Helping to end the absolute dearth of high-quality modular PSUs in the 600w range, Corsair has just launched a 650w modular unit.

Dubbed the HX650W, the new unit features an 85%+ Bronze efficiency rating and all the necessary connectors for a modern SLI/CrossFire system.

“The Corsair HX650W is ideal for enthusiasts and gamers who are looking for a highly efficient, quiet, modular power supply, but don’t need the higher wattages offered by the other PSUs in the Professional Series” said Jim Carlton, VP of Marketing at Corsair.

We agree. Most do not need the 700w (or more) being flogged for those who happen to want modularity. The HX650W should offer tremendous price/performance with great convenience, which makes it a good idea for new enthusiast builds.

The boys at OCZ have just announced the immediate availability of the Z Series line of power supplies which have received the prestigious 80+ Gold certification for offering 90% or better efficiency.

The result of nearly two years of research within the technology group’s power division, the new Z Series offers 850W and 1000W units with modular variants available for a small price premium.

Rounding out the product line, OCZ has also released two 80+ Silver-certified units at 550W and 650W respectively.

Gold-certified Z Series units can be found on Newegg:
OCZ Z Series 850W (OCZZ850): $219
OCZ Z Series 850W Modular (OCZZ850M): $239
OCZ Z Series 1000W (OCZZ1000): $289
OCZ Z Series 1000W Modular (OCZ1000M) $299

There is no word on pricing or availability for the remaining Silver-certified models, but we imagine they can’t be far off.

It takes stones to buck the system and throw tradition to the wind, but Antec seems to have grown quite a pair lately. The company’s latest line of power supplies don’t follow the size requirements in the ATX specification, and have gone quite another direction. The current physical dimensions for power supplies date back to 1987 and the arrival of IBM’s PS/2 form factor systems from which ATX later evolved. It’s been 22 years since power supply size has changed for consumers, and Antec wants to lead that charge.

Antec’s new line of power supplies adhere to what they deem the CPX form factor. Instead of the standard 3.4″ height, Antec’s latest PSUs are 120mm tall. That’s 4.72″–too big to fit in any standard case without serious modding. In fact, only three cases on the market now are compatible: The Antec Twelve Hundred, P183 and P193. Why build and market a power supply that doesn’t fit in standard cases?
