Antec Signature Series SP1300, 80 PLUS Platinum Certified, 1300W Full Modular with OC Link Feature, PhaseWave Design, Full Top-Grade Japanese Caps, Zero RPM Mode, 135 mm FDB Silence & 10-Year Warranty

Doesn't have enough pcie cables to handle multiple GPUsyup... avoid this oneUpdate : sent back the unit yang amazon's print label system and NEVER got the refund, it was an eternal back and fourth between Amazon and the third party seller and I have NOT had any refund after 7 months...By far my worst experience with Amazon!

The title says it all. 1300w of raw power. Its literally a Seasonic clone, aka "rebrand" which means you are getting amazing quality for the price. 80plus platinum means you can expect quality power conversion from AC to DC. And with 1300w, you got more than enough to spare. Some might claim "you don't need that much" however I can prove you wrong.3950x, overclocked to hell and back. Radeon VII overclocked to hell and back (getting big navi soon), 32gb 3600cl16 ram (4x8GB), Sound Blaster AE-9 sound card (has its own 6 pin pci-e power), enterprise grade networking 10G card, three 7200rpm storage drives, one 500gb ssd, one 512gb nvme (soon to be 2tb pci-e 4.0 when samsung gets off their booty), six 120mm fans, two 140mm fans, one 80mm fan. All together, doing productivity, I can eat 1000w with this setup.I want to point out, a lot of people complaining their brand new shiny 3080 is crashing. They start blaming caps and all this other b/s that isn't founded on anything but one company claiming "this is why we designed our cards the way we did". When you look at the power delivery, why do you think Nvidia even decided to go with a new 12pin power connector? Because people were messing up even back with the 2080ti and blaming THEM for their own mistakes. I had a buddy with an 8700k and titan, on a 450w because "that is what pc part picker suggested".... shake my head. His pc didn't crash, he just got insanely low fps. GPU have different power states, and his titan got stuck in the lower power states. Well he took my advice, bought an 850w psu, and magically he went from significantly less fps than others with cheaper weaker gpu's to absolutely out performing everyone he knew. You need power. There is a reason why they will claim "TDP" and then "recommended system power". If you want to find out what your system will use, I recommended the Seasonic power calculator on their website. For gaming, set the "TDP/LOAD" to 50% and see what your power usage ends up at.... most likely your system doesn't have enough.For my story, I had an 850w already. But that was for my 1800x system. When I upgraded, I didn't upgrade power thinking "its enough" like everyone else. I was crashing constantly, especially in certain heavy workloads. The solution at that time was to lower my overclocks. Now some might argue "well that means your overclocks were not stable". NOT SO. After buying this 1300w psu, I put all the clocks back up to the insane levels I was at, and now everything is running no crashing ever. Now some might argue "well that means your old psu was bad" incorrect again. If it was bad, it wouldn't have ran my 1800x system prior. And I ended up testing it in another rig and it runs fine. The issue was power amounts. These newer Nvidia gpu's suck power like a vampire, and people seriously think they can run 550w psu's and think it will work because some youtuber told them so.Those "kill-a-watt" wall worts these reviewers use to read power, don't read peak, they read RMS aka the average. Which means when a particular youtuber claims "523w total system power" that was the AVERAGE wall power pull. If you want to know what you are ACTUALLY using, multiply that number by 1.41.... 523*1.41=737.43 watts of ACTUAL used power. No wonder people are crashing when the gpu tries to hit 2ghz. They simply aren't feeding it enough power. nvidia assumed going with a 12pin power connector would solve this issue. But there is no limit to human stupidity. And what did nvidia do? they updated their driver to reduce the clock speed, since people are too lazy to buy proper wattage powersupplies for their rig.Long story short, always get more power than you think you need, because most likely, you actually need it. I can't count how many reddit posts I see where someone complains of crashing or black screen, and its all from not having enough power to do it. It would be like trying to drive a car without gas.... you aint going anywhere fast!

The Antec Signature SP1300 is a great PSU that is based on their OEM Seasonsic's SSR-1300PD. If you compare the modular layout it's exactly the same, except the Antec Signature has OC Link to link more then one Antec Signature PSU. The PSU powers on with the fan at full speed for a split second and then quickly settles down. During operation the fan is relatively quiet. The cables are wrapped in wire loom tubing sleeves which makes for a cleaner appearing build. Overall I'm please with the PSU.

Antec used the be a high quality American based company with stellar products and service. They were sold to a company in Asia and now mostly sell rebranded junk that comes with long warranties that they then don't honor. The contact information on their website is all inaccurate/obsolete and they have one sole method to reach them. If they respond they are rude and don't care that you bought a new item with a 10yr warranty, they just tell you to send it back to vendor then ignore you. This high end PSU blew up in one week..they did not want to help me. Garbage. If you look online you will see similar complaints about this now crap brand.

This is a well made modular PSU with a single 1300w 12v rail for todays power hungry gaming PC’s. You can also get a second 1300w unit and connect the PSU’s via the OC link cable to effectively create a single 2600w PSU - something you can only find in server power supplies. Just make sure you have two separate 15-20 amp outlets to power them, as a standard 15 amp household outlet max’s out at 1800 watts (and best to not load it over 90%, or 1620w).Antecs support is horrible though so far. I’ve dealt with them once, but its been frustrating. These PSU’s come with 10 - 8 pin outputs, yet they only provide you with 6 - 8 pin cables. I asked about getting more, and they said I will overload the PSU, throwing out numbers they pulled out of their a**. They dont even know my setup! Anyways, very frustrating. Ill just make my own cables.
