This article covers EVGA Power Supply 100-B1-0700-K1 700W 80 Plus ホワイト.

Overview

The EVGA 100-B1-0700-K1, also known as the EVGA 700 W1, is a 700W power supply with 80 Plus White certification. It features active PFC and six protection circuits including OVP, UVP, OCP, OPP, and OTP, ensuring stable and safe power delivery. The unit employs an intelligent auto-fan that stays nearly silent under light loads, making it a great choice for budget-conscious builders. Positioned as an entry-level PSU, it offers solid reliability for everyday office PCs and entry-level gaming rigs without breaking the bank.

Compatibility Guide

This PSU conforms to the standard ATX form factor, fitting most mid-tower cases. It includes an ATX main connector, SATA power connectors, a floppy connector, and PCIe 6+2 pin cables for graphics cards. With 700W capacity, it can comfortably power a mid-range GPU like an RTX 3060 or RX 6600 along with a mainstream CPU. However, high-end GPUs (RTX 4080 or above) or multi-GPU setups will require a higher wattage unit. Cable lengths are standard, so large full-tower cases may require careful routing. The unit is not modular, so unused cables must be tucked away.

Product Info

Released around 2020, the EVGA 700 W1 is widely available through major retailers like . Pricing hovers around ¥30,000–¥33,000 in Japan, making it a competitive option in the entry-level 700W segment. The manufacturer offers a 3-year warranty (verify with your region). Market positioning is clearly entry-level: it delivers essential protections and decent efficiency without premium features like modular cabling or high-end efficiency ratings. The active PFC and comprehensive protection suite provide peace of mind for budget builds.

Best Use Cases

First-time PC builders: If you're assembling your first desktop and want a reliable, affordable PSU, this unit is a safe choice. The protection circuits and quiet fan reduce risk and noise, letting you focus on other components. Office and home desktops: For light workloads like web browsing, document editing, and media playback, 700W is overkill but ensures headroom. The near-silent operation is a bonus for quiet environments. * Entry-level gaming PCs: Pair this with a budget GPU (RTX 3050, RX 6600) and a mid-range CPU for smooth 1080p gaming. It leaves enough power for modest upgrades later.

Things to Consider

The 80 Plus White certification means lower efficiency compared to Bronze or Gold units, which translates to higher electricity bills and more heat under sustained heavy loads. If you plan to run demanding tasks like rendering or mining, consider a higher-efficiency PSU. The 700W capacity is insufficient for top-tier GPUs (RTX 4080/4090) or multi-GPU configurations. The non-modular design can make cable management messy, especially in smaller cases. Also, the included floppy connector is obsolete for most modern builds, adding unnecessary clutter. ## FAQ
Q: Can this PSU power an RTX 3070? A: Yes, the RTX 3070 recommends a 650W PSU, so 700W is sufficient. However, for peak power spikes, a 750W unit would provide more headroom. Q: What's the difference between 80 Plus White and Bronze? A: White guarantees 80% efficiency at 20%, 50%, and 100% load. Bronze offers 82–85% efficiency, reducing heat and electricity costs. If the price difference is small, Bronze is usually a better long-term investment. Q: Are all necessary cables included? A: Yes, the unit comes with ATX, CPU 4+4 pin, PCIe 6+2 pin, SATA, and floppy cables. However, it is non-modular, so you must manage unused cables inside the case.
