OverviewCustomer ReviewSpecificationsProduct Tour
You've just upgraded to an SLI or Crossfire video card, and now you need a little more power from your power supply. Silverstone just might be the answer to your need.

Rated at 700 Watts and greater than 80% efficiency, it also features RoHS compliance and active power factor control, making this one of the "greener" power supplies around. Modular cables allow you to install only as much cabling as you actually need. This saves room and preserves clear airflow inside your case. Four +12Vdc rails for clean but heavy-duty power distribution, while 100K hours MTBF means reliability.

With four PCI-E6 and one PCI-E8 connections, two floppy drive and six peripheral and six SATA connections, you won't run out of connectors soon. Whether you're running a server or you're a hard-core gamer, this power supply can do the job. Check out the specs for yourself and decide, but this could be the power supply you need.

This user purchased this item from Newegg
Pros: Plenty of cables for everything i will ever need to power up my computer. The modular cable support is sweet and allows me to keep the inside of my case clean and organized. This supply has enough juice for 4870s in crossfire, 3 hdds ( 2 in RAID0, 1 nonRAID) , and more!
Cons: None
Other Thoughts: Seriously, modular power supplies are the way to go. I remember back in the days when i had to smoosh in the extra power cables into a 5.25 bay to get them out of the way, and even then it was still somewhat messy.

Tech Level Tech Level: high - Ownership: 1 month to 1 year
This user purchased this item from Newegg
Pros: -Fully Modular Cabling
-135mm fan moves a lot of air with low noise generation
-Supports SLI
-700w is more than enough power
Cons: -No on/off switch. Not really a con, just different.
-Being fully modular is unnecessary, 20+4 and 4+4pin motherboard cables don't really need to be, but it is nice for installation purposes.
-Only includes one 8pin PCI Express cable, so running dual graphics cards that each require one 6 and one 8 pin will require an adapter, unless additional cables are available from manufacturer.
Other Thoughts: This is a solid runner, albeit complete overkill for my current rig. I'm running an Athlon X2 5000+ BE, 8800 GTS 640mb, 2gb or RAM, and a hard drive and optical drive or two. I bought this along with the NZXT Tempest case to be the first two components of a new build, but never got around to the rest. Owned/Using both since Feb 09.

Tech Level Tech Level: high - Ownership: 1 month to 1 year
This user purchased this item from Newegg
Pros: Plenty enough power for most gaming rigs out there.

Fully modular cables. If yer a case modder like me this is a huge selling point as it allows for the creation of custom length cables for any kind of cable routing you could think of.
Cons: I haven't found any.
Other Thoughts: Thankfully not oversized like so many other PSU's out there. It's a nice normal size and not overly long which can make for a tight fit in mid tower cases.

This user purchased this item from Newegg
Pros: Excellent PSU. The modular cables are sleeved, and high quality. Installed perfectly, and provides plenty of power. Comes with more than enough cables for all your gear.
Cons: It has a 20+4 pin connector. The 4 extra pins do not have a clip, so theres nothing holding it in the socket. Has no external power switch.
Other Thoughts: none
