Review Update : Revolution at Your Doorstep: New Power Supply Units from Antec, Enermax and Seasonic @ XBitlabs @ First Page

Summary for Antec SG-850W

The Antec Signature leaves a very nice impression with its excellent quality of manufacture, splendid electrical parameters, sufficient selection of cables and connectors, and with such a quiet operation at low loads that could hardly be expected from a PSU with only one 80mm fan. No wonder that Antec considers the Signature series the best of its product range even though the company offers PSUs with higher wattage ratings.

Perhaps the only downside of this PSU is its high price. But you won’t be disappointed if you pay it.

Summary for Enermax Revolution 85+ 850W

I won’t say if it is revolution or evolution, but Enermax’s engineers have indeed come up with something new and original from a technical standpoint. This PSU is original not only with its exterior but also with its interior design. The capabilities of the Revolution 85+ may seem even redundant for today – the number of unused connectors for detachable cables is a clear indication of that. However, people at Enermax stress the point that they have tried to create a platform not only for today but also for near future, stuffing it with everything best that modern electronics can offer. And they seem to have succeeded.

Besides the moral satisfaction of owning one of the most technically sophisticated power supplies, the Enermax Revolution 85+ offers you good quality of manufacture, excellent electric parameters, a rich selection of cables and connectors, and quiet operation throughout the entire load range, up to the maximum 850W.

As you may have guessed, the biggest downside of this product is its price. The recommended price is $309 or €229 taxes excluded.

Summary for Seasonic M12D 850W

The Seasonic product perhaps does not look as impressive as the Revolution 85+ but in practical terms it is not inferior to its opponents from Enermax and Antec. Yes, one of them is technically perfect, but what’s the purpose of that perfection if the output parameters are almost the same?

When it comes to the effective parameters, the M12D can only be criticized that its output voltages are not very stable. There is no other fault I can find with it. It features low voltage ripple, a very high efficiency, a gorgeous selection of cables, and quiet operation at low and medium loads. Thus, it will make a perfect power supply for a home computer.

The recommended price of this PSU is $299.

Review Update - BFG ES-800 @ Hardwaresecrets @ First Page

Conclusions

BFG ES-800 isn’t the best product available in the market, but it is also not the worse. If you decide to buy this product, you need to make sure that your serial number starts with 0835 or greater, otherwise you will have a huge electrical noise problem when pulling less than 800 W from this unit. Also, if you decide to buy it, you must register within 30 days of buying it, otherwise you will lose the lifetime warranty provided by BFG and get only a louse 1-year warranty.

If you have a unit with production batch lower than 0835 (most likely 0804), contact BFG and ask them to replace your unit, because your model is completely flawed.

But even the “fixed” version of this power supply presents high noise levels when delivering 800 W. This shows how having only Japanese capacitors may mean nothing.

BFG ES-800 presents a high efficiency between 84% and 85% if you pull up to 60% of its labeled capacity (i.e. up to 480 W). Pulling 80% from its maximum wattage efficiency dropped to 82.4%, still above 80%. At full load, however, efficiency dropped to 79.1%.

Having so many “ifs” and costing USD 190, we can’t recommend this power supply, even though if you bought one from the right batch you should not face more problems, as most people won’t pull even close to 800 W. Currently there are several other better options on the market (e.g. Corsair HX850W costs the same thing, doesn’t have the same issues and presents a far higher efficiency).

Summary

The Mach 1 does several things very well. It has the voltage regulation, the efficiency, and the power to be a good contender in the marketplace. It's just too bad that the ripple bug had to come up and cut the legs off the poor thing. All the same, you could do worse than this unit. No recommendation this time, but I'm hoping Kingwin can get the ripple tamed for the next one. This platform's capable of a lot, and I want to see it happen.

The Good:

* efficient
* above average overshoot transient performance
* PCI-E connectors get 70A if needed

The Bad:

* bling factor is a bit over the top

The Mediocre:

* ripple issues

Review Update : Rocketfish 550 W @ Hardwaresecrets @ First Page

Conclusions
Hardware Secrets Golden Award

We must say that we were really impressed by this new Rocketfish power supply. Although it is not really a 550 W unit, it is a decent 500 W power supply and available for a not so bad price (USD 90 on any Best Buy store), which is unique, as Best Buy is certainly not know for having the best prices around. Of course it could cost less, but the advantage of this unit is that you can find it on any Best Buy and may be a good buy when you need a decent power supply over the weekend and/or can't wait for the delivery from your favorite on-line store.

