4 out of 5 eggsLEPA 550W PSU

This review is from: LEPA B550-MB 550W ATX 80 PLUS BRONZE Certified Hybrid Modular Active PFC Power Supply

Pros: *Modular.

*Running an i5-4670K (84W) and a MSI GeForce GTX660 (Min. 550W PSU) without any issues so far.

Cons: The red lining in the pictures is actually a rubber-like fitting that is sitting over the PSU. It makes the PSU look better, but this fitting made it hard to fit the PSU into my mid-tower case without having to bend the divider between the PSU and MOBO. I also had to apply a lot of force while screwing it in.

Other Thoughts: I could have easily taken the fitting off, but one of the reasons I bought the power supply was to stick with the RED/BLACK theme of my build.

The rubber fitting may fit easier with bigger cases, but you can still make it work with the fitting; just be prepared to apply some force.
