The SmartPower 2.0

Antec SmartPower 2.0

Those of you who are fans of modular PSUs are going to love the TX1050B. Antec decided to include their newest modular design, the SmartPower 2.0, a 500W modular PSU.

Featuring ATX 2.01 compliance, the smartPower 2.0 picks up where the Antec NeoPower 480 left off. Without going into great detail here (I’m waiting to review all Antec’s PSU’s at one time. I will touch on the improvements the SmartPower 2.0 shows over the NeoPower 480. Other than the obvious 20W difference, the SmartPower shows 70% efficieny whereas the NeoPower was limited to 60%. The SmartPower also ships with a wide assortment of cables including 2 seperate PCI-E power cables for those of you running dual graphics or SLI solutions.

One major difference you may notice from the NeoPower is the use of two 80mm fans for cooling the power supply where the NeoPower used a single 120mm fan. i honestly did not notice much of a noise difference, and my rails were rock solid using ASUS Probe to measure voltages, but as unscientific as software programs are, I’d rather wait and use a more professional method of recording voltage readings.
