Seasonic S12II 620 SS-620GB 620W 80+ Bronze ATX12V & EPS12V Direct Cable Wire 105 °C Japanese Capacitor Power Supply

Installed this power supply today and I need to say I am impressed. The cables are sufficient both in length and quantity of power connectors. The supplied tie wraps come in handy. But what is most impressive is the lack of noise both to the ear and electrically. I am ham radio operator who uses SDR equipment. My computer was generating horrendous EMI/RFI. Disconnecting everything from the computer (even pulled the graphics card), I found either the power supply or the mother board itself was generating the interference. Since the fan in the old power supply was making quite a bit of noise, I opted to replace the power supply with this unit. After replacing the power supply and booting up with everything plugged into the computer, the EMI/RFI is completely gone! Also the audible noise from this power supply is non existent. The only noise my computer now generates is a bit of noise from two large cooling fans running at half speed.Bottom line: This is a very good power supply.

This thing is great. I purchased an IBuyPower entry level setup and have started to make improvements here and there. I previously had a cheap Allied 500w psu and I did not need the 620w by any means but for the price I figured down the road I might need it eventually and it doesn't hurt.But compared to my previous psu this thing is so much nicer. (quiter, better built, certified) I was tempted to go with a Corsair or EVGA etc. since those are the common names on psu's but it seemed like every where i looked these Seasonic units seemed to get great feedback. Really happy with my purchase. Wires are a little stiff that's for sure but my case has a smaller window and I was able to hide them nicely. (Love the Velcro straps.)

I have been using this for around 3 months with: R5 2400G, ASRock AB350M Pro4, a 1060 6GB, an SSD, a hard drive, 16GB 3200 MHz memory and 3 case fans. It is probably still overkill in terms of wattage. I have had freezing problems with the motherboard which I don't think is fault of the power supply. Plus the problems have subsided for now with a few BIOS changes so it seems no permanent damage has been done.Though this power supply has outdated design according to power supply review sites, I hope it will last a while. It has been through a couple of power outages with no UPS with no problems afterwards.Overall it has been a steady, unremarkable unit, which is good.

Product is ok. It's a power supply, and it does just that. But, all the cables are short; meaning cable management is a pain. I'm using the power supply in an NZXT H440 case, and the CPU 12v 4+4 connector required I run the cable in front of the motherboard to reach the header on the top of the motherboard.Not bad for the price, but I would likely buy a different power supply in the future.

I bought it recently. no problem whatsoever. neat finish, did fit my box perfect, it has all connections you might desire, and the power is truly consistent.. I thought it may be little an underpowered product for my setting, but I have had no problem at all: silent and complete. If you need reliability this product has, in well over three months, proven its quality, even on heavy loads. congratulations to the brand.There is not much else to say. If you need power on a budget, this product is well built, and has only given me pleasant surprises. (like for instance more than enough connections to power my game computer, in a not to expensive but aggressive double video card setting)Instruction manual can be improved a bit, but if you take your time to read it it has all info you need.

New review:I have irrefutable proof that AT LEAST THREE major PSU brands on Amazon, Seasonic, Corsair and EVGA are selling cheaply made power supplies for higher prices than ever and none of which are robust enough to power a socket 478 motherboard.#1 None come with 20 pin and 4 pin socket 478 MB cables anymore.#2 when I get the 20 and 24 pin connectorsx and connect any of my socket 478 mbs to them, theyexperience sudden PSU death without ever even coming on.#3 a Corsair Customer service person claimed that Corsairs work with all PCs, but a Corsair technician saidthat none of the current models work with socket 478 MBs and that PSU sudden death is a possibility.#4 I just got a used older PSU for my socket 478 MB and its much heavier than the lightweight, moreexpensive 24=8 pin-only new ones.#5 Previous PSU's from a few years ago had both 20 +4 pin configs and 24+8, unlike today's lightweights#6 Pentium 4 CPUs were notorious power consumers of something like 90 watts by themselves.#7 if the previous points didn't clue the reader of this fact, here it is again condensed: All of the PSUbrands are hiding the fact that they've been selling ONLY cheap, lightweight PSUs that won't powerolder PCs & charging about 30% more for today's cheap junk PSUsSeasonic missed it by THIS MUCH (The 5 year warranty BY 3 YEARS)! This Turkey PSU from this fly-by-night outfit came DOA out of the box and therefore is the first and last PSU of this brand I will ever buy.5 year warranty on product page IS FAKE ADVERTISING. 2 yrs later its dead as doornail, won't even fire up any fans & when I went to Seasonic and filed out all the required information to return it under the warranty and clicked "send", the Seasonic website returned the message "your product is out of warranty!"

My new Seasonic 620 Watt PSU arrived at the door earlier than expected which was a nice surprise.The unit smelled new coming out of the box (freshly extruded polymeric cable insulation) and the condition of the unit was as promised by Seasonic.Higher quality switch,fan, and case over my older unit.Zero issues hooking it up,the flat cables offer improved air flow over the 8 year old PSU I had to discard. Plus, I have all the attachments (GPU) I need if I want to follow my son into gaming.There has been absolutely no sound coming from the Seasonic , it simply provides a steady current.
