Thermaltake Smart 700W 80+ White Alternatives: 6 Similar Picks Compared
As an Amazon Associate we earn from qualifying purchases. Links on this page are affiliate links.
If you are planning an entry-level PC build, comparing thermaltake smart 700w 80 white alternatives lets you find the right balance of capacity and features. The Thermaltake Smart 700W power supply delivers 700 watts of continuous power, active PFC, and up to 86 percent efficiency with an ultra-quiet 120mm fan. It measures 3.5 inches high, 5.8 inches wide, and 5.9 inches long, and Thermaltake covers it with a 5-year warranty.
You may want a different power supply if your setup demands semi-modular cabling, higher energy efficiency such as 80 Plus Bronze or Gold, or a different brand. Other systems require shorter enclosures for compact cases, higher wattage ratings like 750W, 850W, or 1000W, or larger 135mm and 140mm cooling fans. These 6 alternatives were chosen because their specifications overlap directly with the original unit. They share standard ATX form factors and active PFC, giving you practical options across multiple efficiency tiers, physical dimensions, and power outputs.
Our top pick: Thermaltake Smart 700W 80 Plus White PSU.
Comparing Thermaltake Smart 700W Alternatives
Rosewill 650W Non-Modular 80+ White PSU
The Rosewill 650W Non-Modular PSU delivers 650 watts, giving you 50 watts less capacity than the Thermaltake Smart 700W. It features a narrower width at 5.51 inches compared to the 5.8 inches on the original, though it weighs slightly more at 2.8 pounds versus 2.2 pounds. Both units provide an 80 Plus White efficiency rating, Active PFC, and a 5-year warranty. The Rosewill unit incorporates DC-to-DC design to regulate power. You give up the extra continuous output headroom of the 700-watt supply. Choose this option if your compact desktop build requires fixed cabling and stable DC-to-DC power, provided your hardware stays well within 650 watts.
Apevia Prestige 800W Gold ATX Power Supply
The Apevia Prestige 800W gives you 100 watts more continuous output than the Thermaltake Smart 700W. It steps up from baseline 80 Plus White to an 80 Plus Gold efficiency certification, reducing energy loss during operation. For thermal management, it uses a 135mm fan, which is larger than the 120mm fan in the original unit. However, the Prestige has a longer 6.2-inch chassis compared to 5.9 inches, and it weighs 4.7 pounds compared to 2.2 pounds. It also does not list a 5-year warranty. Pick this unit if you need higher efficiency and additional capacity for a multi-core gaming setup where case space allows.
Raidmax Vortex 700W Bronze ATX Power Supply
The Raidmax Vortex 700W matches the 700-watt continuous output and Active PFC of the Thermaltake Smart 700W. It upgrades your power efficiency to an 80 Plus Bronze rating, exceeding the original model's 80 Plus White baseline. Its chassis has a slightly narrower width of 5.51 inches compared to 5.8 inches, while retaining the same 5.9-inch length. At 2.65 pounds, it is slightly heavier than the 2.2-pound Thermaltake unit. The Vortex does not include the published 5-year warranty found on the Smart 700W. Choose the Raidmax Vortex if you want the same 700W capacity in standard desktop systems while stepping up to Bronze-level efficiency.
Apevia Galaxy 1000W 80+ Gold Semi-Modular PSU
The Apevia Galaxy delivers 1000 watts of total capacity, providing 300 watts more headroom than the Thermaltake Smart 700W. It advances efficiency to the 80 Plus Gold tier and introduces semi-modular cabling, allowing you to disconnect unused cables for a cleaner interior. In trade, the Galaxy is longer at 6.2 inches versus 5.9 inches, requiring extra space inside your PC enclosure. It also lacks modern PCIe 5.0 12VHPWR connectors and does not feature the 5-year warranty specified for the Thermaltake model. You should select the Galaxy if you run a high-draw gaming system using standard PCIe power connectors that requires four-digit wattage and modular cable flexibility.
