見た目にこだわらないコスパ重視ならこれで良いね

見た目にこだわらないコスパ重視ならこれで良いね
シャシー色はPCケースがブラック／ホワイトどちらでも何となく合ってしまう無難なシルバーです。またケーブルも必要な分だけ挿す単色のフラットケーブルではなく、直接生えている色分け式で等間隔に結束バンドで束ねてあります。ケーブルは長めでミニタワーなら余裕の配線です。 使うケースがホワイトなのでスタンダード、良く言えば「カラフルなケーブル」はひどく目立ちますので白いケーブルカバーをしましたが、昨今のケースは配線がほぼ裏側を通るので最小で済みます。また、使わないケーブルも柔らかめなので束ねて目立たない位置に収めるのも楽なはずです。 PCの仕様はRyzen5 5500GTで外部グラボは使わない、ストレージはM.2SSD 512GBのみのミニマム構成なので400Wで間に合いますが在庫がないみたいだったので500Wとしましたが価格差が微妙で、400Wか600Wがコスパとしては良いと思います。

    5.0 out of 5 stars コスパの良い電源ユニットを求めている方におすすめ
    Reviewed in Japan on August 14, 2025
    Style: 1. 600W long cable modelVerified Purchase
    玄人志向の600W電源ユニットは派手さこそないもののPCの心臓部としての役割をしっかり果たしてくれる“職人肌”の一品です。
    安定性は中〜上級クラスのグラボ（RTX 3060など）でも安定動作。
    電圧のブレも少なく長時間のゲームや動画編集でも安心。
    静音性はアイドル時はほぼ無音。
    負荷時でも風切り音が気にならない程度で静音PC構築にも向いています。
    発熱は筐体内の温度上昇は控えめ。
    エアフローがしっかりしていれば夏場でも問題なし。
    高級感や最新技術を求める人には物足りないかもしれませんが安定性・静音性・コストの三拍子が揃った玄人志向らしい製品です。
    自作PCのベースとして安心して選べる一台です。

    ５月２１日昼頃の発注で、２２日の朝に届きました。
    サイズと価格と電力が丁度良い品で、ロープロファイルのケースにDVDプレーヤー迄組み込んでピッタリです。
    ケース内の空間は余り余裕のある作りではありませんが、冷却ファンが全力で回る様な事も無いので良いかと。
    後の気がかりは耐久性ですね。　１日１０時間程度の稼働なので、５年位は使いたいなぁ。

    3.0 out of 5 stars チョット音が。。。
    Reviewed in Japan on August 14, 2025
    Style: 3. 400W long cable modelVerified Purchase
    いままで　電源は信頼のおける物を使用してきました
    玄人さんも多々使用してきました（電源以外）が
    チョット音が大きいです
    古い扇風機のような（文字では表現が難しいですが）フンゴーンカーカカカホリポレレレみたいな笑
    電源取付前にしている（現在進行形）ので　ケースに入れるのが怖いです（静かになる可能性もありますが、共振なども怖い）
    ファンのアンバランスによる軸の音っぽいですが　もしかしたら内部の導風板（透明プラ板）かもです
    今回は初の低スペ低予算でしたので　購入しましたが　ファンだけ変えようか考え中です
    よくある　ファー音ではないので　気になりました
    電源としては　まだわかりませんが　レビューになります

    This power supply is a beast! I’ve been using one just like it for over 10 years, and it’s never let me down. That’s why I decided to buy another for an older PC I revived to run Pop!_OS. It still works perfectly, with stability and efficiency. For anyone looking for a reliable and durable power supply, this is a solid choice. Very satisfied!

    ゲーム等しないので電力消費の多いグラフィックカードは使わず、
    500W程度の商品を探して購入しました。
    今のところ普通に使えています。音も静かです。
    PCケースは古いものを流用したのでサイズが合うか少し不安でしたが、無事に取り付けできました。

    5.0 out of 5 stars コスパ的に安くて、ケーブル種類も十分でいい製品です。
    Reviewed in Japan on September 5, 2025
    Style: 1. 600W long cable modelVerified Purchase
    使っていたメーカー製のパソコンが壊れたので、初めての自作パソコンに、こちらの電源ユニットを選びました。用途的にゲーム性重視ではなく、普通生活でつかうWEB閲覧、オフィス事務ソフトが目的だったので、コスパ的に安くて安定性のあるメーカーなので、600Wで十分だと判断し購入して初めての自作パソコンで使用しました。基本的なケーブルは余裕に付いてるので、十分納得いく製品でした。ゲーム性重視の方は、もっと上の750～800Wの電源でGPUの補助電源の電力量とケーブルの形状と本数を確認してから、電源ユニットの購入を慎重に検討した方がいいと思います。コスパ的に安くて、余裕のあるＳＡＴＡ等ケーブルがついていたので納得いく製品でした。
