Three 1000 W 80 PLUS Gold-Certified Power Supplies Tested
We received a trio of 1000 W power supplies priced between $200 and $300, so we ran them through our usual suite of tests to see if they really live up to their 80 PLUS Gold certifications. Surprisingly, all three hiccuped during efficiency testing.
Rosewill Lightning-1000
Rosewill is celebrating its debut in our PSU roundups with the Lighting-1000. The Lighting-1000 is an 80 PLUS Gold-certified PSU with a 1000 W power rating, and its looks stand out from the competition. First, the modular cables are screwed in, instead of plugged in. This should counter some of the criticism that modular designs receive, given the fact that they add one additional failure point should a cable come loose. Second, it has LED lights. The user can choose between blue or red. Or, switch the lights off completely. The build quality is good, even if it does not feel quite as solid as the OCZ PSU. The sliding switch for the LED lights feels a bit cheap, too.
Rosewill only grants a three-year warranty, but in return the PSU costs a little less than OCZ's at $220, too. There is nothing to criticize in the way of cable count or their length. The modular cable parts come in a large case, fixed with rubber bands. The single 12 V rail is rated at a maximum of 83 A, just like the OCZ Z1000M.