Apevia Premier 850W Gold Semi-Modular PSU
The Apevia Premier 850W increases power delivery by 150 watts over the Thermaltake Smart 700W. It upgrades efficiency from 80 Plus White to 80 Plus Gold and features semi-modular cabling, giving you detachable peripheral cables rather than fixed wiring. It also adds RGB lighting for visual styling. To gain these features, you accept a larger physical footprint, as its 6.2-inch depth exceeds the 5.9-inch length of the original. The Premier also omits the 5-year warranty listed for the Thermaltake supply. Pick the Apevia Premier if you are building an 850W gaming computer where you want semi-modular management, Gold efficiency, and RGB aesthetics.
GamePower 750W Bronze ATX Power Supply
The GamePower 750W delivers 50 more watts than the Thermaltake Smart 700W and improves efficiency from 80 Plus White to an 80 Plus Bronze rating. It equips a larger 140mm fan compared to the 120mm fan on the original, enhancing airflow across internal components. It is also lighter at 1.1 pounds compared to the 2.2-pound Thermaltake. On the other hand, its 6.3-inch length is slightly longer than the original 5.9-inch casing, and it does not state a 5-year warranty. Choose the GamePower 750W if you need slightly more wattage and Bronze-rated efficiency with a larger cooling fan for a gaming setup.

Frequently asked questions
Which Thermaltake Smart 700W alternatives offer higher energy efficiency?
Several alternatives provide higher efficiency ratings than 80 Plus White. The Raidmax Vortex 700W and GamePower 750W feature 80 Plus Bronze efficiency. If you want even higher electrical efficiency, units like the Apevia Prestige 800W, Apevia Premier 850W, and Apevia Galaxy 1000W carry 80 Plus Gold ratings. Higher efficiency generates less waste heat inside your computer case.
Are there semi-modular alternatives to the Thermaltake Smart 700W?
Yes, models like the Apevia Premier 850W and Apevia Galaxy 1000W feature semi-modular cabling. While the Thermaltake Smart 700W uses fixed cables, semi-modular units allow you to detach unneeded peripheral leads. This leaves more open room inside your PC chassis and simplifies cable routing. Both Apevia options also provide 80 Plus Gold efficiency and Active PFC regulation.
Which 700W alternative fits best in space-constrained PC cases?
The Raidmax Vortex 700W offers a compact footprint measuring 5.51 inches wide, 3.38 inches high, and 5.9 inches long. That chassis width is narrower than the Thermaltake Smart 700W, which measures 5.8 inches wide. If your desktop case has tight clearances around internal drive bays or lower shrouds, choosing a narrower ATX power supply simplifies placement and cable management.
What options provide more wattage than the Thermaltake Smart 700W?
You can step up to several higher-capacity alternatives on this list. The GamePower unit delivers 750W, the Apevia Prestige provides 800W, and the Apevia Premier supplies 850W. For high-draw systems, the Apevia Galaxy reaches 1000W. Additional wattage headroom gives your build stable continuous power delivery without running the power supply close to its maximum continuous limit.
How do cooling fan sizes compare across these power supplies?
Cooling fan sizes differ across models to manage internal thermal loads. The Apevia Prestige 800W uses a 135mm thermal fan designed for quiet operation under heavy system loads. The GamePower 750W includes a larger 140mm cooling fan. Larger fans can move comparable amounts of air through the power supply enclosure while rotating at lower operational speeds.
Do high-wattage options like the Apevia Galaxy 1000W include PCIe 5.0 cables?
No, the Apevia Galaxy 1000W does not include modern PCIe 5.0 12VHPWR cables. It relies entirely on standard PCIe connections to supply graphics cards. If your graphics card requires a 12VHPWR connection, you must use standard multi-cable adapters. This power supply remains designed for high-draw PC components configured around standard traditional modular cable layouts.
Do all listed Thermaltake Smart 700W alternatives include Active PFC?
Yes, all listed alternative models feature Active Power Factor Correction. This includes the Rosewill 650W, Raidmax Vortex 700W, GamePower 750W, and all Apevia models. Active PFC circuitry automatically corrects input power variations and optimizes power factor performance. This engineering standard helps your system maintain stable, continuous DC output across varied AC wall power inputs.
