Kingwin Lazer Platinum Vs. Seasonic M12II

post #1 of 7
Thread Starter 
I'm trying to get a good quality PSU for my next rig, and to hopefully tide me over for a few more rigs to come.

Right now i'm looking at these, but i'm open to suggestions:


Specs for the Rig:
i52500k (OCed 4.5-4.9 ghz, hopefully!)
Asus P8P67Pro
8GB DDR3 1600
1 6870 [If I switched Mobos and crossfired two 6870s, would the Lazer be able to handle it? ]
2 7200 RPM HD
1 SSD
1 Sound Blaster PCI card
1 Wireless Card



according to this handy dandy calculator I need a PSU ~521 watts.
What do you guys think?

The Lazer should be able to handle that load but I would suggest a bigger PSU just for future's sake. Might I suggest the http://www.newegg.com/Product/Product.aspx?Item=N82E16817703022 PC Power and Cooling 910w. It's an extremely solid product at a good price IMO biggrin.gif.

Yes, the Lazer Platinum 550W will handle the setup with ease(the CFX one that is).. it's in a whole different class than the M12II and it's also better than the X650.. essentially it's the best power supply on the market at that output level, bar none.

Best value: Antec Earthwatts Green 650W - $52.46
http://us.ncix.com/products/?sku=59339

Great quality: Seasonic X650 - $100, posted earlier

Best quality: Kingwin Lazer Platinum - $162, posted earlier


Don't consider the M12II, even though it's very good, since the superior X650 is cheaper. I'd get either the Earthwatts or the X650 depending on the budget, unless you really need the top dog stuff for everything in your rig. I'd consider the Earthwatts Green to be "good quality" but not great, definitely worth more than what it's selling for there. If you really end up with Crossfire, you'd be short on PCIe power connectors and would need to use adapters though.

Thanks for the help all.

I think i'll get the x650 for $100 and call it a day. The Lazer Platinum is super tempting, but the price is a bit of a downer.

What am I really losing by going with the x650 over the Lazer?

X650 is fanless up until 20% load(130W)
Lazer Platinum is fanless up until 500/550W load at which point the fan will start spinning, it will also offer gold efficiency up to 650/700W load.. in terms of regulation and ripple suppression the differences are small but the Lazer Platinum is still better.

Okay my heart says the Lazer but my wallet says the x-600, so I went with the x-650. Because i'm cheap : )

Thanks for all the advice!
