I bought a Corsair TX650 v.2, which turned out to be DOA. Reading the reviews on Newegg, I am astounded how many have had this experience with this model and other PSU's from different makers.

With what brand will I have the most chance of getting a product that works?

Your experience is just one of those things. Corsair is a good brad and I believe the TXV2 series uses a Seasonic design. If you want to change brands I would say look at Seasonic and Antec as possible alts. XFX Pro650 is another good one in this size. In fact it is using the same design components as the Corsair and may be bought a bit cheaper.

As much as the power (Watts) requirement matters, the current requirement, measured in Amps is as important if not even more important. This is especially true if you have a or several dedicated video card(s). As a general rule of thumb, you’re aiming for the highest number on the 12V line.Power Supplies that are certified 80 PLUS have been independently tested for their efficiency. Now, there are 4 different 80 PLUS certifications, depending on how efficient the power supply is:

80 PLUS: The power supply is at least 80% efficient at 20%,50% and 100% load
80 PLUS Bronze: The power is at least 82% efficient at 20% and 100% and 85% efficient at 50% load.
80 PLUS Silver: The power is at least 85% efficient at 20% and 100% and 88% efficient at 50% load.
80 PLUS Gold: The power is at least 87% efficient at 20% and 100% and 90% efficient at 50% load.

The 80 PLUS and higher certifications are the way to go when you are looking for an efficient power supply.

Do not trust specifications such as “Efficiency: 80% to 85% Efficiency Typical” that are not 80PLUS certified. 80 PLUS is an independent standard test. No 80 PLUS and “Efficiency: 80% to 85% Efficiency Typical” means that it is 80% to 85% efficient, according to the manufacturer that is, using their own in-house test, which may or may not so much represent real efficiency.Brand name doesn't really matter since almost all have made bad psu at one time or another aside from seasonic imho.Hope this helps bud and sorry to hear your psu died on you anyway.best of luck!

KingWin All reviews and testing of Kingwin suggests they are a good buy. Hardly ever the cheapest but never the most expensive, its a good alternative to bigger names.

All Models are made by Super Flower as for Delta there Excellent ;)

Delta doesn't have a retail brand. They're an OEM used by companies that sell PSUs like Antec, ASUS and Chieftec.

Delta are also the OEM for many PSUs used in Dell and HP PCs.

As for Kingwin all of their power supply models are made by Super Flower. The Absolute Platinum Series, Lazer Platinum Series, Stryker Fanless and some of the Lazer Gold models are highly rated by reputable review sites.

Super Flower is also the OEM for other PSU brands like Akasa's Freedom Power series, AXP/Xion, AZZA, NOX, NZXT, Rosewill, Sentey and Super Flower's own retail brand.

There will always be DOA's and defects in these mass produced products. There really isn't a "best" company as they all have defects that get through the cracks every once in a while. What matters most is what these companies do when and if you get one and most of the well known brands will make sure the problem are corrected.

Delta, Seasonic, Super Flower are usually the solid ones as stated above.

CM, corsair and seasonic,

Even the best PSU Manufacturers have cheap alternatives, such as the CM EP+ and Corsair CX series.

These tend to have fewer features, be less reliable, have smaller 12V Amperage, and more.

So a Mid-Range PSU from a reputable brand is your best bet.

Avoid PSU's with Affordable, Cheap, basic etc in there description.

Is HardwareSecrets a good review site when it comes to PSUs? They have a review of KingWin Lazer Platinum 850 W.

Yes, their reviews are rather thorough.

So far it's the only reputable review site that has tested the Kingwin Lazer Platinum Series 850W (LZP-850).

A bit off topic: can you add additional SATA power connections to a modular PSU? (That review notes that the the KingWIng LZP-850 has only 8 SATA connections, which could be limiting in some situations.)

Kingwin's own webpage says the LZP-850 has 5-pin SATA Connector X 12.

That would indicate it is packaged with three modular SATA cables with each cable having four SATA power connectors on them.

You can always contact Kingwin for confirmation.

Thanks. The Newegg pages also says 12 SATA connectors.

The HardwareSecrets review also said that the KingWin lacks an MOV (Metal-Oxide Varistor) at the first stage, which is supposed to deal with spikes from the power line. They don't say any more about it. Is that a real issue?

Most people plug their PC into a surge protected power bar or UPS that has MOVs.

If you're not planning on using a surge protected power bar or UPS then take into account the missing MOV.

There are German brands like AmacroX headquartered in Augsburg, Germany but all of their PSUs are made by FSP Group.

There is be quiet!, also a German company, with the majority of their models made by FSP Group and a few other models made by Seasonic and HEC/Compucase.

LC-Power is a German company based in Korschenbroich. The major OEM is Great Wall with Andyson, CWT and Huntkey as minor OEMs.

NesteQ is another German company. Their ASM Xzero Series models are all made by Enhance Electronics and all of their E2CS X-Strike Series models are made by Sirtec.

Rasurbo is also a German brand with all of their PSUs made by HEC/Compucase.

Sharkoon has its headquarters in Germany. Their PSUs are made by CWT, Enhance Electronics and FSP Group.

SilverPower's parent company has its headquarters in Ahrensburg near Hamburg, Germany. Over 75% of their models are made by Seasonic with the rest made by Solytech.

Tagan's parent company (i.e. the same one as SilverPower's) has its headquarters in Ahrensburg near Hamburg, Germany. Topower is their main OEM with Impervio, Enhance Electronics and Solytech as the minor OEMs.

Xigmatek is also German. HEC/Compucase is their major OEM. CWT, Sirtec and Solytech are their minor OEMs.

None of the OEMs, mentioned above, are German so there are no Made in Germany PSUs.
