FSP Group Booster X5 450 W Independent/Supplementary SLI Certified CrossFire Ready Active PFC Dedicated Multi.GPU Power

Pros: This thing is the perfect solution to anybody who needs additional power for upgrading their graphics card. Had I had a larger tower it would have worked nicely in a slot. It isn't all that bad externally though. This thing runs silent. There were a few times that I thought it wasn't even on until I put my hand over the cooling vent. Runs cold even while playing games on highest graphics settings for hours. Buying a larger power supply is nice to do, but this running separately is (in my opinion) a way better option if you have a slot to put it in. There are 3 reasons for this: 1. Very large wattage PSUs are more expensive than adding this. 2. This spreads the heat instead of concentrating it at the power supply. 3. This will extend the life of your existing power supply by reducing its load cycle.

Cons: If your PSU doesn't have an extra molex 4 pin cable you will need to buy an adapter. Would have been nice if it came with a female SATA to female molex adapter. If your PSU doesn't have any extra cables (molex or SATA) you will need to buy a splitter to add one. This syncs the booster and is the only way to turn it on.

Overall Review: Anyone who complains about the light not staying the same color is a goofball.

Pros: nice cables, construction has a quality feel to it. Seems to work perfect to power my two 8800gt's.

Cons: Whoever designed this thought it would be a good idea to make that giant X on the front of the unit glow and change colors. The documention that comes with it is only a simple installation guide, and does not mention this 'feature'. It also makes noise: it sounds exactly what you'd hear when defragging an old ide hard drive. I assume this is from the two fans, one placed on either side of the X behind a chrome plated grate.

Overall Review: Experimenting shows you can change the color of the X by pressing it, as it is also a button. Colors include: green red yellow blue teal purple white (off)

Pros: Fits in a standard CD/DVD bay, has enough cables to run your cards in SLI, cool changeable lights in front and grill which presents case really nicely, dedicated power so it relieves your main PSU from unnecessary stress, works great and easy to install

Cons: Haven't found any yet ....

Overall Review: If you need that extra power for your GPU's this is a PSU to you should get. (I have my XFX 9800 GTX Black Ed OC'd at 850/2125/1200 and have yet to see any problems)

Pros: Just what I need to avoid buying a very expensive 1000W + power supply. Everything fits well. Even the power cord was long enough for my very long SuperMicro server case. Enough power for a single GTX 295. Product is very well designed with high quality cables and hardware. FCP is the parent company for Sparkle, which are highly regarded for reliability. Using the 4 pin connectors for a turn on signal is genius. You don't need those spliced 24 pin power supply mobo connectors as you would for an aux AT power supply.

Cons: The colored X on the front panel. But mine stays off when re-powered so it's no big deal. You also need a spare 5.25" drive bay, and need to be sure the rear is clear of cables to provide air flow from the back to the front.

Overall Review: Was seriously considering a 1000W power supply until I found this product. Have you noticed how many folks are reporting failures with those high power supplies. Some cases over 30%! This is a great alternative, as I have a 650 W supply installed already. It is custom with the SuperMicro case, so retrofitting a 1000W supply would be a nightmare. The 450W rating is power where you need at, at the 12 V bus. Make sure you have clearance behind the unit for cooling air flow. Should power a single gxt 295 (at 300 W max) no problem. Don't think it will power more than two gxt 285's in sli though. Certainly not two 295s which would require 600W. This product is much easier to install and cleaner than a second outboard AT supply if 450 W is enough power. And for those commenting on the two prong plug, this is necessary to float the ground. Otherwise you will have ground loops. Another reason using an outboard supply is complex, as you now have multiple grounds in your system.

Pros: - Easy install - Not very expensive - Air blows out of the case, not in. - Removes the need to upgrade your main PSU in most cases.

Cons: - The big X in the middle of it that changes color..could do with out it. Not a big deal though. - Could use a longer internal power cord. I have a midtower case and didn't have any issues. But in a bigger case it might cause a problem.

Pros: I purchased this unit about 3 weeks ago to run my sli setup that I have (twin gtx 260, core 216 units) and all I can say is one word..flawless! TOTALLY worth the money if you are a little short on power with your current psu or are having doubts about pushing it and possibly burning it out. The X5 installed in minutes and powers up and down via a molex connector from your main psu. Very easy and slid right in to my open 5.25 bay with NO problems at all. Looks cool too with a large X on the outside of it that glows different colors each power up. It gets it power via a expansion slot in the back of the pc that you add so a regular power supply cable plugs into the wall to feed it like a normal psu, so its totally self reliant. Pushes my sli setup EASY! GET IT!!

Cons: none really..

Overall Review: Bang for the buck ratio is very high if you dont feel like changing out your current psu or are worried that a larger more powerful psu might not fit your case. PERFECT FOR sli/ Quad SLI setups! VERY NICE!!! THANKS NEWEGG!

Pros: A breeze to setup. Looks slick/fancy. Nice and quiet.

Cons: Everything has to have one problem. For this item it would only have to be that it has to be the tightest fitting 5.25" bay item ever. I have a Cooler Master case with fancy quick release rails for the bays which could of been the problem, but either way my optical drives fit nice but this guy took some strong arming to get it to slide in. (my wife came and took the dog up stairs because i started yelling and throwing stuff.)

Overall Review: Did a lot of reading on the inter-webs to find out all i could on running crossfire video cards. When i ordered my current PSU it said SLI/Crossfire ready but when i did my research i found it it didn't pack the power needed to run Crossfire 6870 video cards. I didn't wanna drop the coin on a $200+ PSU just to run one extra video card. This item was recommended to me by a friend and i must say it fit the job perfectly. I am able to run both my video cards off it (both are XFX 6870's / one is dual fan the other in single) with out a problem.

Pros: Compact and good looking unit. I have this external to my OptiPlex 760 Desktop powering a low profile Sparkle 9800 graphics card. Made up power plugs etc and have the unit switching on and off using the standard PSU 5v rail. Very pleaed with the performance.

Cons: The coloured led setup is silly. I painted over them to reduce the X brightness but I might end up just using tape to completely eliminate them. The fans are probably louder than needed. Given my card will only ever draw 25A of the rated 35A of this PSU I might look at slowing them down a little.

Overall Review: Should also note both of the fans on the front pull air in and push out the back of this unit - not a problem for me as I have this external but might be an issue for some who mount this internally as intended.
