80 PLUS® Bronze certified efficiency Integra R2 PSUs meet the 80 PLUS® Bronze specification for providing power with an efficiency that is typical of PSUS with much higher price points. Additionally, because Integra R2 PSUs generate less heat, they provide power at lower fan speeds, which results in reduced noise levels.
Excellent Electrical Performance Fractal Design Integra R2 Series PSUs feature excellent DC voltage regulation and ripple suppression: they can deliver their full-rated wattage continuously even with an intake temperature as high as 40°C.
Compliant with the latest standards Integra R2 PSUs are compliant with the latest PC PSU standard: ATX12V 2.31.
Extremely short 140 mm case Integra R2 PSUs are only 140mm long, which accommodates the smallest ATX-compatible computer cases on the market.
Silent, temperature-controlled 120mm fan Generally, larger fans move more air with less noise than smaller fans: Integra R2 Series PSUs are equipped with a large, low speed, temperature controlled 120mm fan, which keeps noise level down.
Extra-long ATX12V cable Integra R2 PSUs are equipped with a 650mm long 12V ("P4") connector cable, which accommodates bottom-mounted-PSU computer cases.

"The efficiency of the power supply is commendable, it achieved 88 percent peak efficiency and meets bronze certification with flying colours. Ripple suppression while far from class leading was also well within the industry rated tolerance levels and the 12V rail in particular was strong."
"Fractal Design was still able to include their cool embossed “snowflake” logo on the top of the unit and there logo on the side is very attractive. Design-wise this unit seems much like Fractal-Design’s higher-end offerings. If you are on a budget the Fractal Design Integra R2 is great choice in a power supply."
"Mit dem Integra R2 hat fractal design ein leistungsfähiges Netzteil für die preisorientierten Käufer auf den Markt gebracht. Die Performance, Verarbeitung und die Geräuschkulisse kann sich sehen lassen. Die Ausstattung, bzw. das Zubehör ist ausreichend und preisbewusst ausgewählt. Für einen Preis von etwa 70€ erhält man ein qualitativ hochwertiges und leistungsfähiges Gerät."
"I think that the key feature of this unit is its extra-small length of only 140 mm, which makes it compatible with very small chassis, given their PSU choices are very limited.[...] Finally, I think the Integra R2 750 W rightfully deserves our budget award because it achieved a top price/performance score."
"The Fractal Design Integra R2 750 W proved to be an excellent mainstream power supply, with very good efficiency, voltage regulation, and ripple and noise levels for a product targeted at this segment, at an unbeatable price (USD 80). One of the highlights of this power supply is its depth. It is only 5.5" (140mm) deep, fitting some small form factor (SFF) cases that require power supplies with this dimension."
"A Fractal Design Integra R2 750 W provou ser uma excelente fonte de alimentação para o usuário médio, com ótima eficiência, boa regulação de tensão e baixos níveis de oscilação e ruído para um produto direcionado a este segmento, e um preço imbatível (US$ 80, nos EUA). Um dos destaques desta fonte de alimentação é o seu tamanho; com apenas 140 mm de profundidade, ela cabe em alguns gabinetes compactos (SFF) que requerem fontes de alimentação com esta dimensão."
