Thermaltake Litepower GEN2 450W PSU vs ATX 24Pin Female to 24pin Male 90 Degree Power Adapter Mainboard Motherboard for

What each product is designed for

The Thermaltake Litepower GEN2 450W PSU is a full power supply unit designed to deliver stable, reliable energy to a desktop computer’s core components. It supports the ATX 12V V2.3 and EPS 12V standards, making it compatible with modern desktop hardware. In contrast, the JSER ATX 24Pin Female to 24pin Male 90 Degree Power Adapter is not a power supply at all—it’s a simple cable converter that changes the direction of an existing 24-pin power connection. While the PSU powers the entire system, the adapter only alters the physical orientation of an existing cable.

The PSU is built for systems requiring a dedicated, efficient power source with over voltage, over power, and short-circuit protection. The adapter, on the other hand, addresses a specific installation issue: helping fit a power cable into tight chassis spaces by rotating its angle from vertical to horizontal. The PSU serves as a foundational component; the adapter is a niche fix for spatial constraints in compact builds.

Price comparison

The Thermaltake Litepower GEN2 450W PSU is priced at A$49.00, while the JSER 90-degree adapter costs A$14.23. This makes the adapter about 71% cheaper than the PSU. The price difference reflects their entirely different roles: one is a complete power delivery system, the other a minor accessory. For users seeking a new power solution, the PSU is a significant investment, but for those already owning a PSU and facing space issues, the adapter offers a cost-effective workaround. The adapter’s low price means it can be added without impacting the overall build budget significantly.

Compatibility and technical specifications

The Thermaltake Litepower GEN2 450W PSU is designed to support the ATX 12V V2.3 and EPS 12V standards, ensuring compatibility with current desktop hardware. It features a high amperage single +12V rail, which helps maintain stability under load. The PSUs’ inclusion of over voltage, over power, and short-circuit protection adds reliability for long-term use. In contrast, the JSER adapter has no internal electronics or regulation—it simply reroutes the physical connection between two 24-pin connectors. It does not alter electrical characteristics or provide any form of protection. Its sole function is to change the direction of the cable, meaning it has no impact on power delivery quality or system stability.

Build quality and durability

The Thermaltake PSU includes an ultra-quiet 120mm cooling fan that provides excellent airflow, contributing to thermal management and reduced noise during operation. Its construction is designed for continuous use in desktop systems, with protections against electrical faults. The JSER adapter, however, is made of basic plastic and metal connectors without any cooling or safety mechanisms. It relies entirely on the integrity of the original PSU and motherboard cables. Since it has no internal circuitry or heat dissipation features, its durability depends solely on the quality of the materials used in the connectors and housing. There is no indication of surge protection or long-term reliability testing in its description.

Use case suitability

The Thermaltake Litepower GEN2 450W PSU is ideal for basic desktop systems with lower power consumption where efficiency, reliability, and quiet operation are priorities. It is Haswell ready and includes an extra long EPS/ATX 12V 4+4pin CPU cable, making it suitable for full tower chassis. The JSER adapter is intended for users who need to reposition a 24-pin power cable due to limited height in their chassis. It enables a vertical-to-horizontal installation shift, solving space issues in compact cases. However, it cannot be used as a replacement for a PSU or to add power capacity—only to adjust the cable’s orientation.

Bestseller ranking and market presence

The Thermaltake Litepower GEN2 450W PSU holds a bestseller rank of 7 within its category, indicating strong consumer demand and trust in its performance. This high ranking suggests it is a well-regarded choice among users building or upgrading standard desktop systems. The JSER adapter also holds a bestseller rank of 9, which is impressive for a small accessory. This shows that many users face similar challenges with cable routing in tight chassis setups. Both products enjoy solid visibility in the marketplace, though the PSU's higher rank reflects broader appeal as a core component.

Installation and usability

Installing the Thermaltake PSU requires disconnecting the old power supply, routing the new unit into the case, and connecting multiple cables—including the main 24-pin and CPU power connectors. It is a full system-level task that demands careful planning and safety precautions. The JSER adapter, meanwhile, is plug-and-play: it connects directly between the PSU’s 24-pin output and the motherboard’s input. No tools or disassembly are needed. Its 90-degree design allows the cable to lie flat, reducing strain and improving airflow in confined spaces. However, it does not offer any additional functionality beyond reorientation.

Which should you buy?

If you're building or upgrading a desktop system and need a reliable, efficient power source, the Thermaltake Litepower GEN2 450W PSU is the clear choice. At A$49.00, it delivers full power delivery with built-in safety features, a quiet fan, and compatibility with modern hardware. If you already have a working PSU but are struggling with cable clearance in a compact chassis, the JSER ATX 24Pin 90-degree adapter at A$14.23 offers a simple, affordable fix. The adapter is not a substitute for a PSU—it’s a directional tool. Therefore, choose the Thermaltake PSU if you need power; opt for the JSER adapter only if you’re solving a cable routing issue.
