Even though 1200 Watts is ludicrously excessive for the typical modern PC, such PSUs are necessary for very advanced or application-specific systems, such as quad-SLI gaming computers and cryptocurrency mining rigs. The market for such equipment is small and very demanding, but succeeding at the top can also affect the reputation of the manufacturer, increasing the sales of their mainstream equipment. This desire to have the best halo product results in strong competition between manufacturers, and it also moves the industry forward as the new technologies developed at the top eventually make their way into mainstream offerings. We had a look at FSP's and Seasonic's offerings, the Aurum PT 1200W and the Seasonic's SS-1200XP3 respectively, a few weeks ago. Today we are reviewing Cooler Master's contender for the 1200W PSU market, the V1200 Platinum.

The main difference between FSP/Seasonic and Cooler Master is that the former are ODMs (Original Design Manufacturers) -- they design, manufacture, and sell their own products. Cooler Master on the other hand has no such capability; their products are generally based on someone else's design (with tweaks and component choices made by Cooler Master), and this ODM also undertakes their manufacturing. This includes the V1200 Platinum, which the company hopes will compete in the top segments of the PSU market.

As its name suggests, the V1200 Platinum is an 80 Plus Platinum certified power supply capable of 1200W of continuous output. However, any advanced user knows that these figures alone mean little regarding the actual quality and performance of a PSU. We are going to closely examine the efficiency, power quality, and thermal performance of the Cooler Master V1200 Platinum in this review and, more importantly, see where it stands in relation to the competition.

Power specifications ( Rated @ 50 °C )
AC INPUT 100 - 240 VAC, 50 - 60 Hz
RAIL +3.3V +5V +12V +5Vsb -12V
MAX OUTPUT 25A 25A 100A 3A 0.5A
125W 1200W 15W 6W

Packaging and Bundle

The packaging of the V1200 Platinum is simple and effective, with a serious, professional artwork theme. The front of the box notes only the most important features of the unit, but more information can be found on the sides and rear of the box. On the back of the box Cooler Master claims that this unit can save you over $450 compared to an 80 Plus Bronze equivalent -- if you have a 1000W system at maximum load powered on 24/7 for five years, that is.

The bundle of the V1200 Platinum is very minimalistic for a top tier product. Cooler Master only supplies the fan profile switch bracket, a few cable ties, and four black screws. There are no cable straps, thumbscrews, or even stickers to be found. Not that this generally matters, as most users looking at buying a top tier PSU typically have plenty of extra thumbscrews around, but it is a bit barebones.

The modular cables are supplied in two separate nylon bags. All of the cables and wires are black and, with the exception of the sleeved ATX cable, all made using ribbon-like "flat" wires. The cables are packed using wire ties, meaning that there are no cable straps to be found here either.

    If i remember correctly, at the same frequency every +3dB sound seems 2x as loud and every +10dB sound seems 10x as loud. as different humans are more/less sensitive to different frequencies even at the same dB.
  • jmke - Tuesday, November 25, 2014 - link

    that counts indeed for dB. But notice that the sound levels are measured in dBA. A weighed it takes +10dBA to have make it seem twice as loud, not +3dBA ;-)

    How does the 24pin ATX cable connect to the PSU? I'm assuming the 2 ports labeled 18P M/B and 10P M/B are involved; but since they have a total of 4 more pins than needed I'm curious what's going on since it's apparently more than just splitting the connector to make it easier to arrange everything on their backplate.
  • vred - Friday, November 21, 2014 - link

    You are right about the connectors. This is not a one-to-one connection between the two sides of the cable.

    Exactly how many people out there are running 4-way SLI? They seem to be horribly over-represented in tech news.

    Because we are awesome?

    Both of you?

    No, we're speaking of ourselves in plural. Do you mean there's... *another* one?

    The conclusion says: "it could be a good choice for systems that require a lot of power and operate under harsh conditions, as well as for gamers and professionals that do not prioritize low-noise operation over reliability and power quality".

    Isn't that completely wrong? For any gamer with a <800W system, the PSU will be be completely silent. Since that power limit covers almost all real-world gamers, it seems to me that it's the ideal (if expensive) PUS for "gamers ... that do prioritize low-noise operation, as well as desiring reliability and power quality".
