An important tip from one of our users: don't just check total power output, find out what you need in the way of current on each power rail. If you need 20 A on your +12V rails and the supply only has 15A, it doesn't matter how many watts the supply puts out: don't buy it. Make certain that you have ENOUGH rails, too: sometimes, you need more than just two +12V rails for your setup.

Replacing an existing power supply is easier: just get a replacement that meets or exceeds the specifications of the old one. (You can usually find those printed on the side of the supply.)

That said, here's a power supply that is compatible with most ATX format motherboards, puts out 750 watts of power (see specifications for exact distribution). Could this be your next power supply?

4 out of 5 eggsKinda Modular

Pros: Works, fits, and was easy to set up. It's nice and heavy, and the cables are more then long enough.

Cons: I bought a modular power supply to cut down on cables, but so many of the cables included had several plugs attached, and the cables were kinda long. In all I think I ended up with MORE cables in my machine then before. This isn't a big deal since I had the room to stuff them aside, but others might find it annoying.

Other Thoughts: I'm a little disappointed since I was expecting to reduce the amount of cable inside my computer. However I will probably not have to upgrade to a different power supply for a long time since many of the cables included could support many upgrades. In a year I'm sure I'll be very happy with this choice, but right now I'm looking for some zip ties so I can keep the cables from hanging around in bad places.

5 out of 5 eggs3 years on and still working

Pros: Have had this PS in my wife's computer for just about 3 years now, and have had no problems. This computer is on for just about the entire day, just chugging along. I really like that you don't have cables all over the place in a machine, which was the main reason for going with a modular PS.

Cons: It won't clean up the cat's hairballs

Other Thoughts: The machine's been running a Core2Duo for 3 years now, 64-bit Windows (yes, Vista), Raptor drive, and a couple of other hard drives as well.

4 out of 5 eggsGood price, rep brand, decent amt of power

Pros: $125 for a modular psu! Silverstone is very well regarded by many gamers who push the limits on peripherals which need all that power. Big 200 series cards and several opti drives, audio cards, etc. 750 watts should be your hw tho' add up how many drives, cards total watts will be used to see if 750 covers it. I bought an 850w non-mod pus in 2007 that was from another good mfg and was so much more! I also use 1- XFX 9800 gtx card so i dont need a 6+2 pin pci-e x16 connector just a 6 pin one.

Cons: If youre going to upgrade to a 200 series graphic card, this isnt the psu for you. Thats why its $125. That is really the only issue i can think of and if you have an 800 series or a 900 series, grab it!

Other Thoughts: Thermaltake TR2 W0366RU 700W ATX 12V v2.2 Modular Active PFC Power Supply. This is not as strong by 50w but may have those connectors you need for 200 series and its also about $125 and another decent brand co to consider here on the egg. S/H is $10 and psu is $114 or so...

3 out of 5 eggsPoor life span

Pros: Does what its made to do. Good wire management system.

Cons: Died after 2 years of easy use. Its hard to understand how a PSU dies when you only pull at most 400 watts at the plug, and its rated at 750.

Other Thoughts: I have surge and UPS on all my systems. If i was drawing godly ammounts of power threw it i can see it, but ive been using it on an HTPC system for over a year now. And even when it was my gaming system, I never drew anywhere near enough power to cause this unit to fail after only 2 years.

3 out of 5 eggsNot bad, but not great, especially for the money.

Pros: Has reliably provided power for my High End HTPC for almost two years. The system has a GTX 260, a pair of 7200 RPM drives, and a quad core processor. The case is very cramped (I had to bend heatsink fins on the CPU cooler to get everything to fit and use tin snips to make room for the video card, what you get for shoving a high end gaming PC into an HTPC enclosure) and runs pretty hot. Power has been completely reliable, though.

Cons: The fan that it came with failed in short order. I replaced it with a ballbearing fan within a month or so of buying it, which has worked fine since, but for the price and power level a deceont fan should have come with it.

Other Thoughts: I probably won't buy another power supply by Silverstone. The case I got I still like, though.

