Best Power Supply Under 100 – A good power supply unit is an important component for a good overall PC build. For budget PC builds, it is best to allocate a portion of the budget to a trusted PSU to ensure safety and long life of components
A larger power supply like your 1000-watt PSU has more wattage allocation, but it doesn’t necessarily mean it’s more powerful. Your CPU and GPU will never take up more power than it actually needs.
A smaller size PSU can be more cost-efficient depending on the type of rig you’re building. If you go for a high wattage psu in low budget, the rating will be probably bronze and not gold. If you want both high wattage with gold rating, then you need to spend more.
We have just compiled a list of the 5 best PSUs under $100 that we recommend in 2021. Narrowing down the choices is in your hands now.

All of Corsair’s CX and CX-M units are made by Channel Well Technology, an OEM that keeps close ties with the company. Basically, the CX and CX-M models are based on a custom platform made specifically for Corsair. It’s even probable that Corsair’s PSU engineering team helped CWT with the design. And that’s why you won’t find this platform used anywhere else except in Corsair products.
The CX750M and flagship CX850M use a different platform than the other CX-M power supplies, including the recently-reviewed CX650M. Moreover, Corsair upgraded the CX-M family last year by increasing the capacity of certain models (the CX600M became the CX650M, for example) and upping the temperature rating from 30ºC to 40ºC.

4.EVGA 500W 80PLUS
- EVGA 500 Watt; Unbeatable value
- 80 plus white certified, with 80 percentage efficiency or higher under typical loads
- Heavy duty protections, including OVP (Over voltage protection); UVP (Under voltage protection, OCP (Over current protection), OPP (Over power protection), and SCP (Short circuit protection)
- Compatibility of the EVGA 500 W1, 80 white 500 W, Power supply 100 W1 0500 KR (100 W1 0500 KR)
High-end products provide prestige to a manufacturer’s name, but the mainstream and mid-level ones pay the bills because they sell in much larger quantities. EVGA knows this and has released a mainstream PSU for the budget user’s small or secondary system at the same time as their new SuperNOVA units. Today’s star, the fresh EVGA Bronze 500 W unit, or 500B, is supposed to get the job done reliably without putting a dent into your bank account. Promising good performance and compatibility with Haswell’s advanced sleep states, we are pretty sure many of you will like this little fellow costing $50.
The 500B features a non-modular design, is 80 Plus Bronze certified, and has very compact dimensions. The OEM behind this unit is HEC/Compucase. This specific manufacturer produces affordable units, and we have actually encountered the same platform in our recent be quiet! L8-500 review. But there are differences between the two units sharing the same platform, and we will make sure to point them out to you in this review.
The Seasonic SFB SFX Power Supply is SFX 12 V v.2.31 compliant and offers important protection features for safe operation. Achieve up to 85% efficiency at 115 V AC at 50% load. The perfect solution for both business and those looking for a high quality and efficient SFX power supply!
Best Power Supply Under 100 – A PSU is the most critical component of a pc build, as it provides power to all components.
Failure to provide power properly could lead to system degradation or even damage but it is rare these days.
It is always recommended to get a good psu from a reputed brand instead of a cheap one. And for $100 you can get a quite powerful psu that is around 700W-850W and is modular in design.
A 700W psu can easily power a mid or high end pc build with powerful graphics card like RTX2080.
