Thermalktake PurePower 680 update

Strengths: Massive Power, fully SLI capable, two fans, very quiet, excellent outside finish, color coded sheathed cables, three year warranty, adjustable rails, fully ATX 2.01 certified

Weakness: Now surpassed by newer Thermaltake models, Various cables are too long (best suited for larger cases)

I have discontinued this review because as any tech geek knows, times change and better products are manufactured. If you are currently in need of a high end power supply then take a look at newer Thermaltake Toughpower 850, 1000 or 1200 watt models.
(My review below was last updated during May of 2006) The Purepower 680 watt power supply which was released in February,2005 is still one of the best, as of May, 2006. It has recently been surpassed by its big brother the Thermaltake Toughpower 750 watt model, which features quad +12 volt rails and a silent 140mm fan. So you may want to check out the Toughpower 750 before buying.
At any rate, the Purepower680 gives you 680 watts at 25 degrees C and about 470 watts at 60 degrees C. This is distributed over three +12 volt rails (which means you do not run into the power failures common in ATX 2.0 (pre 2005) power supplies). The Purepower 680 is cooled by two fairly quiet 80 mm fans in a push/pull configuration, and this allows for almost silent operation when inside the case. The outside finish is polished to a mirror shine and all the cables are sheathed and color coded to aid in case appearance. You also get ten 4 pin molex, one 24 pin motherboard, one 4 pin auxillary motheboard, 4 SATA, 2 floppy and most importantly two PCI Express video card power connectors (this allows you to run SLI (two video graphics cards that work in tandem)). This power supply will easily power an SLI motherboard, AMD FX-62 dual core, 4 hard drives, two optical DVD burners, X-Fi sound card, front fan controllers, two Nvidia 7900 GTX graphics cards and a water cooling pump. I do not recommend this model however, if you plan to run Quad SLI (for that you need roughly 850 watts or more to be on the safe side). The advanced tweaker can even remove the lid and tweak each individual voltage rail. And if anything ever gives out you have the three year warranty to back you up.
After researching the PC Power and Cooling SLI 510, 850 and 1000 watt, Enermax 600 and 660, OCZ GamerXStream 600 and 700, Seasonice 600 watt, Silverstone Zeus 750 and Antec TruePower 550 models it is clear that the Purepower 680, even after 16 months, comes out close to the top. If you have money to burn and dont mind loud fans, then go for the $480 PC P&C 1000 watt models (avoid the Silverstone Zeus models unless you love vacuum cleaners). If you are not going to run SLI graphics but are still a power user or enjoy quiet computing, then look at the Seasonic 600. If you have a decent setup now and plan to upgrade later and consider a small amount of fan noise (30 dba) acceptable then look to the Purepower 680, the Toughpower 750 or the new OCZ GamerXstream 700 watt (which is ATX 2.2 compliant, has four +12 volt rails and is cooled by one large 120 mm fan).
I was reticent to purchase from Thermaltake because it seems that some of their past power supplies have been very ho hum, but I think their engineers hit a home run with this model (plus the profusion of good stuff that is rolling out of Thermaltake this year indicates the company has really started to focus on quality over quantity). If you are a power user or want to run an SLI setup then the Purepower 680 or the Toughpower 750 is the fusion reactor you need, period.

ThermalTake PurePower 680W ATX12V Power Supply

Strengths: Large capacity, number of available connector cables and types, long warranty and quality.

Weakness: So far I can't think of a thing.

The other reviewer of this product did a great job of checking out all the available P/S's. I myself did a very quick job and relied on his expertise of this product. The supply has every connector you'll need, I have it connected to a 3 Raid array and a 2 Raid array along will 5 Optical drives and a 6800GT video card. It pumps out the amps and stays cool and is not noisy. I see a vendor just dropped the price $10 with free shipping, good point to buy one.

ThermalTake PurePower 680W ATX12V Power Supply

Strengths: 680w wow!!!

Weakness: none so far

was previously using a 500w Power Supply with 3 hard drive, pentium4 3.2g processor, and ati allinwonder 9800pro video card. Well I guess that was too much for the 500w PS, and it started to make loud noises and then eventually, it refused to power up. Had to disable 2 of the hard drive and the the old PS worker fine. Now that I have this 680W thermaltake I have more that enough power. Plus its around 17dBa which is really quite for such powerful wattage.

