The 1000W ST1000 from Silverstone provides the power you need for your most intense applications. It can continuously deliver the full 1000W at 80-87% efficiency, over dual +12V rails for balanced power distribution. The auto-switching input can handle all common voltages so all you have to do is plug it in.

The power connectors are fully modular, letting you use only the connections you need. Any extra cables go into a handy carry bag, so they’re still available when you upgrade. The cables are all sheathed to de-clutter the inside of the case, enhancing airflow.

There is a 135mm fan on the bottom of the PSU to move extreme amounts of air to keep everything cool. The back panel is a honeycomb mesh broken only by a switch, the power plug and an indicator LED for virtually unrestricted airflow. Go ahead; build the system of your dreams, the ST1000 can handle it.

5 out of 5 eggs

Pros: 1000 watt, TRUE modular design, good quality, great support.

Cons: Mine came DOA...

Other Thoughts: I have owned this for just over two years now, and have had not one problem, even lost power while running several times. Came DOA but Newegg got one back to me in no time. DOA's Happen...

5 out of 5 eggsEgg-cellent Power Supply

Pros: Modular design a total plus! What you don't need doesn't have to be there. Rock solid and stable under high load demands.

Cons: A little pricey, but you get what you pay for!

Other Thoughts: I've had this for almost a year now and I have had ZERO problems with it. I don't know what problems the guy with the 8800's had, but I have twin 8800 gts running 24/7 since I built this thing and have had no issues. I also have it plugged into a surge protector (and no, it's not a "whole house" protector) and have had no incidents. This is an egg-cellent power supply. I did not purchase mine from new egg, but at the time I needed one immediately. If you get this power supply, you shouldn't have any worries. My computer: Intel i7 920, Gigabyte EX-58-UD5 mobo, 12 gigs OCZ Triple Channel High Performance DDR3 1600 (all bought from newegg), 3 500 gig western digital caviar HD's, 1 western digital external 1 TB hd, 7 120mm cooling fans (green L.E.D.), two L.E.D. temp/speed controllers, 2 cd/dvd/lightscribe drives, 2 nVidia 8800 GTS (for now) all settings at maximum, running Win XP Pro 64 bit and Win Vista Ultimate 64 bit.

5 out of 5 eggsSilverstone 1000watt st1000

Pros: Unit is fully Modualar. Have had no problems at all,

Cons: Wish that they would have included a cable for molex with only 1 power connector(not a biggie), PRICE (Wish power supplies of this wattage and caliber didn't cost so much)

Other Thoughts: I bought this power supply with intentions on using it for my next build in a couple of years.

5 out of 5 eggs2+ years and still strong

Pros: modular cabling is very nice, I bought this when modular psu's were still new and I am buying this same one (or maybe the ST1200 that is 80+ certified) for my new build.

Have never had a problem with surge suppressor, CyberPower 1010HT 4200J suppression Item#:N82E16842102049

cables are sleek and stiff, great for lesser air resistance

Cons: no cons, has worked wonders for over 2 years (so 5 *'s from me)

Other Thoughts: I didn't buy this from Newegg, got it at local store because it was the last thing I bought for my build and didn't want to wait for shipping lol.

Works fine in Full Towers, might be hard on Mid Towers due to stiff cables

2 out of 5 eggsWorked for awhile

Pros: Modular cables, lots of power, looks nice, cables are sleeved

Cons: Died after two years, expensive

Other Thoughts: This worked for awhile, but after two years it quit. The fans would spin up, but nothing else would happen. It has a 3-year warranty, so I suppose I can get it replaced. For the amount of money it costs, there are newer power supplies that are much better. I replaced mine with the Corsair HX750W.

5 out of 5 eggsMassive PSU

Pros: Plenty of connections and capable of removing unused cables for better cable management. Huge fan as mentioned by another reviewer and quiet operation. Sorry to the guy below with PSU issues, but this powers my GTX285 on dual 22" monitors (via a high-end surge suppressor) just fine. It wasn't the latest game, only COD:World at War at 1680x1050, but still...

Cons: None. Stiff cables, I can't imagine using this with a mid-sized case.

Other Thoughts: Bought this PSU to accommodate any expansion to 12MB RAM and power left over. Had to invert it as fan is on the bottom, but that's not uncommon.

5 out of 5 eggsGood

Pros: Powerful power supply for almost any computer. This power supply has lasted me for well over a year now. I have had no problems out of it.

Cons: Another 4-pin connector or the twin 4-pin connectors that connect to make the 8-pin should of had the ability to seperate further.

Other Thoughts: This power supply will be removed from my current setup to my new setup in the next few days.

5 out of 5 eggsTwo Good After 1 Year

Pros: Lots of power, modular cables, great price with rebate, stable & accurate voltages, active PFC, dual 12V rails

Cons: Larger than stock power supplies, not 80+ certified

Other Thoughts: I've been running two of these for over a year without any issues. My main system has 5 hard drives, 3 DVD drives, GTX 260 video (uses two PCI 6 pin cables) 9650 Quad Core Extreme, DDR3 memory and 8 x 80mm fans and this power supply doesn't get winded. All voltages are within 2% and stay stable during hours of use. Price is quite reasonable with Silverstone rebates which arrive quickly. I would not hesitate to buy another.
