X-bit: 3 ASUS PSUs tested

A-55GA: AcBel design which looks like a Real Power Pro 550W
P-55GA: Delta design similar to this Antec BP550Plus (http://power.zol.com.cn/119/1198279.html)
U-75GA: A much better Delta, you can call it GPS-750AB, or Antec EA750 ;)

Good to have you back Oleg, but I can't agree with you on some points
The first two PSUs are similar to each other and are meant for mainstream PC configurations. They don’t look like a good buy to me because their parameters are not exactly good and their specified output power is overstated (the real effective output power of these PSUs is about 400W).

The A/p 55GA seems group regulated and it shows. Also, it seems like ASUS set a tight budget. Caps are a bit iffy (FSP like). Seems like an older OEM design used for Dell units.

You can see a marked difference when it comes to the 750W unit, which is indy regulated by looking at the 3 filters on the secondary side (numbers prove it).

The two 550Ws are for the "mainstream" and cutting costs. The 750W IMO is just a showcase for ASUS, though Antec might want to sell many under "EA750" name.
Yeah, long live the indy design.

I just wrote up a review of that Acbel unit.

You mean the earlier Real Power or the ASUS A-55GA?
