Seasonic Gold Series X-750 Power Supply Review

Manufacturer: Seasonic

A Detailed Look

The Seasonic Gold Series X-750 power supply features a black matte finish and measures 160mm (6.3”) deep. It uses a single 120mm fan on the bottom for cooling.

The backside panel features an open grill and includes a power receptacle and master On-Off switch.  The honey comb grill allows air to exhaust out of the power supply for cooling the internal components with minimal turbulence and noise.

The X-750 Gold uses a high quality 120mm, Sanyo Denki San Ace fan (9S1212F404) that incorporates dual ball bearings for enhanced reliability and long life. The 7 sculptured blades are designed to optimize airflow and reduce noise.  The fan features Pulse Width Modulation (PWM) to integrate with the variable speed Seasonic Hybrid Silent Fan Control circuit.

One of the really nice features of the X-Series Gold PSUs is the ability to operate in either S3FC fanless-silent-cooling mode or S2FC silent-cooling mode.  A small two-position selector switch on the front panel allows selecting Hybrid (S3FC fanless-silent-cooling mode) or Normal (S2FC silent-cooling mode). The Hybrid S3FC mode is designed to turn off the fan at lower power levels and the Normal S2FC mode keeps the fan running all the time.  The high efficiency design of the X-Series Gold also helps by generating less waste heat. And if you aren't abscessed with running fanless and prefer a little air movement with a virtually silent fan, then the Normal S2FC silent-cooling mode is for you (and me)!

Seasonic's PSU's are excellent. The only brand I use.

Then you should maybe not judge things by their brand like a moron and start buying PSU's from other companies.

I have had this unit for a couple of months now and I have had zero problems so far. I got it at newegg on a super sale for $107.50 delivered to my door. It is overkill for my Sabertooth R2 8350 (4.5), MSI 7850 (1000 and 1250), 2 7200 rpm HDD, 1 Vertex4 128 GB, LiteON BD burner and 8 PWM fans. The most I seem to be using is a little over 350 watts and that is when I am ripping a BD disc and converting it to an MKV file about half the size. I had higher overclocks on both my CPU and GPU but I backed them down to a point where they run close to normal temps. I do believe that in order to obtain high stable overclocks you need a very good power supply and this is one.

I have this KM3 baby. Very solid power under load and keeps system running over minor power interruptions. (e.g. thunderstorms)

Really, really love this beast.
