There have been quite a few high quality power supplies released in the last month and today we take a look at another new one from Corsair, the SF1000L. This is a fully modular SFX-L form factor unit, offering 80 Plus Gold Certification and high levels of build quality across the board.

Right now this power supply is available from Overclockers UK For £219.95 inc vat (HERE). While we will take a closer look when we open the unit later in the review, Corsair are keen to point out that the adoption of Japanese capacitors and low noise PWM fan ensures long life and reliability, they are also backing this unit up with a 7 year warranty. Not quite at the highest levels we see from other manufacturers such as Seasonic (12 years), but it should provide coverage for two to three system upgrades.
