Choosing a 1000 wat psu

post #1 of 16
Thread Starter 
Hey guys first time poster here, I'm having trouble choosing a 1000 wat psu for my new rig.
Here:
http://pcpartpicker.com/p/3nA6o

Im having a hard time choosing between the Corsair rm 1000 or the Cooler Master v1000, as Ive read a couple of places that Nvidia recommends atleast 800 watts for 780 sli.


Now in my country (Denmark) the price difference is 150 kr which is about 30 dollars.
The cosair unit goes for 228,11 American dollars, while the Cooler master goes for 257,33 American dollars.

Which one do you guys recommend? smile.gif

I've heard the RM class uses cheap components. See below:

so I'd go with the CM V1000. It seems to get good reviews.

1000W is pretty overkill, you would be fine with an 850W, even with overclocking.

If you are dead set on 1000W then the Cooler Master V1000 is a much better option than the Corsair RM. Some other good value options:

Yeah I lurked through that thread a bit, though none of them mentioned the 1000 wat, or I somehow missed it

You can just do the math. 780's pull about 250W maximum at stock. The 4770K pulls about 85W maximum at stock. Add 100W for other components and that totals 685W.

Factor in overclocking and 850W will still be enough.

The PCPartPicker page also gives you an estimation, for your build it's 682W which stacks up with my rough calculation.

The Seasonic Platinum 1000W is pretty bad value for money, it's not even the best 1000W you can buy. The Antec HCP-1000 and Super Flower Leadex Platinum 1000W are both better.

Cooler Master v1000 is considerably better then the RM which is made using sub-par internals. That rig much more then a 800-900w unit is overkill, if budget is in mind, you certainly don't need the 1000w.

The Corsair RM series is currently getting a "hotfix" and they are rolling it out now, but it will probably take retailers a couple months to actually start selling the new stock.
I highly recommend the Seasonic X-850 seeing as you dont need a 1000W PSU unless you decide to go custom loop and volt-moding the GPU's. The Coolermaster V850 is also a fantastic choice. Also, I believe the Rosewill Tachyon 850W is currently on sale for cheaper then the other PSU's mentioned.