1 out of 5 eggsIf this fails, don't count on support

Pros: Worked fine for 2 years, 364 days, and 12 hours.

Cons: The 13th hour is what kills ya! Immediately after it failed I ran all the tests I could in order to determine it was a faulty power supply. Once I had it pin-pointed I sent in an RMA request to their technical department. Through conversation over the next day (after warranty period at this point) technical support said to submit to RMA department. When I did submit the request to the RMA department they said it was after the warranty period EVENTHOUGH I had e-mailed technical support requesting RMA approval. MOST companies require you to contact tech support for an RMA approval number. Why is Silverstone any different?

Other Thoughts: End of story: Never purchasing from them again because I know in my heart that they will find some excuse to avoid supporting their product. This was a $200 PSU at time of purchase

1 out of 5 eggsNot Happy

Pros: Moduler Connections - don't have to use all the cables.

Cons: Sata Rails, not split up? - Non-working unit. Ever since I got this thing. It hasn't worked, never will post my board. I try my Antec 650 Earthwatts and it post's, even my dieing Apex(allied) 450W supply works. So I sent it back, guess what? they sent me the SAME DEFECTIVE PSU and put a Different Serial on it. I marked it with ultraviolet ink, that's how I know. An it Still Don't WORK!! I have never gotten to use this PSU!!

Other Thoughts: just from what I've read here, I could be on this marry-go-round for awhile, might as well just send me the 149.00 back! I'm never buying SilverStone Again!

Manufacturer Response:

Thank you very much for purchasing a SilverStone and we apologize for the inconvenience you have experienced. Our RMA process does not involve changing the serial number on our products (in fact we do not have spare serial number stickers at our US facility) so we are very surprised to hear about your experience. If possible, we would like to help you get a working power supply as soon as possible. Please contact our US office directly at:

3 out of 5 eggsNice Product .....

Pros: Very nice power supply with nice design

Cons: Not for the 4870x2...with only 18A per rail it does not supply the 54A needed....It has given me random P.C restarts on random games...Very frustrating but in no way Silverstones fault....I just needed to do my research better first....Great unit for less demanding hardware.....

Manufacturer Response:

Thank you very much for purchasing a SilverStone. If you are using only one 4870X2 graphics card, the ST75F should be able to support it without any problems. If you haven't already, please try switching one of the PCI-E connectors with another available one from the power supply (so two separate PCI-E cables are connected to your 4870X2) to see if this will solve your problem.

5 out of 5 eggsPower Up

Pros: This power supply has never given me any problems and has worked flawless to power my system for the last 1.5 years. I really truly enjoy how quiet it is and how it's up-time is superior. The quality is one to a great Server PSU. Buy it!

Cons: None, it has a fan? Get dusty like all? HAHA.

Other Thoughts: I don't do reviews to much only on product that have given me no problems for more then a year.

3 out of 5 eggssounds like a leaf blower

Pros: 750 watts
4x 12v rails
FULLY modular.
separate cables for Intel vs. AMD Processor cables which just looks better.

Cons: the fan is LOUD. the box advertised that it runs on silent operation, this is not the case at all. I'm sure that the CFM is much higher on this fan but it is really excessive.

Other Thoughts: after a stress test using OCCT i found that:
VCore@ 1.4875v actually had an output of 1.55v with a 4.04% ripple
12v Rail had a 3.66% ripple
5v had a 2.17% ripple

In conclusion, This is a good power supply for a lower end system that will not be stressed as much. I find that the ripple in the voltages are a little too high for my liking, and the loudness of the fan is a major drawback for those that are looking for a silent PC. Will be RMA'ing for a refund once a new PSU arrives.

I would rate this lower, however it is really hard to find a fully modular PSU these days so it deserves a better rating for that much.

Manufacturer Response:

Thank you very much for purchasing a SilverStone. From your description, the unit you received may be defective. The ST75F has a built-in fan controller that should regulate its own fan to lower speed for very quiet operation when start up and also during most loading conditions. The fan should not sound like a leaf blower at all until it is drawing at or near maximum 750W of power.

If you haven't already done so, please return it to Newegg for an exchange or contact our US office at:
