To utilize the second ATX 4+4 connector, you will have to give up one of your PCI-E connectors and possibly the ability to utilize triple GPU's. Though I still recommend somewhat over-speccing the PSU, depending a bit on its optimal efficiency curve, to allow for ageing and improved thermal/noise situation and so on. A couple of the polymer capacitors are supplied by Nichicon, ensuring that only capacitors from Japanese companies can be found in the HX850. Build quality is high, as we would expect, and the paint work is quite deep and doesn't scratch easily.
AnandTech tests a good number of power supplies each year, mostly in the popular power ranges (650-850W) with a few reviews now-and-again for small form factor parts or larger behemoths.
The bump from 80Plus Silver to Gold was very nice to see and the unit does a great job showing the increased efficiency. The fan was relatively quiet thorough the entirety of our room temperature testing, reaching high noise figures only when very heavily loaded. within its nominal load range (20% to 100% of the unit's capacity) and gave us fairly good efficiency readings under low loads.
This TekSpek explains what Green Computing is, what it means to the consumer, and how energy-efficient components can be beneficial in the home. Since our test equipment's limits are greater than that of the Corsair HX850 850W, we can test it to the maximum. KitGuru says: The Corsair HX850 Platinum is a fantastic power supply, built to the highest standards.
The unit is finished to a high standard and Corsair have been careful to omit all colour from the power supply so it can easily match any schemed system build you are planning. Our load tests utilize a couple of FAST ATE active load testers and a variety of other equipment such as an oscilloscope, power conditioner, temperature probe and a power consumption meter. Please provide your contact information and any other relevant details and a member of our team will contact you shortly.
This is a technique that becomes more and more popular lately and significantly reduces noise output at low loads since the PSU goes fanless when the thermal load is low. The most apparent upgrades of this latest revision are 80Plus Platinum efficiency levels and a fully modular design, plus an improved (10 year) manufacturer’s warranty. For the testing of PSUs, we are using high precision electronic loads with a maximum power draw of 2700 Watts, a Rigol DS5042M 40 MHz oscilloscope, an Extech 380803 power analyzer, two high precision UNI-T UT-325 digital thermometers, an Extech HD600 SPL meter, a self-designed hotbox and various other bits and parts. Targeting computer power supplies, it awards PSUs that are able to achieve an energy efficiency of over 80 per cent at varying workloads and a power factor of 0.
Easy Installation: The fully modular DC cables make builds and upgrades easy, with clean, great-looking results. Today to test the power supply we have taken it into our acoustics room environment and have set our Digital Sound Level Noise Decibel Meter Style 2 one meter away from the unit. Only the heatsink for the primary inversion circuit stands out, extending to form a small array of fins to increase its dissipation surface. It is getting very hard to distinguish the bad, the good and the great units simply from voltage regulation as could have been done in the past.
Great Deal
