This unit is Platinum certified, uses a fully modular cabling design, and is Haswell compatible since it uses DC-DC converters for the generation of the minor rails. A double ball-bearings fan expels hot air, and there is the option to engage a semi-passive mode should you want the unit to operate silently at low loads.

Its available protections don't include OTP (Over Temperature Protection) and OCP (Over Current Protection), although the latter is meaningless in a such high capacity unit with a single +12V rail. The P2-1200 is quite large as it is 20 cm long, and its price is very good if we take into account its specifications and features. The ten year warranty is mind-blowing; we should, however, point out that it is tied to several conditions. Firstly, you have to register your product within 30 days after its purchase (EVGA informed us that this isn't necessary and they will make changes to the warranty information page, which was a little bit confusing on this matter). The warranty also can't be transferred to another owner should you decide to sell the PSU after three years has passed from the day that it was shipped from EVGA's warehouse, and owners must have a valid invoice in hand to claim it (according to EVGA for the first three years the serial number will suffice and afterwards only the original owner with a valid invoice-or a screengrab of it-can claim the warranty) . You will find all relevant information on EVGA’s terms of warranty here. A ten-year warranty looks impressive despite the conditions above, especially for a PSU.
The single +12V rail can nearly deliver 100 A, so it will feed the VGAs you can muster. The minor rails aren't as strong, but are still capable of 100 W combined, which is enough for every modern system. It would be nice if SF were to equip this platform with a stronger 5VSB rail because 2.5 A max current output is very little for a 1.2 kW monster.

Cables & Connectors, Power Distribution
The P2-1200 has the same number of PCIe connectors as its smaller 1 kW sibling, and not all PCIe connectors have 6+2 pins as a pair of these only have six. We don't understand why they were as conservative since nearly all other 1.2 kW units are equipped with nothing but 6+2 pin PCIe connectors, and some even have more than eight. Yet both EPS and all PCIe connectors are thankfully available at the same time, and the P2-1200 has two more SATA connectors than the P2-1000.
|ATX connector (600mm)||20+4 pin|
|4+4 pin EPS12V (750mm)||2|
|6+2 pin PCIe (750mm) / 6 pin PCIe (+150mm)||2 / 2|
|6+2 pin PCIe (750mm)||4|
|4 pin Molex (550mm+95mm) / FDD (+95mm)||2 / 1|
|4 pin Molex (550mm+95mm+95mm)||3|
All cables are very long, but the distance between peripheral connectors has been kept short. Such connectors should be close to 15 cm apart. The main ATX, PCIe, and EPS cables use 16AWG wires for lower voltage drops, while all other connectors use standard 18AWG gauges.
Since this PSU features a single +12V rail, we do not have anything to comment on when it comes time to talk about its power distribution.
