Some say its a noise factory and other say it is quite. How does this PSU compare to the supernova 750 B2 in terms of performance and quality?

I'm not familiar with the 750 B2 but I'm very impressed with the Seasonic PSU...it's quiet and has more power if I need it!

I don't have a Supernova 750 B2. However, I am very pleased with the Seasonic M12II-750. It Powers a i5-4670k (over clocked), a GTX 770 (over clocked), seven fans ranging from 200mm to 140mm, and an aftermarket CPU cooler with a huge amount of capacity to spare. I hope this helps.

I bought a 750 cause what I had didn't quite worked with this GPU, and I haven't had any problems with it. My advice is that you get a nice performing 600+ watt power supply so you don't have to worry about it. Peace :)

EVGA SuperNOVA 1000 P2 80PLUS has a rated efficiency of 92% while G2 version is rated for 80 Plus Gold which is less efficient then Platinum P2 Version. Also G2 version does not have lot of bells and whistles as P2 version such as ECO Mode if you want your PSU to be dead silent. I hope that helps. For efficiency safe and if money is not an issue, EVGA SuperNOVA 1000 P2 Power Supply is one of the best PSU on the market for 1000watts.

Yes, great effort. That NZXT is a good provider of medium quality components. Their power supplies are middle of the road, but their cooling products are up there with all the top end contenders. Cooling fans over the 77 cubic feet per minute is the new normal, but anything above and beyond is superior.

As long as your fan is clean, there really shouldn't be much noise under different load mods. I haven't heard that the fan is an issue.

I wouldn't return that just yet. Don't think this is the same model as mine, but if it's not under a load and running cold the fan is designed to adjust speed automatically and even stop. It may not be broken. That supply being 1,000 watts is going to take some heavy use before you see that fan come on I bet. My 750 stops all the time running 3 mechanical hard drives a ssd and 2 video cards.

I personally went with an 850W gold certified Corsair PSU but I am running 2 760s in SLI. I wouldn't go any less than 750W bronze because I have quite a bit of hardware inside. A 650 bronze would work just fine if it's a single DVD\Blu-Ray and hard drive type system though.

This will be my second lower supply case. I have the first generation of the bottom PSU design and I love it. The major advantage of this design is seperating the airflow from the PSU from the remaining components. It does this very well and the noise is at a minimum. The only disadvantage is that the cable lengths on the PSU must be longer to reach the motherboard and peripherals.

I'm using a 750 watt power supply, and have had no issues. My old PSU was 700 and it was fine in there too.

I was running one of these with an older PC Power & Cooling 430 W PS, never had an issue. If you are going to overclock it, you are going to have a tough time with two of them on anything less than an 850 watt power supply. But that has been my experience; your mileage may vary.

It sounds like you are building something heavy-duty. The largest one I have built used a 750 watt. I found the engineering first class and the performance solid. I would buy it again. Built like a gamer, it's still running well after two years. On a smaller machine, the tickler starting circuit failed and they sent me a new PSU, postage paid. Your UPS needs to produce a full sine wave for it, is all. That's what Thermaltake told me, anyway. Good Luck.

It its a bit large but mine had worked like a champ once I got it installed. The glow is awesome and I have had no issues running my Nvidia GTX 570. All around I love the power supply.

I disagree with everyone here AND more importantly can prove...I have a AX760i and I have the following: 2x780's in SLI, 8x 140mm fans 3hard drive and a I7 4770K OC to around 4.3... Under FULL LOAD like Aida 64 Bench, unigene, whatever---I TOP OUT at just over 500watts, and I know this because the Corsair Digital Series uses a GUI called DLink that provides a real time monitor so I can witness the fluctuation. Again TWO 780s and bunch 'o fans= less than 520watts

Single rail system.Does the PSU work as it is suppose too? Yes. It is quiet. It also comes with a 10 year warranty and I have used it. EVGA had a recall on this (select Serial Number) unit and notified the affected customers. They paid for shipping both ways and had a cross ship in place for this issue. EVGA takes care of their customers! So does Amazon. If you are curious about the cable length, I have a CM Cosmos2 and this PSU and the cables reach their points just fine. I am happy with it and will buy another for another build.

It can be noisy; you can manually set the speed via the speed control knob on the back of the unit. When set at max yes, it is VERY loud. At its lowest it does create a low hum. Temps only decreased maybe 1-3C, during heavy system load it kept my GTX 670 reference card at a nice 57-60C.

Its actually not that loud! I did not use this PSU for very long before switching to an XFX PSU which I like better and feel that it is more reliable then the raidmax.

Hi robert,Sorry for the delay, I used a watt meter to see how much my system was using. I have a big CPU cooler and this graphic card and I was reading 300 or so watts at the wall receptacle. I lean the way of others. While you could probably get by for a while with your power supply, solid voltage = stability in the computer world. If your PS is always near its limit, you may run in a lot of issues. A PS is fairly cheap and easy to install. I have a seatronic 750 S series to give me room for expansion in the future but it may be an overkill. A good 650 would be just fine for sure.Regards Hi robert,Sorry for the delay, I used a watt meter to see how much my system was using.
