Cyrus PSU XR, upgradeable power supply

The PSU-XR builds upon our extensive legacy in Power Supply design. Beginning with the original PSX, Cyrus has always led the field in producing clean, stable and ‘stiff’ external upgrade power supplies. ‘Stiffness’ is essential, Even when heavy loads are applied, the voltage has to remain completely stable. The PSU-XR employs the largest toroidal transformer we have ever used, coupled with some amazingly efficient load management circuits to deliver a staggering amount of power.

We offer free shipping to metropolitan areas on all orders over $100, except for orders containing the following products:

Televisions, Floorstanding speakers, Subwoofers and Package systems.

Shipping on these items will be standard delivery. If you want expedited shipping, an option should be available at checkout.

We try to dispatch all goods within 48 hours however from time to time the stock in store runs out before we have a chance to update the website. In these cases we will contact you if the item will take longer than 48 hours to be dispatched.

We strongly suggest that items are shipped to a business address, or an address where someone can sign for the delivery. On checkout you have the option of choosing Authoirty to Leave. This will not require a signature, but goods will be left at your premise and the delivery company will take no responsibility for them beyond this point.
