UpBrightNew Global 4-Pin DIN 24V AC/DC Adapter for YAMAKASI Leonidas 300 Sparta Multi 30" LCD Monitor 24VDC 180W Power Supply Cord Cable PS Charger Mains PSU

I have a Yamakasi Sparta 301 that worked well for about 2 years and suddently my computer couldn't "see" the monitor and so would not send video to it.Neither an NVIDIA GEFORCE or an AMD Radeon card could "see" the Yamakasi. I tried another "stock" Yamakasi power supply and the display would turn on for ~5 seconds then go black. So now I tried this BEEFIER power supply and the Yamakasi now works as it should. The display is "seen" by whatever video card I connect it to.Since the Yamakasi only worked for 5 seconds at a time with a brand-new "stock" power supply, I am going to guess that over time something inside the Yamakasi display has increased the amount of current it draws from the power supply - some regulator or digital board- and the current demand now exceeds what the stock power brick could handle, whereas this new BIGGER supply (9 amps vs 7 amps for the stock supply) is capable of powering the display.There are a number of folks out there who have had Yamakasi 30-inch "display-no-longer-seen-by-computer" problems, and I'll bet you dollars to donuts that this supply is the answer.

Seems to work well with the sparta 301 as I haven't had any problems with it getting hot and turning off the monitor (like the power brick that came with the monitor did). The power brick is bigger than expected but much better made than the one that came with the monitor. I think the price is way too high but it really is the only option for the sparta 301 that I could find being it needed 7amps.

This AC adapter is better than the one that came with the unit when I ordered it. No adapter and higher wattage all good

I thought my beautiful 30" Yamakasi (Sparta) was going to gather dust for the rest of its life, but I found this on Amazon and it worked perfectly. Back in business.
