No the sparkle unit is a VERY nice unit. I bought it over all the PSUs listed here. Its not made by FPS group its my by sparkle corporation, the guys who make the graphics cards. It uses an OEM known as GreatWall, which makes very good top of the line units. JonnyGuru tested it, it tied the AX series on ripple and other things. He said the only problem was some capacitor whine that they said would be fixed in the final retail version, as well as the fan didn't keep spinning after unit was shut down, which was advertised.
The unit not only comes with a 80 plus gold certificate, it also has all its electrical characteristics outlined as well. They really made one hell of a PSU.
I bough tit, my system in my sig can pull 980 watts from teh socket, and it did, and my PSU stayed steady. I took it over the AX. http://www.jonnyguru.com/modules.php...Story&reid=212
"This unit was stable, incredibly powerful, and those scope shots were absolutely breathtaking. But, on the other hand, we have that squealing at high loads, even if it's not that loud when mounted in a computer case. Half a point comes off for the squeal, and I'm calling it done. 9.5."
"ight now, this unit can be picked up at Newegg for $259.99. That's twenty bucks shy of an AX1200. Now, if performance were the only factor to go on, that would be a heck of a deal right there. But, the squealing and missing fan control issues are going to hurt the Sparkle a wee bit here, too. Not too much, though... we did find a gift card in the box. 9."
I haven't heard any squealing. Its fan never runs at high, but it does state it has a feature that the fan keeps spinning after shut down, maybe the PSU needs to be hot which is never really gets unless I am benching at 5ghz and my GTX 570s at 300 watts a pop with OCp disabled.Edited by Sin0822 - 2/17/11 at 1:55pm
