PSU recommendations for Apex DM-317-A?

[Skygee]

I have settled on buying the Apex case for my router build, but do not like the reviews for its included PSU, so I would need to replace it. Anyone know of a PSU that fits? It must be around 400watt, and have mostly good buyer reviews.

The case uses standard size "TFX" power supplies.

Thanks for your help. I have looked over both PSUs, and the mixed reviews suggest neither are any better than the PSU included in the case. Its just too big a gamble, so I must change to a case having a PSU easier to replace. I decided to try for the HEC Compucase 7K09BBA30FNRX. I'm hoping either Seasonic SS-300TFX or SS-300TGW will fit it. If you are not too ticked at me for making this U-turn, maybe you can tell me for sure whether on not either PSU work in the HEC?
