350-450W Roundup: 11 Cheap PSUs
by Martin Kaffei on July 3, 2012 1:30 PM ESTSinan Power VP-430 430W
Sinan Power is a brand most of our readers likely have not encountered. The company behind (Inter-Tech) is in Germany, where their largest customer base is located. Inter-Tech would've never thought about sending us a unit like the VP-430, which is why we got this sample from Amazon. It comes with passive PFC (no universal AC input) and a red fan. The package includes a power cord for the European power grid, four screws, some cable ties, and a manual.
We assume Yate Loon makes the fan, one of the largest companies. The 120mm fan needs fewer amps than the other fans in this roundup and it has seven cheap fan blades. Definitely a low-quality product.

Connector type (length) |
Main | 1x 24-pin (40cm) fixed |
| ATX12V/EPS12V | 1x 4+4-pin (40cm) fixed | |
| PCIe | - | |
| Peripheral | 3x SATA (ca. 40, 55, 70cm) fixed | |
| 3x HDD, 1x FDD (ca. 40, 55, 70, 85cm) fixed | ||
The internals consist of thin heatsinks, a small transformer, and a big and noisy PFC-choke under the fan. The undersized bridge rectifier has no heatsink. There are a few components in the EMI filtering stage, but all the other parts are low-end. It doesn't look like 430W. Inter-Tech (we couldn't detect the real manufacturer) implemented a forward converter with the cheapest output caps and magnetic cores available.

What, no Cooler Master GX 450W Bronze? I CALL SHENANIGANS SIRS! A recount must be done.nubie - Friday, July 6, 2012 - link
I still love my PC Power and Cooling Silencer 470, from before they were bought up by (forget right now).Of course at over $100 it really needs to be worth it, but I have seen some on the 'Bay for $30 or so.
Too bad that PC Power didn't have a lower power supply in this test, I would have liked to see how they measure up.

I would even go so far as to say 1 KW power supplies aren't needed for most configurations. Running a Core i7 2600k, 16 GB RAM, 6 Hard Drives/SSDs (2x2TB WD Blacks, 2x1TB WD blacks, 1x1 TB Seagate, and 1xSSD 256 GB Force GT) as well as a radeon 6970. under load i pull 400 watts from a 650 watt PS. A bit more than the review mentions, but most people would swear they need a 1 KW ps for this setup.veri745 - Monday, July 9, 2012 - link
I, for one, would really appreciate some more comparison charts with all of the PSU's stacked up against eachother. You don't need every data point but a summary of at least idle and load, like maybe 50W and 400W, or 20% and 100%, would be much appreciated.Something so I don't have to flip through 9 pages to compare ripple, efficiency, noise, and PFC

Again a review by Mr. Kaffei.And again you didn't give any information about the size of your reviewed psu's.
In my view you did not do your homework. You omitted basic facts by not listing the physical dimensions of your reviewed objects. Anandtech tries to keep up a nearly scientific approach to their other reviews.
Would you omit the measures if reviewing a computer case? A smartphone? A NAS-Box? A car? A TV?
I brought this point up in several comments, alas to no avail.
I think you're shooting yourself in the knee.
Switch to german:
Wenn grundlegende Dinge wie Maße fehlen, wie vertrauenswürdig ist das ganze Werk? Wissenschaftliche Arbeit fängt bei der Beschreibung der Testobjekte an.
Wenn also die Grundlagen wissenschaftlicher Methodik verletzt werden, dann stelle ich fest, dass Anandtech die sich selbst auferlegte "professionelle Arbeitsweise" nicht einhält. Sicher ist das ein wenig Haarspalterei, werden einige sagen. Meine Einstellung: Macht es richtig oder gar nicht. Sonst droht Euer Niveau auf das der PC-Welt zurück zu fallen.

Dein Niveau (wenn man das noch so nennen kann) ist wohl schon auf unter PC-Welt gerutscht. So richtung Computerbild..zoblace - Tuesday, November 24, 2015 - link
http://www.plugloadsolutions.com/psu_reports/THERM.......on that page they tested Thermaltake Smart 430 and it acheived 80+ Bronze eff. no problem....
after that could we trust online tests at all....
