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

Product Information

Sure there are enough Chinese factories with low production standards, and when it comes to capacitors, this can lead to terrible results. 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. Join the experts who read Tom's Hardware for the inside track on enthusiast PC tech news — and have for over 25 years.

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. Just off the top of my head Flextronics, CWT and SuperFlower are all capable of making units that are at least equal to high end Seasonic quality.It is true you want a quality power supply period, more so for overclocking, but suffice to say your RMx unit is fine even when overclocked. We should note here that Elite caps, which are widely used in the RM650, might be manufactured in China, but Elite is a brand of Chinsan. At low and medium loads the cooling fan switches off entirely for near-silent operation, but once the action picks up, the fan activates, ensuring critical component temps stay in check.

We measured acoustics from one meter away, inside a small, custom-made anechoic chamber with internals completely covered in sound-proofing material (be quiet! Completely modular cables means you only connect the cables your system needs, and the wide range of included cables adds broad compatibility with modern graphics cards and motherboards. 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.The scoring that appears on this site is determined by the site operator in its sole discretion, and should NOT be relied upon for accuracy purposes. 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). CORSAIR RMx Series fully modular power supplies are built with the highest quality components to deliver 80 PLUS Gold efficient power to your PC with the cooling power of potent Magnetic Levitation fans. The fan does not even run when the total system load is under ~300 watts which is nice and helps keep the computer quiet. Unfortunately, we didn't test the EVGA 650 G2 with 115VAC input, so we can only compare the RM650x to EVGA's 650 P2.

I want the best PSU, and it seems from your comments the rm650x will give me more confidence in Overclocking. Even overclocked to the max with those parts and both bits under a heavy load you will barely breach 450 watts. CORSAIR RM series power supplies are built with the highest quality components to deliver 80+ Gold efficient power to your PC.will only consume around 10-20 watts idle, likewise for the GPU with remaining system eating another 10-20 watts. 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. We'll send breaking news and in-depth reviews of CPUs, GPUs, AI, maker hardware and more straight to your inbox. 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. PLUS Gold efficiency reduces operating cost and excess heat, and Zero RPM fan mode ensures virtual silence at low and medium loads.

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. For consistent, reliable power and superb electrical performance, each RMx Series power supply features a robust resonant LLC topology with DC-DC conversion, and 105°C rated 100% Japanese electrolytic capacitors.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). Built with all Japanese 105°C capacitors, they’re a great choice for high performance PCs where reliability is essential. Nonetheless, there are some areas where the RM650 takes the lead because it uses an updated platform. Corsair RMx series power supplies give you extremely tight voltage control, quiet operation, Gold-certified efficiency, and a fully modular cable set.
