I just bought a Tagan U01 from Mwave. It is really a very nice PSU supporting SLI systems.

I think the new Tagan U01 is an update version. Because the new U01 now has 2 6pin PCI-E connectors and 4 SATA, which its old version only has 1 PCI-E and 2 SATA. The 12V delivers sufficient 28A power which is well enough for my ASUS A8N-SLI system.

I called Epower tech support and they updated their website immediately! Very impressive!

There is another very nice feature which I liked a lot is the REMI Technology, a patented feature according to Epower. REMI is an EMI filter attached to the VGA power lead which lowers ripple noise and deliver clean current to high-end graphics cards...

After I install it, this PSU is really quiet. You actually won't be hearing anything even in the quiet late nite. It states 21dB ~ 27dB in the specs which applies to the real thing.

But later I found out eWiz.com sells $9 lower than Mwave.. but anyway, Tagan U01 is definitely recommended to your gaming systems!
