FSP Booster X3 300w 12v PSU



FSP have recognised the problem many people have been experiencing with SLI / Crossfire power issues and tackled it head-on. The Booster X3 is an excellent idea, and allows you to continue using you existing power supply without lagging behind (no pun) in the graphics card world.

With voltage fluctuation of only 0.4% when placed under 80% load, the Booster X3 provides more stable rails than a lot of high-end power supplies which is testament to FSP considering the size of the unit.

Let down by only its noise levels under load, and its slightly high price tag of £64 over at Microdirect, the Booster X3 is still a cheaper and easier alternative than to upgrading your existing power supply.


It may also be worth noting that there is no technical reason why the Booster X3 couldn't be used to power a Peltier, and would actually work out as a cheaper alternative than a dedicated Peltier PSU.

+ Stable power (only 0.4% fluctuation)
+ Good efficiency
+ Innovative solution for GPU power problem
+ Allows you to keep your existing PSU for longer
+ Could be used to power other devices such as a Peltier.

- Noisy under full load
- PCI-E cables cannot be plugged in seperately.
- Slightly expensive

Looking to go SLI / Crossfire, but don't fancy upgrading your faithful 400w PSU?

Or maybe you're looking for a way to power that peltier, but don't fancy forking out £80+ for a Peltier PSU?

Looks like a great option for those who wanna upgrade to SLI/Crossfire and have an inadequate PSU

Also maybe someone with an OEM machine who wants to add a meaty GPU/other accessories Quote

How sweet is that; what an awesome idea. I love the front fascia, it looks almost holographic. Great review as usual Jim Quote
