This article covers 玄人志向 電源ユニット 600W SFX 電源 80 PLUS ゴールド PC電源 フルプラグイン フラットケーブル KRPW-SXP600W/90+.

Overview

Choosing a power supply for a small form factor build often means balancing size constraints against output capacity. The Kurotoshikou KRPW-SXP600W/90+ addresses this by offering 600W in the compact SFX form factor while carrying 80 PLUS GOLD certification. With a claimed conversion efficiency of 90%, this unit suits users who want both energy savings and reliable performance.
The power supply features a single +12V rail design capable of delivering a combined 600W (50A). All cables are fully modular and flat, making cable management easier in tight SFX cases. The ATX/EPS 12V connector supports 4+4 pin configurations, providing flexibility for modern motherboards.
In the market, this unit sits in the entry-to-mid tier for small form factor power supplies. It offers 80 PLUS GOLD certification at a relatively accessible price point, making it an attractive option for budget-conscious builders.

Compatibility Guide

This power supply uses the SFX form factor, making it ideal for compact cases that support this standard. If you plan to install it in a standard ATX case, you will likely need a mounting bracket adapter. Always check your case specifications before purchasing.
The ATX/EPS 12V connector supports 4+4 pin configurations, which matches the 8-pin EPS connector found on most modern motherboards. However, high-end CPUs may require additional auxiliary power connectors depending on the motherboard design.
The single +12V rail design allows the full 600W output to be directed where needed, which helps stabilize power delivery to the CPU and GPU. Still, since total capacity is 600W, it is essential to calculate the combined power draw of your components beforehand.

Its market position is entry-to-mid tier. The combination of 80 PLUS GOLD certification, fully modular design, and flat cables makes it a practical choice for builders who prioritize ease of installation without breaking the bank.

Best Use Cases

  • Builders creating a compact small form factor PC. The SFX size fits neatly into mini-ITX cases, and the fully modular flat cables simplify routing in tight spaces. If you only have an ATX case, you will need an adapter bracket, so check compatibility first.
  • Users who value energy efficiency. The 80 PLUS GOLD rating means higher conversion efficiency, which can help reduce electricity costs over time. However, the 600W capacity may not be enough for a high-end configuration, so verify your components' power requirements.
  • Gamers assembling a mid-range gaming rig. The single +12V rail provides stable power delivery to the GPU. For the latest high-end graphics cards, though, a larger capacity unit would be a safer choice.

Things to Consider

With a 600W capacity, this unit may fall short for builds pairing a high-end CPU with a flagship GPU. Modern high-end graphics cards draw significant power, so calculating total system draw in advance is critical.
SFX power supplies do not mount directly into ATX cases without an adapter bracket. Additionally, the flat cables, while easy to manage, may be shorter than standard round cables, which could be an issue in larger cases where components are farther apart.
While 80 PLUS GOLD certification indicates good efficiency, real-world power consumption varies with usage patterns. The unit performs well under typical loads, but consider your specific workload before committing.

FAQ

Q: Can this power supply be installed in an ATX case?
A: Since it is an SFX unit, it cannot be mounted directly in an ATX case. You can use an ATX-to-SFX adapter bracket, but make sure your case has enough clearance for the installation.
Q: What kind of system can a 600W unit support?
A: It is sufficient for a mid-range CPU and GPU combination. For a high-end CPU paired with a flagship GPU, the power draw may exceed 600W, so it is safer to choose a higher-capacity unit in that scenario.
Q: What are the benefits of a fully modular design?
A: You only connect the cables you need, which keeps the inside of the case tidy and improves airflow. This is especially helpful in small form factor builds where space is limited.
