Need new PSU for - 2x 7970 1200mz | 3930k 4.7 | 120hz 27" monitor & future

post #1 of 22
Thread Starter 
I was running a Thermaltake Toughpower W0133RU 1200W since 2009.

I gamed and folded a lot with it over the year....the pc is just shutting down under any stress...

so i guess it is just time to buy a PSU. But loking for the future e.g. will likely upgrade to ivybridge E socket 2011 and whatever future GPU's are the shiz...

In short run.. what are thoughts based on running my below rig ... 2x 7970 1210mz+/- | 3930k 4.7 | 120hz monitor | h100 | koolance all in one pump (lazy)

Intial thoughts are below...

PC Power & Cooling Silencer Mk III Series 1200W

SeaSonic X-1250 1250W

Lepa G the modular cables look kind of short anyone know the length? (I have a full tower)

COOLMAX ZPS-1600B (14642)

thanks thumb.gif

The seasonic x-1250 is what I would recommend. I had it in mind even before I read that you where thinking about it tongue.gif

I guess s 1200-1250 enough with the overclocks? I feel like I am cutting it close... just would rather not tax it.

If you're sticking with two 7970's and don't plan to add any more graphics cards then a good quality 1000W is perfectly adequate.

The 3930K draws about 200W-300W depending on how much voltage you put through it. Under LN2, phase change etc it can pull a ridiculous amount of power but I'm assuming you're not going to be doing that. Source -
http://www.tomshardware.com/reviews/core-i7-3930k-3820-test-benchmark,3090-2.html (They were quite kind with the voltages)

A single 7970 draws about 270W at stock but can draw up to around 400W if you really push it. Source -
http://www.hardocp.com/article/2012/01/25/asus_radeon_hd_7970_video_card_review/8#.UZyah7W1GaV (Note the values are for total system draw, subtract about 160W for the card alone)

These are your best value options -

Silverstone Strider Gold 1000W - $169.99.
http://www.newegg.com/Product/Product.aspx?Item=N82E16817256068

Rosewill Lightning 1000W - $169.99 if you don't mind the lights.
http://www.newegg.com/Product/Product.aspx?Item=N82E16817182239

Xclio Stablepower Gold 1000W - $159.99 not many people have heard of it but it's a great power supply, the OEM is Enhance Electronics.
http://www.newegg.com/Product/Product.aspx?Item=N82E16817189026

If you don't care about value and just want the best of the best then check these out -

http://www.newegg.com/Product/Product.aspx?Item=N82E16817151105

Edit: Just noticed you might be folding so you may be wanting a bit more power.

Kingwin Lazer Gold 1300W (definitely overkill but it's not too expensive) - $189.99 after MIR.

Why are you guy talking about plus 1000 watts when 850 watts could do the job just fine

You dont need more then 850 watts unless you plan on more then two video cards

his money, it's what he wants but i do agree though on one hand but dis agree on the other as having a bit more head room for PSU degradation over time compared to the 850w isn't a bad thing. sure it would take several years but hey what do I know i'm running my sig rig with a 900w and all i have is a 7770 with a 2700k ES. biggrin.gif

If you want overkill despite its a waste of money there is only one PSU i will recommend over all over others

its the brand new EVGA SuperNova G2 thats has nothing to do with the older crappy EVGA SuperNova´s
