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.

I have bought two of these on sale from newegg for about $17 after $20 rebate. For $17 these are great power supplies.Martin Kaffei - Tuesday, July 3, 2012 - link
Corsair is always a good choice. Enjoy!esteinbr - Tuesday, July 3, 2012 - link
I agree. I purchased one of these on a similar deal at NewEgg. They ended up sending the 600w version of the PS so I got an even better deal on it but it's been a good inexpensive power supply. I do agree that it definitely isn't silent when the fan really spins up but it's not horrible either.Newegg happens to have this PS for 25$ after 20$ mail in rebate right now.

You got a competent 600W PSU for 17 bucks? You lucky SoB!I hope it found a good home in a nice machine.

I've had a Corsair HX 620 for about 6 years now and it has NEVER skipped a beat, "only" got 1 year left on the warranty, I've recently relegated it to another machine and grabbed a Corsair HX 850.The thing with Corsair PSU's though is that you always have peace of mind as all the PSU's they offer are good.

None of these power supplies in the article are CHEAP - save perhaps the one Sinan that almost nobody likely recognizes.These PS are low wattage near top of the line PS.
I'm not certain how the anand reviewer got that so wrong.
Whatever - it's one word but still... it's the concept, and being correct about what is spewing forth that counts.
These are EXPENSIVE power supplies.
I can show the never joe blows here some cheap power supplies - or the article writer - since the elitist smell of self aggrandization is all about...
I can't make it on 100K a year either...

uh... pipe down over there, guy. the most expensive psu is 55 dollars. most are around 30-40. what's cheap? 10 bucks? if you need a 10 dollar psu maybe you should reconsider your choice of hobbies.JonnyDough - Wednesday, July 11, 2012 - link
Totally agree. Tom's wouldn't recommend low quality (cheap!) PSU's for two very good reasons:For one, you save money by spending more, especially if you leave your PC on all the time. Better efficiency at idle means you pollute less, and spend less money on energy.
Secondly, if your PSU dies, your motherboard can go too. Who wants to waste money and have the hassle of that? Buy quality. At least if your motherboard perishes it probably isn't your fault (as long as you pay attention to ESD. Also, although you can buy better grade motherboards too by doing your research, but you will still get the one that dies the second day you use it now and then).
If you want to buy an exploding toaster to power your PC have at it. That's one less ignorant poster online.

You get what you pay for. I bought two of the V2 units - both exhibited coil whine across multiple builds and one failed to run reliably (standby power issues.) One I gave away and one is sitting on my parts shelf. It's anecdotal evidence but still enough to make me avoid them.Antec's EarthWatts 380D has been my default choice for awhile now, but I'll have to give some of these a shot.

I don't think "you get what you pay for" always applies, because I bought a Seasonic X650 gold a while back, which is a fairly expensive and highly rated unit, and I get coil whine. It happens.
