PC Power & Cooling Turbo-Cool 1KW-SR (1000W)
PC Power & Cooling (PCP&C) is a renowned manufacturer of high-quality power supplies, from quiet models of the Silencer series with wattage ratings beginning at 310W and to the Turbo-Cool 1KW-SR, which I will test right now.
The Turbo-Cool 1KW-SR is one of the largest PSUs we’ve ever tested in our labs. It is 230mm long, which is 90mm longer than a standard ATX power supply. So, if you want to buy this PSU, make sure beforehand that you system case offers at least 270mm of free room (the length of the PSU proper plus at least 40mm for its cables).
The internals of this PSU can surprise a specialist even. There are actually three almost independent power supplies in one case here. In an ordinary PSU there is one power source and a common high-voltage section, the power transformer providing the necessary voltages (even in the above-described Cooler Master the two power transformers work strictly synchronously, thus making up one power source). The only common thing in the Turbo-Cool is the active PFC device. On the vertically standing cards there are three absolutely independent sources, each with its own high-voltage section and its own power transformer. I haven’t seen this kind of PSU design before.
Common too are the cooling heatsinks. These are ribbed aluminum bars placed across the PSU, and across the cards with independent sources, which are fastened to small and rather thin individual heatsinks that transfer heat from semiconductor components. As opposed to the OCZ power supply, these heatsinks have no contact with the PSU cover.
The PSU can sustain a continuous load of 1000W, yielding 864W from its +12V rail (the PSU doesn’t split its +12V power rail into multiple outputs). There are no limitations on the input voltage and ambient air temperature: the 1KW-SR can work at full load with 90VAC voltage and at an up to 50°C temperature.
Peak loads are specified, too. The period of time the PSU can work under such loads is not specified, but it’s usually one minute.
The PSU offers the following cables and connectors:
- Mainboard power cable with a 24-pin connector, 53cm long
- CPU power cable with a 4-pin connector, 53cm
- Two (!) CPU power cables with 8-pin connectors, 55cm
- Four graphics card cables with 6-pin connectors, 55cm
- Two graphics card cables with 8-pin connectors, 55cm
- One cable with two Molex connectors and one floppy mini-plug on each, 40+14+14cm
- One cable with three Molex connectors, 50+14+14cm
- One cable with three Molex connectors, 78+14+14cm
- One cable with three SATA power connectors, 49+16+16cm
- One cable with three SATA power connectors, 80+16+16cm
Two adapters for 8-pin graphics card connectors are included with the PSU. They look somewhat funny at first because they have 8-pin connectors on both ends, making an impression that they adapt nothing.
The cables for peripheral devices have different lengths so that you could connect your HDDs and optical drives in a most optimal way.
