The new Leadex PSU's by Superflower arrived at OCUK only afew days ago. With my range of systems demanding the highest quality and stability in a PSU whilst remaining quiet in operation I decided to give the 1200w unit a heavy workout with some serious hardware. What caught my eye about this 1200w unit was its Platinum certification which is truly rare at this wattage. Pack going all green?? never!!! But more stable consistent power lets give em a try!!!
For the testing I chose some hungry components. Several 1200w PSU are not doing well with three or above 290X especially with high overclock on the cards and high clock on CPU also. Some simply wont even run this config at stock!!!
Knowing this I based the testing around 3 R290X in 3 way Xfire, on a Gigabyte OC which is incredibly fast and efficient in multi GPU upto three way and a 4770K Haswell CPU. First I ran all at stock Heaven Bench HWbot edition which draws a lot of power and has many PSU crumbling. No problem!!!. I then clocked the cards to 1185+ Core 1550+ Memory with 1.4V per card core volts. Again the Leadex is providing all the power these cards need. The bench completes with the system stable.
Time to crack open the dewar and pour some LN2. My best CPU's for benching at home with the Galaxy OC comp looming but I hoped I still had enough to challenge for at least some spoils with what was on hand
. I then took the CPU to 6.2ghz with memory of 2600. CPU voltage was 1.67v and DDR 1.9. That's some serious draw. Still the Leadex is rock stable and the system completes the bench with a world record score for three cards of 8548.869. This beats the previous record by over 300pts and is only 37 or so points shy of the best ever four card run. 8548.869 being the second highest Heaven run on HWbot with any amount of cards. This score means I currently hold ten benching world records all at once the most I have ever held all at one time.
I knew that four cards on the OC would not be efficient and yield a great score due to the low bandwidth to four cards and the lack of PLX chip which you can find in the OC Force but as I had the rig out I though I would test the PSU out against 4 R290X in quad fire all at 1180 and 1550 with CPU at 6.2ghz. The system was again stable and passed the bench mark first run.
As you can tell from the above results. The Leadex 1200w PSU seriously impressed me. Infact its the strongest I have tested of all 1200w to date and will be the PSU of choice for the new spec Polaris and Supernova 8Pack systems such is its quality, stability and performance.
