Great PSU, personally for my build I wished the modular cables were easier to bend or orientated differently, but I got them to work so 5/5

This is the SFX-L version ... an extra 30mm longer than the others ... with a Silent running 120mm fan with intelligent semi-fanless operation (according to silverstonetek).

My ML07B was one of the earlier versions (pre release of the SFX-L) so its in-take grill was set up for the older versions. This forced me to dremel my case so that it has a bigger air in-take hole.

Edie2: don't forget to turn the PSU on ... especially when working with the ML07B. Having to take everything out just flip a switch is a real drag.

This is one of the best, if not the best sfx psu. love the modular flat cables, and the new 120mm super quiet fan. i am gald i got this instead of the smaller sfx silverstone sells. The fan makes a big difference. 500w plenty power. The fan only activates if it reached over 48 deg, i believe.

Very impressed by this power supply. Jonnyguru agrees.

I love the SFX-L power supply format. It's tiny, great for small builds. Frees up a lot of space. And the fanless settings under low load are wonderful and make for a very quiet computer. But when it does come under load, the 120mm fan works quietly and efficiently.

This power supply was great for overclocking.

There is not much choices on sfx psu out there. I opt for this one because of its fan: it is running only above 41°C which means it is completely silent at idle. But I can hear from time to time some jinglings.

Your typical 500w modular power supply, fits nicely in the Silverstone sg13b case(obviously), nothing else to say. Taking off 1star for the stiff connnector on the cable that takes A LOTS of effort to put in and take out.

Good for SFX-L form factor.

Even though there were no Node 202's with power supplies in my country, I would have bought the version without one. So that I could fit this one in. With current build, the PSU have never ever yet powered up it's fan (which means, I do not really know if it works...).

Is this PSU overkill for current system? YES, I KNOW!

Will it be overkill after dGPU installed? Nope.

Why not Integra M? Could not acquire in my country and I am willing to sacrifice something for higher efficiency.
