Cooler Master V Platinum V2 1600 PSU Review

We check out a 1600W unit from Cooler Master with 80 Plus Platinum efficiency


  1. While I don’t think its important to have a ‘pretty’ PSU, this is quite stunning visually. technical data certainly shows its going to do well.

  2. Looks like its going to be just under 200 bucks in the US. very good pricing.

  3. Very nice product, i like it, great appearance.

  4. This is great thank you, I have been waiting on a review of this for a few weeks. very nicely done. the strip idea is weird, but I suppose it wouldnt be an issue for people at home as they shouldnt be opening the PSU anyway.

  5. That is a very nice looking power supply. i love the shaped edges. Technically it seems the muts nutts too.

  6. Wanted to mention I like the thermal testing idea of 35c. I know some sites build hot boxes to 50c which is a good idea too, but it never seems very realistic to me.

  7. Very well designed and I liked the video. no offense to the bloke but it looked like something out of a war film. ‘this is a bomb, and it will blow up if I push ze button”.

  8. I like the internal structure, its a modern design which is proved to work well, especially with variable load changes.

  9. Any ideas when this might be released?

  10. Very good product, but to be fair their last range of toughpowers were pretty good too.

  11. Thats an excellent review, this seems like a killer PSU, but one question. Why did they make the red stripe like that? surely that would have been better built into the chassis itself.

  12. Very good product
