Overclockers Club tested this PSU out on their systems
http://www.overclockersclub.com/reviews/ultra_x2_750_ee/6.htmhttp://www.overclockersclub.com/reviews/ultra_x2_750_ee/7.htmIt passed with flying colors, charts included on the first link
Virtual Hideout also tested this PSU out
http://www.virtual-hideout.net/reviews/Ultra_X2_750W_Extreme/index2.shtmlThey couldn't even dent the power output of the PSU.. with their rig they could only get it pushing 350W and it didn't even break a sweat.. they even stated it had a long way to go to max it out. Then again their test system specs weren't all that great.
Test Rig:
Abit IP35 Pro Motherboard
Intel Core 2 Duo E6850 (3.0GHz)
Crucial 2x1GB Ballistix Tracer PC2-8500 Memory
ASUS EAX1950PRO Graphics card
WD 80GB SATA II HDD
Samsung Super WriteMaster SATA DVD+R DL
They too posted a link to the Enthusiast web site on their testing about testing over 500 watts... so it remains to be seen..
Now I'm not saying that Ultra's PSU's are the best.. but from all the reviews I have read.. it should handle quite well.. and if it doesn't meet specifications, I have a lifetime warranty on it.. I will just ship it back in to them and get it replaced.. by their warranty agreement, if the PSU fails to meet specifications 2 times when I send it in, then they will replace it with the next one up.. same warranty applies...
so it is a good bang for the buck.. I have seen more positive reviews on the PSU than negative ones.. some reviews say it won't go over 510 Watts, others it worked perfectly.. but with all PC hardware you never know until you power the thing up..
If I have too many problems with it, I'll send it back to Tiger Direct or Ultra and get a better one without paying any more than what I already have.
The biggest problem with the Enthusiast's site testing is that they only had 196 Watts input power.. you have to have an 82% ratio on a PSU
196W total watts into a 750W PSU is not a proper test. Sure it may run a regular Joe's system but you need to "stress test" it to make sure it functions near its stated specs.
Enthusiast web site failed to test the PSU properly.
I am going to contact Ultra and find out if it is a recall item.. there may be issues between them and NVidia
