Hello everyone, 

Continuing on with our PSU lineup, we’ve included the updated design CX-M series PSUs (450W, 550W, 650W, 750W). Here are a few highlights:

• A rifle bearing fan ensures longer life than conventional bearings. Low noise, more quiet - regardless of whatever you're doing on your computer.  
• Cleaner, easier semi-modular cable management with single/dual EPS12V connection.
• Compact size of 140mm long total - the CX-M series offers great flexibility in your build configurations. 
• 105°C Japanese Electrolytic Capacitors means consistent power with trusted reliability.

Click 450W, 550W, 650W, 750W for more information. We’ve put together a quick FAQ below.

Q: Is this PSU compatible with the RTX 30 Series?
A: If you do not have any power hungry devices or intention to overclock, then yes the 650W (RTX 3070) and 750W (RTX 3080/3090) should be compatible. If you are the contrary, then we can only recommend the 750W with a RTX 3070 as it provides the necessary wattage headroom for power hungry devices and overclocking.

Q: What kind of cables come with the PSUs?
A: The only sleeved cable is the ATX 12V/EPS 12V connector. The rest are the flat, black ribbon cables.

Q: Which ones have the single connector and which ones have the dual?
A: The 450 and 550 are the Single EPS12V Connector and the 650 and 750 are the Dual EPS12V Connectors.
