Also, it would have no problem powering 2 mid-range GPUs. For 2 GPUs, 150W of the total comes from the PCIe slot (75W per slot) itself, which is a large chunk of the burden this drive bay PSU doesn't have to deal with. It'd do just fine.
JPM, I agree no PSU should ever be used above 75% capacity. This is also stated in the review. The 450w PSU failed not only the TORTURE test but the entire review. Is it a fair test? Yes, all PSU's are tested the same way. Is it a realistic test? Maybe, maybe not. For the average user, NO. For crunchers pushing their equipment hard 24/7. I think so. Especially for people like me who OC. They really didn't have anything good to say about it no matter what load was placed on it.


"The Bottom Line

The ePower Juice Box 450W power supply is an interesting niche product that was so heavily flawed that it doesn't even fit its niche. Not only was the unit incapable of running at its full rated output at realistic operating temperatures, it was poorly constructed with components that are not exactly known for long term heat tolerance and shoved into a situation where there is little ventilation and poor efficiency. All in all, had the unit not failed, not had poor DC Output Quality, and not been ridiculously loud it would have had a questionable longevity that was also not backed by any obvious warranty support. If ePower was going for the trifecta of sketchy they nailed it today with the Juice Box 450W. When we started the review for this unit was showing as being available for $20 from Newegg, and the Visiontek version was available for $70 on Amazon. (What really amazes us is how Visiontek could be suggesting any of its customers plug this into a high dollar video card. Ouch.) As it is today, the ePower unit seems to be out of stock most everywhere we look, and that my friends is damn good blessing in disguise. So all in all these guys knew what a big hunk of crap it was and nailed it before we did. Good riddance."



This PSU got a very high rating fom the same people.

Is it comparing apples to oranges? Yes, if price is included. No, If you consider its just 2 PSU's being given the same test.

The only reason I picked this review is because I own one. Apples to Apples for me. Two PSU's I own.

I only posted this so anybody considering buying one will know what they're getting.
