    This is a great 650W PSU I purchased it back in 2019 and haven't had any issues to date. It has powered a 1080ti FE with a 2600x and currently powers a 5800x3D and a RX 6950xt XFX Black and 8 Fans on a 34" Ultrawide with no issues at all.

    5.0 out of 5 stars FAR better than I expected for the base model PSU (400W). Voltages are stable and accurate at idle or under load. A+
    Reviewed in the United States on November 14, 2017
    I'll admit I didn't have high hopes for this PSU, and was going to buy the Rosewill with a longer warranty for just $2 more, but it was going to take 5 days (with Prime--Amazon is getting a little lax in the shipping times--what happened to 2-day shipping?), so I ordered this instead since I could get it next day. I was replacing a mediocre 500W Coolmax power supply that had been in the PC, which runs 24/7, for 9 years non-stop. But it had become unstable and the MOSFETs were whistling. Luckily the ASUS motherboard shut itself down when it detected surges in the PSU 3.3v and 5v rails (not even in the 12v where it would be expected). So I had days to get it back running, and this was the quickest I could get a PSU.

    And I'm quite surprised. I never needed the 500w the old one was allegedly capable of, since this is just a PC that has operated as a media center since 2011 with just an AMD Phenom II X4 Black Edition with a basic GeForce 710 card in it and 3 spinning hard disks internally plus a bunch of USB accessories. Not massive power requirements, and 400W is more than enough.

    So on to the new PSU. First, it's the closest to spec I've ever seen in a PSU that isn't a top of the line 80PLUS Gold & Platinum certified models. Vcore obviously fluctuates since it is variable and why it's only 0.9V in the screenshot, but the 3.3V, +12V, and +5V readings are what I get from either the BIOS (so no system load) or even under load in Windows. The +5V has been between 4.97V and 5.04V (the old Coolmax was usually at 6V), while the +3.3V doesn't change but a few hundredths of a volt. The +12V, which is just a single rail compared to the dual rail of the old Coolmax, hasn't dipped below 12V at all, with it mostly sitting between 12.05-12.30V, with it fluctuating a bit more since the 12V rail gets a lot of use. The Coolmax never put out below 12.4V for the 12V rails, with it fluctuating pretty wildly between 12.4V and 13.6V depending on load.

    This thing so far has been rock stable for voltages. I was able to undervolt my CPU, RAM, and NB by a pretty significant amount compared to the setup I had. Now the CPU runs about 4°C cooler on average due to the lower and more stable voltage. And the PSU itself barely puts out any heat at all, and you can't hear the fan at all (unless you have no other fans in your case, at which point you would hear the fan. But it's very quiet even at full load.

    All in all, this base model 400N1 power supply has been amazing. If it lasts me only the 2 years of the warranty, I'd be a bit disappointed though not upset, but if it made it 5 years or more, even better.

    Still, I just can't believe how stable the voltages are and how close to spec they are. Now everything runs cooler and more efficiently. I would definitely try another EVGA power supply, even with the negative stories I've heard.

    The only downside would be that the SATA power rail doesn't have a ton of distance between the first and last connector, meaning in a tall case, it won't reach from the top optical drive down to a hard drive at the bottom. Luckily my DVDR drive has both SATA and molex on it, so it didn't ruin the day (since adapters on PSUs almost always fail catastrophically, I never use them). But if you need the SATA ports to stretch from the top of a mid-tower case to the bottom, this might get tight.

    I'm impressed overall. Never thought I'd be impressed by a base model, $30, 400W power supply, but I definitely am. Now if it doesn't fail in the first few years, it really will be my favorite PSU.
