake PSU. Am I ok with the minimum? Maybe this comes from watching too many Home Improvement episodes, but, is this enought power? Or do you think I need more power <insert grunt here>?

Thanks guys (or gals{probably guys})!

Hmm Honestly if that's the Minimum required then yes, it's the "Minimum" for a reason. Just like the "Minimum" system requirements for a PC game.. although totally different the concept is sort of the same..

Anyway, I would upgrade your PSU ASAP though, maybe 650-750 Watts should be gravy. ( I would prefer a 750 myself)

Edit: Just make sure you don't draw too much power from things in your PC. For example don't have 4 DVD drives and 4 HDD's and a bunch of USB attatchments and you should be ok. In other words, don't overdo it with the power consumption. ;)

All I have are 2 HDDs and 1 DVD drive. Other than that, it's just the occasional iPod connection for syncing.

Then you should be fine. =)

Just... Please, do me a favour and buy yourself a new PSU so you have at least something in reserve. Please? I have actually ran into severe issues due to my PSU being underpowered, even tho it should not have been. Thing is, I doubt you have actually spent all that much money on your PSU (so take those 600W more as 'Oh sure, it'll be 600W, when weather is good and I have enough followers on twitter), and it'll only get less efficient as time goes by.

Fenixp is correct, and also as I stated. Atleast get a 750W PSU and you should be okay. If you want a PSU that you can most likely use later on get a 1000W or above. Either way works.

Its been 3 years since I built my PC, so things may have changed, but power supplies are tricky. You cant go by just wattage. Each power supply will have a bunch of stuff listed on it besides to total wattage, and that stuff is important. On top of that, quality is really important in a PSU. You can have a 600w power supply that's going to do a much better job than a 1000w power supply. If your power supply goes, it can take other PC components with it. If your power supply seems to be working, but isn't quite delivering enough power, it can also damage other components. When I was taught to build my own computers I was told there are two components you cant cheap out on. One was the motherboard, the other was the Power supply. I have ignored this lesson several times. In my experience cheap motherboards don't last, and cheap power supplys fry good motherboards.

When I began looking into building computers I was told you work out the overall power drain for your system then add a minimum of 20% to give headroom for any additional USB HD's or power drains for high end gaming.

Also when you go looking for a new PSU in time, I would suggest looking for one which has a 'Gold' or 'Silver' rating as these tend to have more efficiency in their power consumption to output.

EDIT::: Sorry, I am not trying to tell you what to buy. I am actually looking to upgrade to this when I have some spare money. We all live and learn. You just have to hope you have the best of both for the price you can afford.

Damn! Sounds like I should up the power to be on the safe side, huh?

You are good with 600W
after all 770gtx are just reheated potatoes (a overclocked 680GTX)

good luck ;) i would go for 8k series from radeon though.

Now I make those things a priority. I don't have much income, so I do have to cut corners. I just cut them elsewhere. I don't get the best memory, I just keep reusing my boring old case, I stick with on-board sound. My biggest cost saver in my current PC was probably volume though. I got what at the time was a decently powerful video card for unusually cheap because its fan was really loud, and the price was dropped because people didn't want the noise. It wasn't as big a savings, but I did the same thing with the CPU cooler. So I had a really good gaming computer that just happened to be really loud. After 3 years though, it can no longer max out new games :(

I don't know what your system config is or what PSU you are using but your system power depends from a couple variables.
There are a couple PSU simulator that can help you choosing a right one (just search for it).
Generally from those 600W the PSU most likely only delivers around 80% (depending of the model you have), so yes you, probably should have a higher wattage quality PSU.

Anyway, you can try it with your current PSU, if you the notice that your system crashes or is unstable you'll know that is probably lack of power.

Oh, and if you know Scotty you can always ask him to tweak your PSU for more power. :)(shameless star trek joke but couldn't resist :P)

FYI: The PSU I currently have is a Thermaltake 600w.

Yes, but do you know what model? Termaltake has a couple of 600W PSU and not all are the same. Some are better than others.
Anyway you can check this PSU calculator and see what power it recommends.
