Corsair CP-9020178-UK RM650x 80 PLUS Gold 650 W Fully Modular ATX Power Supply - Black

Product Information

Even overclocked to the max with those parts and both bits under a heavy load you will barely breach 450 watts. Under a more typical load such as gaming where both bits are rarely maxed, I expect you will be closer to 350 watts, so a nice spot on the efficiency curve. Corsair RMx series power supplies give you extremely tight voltage control, quiet operation, Gold-certified efficiency, and a fully modular cable set. We measured acoustics from one meter away, inside a small, custom-made anechoic chamber with internals completely covered in sound-proofing material (be quiet! The latter is a Taiwanese company, with factories in China, and provides products to several high-end brands including two well-known ones.

The new Intel specification requires better efficiency at 2%-10% load and new timings (T1 and T3 to support modern standby mode). From individually sleeved cables in a variety of color combinations to 12-pin micro-fit GPU cables and 12VO motherboard cables, complete your build your way. jonnyguru said:Since moving from being a reviewer to someone working in the industry, I've learned that 75% of what is said in reviews, including a lot of the stuff I have said in reviews, is total B. CORSAIR offers a ten-year warranty on all RMx series power supplies, your guarantee of reliable operation that will last across several system builds.We should also note that with 230V input, for which we have test data for the 650 G2, the RM650x clearly leads with a 3. The Corsair RM650 is a fully modular power supply, able to support a potent system thanks to the two EPS and four PCIe connectors that is equipped with.

We would like to see higher than 70% efficiency with 20W load, though the PSU performs well in the other three tests. Unfortunately, we didn't test the EVGA 650 G2 with 115VAC input, so we can only compare the RM650x to EVGA's 650 P2. CORSAIR RM series power supplies are built with the highest quality components to deliver 80+ Gold efficient power to your PC. The same conditions of the above graph apply to our measurements, though the ambient temperature was between at 28 °C (82. Nonetheless, the RM650 scores higher efficiency under super-light loads and it also supports Windows 10's Modern Standby mode.

In the table below, you'll find the power consumption and voltage values of all rails (except -12V) when the PSU is idle (powered on, but without any load on its rails), and the power consumption when the PSU is in standby mode (without any load, at 5VSB). In the following tests, we measure the RM650x's efficiency at loads significantly lower than 10 percent of its maximum capacity (the lowest load the 80 PLUS standard measures). We take four measurements here: one each at 100, 250 and 1000mA, and one with the full load the 5VSB rail can handle. The ATX specification states that 5VSB standby supply efficiency should be as high as possible, recommending 50 percent or higher with 100mA of load, 60 percent or higher with 250mA of load, and 70 percent or higher with 1A or more of load.

The time has come to take a detailed look at the smallest member of the line, the RM650, which as the model number implies, has 650W max power. Rm PSUs utilize industrial-grade, 105°c-rated capacitors for superb performance and reliability, backed by a ten-year warranty. The fan does not even run when the total system load is under ~300 watts which is nice and helps keep the computer quiet. On top of that, it uses a micro-controller in the fan control circuit so Corsair can easily tune the fan's speed and provide the ideal fan speed profile.This site is a free online resource that strives to offer helpful content and comparison features to its visitors. Nevertheless, Elite products have been proven reliable so far, and this is why most brands prefer them when it is too expensive to use Japanese caps. CORSAIR RM650x Series fully modular power supplies with EPS12V connectors are built with the highest quality components to deliver 80 PLUS Gold efficient power to your PC,with virtually silent operation. PLUS Gold efficiency reduces operating cost and excess heat, and Zero RPM fan mode ensures virtual silence at low and medium loads. If its the build in your Sig, so 4770k + GTX1080, you will get nowhere near 590 watts those calculators gave you.
