Stability

PC Power and Cooling Turbo Cool 850W PSU

From the graph you can see the Turbo Cool 860W to have the most stable rails out of all four power supplies displayed. The only voltage fluctuation was on the 3.3V rail and this was only by 0.01 volts.

In terms of their rated voltages, the 12V rail was the furthest out compared with the other three power supplies and the 5V and 3.3V rails each came in at 3rd best.

Efficiency

PF Standby PF Idle PF Load Watts Standby Watts Idle Watts Load
Signature 650W 16 84 91 7 94 139
Commander 850W 24 77 85 9 98 142
RX-8500 850W 20 70 81 6 96 142
Turbo Cool 860W 19 80 86 9 100 143

From the efficiency tests you should be able to see this power supply performing in 2nd place in the PF (Power Factor) tests. This shows that the Turbo Cool 860W is being efficient with the power it’s using by trying to use up every spark of power that it’s consuming.

It did use slightly more power than the other units however, only by a mere amount though.

Noise

Out of all four power supplies so far reviewed, the PC Power and Cooling Turbo Cool was the 3rd most quiet. This is mainly because of an 80mm fan being used instead of lower RPM 120mm. However, I wouldn’t really regard this unit as noisy, as it cannot be heard over our so-called ‘silent’ case fans.

Cost

The PC Power and Cooling Turbo Cool 860W retails at £137.99 at Overclockers. For a premium PSU like this, this price is slightly less than we had expected.

CoolIT Domino i5 Testing

Back in July this year we tested the CoolIT watercooling kit using a heavily overclocked AMD 7750+ BE. It’s performance really surprised us with it absolutely caning the other coolers in question. However, processors have quickly moved on since July and we’ve got the likes of the Intel Core i7 and recent i5 dominating the market. For this reason, we thought some i5 testing using our trusty CoolIT Domino was in order. Let’s see if the performance from the Domino still survives in this day and age…
