Power Specifications
| EVGA SuperNOVA 1600 P2 Power Specs | ||||||
|---|---|---|---|---|---|---|
| Rail | 3.3V | 5V | 12V | 5VSB | -12V | |
| Maximum Amps | 24 | 24 | 133.3 | 3 | 0.5 | |

A single +12V rail can deliver the unit's full power by itself, which is usually the case in modern, high-efficiency platforms. With a current output just over 133A at +12V, the 1600 P2 is among the strongest PSUs available. It easily covers every multi-GPU configuration we can imagine. The minor rails have enough juice to provide for today's system needs, though the 5VSB rail could be stronger. In a 1.6kW unit, we would like to see at least 4-5A at 5VSB. But apparently Super Flower uses the same 5VSB circuit on all of its high-end platforms.
Cables And Connectors
| Modular Cables | |
|---|---|
| ATX Connector (580mm) | 20+4 pin |
| 4+4 pin EPS12V (740mm) | 2 |
| 6+2 pin PCIe (740mm+145mm) | 10 |
| 6+2 pin PCIe (740mm) | 4 |
| SATA (550mm+105mm+105mm+105mm) | 12 |
| SATA (550mm+105mm / 4 pin Molex (100mm+100mm) | 2 / 2 |
| 4 pin Molex (550mm+100mm+100mm) | 3 |
| FDD adapter (+100mm) | 2 |
The number of available connectors lets this PSU deliver its full power effortlessly. A 1600 P2 owner has access to 14 PCIe connectors along with two EPS connectors, and all are available at the same time. This means you can use the power supply to drive up to seven graphics cards, each with two PCIe connectors, along with a server mainboard. In addition, the number of SATA connectors is huge, and the available 4-pin Molex connectors suffices in most cases.
Regarding cable length, the main ATX lead should be a little longer. All of the other connectors are installed on sufficiently-long cables, which is particularly helpful since such a powerful unit will most likely be installed in a full-tower case. The distance between the PCIe and SATA connectors is satisfactory, but we would like to see 13-15 centimeters (not 10) between peripheral connectors. Finally, the main ATX, EPS and PCIe cables use thicker, 16AWG gauges for lower voltage drops, while the other connectors use standard 18AWG wires.
Power Distribution
Since this PSU features a single +12V rail, we have no comments about its power distribution.

Where are you from that you need all that power? Cybertron?
47C ambients? Must have been sweating your language, please off, or you are language, please me.
One day you need to show us a picture of everything. I've seen little snapshots here and there, but I'd like to see it all in one thread.

The PSU is inside a special-made box (hot-box) for the high temp tests.
Wouldn't your FLIR show that the box is hot?
I already know what happens inside the box thanks to two temperature probes I have installed in it, so no need to use my FLIR on it. However on next review I will try it.
Fair enough. It will be excellent when Tom's Hardware adopts a consistent review standard. Yours was one of the best PSU reviews yet. There's other nitpicks I have but they are nothing major like chart/graph formats could be easier to read.
In your opinion everything held up in close to 50C conditions then?
Dont forget the OFF switch. Arnold is a busy man.
around 45C is much more realistic. 50C are too much for modern chassis. However when needed I crank up the heat inside my hot box to see how the PSU performs. Like in this case that I deliberately exceeded my usual 45C and went to almost 48.
Also note that I'm making a distinction between Watts (W) and Volt-Amperes (VA) although they have the same dimension. The reason is this:

I hope you do the same.
The max power is the combined max power that both rails can deliver. Hence while each rail can go up to 24 A both of them can deliver only up to 120 W (combined). This means that either the 5V rail can go up to 120 W alone (so zero W for the 3.3V one) or the 3.3V rail can go up to 24 A and the 5V at 8.16 A.
In DC we use Watts. VA is for AC. In DC Watts = VA
As for the max voltage yeap this will be fixed.
