EfficientAffordableQuiet Cables could be longer I bought this power supply for a incredibly low energy server develop, but one particular in an Antec 300 case, which has the power provide at the bottom. I picked this PSU because it was the least costly, decently rated, decent efficiency provide I could discover in the size I necessary. I was a small dismayed when I went to assemble my server and found that the ATX იV cable was about an inch too short to attain the four-pin connector on my motherboard. I was able to snip a wiretie on the PSU and managed to make it attain, but there's a tiny bit of tension on the cable, and I'd like to replace it sooner or later. If it weren't for this small detail, I'd almost certainly have provided it a complete five eggs. It's not a poor energy supply otherwise, just watch your cable lengths before you acquire it.

It's SeaSonic, almost silent, energy effective. Has 24 pin + 4 pin motherboard power connectors, four sata and I think four molex connectors. Not modular, a mess of wires to harness up and out of the way Have had a 380 watt SeaSonic operating nearly 24ǝ for about six years and it's still going....blow the dust out of it each and every now and then....nonetheless silent and nonetheless steady...has survived quite a few energy outages without a surge protector. Hoping for the identical with this slightly less high priced one particular.

As constantly, happy with Seasonic items. PSU runs quietly (I can't hear it at all if I'm standing a couple feet away), and power on the rails is consistent (when not below load - haven't tested that yet). Could've wished for far more SATA energy adapters rather of the older 4-pin molex. Seems that given that IDE hasn't been accessible on the industry for a number of years now, new PSUs wouldn't have them any longer... I should've noticed the connector count in the pictures, but it didn't cross my mind.

Surely seems to be effective. I have an I5-750 with G210 passively-cooled video card idling at about 39 watts. The 120mm fan moves a decent amount of air but stays really quiet. None so far. It ought to be noted that I haven't installed a tough drive but (using an Intel X25-M SSD as the boot drive.) Nevertheless, my WD 1TB Green really should only bring idle power up to about 43W. And most of the time it'll be ramped down, maintaining my idle at about 40W.

Considerable power savings over common/older energy supplies. Utilizing a Kill A Watt device, I measured my system at 𞳃W. I was using a Sparkle PSU that's about two years old. Following switching to the SS-300ET, the power dropped to 𞲞W. My technique is on 24ǝ, so I figure the 37W savings will net about ำ-ุ a year in energy expense reduction. That'll just about pay back the price (ROI) in 1 year. Very recommended. Caps are "Su'scon" brand. Internet sites and discussions of the dreaded "Capacitor Plague" (early capacitor failures widespread in motherboards and power supplies) indicate this brand has had issues in the previous. Only time will inform if the SS-300ET will endure from capacitor failures also. I would have preferred to come across prime-quality capacitors inside. Higher high quality ADDA 120mm ball-bearing fan (AD1212MB-A71GL) is whisper quiet and I'd expect it to have a extremely long and dependable lifespan. This PSU is only 300W, but this is sufficient for numerous systems, and energy efficiency is generally greater employing a adequately sized PSU. If you wonder how considerably power your program in fact makes use of, get a "Kill A Watt" device (available on NewEgg and surprisingly affordable, in my opinion) and uncover out.

I bought 20 of these units over the final handful of months. Every single single one particular powered appropriate up and worked flawlessly. None have had any troubles at all. They're whisper quiet and save power. Even if a power supply is nonetheless operating, I believe it's worth upgrading to 1 of these for the power savings and quiet operation. None. Energy consumption is significantly reduced on every single technique when these power supplies are utilized to replace the normal one. For me, replacing a common 300W power provide nets a 20-30W reduction. When replacing an oversize energy provide 鸂W릾W), I've noticed 35-40W reduction, and these power supplies have no issue running the method.

I replaced an OEM Dell unit in an Optiplex 760. This PSU match just fine. It is rated at the exact same as the OEM version but draws five watts significantly less from the wall frequently according to my Kill-A-Watt! The SATA cables for the really hard drives have been virtually a stretch but perform ok. This PSU also seems much quieter that the OEM one. Perhaps the OEM was going bad for a while. OEM didn't come with energy cord so I utilized the old one. 80+ Bronze certified so it's fairly efficient! I can't wait 'till most PSU's are all Platinum certified, that'll save me far more dollars!

- Supplies the needed/expected power.- Has a lot of connectors Ɣ SATA on two leads, at least as several legacy).- Quiet fan.- Low energy draw.- Reasonably priced. None I am pleased so far with this PS. I'm running an ITX/ATOM CPU setup (low energy) and was seeking for a reasonably priced low wattage power supply. This fits perfectly. Operating the ASUS AT3IONT-I Intel Atom 330 MB wǚ WD 1 TB drives, max energy at boot is 53 watts. Common computing (as I type this) 45 watt. If I spin down the three drives in a RAID, 26-28 watts. Seems like I'm receiving lots of efficiency from the PS.

12cm fan, performs quiet. "OEM" product, comes in without a package, no energy cord included. this is very inconvenient. Following assembling all the component, you have to find a energy cord all over the world. If a energy cord is included, this would be a very good product to acquire.

