Hello Guys.

I saw a lot of things here that helped me, but this time I must ask.

I have a FX 6300 @ 3.5Ghz with 8gb ram 1600Mhz and a WD Blue 1tb. I want to replace my R7 250 (no X) with a R9 270x or maybe a GTX 970. Can I? What do you think?

The PSU has dual rail +12v with 18A, so I guess I have 32A there.

Right now I'm gaming at 768p but I want to jump to 1080p if it is possible.

Thanks and greetings from Argentina!

OK. Good. You are aware of what I meant then. If this is your PSU: http://www.taringa.net/comunidades/serviciotecnico/8508867/Consulta-Fuente-Vitsuba-550w-Reales.html
...I'm not familiar with that make. But it appears to be good quality and can meet its requirements for the 145W gfx card and the 95W CPU.

I saw that the real amperage with dual rail was 12v1 + 12v2 - 11%. That's why I said 32. The rails delivers 340w, so I'm getting 28A then :/

I'ts a Vitsuba san 55 s 550w 80 plus Bronze.

A maximum combined +12V rail rating of 28 Amps for a 550 Watt PSU is quite poor. A good 550W PSU would have a maximum combined +12V rail rating of 45 Amps.

If that PSU only comes with one PCI Express supplementary power connector then for sure it's not sufficient for a Radeon R9 270X since a Reference Design Radeon R9 270X requires two 75 Watt 6-pin PCI Express supplementary power connectors. It's also insufficient for a GeForce GTX 970 that also requires at least two 75 Watt 6-pin PCI Express supplementary power connectors

Vitsuba has used Andyson as the OEM in the past for a PSU with that exact same model number.

I don't see that PSU in the 80 PLUS certification database.

This seller says it only comes with one 6-pin PCI Express supplementary power connector:

But the box includes a 2 molex to 6 pin connector. There is a reason to include it.. I think

The dual 4-pin Molex peripheral to 6-pin PCIe adapter power cable should only be used if the PSU has sufficient combined +12V capacity and an insufficient number of PCIe power connectors.

The fact that your supposed "550" Watt PSU only came with one 6-pin PCIe power connector is enough to say that its combined +12V capacity is insufficient.