ThermalTake PurePower 680W ATX12V Power Supply

Strengths: awesome 680w gives headroom for years to come as well as the peace of mind that goes with all that

Weakness: larger than average size may complicated installation in some computer cases.

for me in helping my cousin build his own computer
i just had to make sure the psu would have adequate power for whatever power hungry components such as sli cards, and dual core cpu's
just to name 2 he may decide to throw in now as
well as the upgrades he may decide to throw in
years from now, so it's only fitting that i wanted was
a very powerful psu, and the thermaltake purepower 680 is what i got him, and regarding the weakness i stated above, well i got him the va8000 computer
case which is a full tower by thermaltake so with
that, fitting the larger than average purepower 680 psu was no problem.

Excellent Power Supply

Strengths: Quiet, 680W!

Weakness: none

Great power supply. Quiet, powerful, great price. The only one more powerful on the market right now is PC Power & Cooling's 850W. Good choice for a power user, especially if you are going to run your video cards in SLI mode.

Pushed incredibly hard, and is rock solid!

Strengths: Great Design, A++ Quality. No shortcuts were taken with this design. Many connectors, quality wiring, just a great design overall.

Weakness: Power Supply is about an inch longer than most power supplies, so it may be difficult to fit into a small case. This was not an issue for me.

Let me start out by saying that my use for this power supply is probably one of the more demanding configuations out there. I have a home file server I've built that contains 10 7200 RPM hard drives, 7 case fans, 2 3ware raid controllers + all the normal stuff (CD, Floppy, CPU etc).

I was running an Antec Truepower550 and was having stability issues after I added 2 more hard drives and the second 3ware card. Upon further investigation (And lots of frustration with random computer hangs) I found that my +5 voltage was running at about +4.5. This really surprised me. When I purchased the 550W power supply, I thought that would be all the power I would ever need. Not so. I upgraded to this 680W power supply, and my server has been rock solid ever since, with the +5 voltage running at 5.1+. This power supply has a 50A +5V rating, the highest I could find for a power supply in this price range. The Antec I had been using had a 40A +5V rating.

Aside from this power supply solving my stability issues, I am was very please with the overall construction. This unit has by far the most power connectors I've ever seen on a power supply. In addition to that, the wires themselves were thicker than most I've seen, suggesting a higher level of quality. Also, each set of wires is individually sheathed with a plastic mesh. The power supply also comes with an ATX adapter to plug into older 20pin ATX motherboards. The entire package of this power supply is TOTALLY worth the price. I hesitated spending $150 for this, but when I opened the box I instantly knew it was worth the money. This is a well designed product, that I would highly reccomend to anyone with excessive power needs.

Need more "juice"?

Strengths: 680W. Plenty of connectors. Very stable. Excellent cooling capacity.

Weakness: Fan acustics may be a concern to some people.

I needed to purchase this unit to power my dual-core 2.8ghz CPU, and 16 hard drives. You'll find an ample amount of connectors (10 molex, 4 sata, 2 floppy, and 2 6-pin Pci-Express).
It is cooled by two strong fans, which for silence enthusiats could be a small issue. I'm not sure, but it appears to be 2-speed only, depending on temperature.
It does have a 24-pin connector natively, but a 5in 24-20 pin conversion cable is included.
The finish is a dark-gray chrome, and polished. Easy to stratch.
One can guess that it's good when you lift it, it's got a good weight with all the heatsinks inside.
You may read in reviews that it's voltage is about 5-10% then most powersupplies. It's not something that you need to worry about. Your conponents should be fine (my 16 drives are happy), however it does supply better system stability a peak-times when the voltage drops due to demmand. It provides a small cussion for the response-time.
This PSU has 3 rails, which is why it can provide 680W with stability, and at a reasonable price.
Plus, Thermaltake originated in the US.
Overall a great PSU. 5-stars.

Powerful power!

Strengths: 680W should be a usable PS for years; SLI PCI-Ex connectors.

Weakness: Bigger than standard.

It's nice to have a sure reserve of power for modern systems with demanding MoBos, dual graphics cards, and multiple HDDs, fans and liquid cooling solutions. This solitary PS can handle all of that together.
It's slightly longer than the usual PS, and was a somewhat difficult fit, even into a full tower case (it required some careful maneuvering and application of force).

ThermalTake PurePower 680W ATX12V Power Supply

Strengths: High power output, automatic power factor adjustment

Weakness: Non-modular connectors

This power supply provides ample power if you need it now or later. It will not use 680 from the wall, only what is needed, thanks to active PFC. The specs have close to 97% efficiency. My only issue with this power supply is non-modular connectors. The unused connectors use a lot of space. This can be a problem depending on the size and configuration of the case.
