In the past, many people have judged the quality of a PSU on its weight and size of internal components. However, with many manufacturers moving on to newer and more efficient ways of designing their PSU's, it has become increasingly obvious that this is no longer a reliable method for gauging a power supply's quality. By looking inside the M1000 we should be able to identify some of the components used and get a good feel for the overall build quality of the unit.
However, Coolermaster has attempted to avoid any potential cooling problems by installing two heavy-duty aluminium heatsinks that are finned in a way that compliments the direction of airflow through the unit. Of course, only the testing over the next few pages will show if these measures manage to keep temperatures under control.
Due to the limited vertical clearance available inside the M1000, Coolermaster have opted for two low-profile capacitors instead of a single full-height capacitor. Unfortunately the capacitors had no distinguishing marks, so I was unable to verify their place of origin or quality.
Cables & Connectors
The modular power supply is one of those inventions that has the PC enthusiast communities split down the middle. Some think that the modular design is a great design - keeping the inside of your PC tidy while also maximising airflow. Others believe that it is unreliable and can cause increased resistance where poor connectors are used. Of course not all modular PSU's are made equal, so let's see what the M1000 has in store.
Coolermaster have gone for their own proprietary 5-Pin flat connector design for use with the Molex and SATA connectors, but have stuck with the tried and tested 6/8-Pin PCI-E style connectors for powering the PCI-E cables. Both of these methods offer extremely sturdy connections that should have minimal impact on performance.
The ATX connector on the M1000 is native 24-pin. However, as you can see above, a small block of 4 connectors can be broken off to switch the connector to 20-pin, thus make it compatible with older motherboards. As many motherboards still make use of the P4-12v 4-Pin connector, Coolermaster have also chosen to include two separate cables for P4-12v (4-pin) and EPS12v (8-pin) standards.
