SilverStone Technology 450W SFX Form Factor 80 Plus Bronze Power Supply with +12V Single Rail, Active PFC (ST45SF)

I had this in my FT03 MINI ITX build until switching cases and upgrading from a GTX 660 ti to a GTX 770 ACX. To this day, I'm sure that the power supply could handle a GTX 770, as I've seen this power supply been used to power a Titan. Build quality of the PSU is great, however be careful not to scratch it, the paint does come off very easily. I had this powering an i5-3450 and a 660 ti which I would let run Folding@Home every day which uses a lot of your systems resources and the PSU never skipped a beat. The fan also is not very loud, I could never hear it, but that was over the CPU and GPU fans. I believe this is one of the very few solid SFX PSU's but if you're okay with it not being modular, it is very solid. I would buy another!

Using this in my HTPC and it works brilliantly. Very quite and super efficient. I have it powering: A10-6800K ASRock FM2A88X-ITX+ 2 WD 2TB Red Drives Some BluRay Drive 1 TB 2.5 inch drive 128 GB SSD GTX 650 Ti 200mm Fan 120mm Fan H80i water pump The CPU is OC'ed to 4.2GHz, everything else is stock This PSU has no problem whatsoever and powers all of the above and is super quiet in the process. Only complaint: I wish the metal bracket that converts the SFX to regular PSU size was black like this PSU and not silver/grey (looks like an old PC case)

1. PSU is heavy in hand. It means Silverstone has used good materials on this product. 2. Black finish looks and feels excellent. 3. VERY quiet in the case. Fan noise is barely noticeable. 4. Enough power for an AMD A8 CPU, 8GB RAM, 128GB SSD, 2TB HDD, Blu-ray drive, and Radeon 5870. 5. I paid for FULL price (now it's $10 cheaper on Amazon) for this PSU and expected to receive a PSU with ALL cables sleeved. This is nearly a standard practice for today's high-end PSU manufacturers. But Silverstone is SO STINGY on sleeving PSU cables. PSU has cables sleeves on 24 pin power wire and a few other wire, but leaves SATA cables, Molex Cables, and the Floppy cable all exposed. I have to pay extra $15 to buy cable sleeves. I should have deducted TWO stars for you, Silverstone. The cable sleeve is something should be done correctly the first time, not on Version 2.0 or 3.0!!

It works just fine so far. As others have stated, the cables are MUCH too short. If you are even considering this, you might as well get extenders when you buy it. If not, you will need to order them after you realize they are too short. It is nowhere near silent. I am using it in a HTPC. I can definitely hear it anytime the volume is low.

I got this PSU for my shoe-box sized Thermaltake Power Supply Mini Case Mini ITX 200 VL52021N2U to replace the included ThermalTake 220 watt power supply unit, and they both seem to be the exact same size. However, the SilverStone is much beefier and the build quality is very impressive. With a Core i5 2500K Sandy Bridge CPU and a Radeon HD 6850, the 450 watts should be more than enough. It was really nice of SilverStone to include four black case thumbscrews and four black mounting screws since the ThermalTake ones were pretty crummy. 6-pin AND an 8-pin PCIe power connectors really simplify things if you get a powerful video card. The 80 Plus Bronze rating shows you're getting a thoroughly modern and efficient PSU in a SFX form factor, although you do pay the price for it. I also considered a SeaSonic 350w (less power, too plain) and an Athena Apollo 470w (never heard of them, no 80 Plus). I did a quick check of the voltages and all three rails, 3.3v, 5v and 12v, were slightly over while idle, which I think is good. In practice, it has been absolutely rock stable and amazingly quiet even under load. If you are building a mini-ITX PC, you don't have many choices, so I would highly recommend spending a little extra and getting the SilverStone ST45SF. The power supply is the foundation for the stability of your entire system and this one makes very few compromises for its SFX form factor. Lastly, it's also very quiet, easily drowned out by my video card and CPU fan even at idle. UPDATE: So mine failed (Aug 7, 2011). When I turn on the PC, the fans would spin a few seconds, then turn off, and repeat this forever. I RMA'd it with SilverStone and they sent a new replacement unit within a few days! So even though America is crumbling around us, SilverStone came through with awesomeness and they deserve a beer. Fingers crossed this one lasts longer. UPDATE (Mar 29, 2012): It's still going strong, surviving many torturous 4+ hour gaming marathons and it has the brutal job of exhausting the heat from the CPU as well as its own heat (the GPU is off in its own thermal world). It's brutal because of how tiny the case is and how much power I tried to stuff in it, but my PC has been absolutely stable with not a single crash or unexpected shutdown. *No need to knock on wood*

arrived on time and it did fit in my atx case with the adapter plate that comes with the unit. I did have to mount it upside down so the power cord would reach all the spots on the mother board. This unit is extremely quiet and has been working on my htpc for about a month now with not problems. The smaller footprint is what I needed in my Silverstone case so that it didn't interfere with the optic drive. great little unit.

First one failed in 24 hours. The second one had capacitors making a constant chirping sound. Garbage.

I bought it for a replacement in a mini ATX build and it gets the job done but man is it loud even at idle it revs up and its the loudest part in my PC
