So, who wants a 1,250W PSU?

Your PC not burning through enough electricity as it is? You need a Sapphire FirePSU 1,250W PSU!

The Fire PSU range are workstation grade power supply units that are aimed at ATI FireGL, FireMV and ATI FirePro GPU users. They are jam-packed with high-end features:

• Design For Workstation: Optimized for workstation; AMD Opteron Processors Support; ATI FireGL and FireMV; ATI FirePro
• Multi-Card: CrossFireX Ready; SLI Support
• EPS12V: Provide more powerful and stable environment for critical server-based systems and applications supply
• 80PLUS: Compliant with ENERGY STAR® 4.0 and 80PLUS® efficiency requirements
• PCI-E power Support: Support PCI Express 2.0 and next generation graphic cards with 6+2P (8P) PCI-E connectors

• Worldwide Power Support: Auto-Adjustment for global voltage 100VAC–240VAC
• Active PFC: Improve the power factor up to 0.99 and greatly reduced AC harmonic distortions and save energy
• EMC: Full-scale electromagnetic filtering protects your system against radiation interferences
• Fan Speed Control: 12cm fan with fan speed control for optimal cooling; it is the special design that makes PSU exhaust air flow quickly.
• Protection Guard: Over Loading, Current, Voltage Protection; Under Voltage Protection; Short Circuit Protection; Over Temperature Protection

I know that the GPU market has contracted significantly over the past few months, but I can't see the high-end 1,000W+ PSU market being all that big either.

Unless you have an absolutely monster system, you're not going to need this much power.

A 625W FirePSU retails for around $50, so expect these units to be pricier when their hit retail.
