LEPA Gold Series 750W Power Supply Review

Manufacturer: LEPA

Introduction and Features

LEPA is a relatively new player in the PC power supply market and they continue to expand their power supply offerings with the introduction of a second generation Gold Series 650W, 750W, and 850W PSUs.  LEPA also offers five other power supplies in the original G Series ranging from 500W all the way up to 1600W! We will be taking a detailed look at LEPA’s new Gold Series 750W PSU in this review.

Up until now, the LEPA name has traditionally been considered a house-brand for Enermax but the new LEPA Gold Series is manufactured by Channel Well and not Enermax – interesting. ECOMASTER is the authorized US agent for both Enermax and LEPA brand products.

PSU Testing Methodology

Establishing an accurate load is critical to testing and evaluating a PC power supply.  PCPerspective’s power supply test bench can place a precise DC load on the PSU under test.  Each power supply is tested under controlled, real-world conditions up to its maximum rated load (at 40ºC), using both 115 VAC and 240 VAC line voltage.  Our current suite of tests includes:

• DC Load Regulation
• AC Ripple and Noise
• Efficiency
• Differential Temperature
• Noise

The LEPA Gold 750W power supply was evaluated on both features and performance.  A full range of equipment was used to test the power supply under controlled load conditions. 

• (2) CSI3710A Programmable DC load (+3.3V and +5V outputs)
• (4) CSI3711A Programmable DC load (+12V1, +12V2, +12V3, and +12V4)
• (2) 200W Precision resistor load bank (+12V5 and +12V6)
• Switchable precision resistor load bank (-12V and +5VSB)
• Agilent 34401A digital multimeter (Accuracy ±0.0035% vDC)
• Extech 380803 Power Analyzer (Accuracy ±0.5% of full scale)
• DS1M12 "StingRay" digital oscilloscope (20M S/s with 12 Bit ADC)
• Powerstat Variable Autotransformer, 1.4 KVA, 0-140 VAC
• Extech Model 407738 digital sound level meter (Accuracy ±1.5 dB)

Seems like a very reasonably priced contender in the 750W range of 80+ Gold PSUs. Have to say that because of this review I certainly would consider it as a replacement or upgrade [situation-pending]. & Thanks for the review.

The cooling is ridiculous inside this one. The fan has to spin quite fast even at moderate load.
Add the fact that the fan itself is complete crap and you get one of the loudest PSU i've ever heard... It's louder than an overclocked GTX570.
I'm really considering voiding my warranty just to change the fan and those cooling plates if the screws are accessible.

The screws ARE extremely easily accesable... to change the PSU fan, ALL you need to do is to unscrew 4 screws and take out the shroud... though, BE careful with that. Make pretty damn SURE you discharge the capacitors before you open up your unit. There's deadly charge can that be hidden behind those two big primary capacitors.

Cant confirm that.
I have an absolute silent machine (you cant tell if its on or off unless looking at the LEDs or monitor)
running watercooling with external fanless radiator, gtx670 with 3 92mm silent fans and MB controlled noiseblocker case fans 11dB, and i cant hear the psu fan.

I even unplugged all case fans and stopped the gpu fans manually and still nothing from the psu...

Of course running a cheaper/older case with top mounted psu (instead of bottom) and not enuf airflow in a cramped case would make any psu-fan turn up on rpm...
