Do graphics cards need their own power supplies? Sirtec believes that they do. At the Computex show here, the company is pitching a dedicated power supply for the latest generation of graphics cards. So far, the company has not signed any distribution agreements, but company representatives say they're hopeful.
The "High Power" PSU will ship in three different ranges: 350, 400, and 620 watts, enough to power an individual graphics card or a pair running in SLI mode.
Today's graphics cards are powered by the PCI Express bus, and often an additional power connector that runs from the same system power supply. Sirtek's argument is that next-generation PCI Express 2.0 systems could require about 300 watts per card, and that even the increased power limits offered by the PCI Express 2.0 standard won't be enough to adequately power those cards. In addition, the system PSU could become overstressed; it makes more sense to divide the power supplied to the system and cards over multiple units, a Sirtec spokeswoman said.
The PSUs are about the size of a CD-ROM drive, deliberately so, the spokeswoman said. They're designed to fit in an optical drive bay, and accept power via a standard notebook connector that would plug into the wall. They don't include cooling functions, however, so the case must be already adequately ventilated.
The Sirtec representative declined to disclose pricing or a possible ship date. "But we're hopeful," she said.
