Is the 600W PSU enough?

[dirtybliss]

So I decided to get the Radeon HD 7970. However, today when I was picking up my monitor, I asked whether they had the 7970 and the guy said no. Then I asked if he had the Corsair CX 600 Modular and he said that he did but it would not be enough for the 7970. He said that I needed at least 750W which I highly doubt. I just wanted to make sure on here. Thanks!

Well if your only running a single 7970 a Corsair Brand PSU would suffice, but you could not upgrade any more components and you SHOULD NOT overclock your 7970 as that will raise power consumption very high. I found this out the hard way with a GTX 580 and an older Kingwin 650w PSU, i ended up BLOWING the PSU out because i was OCing the GTX580

So I should just play safe and get a higher power supply?

Here is Guru3D's power supply recommendation:

Radeon HD 7970 - On your average system the card requires you to have a 550 Watt power supply unit.
Radeon HD 7970 Crossfire - On your average system the cards require you to have a 750 Watt power supply unit as minimum.

If you are going to overclock GPU or processor, then we do recommend you purchase something with some more stamina. http://www.guru3d.com/articles_pages/amd_radeon_hd_7970_review,8.html

If your planning to OC that card i suggest a 700W or higher would be much better and safer but if your planning to just use the card without OC'ing a CX600w Corsair is enough to power your gpu and pc. 7970 alone is a beast and doesnt really need to be OC'ed for most of the newer games.

Hmm. So would 650W be enough? It says that 550W should be the minimum on Gigabytes website. I'm using the Gigabyte Radeon HD7970 OC 3GB card if that matters, by the way.

650 is enough just get good quality brand like corsair / seasonic

 

[dirtybliss]

Ahh, alright. I'm getting the Corsair TX-650 so it should be all good. Thanks guys!

Bear in mind if you plan on going Crossfire down the road then you'll need a new PSU as well, whereas a 750W PSU will be a little bit more than a 650W PSU right now, and give you that headroom for later.

Ahh, thanks for the heads up.