Really quiet. Saves cash. None so far. I'm not one hundred% certain if the fan runs more quickly below greater case temperature. It probably does, since sometimes I notice the fan noise. Nonetheless, the noise is nowhere close to the common, standard PSU; Incredibly QUIET.

It's seriously quiet and the effectiveness really makes a distinction. None This PSU replaced the one particular that came free of charge with a ็ case. This Computer runs my safety method so it's on 24ǝ. On the old PSU it drew 122 watts. With this one, 91 watts. It will actually spend for itself in a small much less than a year.

Exceptionally quiet! At initially I couldn't think how quiet this unit is. My desktop computer sits in my basement 'office' region exactly where the only sound till now was constant humming of my old PSU.My setup: Athlon IIx4 45W with stock cooler, SSD, and now Seasonic PSU = I don't hear my desktop anymore. Let's see if it lasts. For SS-350 model folks reported bulging capacitors problem.

I've purchased about 30 of these over the final year. Most run 24ǝ in desktops and servers. I haven't had a single failure or dilemma of any kind. I've utilized quite a few brands and models of energy supplies over the years, and these are by far the best. They run whisper quiet, 300W is far more than enough for any system or server I have, and the power cost savings are substantial. Ideal of all is the reliability. It's a thing you can only know soon after running a handful of dozen units for a year or so and not obtaining any troubles. Thank you, SeaSonic, for creating such a good product! None.

This was the least expensive 1 with great critiques.The fans it has are superior than I expected, runs cooler than expected... incredibly fantastic PSU..

Low energy draw, silent, has steady voltages. has a lot of cables and connectors. Could power my method 10 instances more than. Not modular, but no tiny psu's are. Not gold certified, but no modest psus are. I didn't study the OEM and did not comprehend it comes with no energy cable. That's not a large deal, but it also didn't come with a Situation badge ;(. All in all a very good psu.Seasonic, Please make modular psu that is gold certified and only 200 or 300 watts. I would like the very same as my x750 but in a low wattage. Low energy was my biggest concern in this build so i would spend double or triple for a 80+ gold certified.

- Quiet- Efficient : The consumption of my tiny server drop from 64W to 42W when idling. Previous PSU was a extremely old Antec 430W - Cables are brief : In my case, the PSU is located at the bottom, so I had to use extensions for motherboard energy cables

Began up appropriate away (which is additional than a lot of elements do LOL) As someone else mentioned the 12volt 4 pin energy wire is way to brief. I have it stretched to the limit and I will have to get an extender to lessen the tension.Is it just me or is the On/Off switch upside down? I replaced a power supply from CoolerMaster which came with the situation but went poor when I was undertaking some electrical operate on property and was switching the breakers on and off.(I bought a fantastic surge protector now)I don't care about power cords as other people talked about as I have them coming out of my ears.

Efficient, Quiet, Reliable, Stable Voltage Out, Pays for itself None The best is acquiring much better. Since about two years ago, I started purchasing SeaSonic PSUs for all my builds. They might be a bit a lot more pricey up front, you recover the costs in a year or two. This most recent incarnation is quieter than my Seagate 7200.12 1 Tera drive. Employing it to power my NAS server with 3 hdds, and 65W Athlon 64 X2 cpu with Nvidia GF8200 Board. Killawatt shows peak 145 W at start up, memtest of 4 gigs at 95 W, and idles at 30-50 W depends on how a lot of drives are sleeping. So my guess it will most likely help a typical gaming system just fine.Cable length is very sufficient for the full tower case (CM Centurion 5)Just wish SeaSonic would make 100, 150 and 200 W units and NewEgg would sell them.

Silent running: On my HTPC, this replacement power provide took the sound level from "irritating white noise" to "completely inaudible". I don't think the fan is running at all at my power levels, so the PSU is totally silent.Power Saver: 1 goal of my new HTPC was to lower the power consumption over the system it was replacing. The HTPC is my residence server, and is on 24ǝ. The old technique was 118w or so at idle. The new construct was about 68w on the old power provide. Basically substituting the Seasonic SS-300ET dropped that to 53-55w on otherwise identical hardware. This savings of 14w represents about ภ a year in power savings, and roughly 20% of my overall power for the technique. It's achievable that greater-power systems may save a lot more.Nice assortment of power connectors. None. Slightly longer than the came-with-the-case PSU I was replacing, but I knew that going in. Make positive it fits! The 120V AC plug on the back was in a slightly different location, requiring me to snip off a little bit of aluminum from the case. No genuine problem there.Change-out took about five minutes.For the mobo power, there's a 12x2 and an auxiliary 2x2 12V. Check if your mobo calls for a 2x4 ƒ 2x2s) -- far more frequent with the additional recent mobos.I believe most individuals more than-PSU their systems. My power peaks (at boot) at 112w. The 420w power provide that came with my case was definitely overkill for me.

Speak about quiet. Given that it regulates the fan on a desires base this factor has yet to kick into high gear. Mainly because its powering a Intel Atom based method. Seriously it fit the bill, I see why SeaSonic is extremely rated by those who desire silent computers. None at all.
