The Corsair CS650M is very nicely finished, in plain black with white and green product branding on the sides.
The large black fan is visible behind the black metal grill. We will take a closer look at the fan when we crack open the unit, shortly.
The unit passed our ‘screwdriver’ stress test, which involves running a Philip’s head driver down the side of the chassis with weak to modest pressure. How often have you accidentally hit a power supply with some tools during a system build phase?
One side of the power supply is vented to aid with airflow. At the side is a power connector and switch.
This isn't a pure modular design, the main ATX and EPS cables are hardwired into the chassis. The modular panel only takes up around half of the available space, and each area of connectors are clearly labelled. The Peripheral and SATA cables are all 3+3 pin connectors and the PCI-E and 4+4 CPU connectors are 4+4 pin.
The Corsair CS650M can deliver up to 612W via the single +12V rail.
Good value, looks nice too. quality power supplies
I bought a builder series power supply from Corsair and had to return it twice, it was emitting a horrible pitch under load. is this just related to a batch of bad units, or a common corsair problem?
It is a common problem with some of them, not sure of the exact details Harris, but check out this search https://www.google.co.uk/search?client=opera&q=corsair+power+supply+whines&sourceid=opera&ie=utf-8&oe=utf-8&channel=suggest
Its called ‘coil’ whine – its a fairly common issue with Corsair, but it depends on who their partner is which is confusing for people. CWT can do it, but they used to use Seasonic and they don’t. personally id just pay more for Seasonic all the time.
my mates builder series also whines when he loads his 7950. he is on his second one now.
