Final Thoughts

When be quiet! reached out to ask me to check out the Straight Power 11 Platinum supply, I was interested to see what be quiet! can do to differentiate itself from the pack. I feel that aesthetically be quiet! made some great choices, especially with the grille that you will likely never see. The labeling, I think, was a bit of a slip, but if it's under a PSU shroud, it may be of no consequence.

What we like

The Straight Power 11 Platinum series is merely beautiful. The quality of build and materials is excellent, and among the best, I have seen to date. The grille alone is something that is simply put, beautiful, and while, for most, it will be hidden forever, it creates a special feeling when you first open it up and see it. The ability to barely break into the 50's under an insane load is awe-inspiring and speaks to the engineering that be quiet! has done with this unit. The silence of the cooling is impressive, and I stand by the fact that I believe it is one of the quietest I have had the chance to test thus far. The side by side PCIe cabling is great and allows direct cabling form PSU to GPU with no pigtails to muck things up. The all-black wiring is also lovely but expected at this price point.

What do we think could be better?

The things I don't like will partially be my personal feelings, along with a comparative analysis of what I have seen on the market. First up is the lack of a way to store excess cabling. I know this may seem like a severe knit pick; at the price point, I do think users expect a certain level of presentation, like something like Apple, which is widely considered the gold standard of packaging designs. The application of the label on the side, which would be visible through the main window panel if there is no shroud, I feel is a weird choice, especially when you consider the opposing side has the embossed be quiet! name, which would look far better.

I cannot say 100% without cutting out the back panel, but I do wonder if cooling would be better if the area around the mains toggle and AC input receptacle were opened up with metal mesh-like the rest of the rear to allow better exhaust flow. One more point and probably one of the worst for be quiet! and this supply is its warranty, five-years is half what most other supplies at this level offer, and that will likely be a stumbling block for some.

For the price be quiet! demands, I do think be quiet! still has a competent unit. I do believe some of the small quality of life improvements would make for a better overall reception by users, but the unit delivers what it should and is as good as others if not better in its price category. The Straight Power 11 Platinum 1200W gets a solid recommendation from me, as it delivers a reliable experience with good thermals and little to no noise. Just be mindful of the shorter warranty, should something ever happen. This is why it fell just short of achieving an editor's choice or gold.
