Why you can trust Tom's Hardware Our expert reviewers spend hours testing and comparing products and services so you can choose the best for you. Find out more about how we test.

SilverStone has a huge portfolio of SFX and SFX-L products since it is a pioneer in this form factor. The SX750 is not among its best offerings, though, and it needs several changes to increase its performance and become competitive enough to meet products like the Corsair SF750 Platinum eye-to-eye. It has good build quality, using top-notch Japanese electrolytic caps and a double-ball bearing fan which will easily cope with harsh operating conditions. Still, the SX750 needs more tuning to achieve higher efficiency levels. Moreover, the fan speed profile could be more relaxed and an efficiency boost will make this easier since thermal loads will decrease.

There are not many choices in the 750W SFX category. So far, the Corsair SF750 Platinum dominates this category, and if you need more power, there is also the Cooler Master V850 SFX Gold, which we didn't have the chance to evaluate yet. The SilverStone SX750 has many good aspects, but it needs several changes to increase its performance and get closer or even surpass the SF750 Platinum. If you need more power and your chassis can accommodate an SFX-L unit, you could also take a look at the SilverStone SX1000 Platinum.

    The review (and manufacturer website) says there are four 8-pin PCIe connectors. I wish I had read the review with enough attention at the time, as it says "only three sockets for EPS and PCIe cables".

    I bought the PSU (and have been very happy with it earlier) but now later got "lucky" in the GPU drought with a GPU that wants three PCIe power cables. A dumb non-native speaker like me didn't realize there's a difference between socket and connector, especially when manufacturer site only uses word "connector". CPU eats one, so two are left. Sure, I can "power" all the GPU sockets when using the split-ended PCIe cable. But still I feel a bit uncomfortable reading the small print from manufacturer manual about maximum power draw and voiding warranty: "dual PCIe 8pin connectors that exceed 375W total power draw (300W from two PICe 8 pin connectors + 75W from PCIe motherboard slot)".

    So far, things have worked well, GPU power draw stays just below 360W on high load. There are not many options for SFX-size PSU with so many PCIe sockets...
