    I think Corsair makes some of the best consumer power supplies, for the money. Better on sale! I have been using nothing else in my last 3 builds. 80 Plus Gold or better. Never had any issues. I do my research before I buy, so if these were not a good PS, I would not bother. You can do a lot worse. Do yourself a favor and avoid cheap power supplies. Buy 80 + Gold.

    I recently installed the CORSAIR RM750x Fully Modular ATX Power Supply in my gaming machine, and I have to say, I’m pretty impressed. First off, the fully modular design is a game-changer – no more cables cluttering up my case. I only used the cables I needed, making cable management a breeze.The 750W is more than enough to power my setup, and it runs super quietly – I barely hear a thing, even during intense gaming sessions. It’s also got plenty of headroom for future upgrades, which is great.Overall, the RM750x feels like a top-tier power supply – solid, reliable, and built to handle the demands of a high-performance gaming machine. If you're building a gaming rig and want something that won’t disappoint, this is the one to go for. Just plug it in, sit back, and let the power flow

    Excelente fonte, não apresenta defeitos e suporta o computador mesmo quando este consome seus 500W~ sob full load e com picos de tensão. 10 anos de garantia da fábrica, qualidade Corsair/Seasonic. Altamente recomendado, nunca economize na sua fonte.

    Used it to power my i9 9900 and 4080. No problems for the last few years. I only switched out to a RM1200 because I upgraded to a 5090 and 9950x3d. The 1000w is still in my old computer as backup and probably can be used as backup for my current computer for light work.

    So this is a great psu, excellent quality and provides all the power I could ever need for my AMD rig, which has an RTX 30 series card, AMD Ryzen 5 5600x, 3 SSDs, a wifi card and 16GB of 3200Mhz ram.The quality is excellent and this thing feels like a tank. It comes with all the cables you would generally need for a gaming PC and more (I ended up having a leftover CPU cable as well as some molex cables and a SATA cable.PLEASE NOTE: I read all the reviews and questions about this PSU before buying and a lot of reviews were saying it does not come with enough PCIe cables to power a 3 plug RTX 30 series card. So I went out and bought a pack of PCIe cables for this so i would have enough (as the RTX 30 series cards need 3 8-pin connectors). Only to find out THIS PSU COMES WITH 3 8-PIN CONNECTORS (well the connectors are actually 6+2-pin by the way) so I bought the extra cables for no reason, however I'm a PC enthusiast so the cables will not go to waste.However I think it's pretty foolish that people are saying it doesn't come with enough cables when it actually DOES.I would highly recommend this PSU and I see it lasting a very long time as I have only ever used Corsair PSUs and never had one die on me. It seems sturdy and well made.It's also crazy quiet with no coil whine, I can put my PC on full load, and I cannot even hear this PSU, it makes it seem like it's not even struggling to provide the power needed for my PC, and that's awesome.

    Quise cambiar de fuente de poder porque la que tenía (una básica genérica) empezó a hacer un ruido extraño e insoportablemente molesto.La mayoría de mis componentes han sido Corsair, es una marca por la que bien puedo meter las manos al fuego, todo ha sido de muy buena calidad. Y esta fuente no fue la excepción.Al encender mi PC con esta nueva fuente "rugió" por unos segundos y después trabajó en silencio, incluso mientras juego. Su nivel de ruido es apenas perceptible, nada que te afecte al micrófono o tu teléfono para llamadas.El diseño es muy simple, a diferencia de otras que son más vistosas, pero bueno, hay gabinetes que la cubren por completo y eso ya no es un inconveniente.
