SilverStone ST1500 1500W Power Supply

Reaching 1500W DC output (1600W peak), the Strider ST1500 is effectively at the limit of what an internal PC power supply can achieve in terms of wattage rating. For SilverStone, getting to this maximum power for a consumer-level power supply was only part of the goal, so every desirable feature known was added to create a dream product. The list starts with an unprecedented eight +12V rails, each capable of up to 25A, and continues with features such as 100% modular cables, 80 PLUS Silver-worthy efficiency ratings, and a quietness level that matches most 500W PSUs. If there is one upgrade that will likely outlast a PC enthusiast’s interest in computing, the ST1500 may just be it.

Won't fit in two different cases - the mains electric socket is not positioned properly

Pros: None - I could never use (tried two different cases)

Cons: Cases have cutouts with mounting holes to secure the PSU - on both cases I tried, the holes were lined up correctly, but the plastic surround of the electrical supply receptacle prevented the PSU from being positioned. Only solution would be to grind down the case, or else the plastic of the supply. This should all be spec'ed out measurements. In both the cases, other brands of PSUs fit perfectly without any blockages (one a supermicro workstation chassis and the other a Phanteks Ethoo. I had originally purchased this in 2013 (!) as a replacement for what I thought was a failing PSU in my workstation; when it didn't quite fit, I saved it, thinking that someday I'd build another since I'd gotten a good deal. 5 years later I pull it off the shelf only to find it doesn't fit in my new case either! Jeez. Wish I'd just returned it ASAP.

Lasted under a month

Pros: 1500w, well reviewed, was in stock.

Cons: Died in under a month (~22 days from purchase) with a 1200w load.

Overall Review: Disappointed with Silverstone. I've had their products in the past and they've always seemed to exceed expectations. Hopefully this one was a dud. Wouldn't be that big of a deal if Newegg and everyone else wasn't price gouging on basically all computer parts atm.

Manufacturer Response:
We apologize for the inconvenience, this is very unusual for this power supply. It has great specs design, it is very solid, stable, and it has been in the market for several years now. This particular unit certainly has a problem please contact customer service to get it replaced.

Nowhere near rated power

Pros: - Lots of cables and connections
- Quiet fan

Cons: - Nowhere near rated power.
- Sata cable burned up running 6 risers. Same 6 risers are now running fine on a corsair CX750M
- System powers down at 1200 watts on the meter

Overall Review: 2 750 watt are considerably cheaper and do better.

For the power hungry system, this is it!

Pros: -Tons of connections
-1500W duh!
-100% Modular
-Expansion expansion expansion
-Very nice covering for all wires
-Whisper Quiet even under load

Cons: -It actually dims the lights when I turn it on (like a vacuum might)
-Some of the wires with their covers could be tighter
-You need a massive case and even then, this PSU is going to take up a TON of room (but it's 1500W so DUH!)

Overall Review: My only... not even complaint really, with this PSU is that the covering for the wires could be thinner or tighter to the actual wires. It looks fantastic but it can make cable management somewhat of a pain in very specific scenarios. Not near enough to drop an egg. This thing is a beast, and it is WHISPER quiet, even under heavy load.

This has been powering my system for nearly 5 years and is still running like a champ. 10/10 would buy again!

Review after 1 week of use

Pros: -Fully modular as advertised
-Quiet fan
-Supplies ample power to all components
-Installation wasn't too hard after some studying of manuals and sorting of cables

Cons: -None so far!

Overall Review: So far, this has proven a great buy, has enough power that if I upgrade later I won't have to buy a new PSU. Plenty of empty slots left to use.

Fried 2 pins in the PSU and on the motherboard! Very limited warranty... STAY AWAY!

Pros: -Has plenty of head room for all your gadgets
-Fully Modular, makes it easy to tidy the inside of your case

Cons: -No On/off switch. Why?
-Limited Warranty only 1 year
-Fried in two locations, one on my PSU and one on my motherboard.

Overall Review: I would steer away from this product. It failed on me shortly after the warranty expired. Silverstone pretty much said, "Sorry about your luck, nothing we can do if its outside the warranty period". I mean, its not like you're paying $290.00 for this piece of brick. It melted and fried in two locations. One was the modular side where you plug it up into the Power Supply and the other was in the same exact location on the motherboard. Both places were melted on both sides of the 24-pin. No I wasn't running it on load, and no I wasn't even overclocking. I barely hit 800 watts because I bought this for an overkill head room. I was only running a i7 950 at the time and 2x GTX 580's. Now I'm stuck with a $289.99 brick and a useless motherboard that I cannot use due to it having friend 2 pins in my 24-pin slot on the motherboard, and also the 24-pin modular slot on my Power supply completely black and melted.. Do yourself a favor.... there are plenty of companies like Antec and EVGA that will give you at least a 5 year warranty on their Power Supplies. Its such a shame that this one failed shortly after a year and that it ruined two of my products. Kind of makes me wonder why they include such of a short warranty period on the product that you claim to be "Top of the line". Sounds a little skeptical to me. Either way this made me learn my lesson to go elsewhere when it comes to Power Supplies. But Hey! Look at the bright side, I ended up just upgrading my whole entire PC after this happened, so I guess there is a positive side to this. I also went ahead and got a Antec HCP-1000 Platinum with a "7"...... yes "7" year warranty. Thanks for nothing Silverstone.

Not worth the problems

Pros: - Worked great, until it didn't

Cons: - First one shipped DOA got an RMA
- Second survived 4 years until today when I turned on my PC to a loud audible pop and a fried PSU

Overall Review: Not even sure about the rest of my PC until I get my newly ordered PSU and I can only hope it didn't take anything else with it. Not even close to the maximum load.

Worth it I guess?

Pros: Actually uses less power than lower rated PSUs

Cons: Didn't really have any

Overall Review: 51 months of ownership, fan failed. I do not know if the unit is damaged due to heat. System began shutting down for "no reason."

Spent $400 on mine in 2011. Can't afford to straight replace it at this point... very bummed. Cannot find a replacement fan that I know for a fact will fix it.
