350-450W Roundup: 11 Cheap PSUs
by Martin Kaffei on July 3, 2012 1:30 PM ESTRasurbo RAP 350 & 450W
Rasurbo is a German brand and HEC is the OEM behind many products including the Real&Power series. HEC (or COMPUCASE) has been making power supplies and other products for quite a while now. Cougar is their well known retail brand. Today we will review the 350 and 450W version HEC built for Rasurbo. Features include 80Plus and silent operation. Both PSUs come in a dark green/black housing with just 14 cm depth. Two 12V rails provide more than enough combined power for most graphics cards. The devices get cooled by 120mm fans and various extras such as cable ties are within the scope of supply.
Rasurbo uses a fan from Young Lin with the model number DFS122512M. M stands for "medium rotations per minute" (2000RPM). This common sleeve ball bearing type fan has a peak power consumption of 2.8W and has seven fan blades.

Looking inside of this unit shows a similar heatsink design to what we saw in the FSP units. This time they look less massive. Most of the capacitors are made by Teapo; the primary one comes from Capxon. EMI filtering consists of two common mode chokes, four Y-caps, and two X-caps. An IC on the secondary side features safety functions such as OCP and short circuit protection. There is a lot of glue inside but it's better to fix heavy components rather than reducing safety for better looking electronics. The main transformer is somewhat small but we should mention that this is the 350W version. The larger one has a similar design with different components.

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....
