350-450W Roundup: 11 Cheap PSUs
by Martin Kaffei on July 3, 2012 1:30 PM ESTFSP OEM 400W APN and GHN -1
FSP doesn't sell these OEM versions directly in the market. Instead, they find their way through various distributors and e-tailers to end-users. They come without any packaging because the companies want to keep this extra strictly to their retail version of the product. Therefore customers get a 2-year warranty. With 120W the 3.3V and 5V rails are rated somewhat lower than we're used to, but there's nothing to worry about since modern systems don't place a huge load on these rails anymore. The GHN model has no rating on 12V, the other one delivers 336W. FSP provides a low number of connectors for both products, but they are always able to customize the configuration e.g. by adding a 4+4-pin CPU connector for an OEM/ODM customer.
This Yate-Loon fan with the model number D12SH-12 and 120mm diameter uses sleeve bearings and seven fan blades. The maximum speed is 2200rpm at +12V. The subjective loudness of the fan (and the electronics of course) will be investigated on the following page.

FSP400-60APN (230V version)
The internal layout consists of three large heatsinks. Both main caps are made by CapXon and rated at 420V. It's also easy to spot the secondary capacitors and their respective manufacturers. FSP uses different suppliers for these PSUs, a few from Teapo and some from CapXon, both of which we have seen many times lately. Since the basic designs are several years old now, we didn't expect to find anything extraordinary within the design. However, both PSUs are still sold today and you can expect good quality from PSUs that use it.

These are all elitist power supplies, not you get what you pay for power supplies.Try to find 6 pin + 6+2 pin on a 450W anywhere... they are RARE.
This is NOT the cheap power supply review - this is the name brand poular low wattage PS review.

Sorry, but were you looking for a review of, say, a PowMax power supply?? Not sure why you refer (twice, in two posts) to these power supplies as "elitist.Trust me, you don't need to make $100K/year salary to own these. Especially the Corsairs, which are regularly on sale for <$20, after mail in rebate.

I just said why, but you're "not sure" why, probably the "not sure" from the movie Idiocracy.Black1969ta - Saturday, July 14, 2012 - link

Don't ever mention PowMax in my presence ever again, speak not that word.zero2dash - Tuesday, July 3, 2012 - link
Very surprised to see the VP-450 not make the list of candidates.Between what you have here, I've used both the Corsair CX line and the Rosewill Green line. After a disappointment with the CX and coil whine, it was replaced with a Rosewill RG and I couldn't be happier.
Bottom of the barrel, me personally I'd go with either the RG or now the Antec VP-450.
I'm not spending $50 on a <500w PSU, sorry. You can get a decent 500-600w, sometimes having to wait on a rebate or a coupon code but nonetheless - Antec NeoEco, Antec HCG, even a Corsair TX2, for not much more than that.

Speaking of prices. The Raider is not available yet and the going price will be much lower than the MSRP.Antec didn't reply to my email and I wasn't able to get the US version in Germany. Anyway, I will try to get cheap Antec PSUs next time. Thank you for your comment.

That's because you're a moron. Just because it supplies lower wattage does not mean that it is any less important or valuable than an 800w power supply. Voltage regulation is pretty simple, getting no ripple and getting good efficiency is a bit harder. You pay for quality, not for wattage. If you want junk, then buy junk. This was for people who are serious about their PCs and want them to work well and last for awhile.Lonyo - Tuesday, July 3, 2012 - link
While this is a nice article on low(er) power PSUs, would it be possible to see some sort of real world enthusiast article which focuses on NAS/HTPC boxes and power?For instance, there's a Zotac Atom DTX board with 6 SATA connectors and two PCIe slots (x1 and x16 I think). Theoretically you could have 14+ HDDs hooked up (killer NAS for the motherboard form factor).
Something looking at the power of a NAS or HTPC with regards to PSUs would be nice. A 70% efficient 400w PSU would consume a lot more (relative) power on a low wattage box than something like a DC power supply with adapter (from experience), since they can get closer to 95% I believe in lower power situations.
It would also be nice to see peak (boot) power for such a HDD loaded system in terms of what sort of PSU is required to boot the thing without staggered spinup.
I personally made a G620T system with a 250w mATX PSU, which I swapped out for a PicoPSU, and dropped power use from about 35w IIRC, to 25w, which is a lot in % terms, although in absolutes it's not all that significant.
Just a thought for an article if there is the desire. I definitely am interested in low power HTPC and NAS boxes (considering building a NAS box with the above mentioned Zotac DTX board in the coming months).

I'm able to review all PSUs with AC input and DC output.SFX, TFX PSUs, Picos in combination with laptop adapters.
How about some 300W SFX units and 90W adapters? Most PicoPSU are very good but the adapter is usually a bit of a problem. Nobody takes a look inside. Quite often the quality is abysmal .
