3 out of 5 eggsST1500 not a good choice for mining

Pros: Quiet: practically silent
Impressive total wattage

Cons: Too many rails and insufficient connectors: Hard to get full wattage out of the power supply without splitters/adapters.
Insufficient wattage to (4) PCI-e rails to power (4) mid range cards
No power switch (what?)

Other Thoughts: For mining you are much better of linking two 750-850 watt gold-rated power supplies with a high quality Y cable. It will be a lot cheaper and you'll get single rails with lots of connectors. Also, modular connections are useless for mining rigs, and actually an additional point of failure. Avoid this unit for that purpose.

1 out of 5 eggsPop!Spark! Dead...

Pros: Strong unit, modular cables, lots of power

Cons: Died with less than 300 hours of up time.

Other Thoughts: This was installed In system that isn't on 24/7. Total uptime since installation is under 300 hours, turned it on, and with a flash of sparks out the back of the unit and a loud POP, the unit is dead.

1 out of 5 eggsCan't power a hard drive

Pros: Modular, which doesn't mean much if it doesn't work

Cons: Apparently it can't power a single hard drive

Other Thoughts: Everything was great until I powered it on and it failed less than ten seconds into the boot cycle after adding a single 250GB hard drive. Confused, I switched the power cable AND the SATA cable out and it still failed as soon as the hard drive spooled up. Suspecting the hard drive, I put it in one of my other machines and it worked perfectly, initializing in Windows, transferring files and everything. I then took a completely different hard drive out of another machine and plugged into the ST1500 and the same exact thing happened: complete failure within ten seconds of applying power. The fan stops and everything on the mobo goes dark. I even disconnected the video cards, the SATA connection from the hard drive and everything else except the CPU and RAM with the same result. I tried all of the six pin ports and it still failed. The only way I could get it to work was unplug the hard drive and it would work just fine.

Summary: PSU fails anytime any hard drive is connected.

2 out of 5 eggsShould You Go Elsewhere For Your PSU?

Pros: Modular
Nice Boxing

Cons: No turn-off switch on the PSU itself

Unreliable Longevity

Unreliable Product

This is my second 1500W Strider Series Power Supply in the last 4 years. The first one I bought worked fine for just a litle over 3 years while running a 480 fermi. After that period, it just died and refused to turn on. Since I had no problem with it in those three years, I decided it was probably a rare fluke and decided to fork out another 400 dollars to buy another. To my dismay, after upgrading to two 780s in November of this year, the power supply would cut out after about an hour of gaming (This would happen with a single 780 or in SLI). I thought it was the GPU at first, but I've used these same card on my friends rig for days with no problems while I was switching out parts in order to assure myself of the culprit: the PSU.

Unfortunately, my PSU really doesn't like 780s, and will shut down even though my GPUs aren't overclocked like some of the other individuals having problems in this 1500w review.

Therefore, due to my experience, I cannot recommend this PSU to anyone. Since my newest one was purchased in May of this year, I'll likely try to exchange it. If, by chance, this fixes the problems I've been encountering, I'll update this information; however, if a refund is applicable, I'll certainly go that route--again, updating this info accordingly.

TL;DR: Apologies, but I cannot recommend this PSU to any individual.

1 out of 5 eggsIt was good until...

Pros: Bragging rights, 1500w psu. What more can I say? It did it's job powering everything at stock (honestly, even a 650w could of done that).

Cons: I've had this since December 2010, and after a year of ownership I I threw in 2 GTX 480s to sli but it would BSOD, so power rated at 1500 very nice, more like 550w. But I decided not to pursue it after replacing the two with one 580. So flash forward to now at the end of 2013, the fan in this thing starts to sound like a helicopter propeller spinning, and it's louder than everything else in my computer.

Other Thoughts: Even after all the failed attempts at OCing because this PSU couldn't handle the increased voltages, I still have faith that it could handle Quad SLI. I have to stop giving this thing the benefit of the doubt.

Manufacturer Response:

1 out of 5 eggsLT Follow-up

Pros: plenty of connectors

but not enough amps per rail

Cons: too many rails. This PSU was able to run crossfire 7970s... but blew after about a year. Silverstone sent me a replacement under warranty, and this "new" unit is not able to run even ONE OVERCLOCKED GTX TITAN. Forget 2 titans. Even splitting it up as a two PSU rig - with one card on my PC Power and Cooling 1200 and the other on this ST1500 - this replacement shuts down, while the PC&P unit, which is powering the OCd 3930 and a titan does fine.

Other Thoughts: Just not enough amps (only 25A) on each rail. Using two rails on one card and it fails! Yes - I know a heavily OCd Titan can draw 900W - this PSU cannot handle it.

Also - lots of "snap and crackle" in the replacement Silverstone sent.

I WAS a fan of Silverstone products however, this experience has changed that.

1 out of 5 eggsNot for mining

Pros: N/A

Cons: Will not support more than 2 GPUs.

Other Thoughts: I wish I just bought a seasonic or a EVGA

Manufacturer Response:

Thank you very much for purchasing a SilverStone. The ST1500 can support up to four graphics card as shown by Maximum PC magazine in their Dream Machine 2011 build in the link below:

Numerous system integrators have also used ST1500 as the basis for their multi-graphics card systems. If your ST1500 has problem supporting more than two GPUs, please contact us directly so we can help you diagnose the problem or to help you replace it if it is defective.

5 out of 5 eggsFantastic

Pros: I am almost at 4 years of using this PSU and its fantastic. Great build quality and heavy. The modular design for cabling allows you to setup your case as neat as you desire. You can throw a tri-sli setup on it with every thing over clocked and nothing to worry about. Its also silent to my ears.

Cons: none

Other Thoughts: I am currently running a 990x OC to 4.6 and tri-sli titans with 4 HD. I have hit 1100+watts while benching (kill-a-watt) and have never had a problem.

1 out of 5 eggspiece of s

Pros: worked great for the first 7 months I had it.

Cons: Only worked for 7 months, desktop won't even stay on long enough for me to login now. Biggest piece of s I've ever wasted my money on.

Manufacturer Response:

Thank you very much for purchasing a SilverStone. We stand behind the quality of ST1500 and since its initial release in 2009, it has been one of the best power supplies ever released. It is used by motherboard and graphics card makers as a reference PSU in addition to being used by major boutique system builders. Please double check again to make sure your system is not experiencing other problems and if all power supply connections are secured. If you have determined ST1500 to be the point of failure, please contact us directly for information on how to return for a warranty replacement. Below are our contact information:
