350-450W Roundup: 11 Cheap PSUs
by Martin Kaffei on July 3, 2012 1:30 PM ESTThermaltake Smart SP-430P 430W
Thermaltake is one of many companies with PSUs made by HEC. Inside the box are power supply, a small manual, screws, and a power cable. The 3.3V and 5V rails in the 430W unit are rated at 15A and 24A. The model has 34A on 12V which is quite much for a PSU without DC-to-DC. Features of the product include the 80Plus certificate and a 3 year warranty.
Thermaltake relies on its "own" fan for cooling, with the model number TT-1225A. This one has seven fan blades and is based on a common sleeve bearing. We didn't find any information about the RPM rating but we assume Young Lin built this fan as they are a large vendor and HEC uses them steadily.

There are three heatsinks and and typical components for a HEC power supply. The mainboard consists of epoxy resin and laminated paper. The same is ture for the small PCB with the PWM/PFC control. All capacitors are made by Teapo so the main cap is not a Japanse one. For +3.3V and +5V regulation this PSU uses a kind of "magamp" regulator like most PSUs do. The EMI filtering includes all the important components.

Here's some good ones to look at in 350W-450W range:Seasonic X-400 Fanless
Seasonic S12II-380
Silentmaxx Fanless 400W MX460-PFL01
Nexus Value 430
Seasonic M12II-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
Kingwin STR-500

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 chamberCheck 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-350ETSupposedly 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.
