Did you get your system configured the way you wanted and then realize that you needed more power for your graphics cards? You could go the traditional route and get a bigger power supply. Or you could go in a new direction and get the BoosterX 3 from FSP.

This supplemental power supply fits in an unused 5.25" bay and delivers 150W to each of two 6 pin PCIe connectors. This takes a large portion of the load off of your regular PSU so it can use its power for your CPU and drives. You can also stack boosters for today's power hungry cards with multiple connectors or the Tri- and Quad- SLI configurations coming out.

  • newegg Supplementary Power Supply The FSP Group BoosterX 3 FSP300-1E01 fits easily into an unoccupied 5.25" drive bay, providing additional 300W power to support your high-end multi-GPU graphic interface card power requirements.
  • newegg NVIDIA SLI Certified The FSP Group BoosterX 3 FSP300-1E01 power supply has gone through a series of rigorous NVIDIA SLI certification tests for maximum system stability when building NVIDIA SLI PCs.

1 out of 5 eggsMakes annoying sounds

Pros: Powers another graphics card without spending hundreds on a new PSU

Cons: noise noise noise

Other Thoughts: Almost always this unit makes an annoying clicking sound from the cooling fan. I wish I could open it up and find out why or send it back to get another but then I would have to pay to ship it back. This is the second item I have bought from here that is broken and I have only ordered 4 or 5 things from here. I'll never shop from here again no matter how good the prices are(even though when you look elswhere you can get it for cheaper).

1 out of 5 eggsLoud, Poor Design, Short lifespan, No Support

Pros: None.

Cons: Where to start?

First off, its very ugly. The blue led and the rounded plastic thing protruding from the case is terrible.

It uses up a molex connector from your existing power supply. Totally unnecessary.

It is not grounded or shielded well. It caused extremely loud buzzing and other interference through both internal and external sound cards and headphones.

It is loud, very very loud. I measured it above 41DB while in the case. Which is about as loud as my 2 500watt power supplies running while not in a case.

It died after 5 weeks.

Endless phone calls and emails to the company have never been answered.

Other Thoughts: I will never buy another product from this company.

After this died, I bought the Thermaltake W0157RU 450W as a replacement. Its like night and day. Its built great, looks great, is super quiet (I measured just over 19DB), has a 3 prong plug so its grounded properly and doesn't cause audio interference, and doesn't require stealing a molex connector from your existin power supply.

5 out of 5 eggsThis thing is awesome

Pros: It powers a single GTX 260 perfectly. The two 6 pin connectors provide plenty of power. I can now use any old (name brand) 400-500W power supply in my main rig now, without having to worry about rails, amps, etc. It makes it so that I can swap out PSUs between all my computers easily if I have to. Also, since it is a separate entity from the main PSU, it is unaffected by, and does not affect, the load on the other components.

Cons: It's not clear if there are two rails, or one rail. It requires routing a power cable through the back of your PC, so cable management is tougher if you're a cable freak like me.

4 out of 5 eggsJust Works

Pros: I installed this into my HP Slimline so I could run a 9600GT. Works great.

Cons: None, other than having to remove DVD burner to put this in.

Other Thoughts: It just works.

5 out of 5 eggsGreat PSU.

Pros: Allows for expansion within a system not designed for expansion; runs my ASUS EN9800GT ULTIMATE without a single problem.

Cons: Very heavy; then again it is a PSU crammed in a small package.

Other Thoughts: I bought a $450 Compaq PC off the shelf and wanted some way to turn it into a gaming PC without spending a lot of cash. Such systems aren't meant to be turned into gaming rigs, however this PSU allowed me to do just that. I plugged it in and it is happily powering my ASUS EN9800GT ULTIMATE GPU. It is a bit heavy, but I guess that is to be expected from so much being packed into a small package. It fit right into my drive bay and was easy to install. Not a fan of the blue LED-lit plastic cover... thing, that sticks out, but it isn't so intrusive that it would be much of a bother. More of an aesthetic preference, really. All in all I am very happy with this PSU. I would recommend it to anyone who needs/wants to beef up their off-the-shelf Dell/Compaq/HP/etc. that wasn't meant to be a gaming rig but still want one without spending the ridiculous amount of cash required for a gaming PC.

5 out of 5 eggsWorks Good!

Pros: It does what it's suppose to do! I have this in an HP Slimline powering a low profile 9600GT and it works great! It's also doesn't get hot and the fans aren't loud on it at all.

Cons: Absolutely has to have a molex connector to turn on. Didn't really like that since I had to convert a SATA to one. Also it would be better if somehow the second PCI-e wire could be disconnected from the plug to save space.

5 out of 5 eggsQuality part

Pros: Build quality seems very high - I judge power supplies by weight, and this thing is a porker!
25 AMPS to your sli cards - this is more important than wattage.
Looks better in person than the pics.
Comes with everything you need to install, and was very well packaged.

Cons: Not real enthused about the led's and the clear plastic cover in front, but it does look better in person than I expected, and the competition is really ugly.
I wish it dumped the heat out the front of the case instead of pulling air in- I'm using this in a micro form factor pc and there's only one system fan for both the cpu and the case, and no room for extra fans.

Other Thoughts: Really the only solution for a high powered vid card in a micro pc.

4 out of 5 eggsGood alternative

Pros: Good alternative when you have a power supply that can't go run cards like the 3850/4850 in crossfire or if you have prebuilt machine with a proprietary power supply. Mine comfortably ran a 3850 with a 3870 in Crossfire X. Very nice PFC on this.

Cons: It is noisy than my whole computer in IDLE mode. When it ramps up to high speed, I can actually hear it over my Xbox 360!!! You have two power cables to plug into the wall to run your computer.

4 out of 5 eggschepa alternativce to a high end PSU

Pros: Much cheaper than a high-end PSU. Quick install, simple install runs a pair of HD3850s overclocked to 823/1044 without issues

Also it makes no noise the 40mm front intake fans are silent.

Cons: faceplate is to big so the door to my case wont shut properly. My case is an Ultra Dragon.

Other Thoughts: Great buy if you don't want to spend a huge sum on a high-end PSU
