Flex ATX replacement for Dell XPS
The Replace Power SG33G5 is a new 350 W Flex ATX power supply built to fit Dell XPS 8300 and 8500 systems. It replaces the original 82WHM, RH8P5, 6GPR9, 7P3WV and FVGCW units. The single-fan design delivers standard ATX power in the compact Flex form factor required by those chassis.
Upgrade from 220 W to 320 W originals
This unit steps in when the factory 220 W, 250 W, 270 W, 300 W or 320 W supply fails or cannot support added components. The extra headroom helps when a discrete graphics card or extra drives are installed. It is not for builders who need higher wattage than 350 W or a different form factor such as standard ATX or SFX.
Direct swap with Dell connector match
Installation is a direct swap: remove the old unit, fit the SG33G5 using the existing screws and connect the same motherboard and drive cables. The Dell-specific pin-out matches the original 82WHM series, so no adapters are required. The only common issue is forgetting to seat the 24-pin and CPU power connectors firmly before closing the case.
