How these alternatives differ
Lian Li 750W SFX Gold Power Supply
The Lian Li 750W SFX Gold offers the same 80 Plus Gold efficiency and fully modular design as the SP850, but reduces wattage to 750W. It maintains the compact SFX form factor, making it ideal for smaller cases where 850W is unnecessary. You save space and potentially weight by choosing this lower-output unit. However, you lose the extra headroom needed for high-end graphics cards. This pick suits builders who prioritize efficiency and compactness over maximum power delivery in a tight chassis.
Lian Li SP850 850W Gold SFX Power Supply
This Lian Li SP850 model matches the original in wattage and efficiency, providing 850W and 80 Plus Gold ratings. The key difference is color; this unit is black rather than white. It retains the fully modular feature and SFX form factor. If you are building in a case where the power supply is not visible, this black option provides identical performance. You give up the white aesthetic appeal but keep the same power output. It is a practical choice for builders who prefer a neutral color scheme or cannot find the white version.
EVGA SuperNOVA 750 G2 750W Power Supply
The EVGA SuperNOVA 750 G2 provides 750W of power with 80 Plus Gold efficiency and full modularity. It differs by offering a ten-year warranty, which is longer than typical SFX units. The physical dimensions are slightly larger than standard SFX, measuring 5.9 by 3.4 inches. This unit suits users who need reliable efficiency but can accommodate a slightly bulkier form factor. You trade the compact SFX size for extended warranty coverage and proven reliability. It is a solid choice for compact builds where space allows for a slightly larger unit.
EVGA SuperNOVA 850 G+ 850W PSU
The EVGA SuperNOVA 850 G+ delivers 850W with 80 Plus Gold efficiency and full modularity, matching the original wattage. However, it uses a standard ATX form factor, not SFX. This makes it incompatible with small form factor cases. It includes a ten-year warranty. This unit is for builders using standard ATX cases who need high power without size constraints. You gain significant compatibility with larger cases and a long warranty. You lose the ability to install it in compact SFX chassis. It is best for traditional desktop builds.
SilverStone 700W SFX 80 Plus Gold Power Supply
The SilverStone 700W SFX Gold offers 80 Plus Gold efficiency and full modularity in a compact SFX frame. It reduces wattage to 700W compared to the 850W original. It features a lead-free paint finish and weighs only 3.09 pounds. This unit is lighter and slightly smaller in width. It suits users who need efficient power for mid-range builds in tight spaces. You sacrifice 150W of power for a lighter, more compact design. It is ideal for small form factor PCs that do not require maximum wattage for high-end components.
SilverStone 700W Platinum SFX-L Power Supply
The SilverStone 700W Platinum SFX-L provides superior 80 Plus Platinum efficiency, exceeding the Gold rating of the original. It features a 120mm fan for better cooling performance. The SFX-L form factor is slightly larger than standard SFX. It offers full modularity and 700W output. This unit is for builders who prioritize thermal performance and efficiency over raw wattage.

Frequently asked questions
Is the Lian Li SP850 fully modular?
Yes, the Lian Li SP850 is fully modular. This design allows you to connect only the cables your build requires, reducing clutter inside your case. It shares this feature with the SP750 and other SFX options listed here. This flexibility helps you manage cable routing more easily in tight spaces.
What is the difference between SFX and SFX-L form factors?
SFX-L units are slightly longer than standard SFX power supplies. The SilverStone SST-SX700-LPT is an SFX-L model with a 120mm fan, offering better cooling efficiency. Standard SFX units like the Lian Li SP850 are more compact. You must check your case compatibility before choosing SFX-L, as they require more depth.
Does the EVGA SuperNOVA 850 G+ fit in small cases?
No, the EVGA SuperNOVA 850 G+ is an ATX unit. It measures 7.1 inches in length and is designed for standard ATX cases. It is not suitable for small form factor builds that require SFX or SFX-L power supplies. Use it only if your chassis has ample space for a larger PSU.
Which PSU offers the best efficiency for a 700W build?
The SilverStone SST-SX700-LPT offers Platinum efficiency, which is higher than the 80 Plus Gold rating found in most other options. It uses a 120mm fan for improved thermal performance. If you need exactly 700W in a compact form, this unit provides superior energy efficiency compared to the standard SFX Gold models listed.
Can I use the Lian Li SP750 in place of the SP850?
You can use the SP750 if your components require less than 750W. It shares the same SFX form factor and 80 Plus Gold efficiency as the SP850. However, it delivers lower wattage. Choose the SP750 if you prioritize space saving and do not need the full 850W capacity of the SP850.
Is the Lian Li SP850 available in black?
The Lian Li SP850 model listed here is white. However, Lian Li offers an SP850B variant in black. Both share the same 850W capacity and 80 Plus Gold efficiency. If you prefer a black aesthetic for your build, you can select the black version while maintaining the same compact SFX dimensions.
How heavy is the SilverStone 700W SFX Gold?
The SilverStone SST-SX700-G weighs 3.09 pounds. This is lighter than the EVGA SuperNOVA 750 G2, which weighs 6.6 pounds. The reduced weight is typical for compact SFX units. This makes it easier to install in smaller chassis where minimizing overall system weight is a priority.
