Yes, 600w is enough to meet your needs.

Yes, 600w is enough to meet your needs.

Are you sure? I wanna make sure because once this build is done. Im not gonna have enough money for another power supply

The GTX 970 only requires a 500w PSU. You are fine with the 600w PSU. If you want more head space, then get a larger PSU now (just for peace of mind...but it is not necessary).

What is your PSU budget?

More specifically, a 970 requires 28 amps total system power. Amperage is the spec to use. Wattage is listed conservatively to account for low amp PSUs.

Most 600w PSUs have 35 amps or more, with a few having 30 amps. I've only ever seen one with less than 28 amps, an Apevia Dark Side at 25 amps.

Is that a yes or no?

So is that a yes or no that its enough watts

It's more than a yes or no, it's a tutorial. You should have been paying attention the the part where AMPERAGE is the important spec, not wattage. Responsible manufacturers like EVGA and MSI list not just wattage, but amperage as well. When manufacturers only list wattage, it's just a vague, conservative estimate to allow for PSUs with low amperage.

So for all intents and purposes, your 600 watt PSU likely has enough amperage like I said. It's best to know the exact amperage and how long it's been used, as the capacitors can age and overall output can degrade over time. You never provided the brand and model of the PSU though, so I can't really say for sure.

Note as well that just because a given PSU may be rated at just enough amperage, does not necessarily mean it can sustain it at peak loads for long durations. This is typical with cheap PSUs, and why most avid gamers recommend quality ones.

Your PSU brand and model number will be listed on the sticker on the side of it. If it has more than 1 +12v output, you may be able to find it on this chart, which shows total amperage for a lot of PSUs. http://forums.guru3d.com/showthread.php?t=205763

The reason the chart is useful is you cannot typically determine combined 12v rail amperage by adding the sum of the rails. It's usually a lesser number, as some amperage is lost in combining them.
