350-450W Roundup: 11 Cheap PSUs

Some of you have suggested to review a few PSUs with 350W to 450W. Therefore we picked a collection of such units from well known and unknown manufacturers and tortured them with our overload tests. Read on to find out who delivers the best performance.

~400W is still plenty even for a midrange system, and with optimal efficiency generally coming at 50% load these power supplies should run closer to their "sweet spot" when idle as well as under load. There's still enough power on top to run a Core i7 or Phenom X6 processor and a discrete GPU.

    BTW, though I really enjoy most Anandtech articles, your PSU ones can't beat SilentPCReview. But then I can't see how you could do better without an anechoic chamber

    Check out their list of recommended supplies:

    The cheapest PSU on that list is well over $100, which is more than double the most expensive one in this article, which is about finding a good "cheap" PSU.

    I'm glad AT did this article as it should encourage a little more competition in the low-end space.

    In my experience I've had a couple low end PSUs do bad things to MBs even though they were modestly loaded. After using a number of different manufacturers all I buy are Seasonics. I get them when they are on sale.

    I have a 9 yr old 600 S-12? on its second system and the output measures the same as it did when new. Blow out the dust occasionally and it just works. Even in low end systems I don't trust inexpensive PSUs, their quality control is all but non-existent with wide variation in samples.

    You get what you pay for and I don't like buying things twice.

    A quick search turns up this link:

    http://www.amazon.com/Seasonic-ATX12V-S12II-430-BR...

    The Seasonic S12II 430 for $60 shipped. Or the 380W for $54 shipped.

    Seasonic SS-350ET

    Supposedly not as quiet as their retail offerings, but always inexpensive. I would like to see how this one holds up against similar offerings.

    Maybe AT needs a Bench section for PSUs?

    I've bought some CX models for bottom end PCs for clients...

    But I picked up two 500w models, both were defective.

    1) Defective power connector (at the motherboard)...

    2) Flutter fan noises.

    Returned them, bought Thermaltake TR2s.

    When the Corsairs first hit the scene, the HX series were all Seasonic.

    Corsair is a nice rebrander, but I go straight to Seasonic for my own system's PSU these days. I have a Seasonic X-660..

    Great article !

    I wish you could round up even more models and/or present the results in a common bench-like database (you know, like the CPU comparison etc.) where different models coudl be added over time.

    That Sinan PSU is likely made by LongYi, a small and crappy PSU manufacturer in Guangdong, China. They make knock-off, cost-down designs based on reverse-engineered FSP and similar PSUs. Reply
