550W GTR Power supply with 38A/12V?

[eva2000]

Anyone heard of this power supply before ? Noticed the 12V has pretty beefy @ 38AMPS so picked one up to try on PCI-E SLI system





Specs:

- 550w PSU has 3x 80mm fans and sleeved ATX 20 + 4-pin cable (suits both 20 & 24-pin boards). The 24pin cable is parts one 20pin with a 4pin attachment that you can take off for 20pin action. You can see it in above pics
- 8x HDD, 2x FDD, P4 power & 2x SATA connectors, all bar SATA are neon green UV sensitive
- ATX lead also has neon green mesh sheath, 175d x 150w x 85 h
- Aluminium chassis, fans are temperature-controlled & speed adjustable with knob on back. Low speed fan setting is virtually inaudible, while high speed is not that loud at all probably less than Sunon 39cfm fan.
- Very quiet with fans at lowest speed setting
- Rails = +3.3v - 30A, +5v - 32A, +12v - 38A, +5vSB - 2A
- No 240v power cord is included
