350-450W Roundup: 11 Cheap PSUsby Martin Kaffei on July 3, 2012 1:30 PM EST
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.

pvdw - Wednesday, July 4, 2012 - linkHere's some good ones to look at in 350W-450W range:
Seasonic X-400 Fanless
Silentmaxx Fanless 400W MX460-PFL01
Nexus Value 430
And just above the 450W range, but unlikely to use any more power in most systems are these good ones:
Enermax Modu/Pro87+ 500W
pvdw - Wednesday, July 4, 2012 - linkBTW, 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:
A5 - Wednesday, July 4, 2012 - linkThe 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.
knutjb - Wednesday, July 4, 2012 - linkIn 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.
pvdw - Thursday, July 5, 2012 - linkA quick search turns up this link:
The Seasonic S12II 430 for $60 shipped. Or the 380W for $54 shipped.
clarkn0va - Friday, July 6, 2012 - linkSeasonic 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?
Belard - Wednesday, July 4, 2012 - linkI'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.
piroroadkill - Wednesday, July 4, 2012 - linkWhen 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..
Arnulf - Wednesday, July 4, 2012 - linkGreat 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.
