Replace Power Supply Mini ITX/Flex for Elanpower rp-2005-00 - Compact

In this review of the Replace Power Mini ITX / Flex power supply, the bottom line is simple: it is a compact, space-saving PSU built for small form factor builds that need up to 350W in a reduced-depth housing. The reviewer found it most valuable for mini-ITX desktops, HTPCs and rack-mount 1U conversions where clearance is tight; the unit's reduced depth and standard 20+4 power connector make it a practical replacement for many slim PSUs. This review focuses on real-world fit, connectors, cooling and which builds benefit most from this compact supply.

Key Features

• Reduced depth: The 150mm x 81.5mm x 40.6mm footprint lets this PSU fit into slim SFF and HTPC cases that cannot accept full-depth units.
• 20+4 power connector: The hybrid 20+4 main connector supports both 20-pin and 24-pin motherboards for broad compatibility with older and newer boards.
• SATA and Molex support: Multiple SATA and a 4-pin Molex connector allow attaching drives and legacy peripherals without an adapter in most compact systems.
• 350W maximum output: With a 350W ceiling this supply handles modest CPU and GPU combinations typical in HTPC and mini-ITX gaming or home office rigs.
• Small form factor design: Engineered as a Mini ITX / Flex ATX PSU, it is intended for slim cases, small desktop enclosures and 1U rack conversions where space is constrained.

Who It's For

The Replace Power Mini ITX / Flex is aimed at builders repairing or upgrading small form factor PCs: mini-ITX desktops, slim HTPC cases and some compact 1U or desktop server chassis. Its reduced depth and standard connectors make it a straightforward swap for many proprietary slim units and older TFX style supplies.

It is not ideal for high-end gaming rigs or workstations that demand large peak power headroom or many PCIe power connectors; users who plan to run power-hungry discrete GPUs or add many drives should look for a higher-wattage ATX solution with explicit PCIe outputs.

Pros & Cons

Pros

• Compact footprint fits in narrow mini-ITX, HTPC and slim chassis where standard PSUs will not.
• 20+4 connector offers compatibility with both 20-pin and 24-pin motherboards for easier swaps.
• SATA and Molex outputs cover common storage and peripheral needs in small builds.

Cons

• With a 350W maximum it can be limiting for systems with power-hungry GPUs or extensive drive arrays.

Our Verdict

The Replace Power Mini ITX / Flex PSU is a practical, value-oriented choice for anyone restoring or building a compact mini-ITX or HTPC system where space is the primary constraint. Its reduced depth, standard 20+4 connector and SATA/Molex hookups make it an effective replacement in many slim enclosures, though builders needing significant GPU power should select a higher-wattage alternative.

Frequently Asked Questions

Will this fit in any mini-ITX case?
It fits most slim mini-ITX and HTPC cases that require a reduced-depth PSU, but you should confirm internal mounting dimensions before purchase.

Does it supply PCIe GPU power connectors?
The listed connectors focus on SATA and Molex with a 20+4 motherboard lead; systems needing dedicated PCIe power should verify the supply provides the required adapters or choose a different model.

Is the 350W rating enough for a small gaming build?
350W can support low to mid-range GPUs and modest CPUs in compact builds, but high-end graphics cards typically need more headroom and dedicated PCIe power connectors.
