Installation
I installed the PC Power & Cooling Silencer 750 inside my Cooler Master Cosmos case, the installation only took a couple of minutes.
As this power supply doesn't feature modular cabling it will require a bit more effort to keep your case tidy.
Testing and conclusion
To test the performance of the Silencer 750 I installed the PSU in my system and checked out the performance of the +12V, +5V and +3.3 voltages under load and idle conditions to see if these are in line with the official ATX Voltage Specifications.
The +12V and +5V rails are measured with a digital multimeter and the +3.3V line is measured by Asus PC Probe. The idle measurements are taken with by booting the system into Windows XP and letting it rest for a couple of minutes. Load measurements were done by loading up different benchmarks and programs to stress the CPU, graphics card and memory.
The voltage regulation is pretty good with no noticeable drops, expect some small 0.01V fluctuations on the +12V line.
Perhaps it's also interesting to take a look at how the Silencer 750 performs when you hook it up to an expensive Chroma 8000 ATE machine. PC Power & Cooling can ship such a test report with your Silencer 750 but it will cost you $20, which is a bit too expensive to make it worthwhile.
Here's a look at the results:
As you can see the PSU has a pretty high efficiency of 85.06% and a peak output of 836.3W - which is more than 10% more than the PSU is rated at. The voltage regulation and ripple is also pretty good. I don't have the multi-thousands of dollars equipment to verify these results but reports from colleagues indicate that the Silencer 750 does indeed perform really well.
The PSU is called Silencer but that name is a bit misleading. While the PSU is one of PCP&C's more quiet solutions it's definitely not the most silent PSU on the market. At idle and moderate loads the PSU is relatively silent but under heavy load and high temperatures it gets kinda noisy.
The Silencer 750 can be bought on PCP&C's website for $189.99, in Europe I was able to find it for about 142EUR. This product does its job exactly as advertised, it has a high efficiency, good voltage regulation, lots of power, plenty of Molex and Serial ATA cables and supports all the latest hardware.
If you're in the market for a beefy 750W PSU I definitely recommend the Silencer 750, you won't regret it.
The Good Stuff
- Powerful, lots of Watts and 60A +12V rail
- High efficiency
- Good voltage regulation
- Plenty of connectors
- Nice build quality
- 3 year warranty
The Bad Stuff
- Longer than average PSUs, may not fit in all cases
- Gets kinda noisy under high load and high temperature
I give the PC Power & Cooling Silencer 750 PSU a 9/10 and our Seal of Approval.