Rocketfish achieved a high 85% efficiency when we pulled up to 300 W, which is more than anyone thinking of buying this unit will pull anyway.

The only drawback from this unit is only has six-pin video card connectors. One of them should be a six/eight-pin connector in order to allow you to install one very high-end video card.

For the user building a mainstream PC, this power supply is a good buy.

Be aware that Best Buy warranty is of only one year, and most brands in the US offer warranty of at least three years. This is also something you should keep in mind.

The bottom line: it passed our tests.

Review Update : Seventeam ST-750P-AF @ Hardwaresecrets @ First Page

Conclusions
Hardware Secrets Golden Award

It is good to see Seventeam finally entering the US retail market. From our experience their products are honest and present a good cost/benefit ratio for the mainstream user.


Talking specifically about ST-750P-AF, it presents high 84%-85% efficiency when you pull between 40% and 60% from its labeled capacity, i.e. between 150 W and 450 W from it. Under other loads efficiency isn’t the best in the world, but at the same time isn’t the worst.

The number of available cables is enough for the user building a high-end PC with up to two high-end video cards. If you want to install three video cards you will either need adaptors or a different product, as it provides four video card connectors and each high-end video card requires two of them to operate.

The only drawback from this power supply is the electrical noise level. Even though it was below the maximum allowed, we wanted to see noise and ripple at lower levels. Usually power supplies with high noise levels we give our Silver Award, but considering that this unit costs only USD 130 it presents an outstanding cost/benefit ratio for the user looking for an honest 750 W power supply, and that is why we are giving this unit our Golden Award seal.

We’d like to remember that internally this power supply is identical to Seventeam ST-750Z-AF and SilverStone ST75EF, so all performance considerations are also valid for these other two products.

The only feedback we need to give to Seventeam is for them to fix their website and product box and replace "Japanese capacitors" by "Japanese capacitor on primary" or similar wording, as "capacitors" lead the consumer to think that all capacitors inside the power supply are Japanese, which is not the case.

Review Update : Corsair CX400W @ Hardwaresecrets @ First Page

Conclusions
Hardware Secrets Golden Award

Corsair CX400W is an excellent product for the regular user that is building a PC with just one video card. It provides enough cables and they are long, allowing you to easily install this power supply inside a full tower case.

Efficiency was great for an entry-level product, peaking almost 84%. Voltages were very close to their nominal values and ripple and noise were practically non-existent.

Internally Corsair CX400W is similar to Corsair VX450W, Antec EarthWatts 500 W and Arctic Cooling Fusion 550RF, but using less power transistors on the primary.

Costing only USD 50, it provides an outstanding cost/benefit ratio. If you are building a mainstream PC and are not thinking of installing a very high-end video card you can buy this power supply with your eyes closed.

Review Update : Enermax Liberty Eco 620W @ [H]OCP @ First Page

The Bottom Line

The Enermax Liberty Eco 620W is another very competent product from Enermax that should work out well for the majority of users power needs. While being slotted in slightly below the MODU82+ this unit generally compares favorably to that unit (though the dual 12v rails here is not the best it could be) and on the performance side of things only trails it in efficiency, and voltage regulation. Otherwise, the Liberty Eco absolutely beats the MODU82+ in Transient Load Testing and DC Output Quality while throwing up a nice tie for noise output. As such, any user considering the MODU82+ should also consider the Liberty Eco and their price points as the Liberty Eco 620W can be had for just $129 which is an OK deal for a good unit. However, the Enermax ECO 80+ is currently at Newegg for $100 after MIR which is simply a much better deal.

Summary

PC Power and Cooling has reason to smile, for the Silencer 910 is an excellent unit. Its regulation is up there with the very best I've tested, its ripple suppression is as good as anything else I've tested, and the overshoot transient suppression is in general the best I've ever seen. That said, it's just... not... SILENT. Especially when you get it hot and load it up. Guys, please consider the big fan approach... that myth needs to go. While you're at it, kill the modular one too. A world of awesome sales figures awaits.

The Good:

* already excellent regulation only gets tighter in the hot box
* had no problem with 46 degree ambient temps
* still fairly efficient at really low loads
* excellent turn on transient suppression
* lots of connectors

The Bad:

* only two Molex caps

The Mediocre:

* it's loud. What? I said it's loud. What? IT'S LOUD! No, I didn't say it's cloudy, I said it's... oh forget it.

CATATAN : Persaingan di kelas 850W ini sungguh ramai. Hampir semua merek terkenal memiliki jagoan yang terbaik Anteq, Enermax, Seasonic, Corsair dan sekarang PCPnC.
