Corsair VX 550W Is it enough?

[Jesus_Panella]

Hello.

I recently built my new computer, a Core i5 2500, with 8 GB DDR3 1600, along with an ASUS GTX 460 DirectCU 1 GB DDR5. I decided to use the Corsair VX550 as the power supply for my Core 2 Duo, since I bought this power supply a little over a year ago (I put a Thermaltake Litepower 600 W in the Core 2 Duo).

This computer only has a 1 TB hard drive and a DVD burner, and for now I don't plan to add any more drives, although I might add an SSD in the future.

I wonder if this power supply, the Corsair VX550, which has 41 amps on the +12V line, is more than enough to handle that configuration without any problems, or if it would be better to change it for a Corsair TX 650

I've seen that power supply pulling higher-end graphics cards, I think it can pull you. The Corsair Tx-650 V2 is a very good power supply anyway if you decide to change; but I would try to use the VX550.

in theory it should work with yours without any problems

Man, if you say you already have it set up... nothing better than you try it yourself... Open several programs, start playing at full... and see what happens :D.

I think you won't have any problems.

Yesterday I tried playing intensely and everything at full for an hour. But there was no problem with the power supply, as it remained cool. Very soon I found out that the consumption of the entire equipment (what I used at the power supply) fluctuated between 260 W and 280 W. That is, when playing intensely, having other programs running, the consumption of the entire equipment reached between 45% and 55% of the maximum capacity of the power supply (which is precisely when this power supply reaches its maximum efficiency).

I then understood why even at full load, the power supply remained cool. At the maximum load point it did not even reach 55% of its maximum capacity.

I finally opted for the power supply change, since the VX 550, although it was working well enough, might not be enough for me in the near future, possible SLI or a more power-hungry graphics card, or also the fact that it is actually an i5 2500K and not that I would overclock it to 4.5 GHz later. I changed it for the Corsair TX 650. I was hesitating to choose between the Corsair GS 600, the Corsair TX 650 and the Corsair GS 700 (I was already seeing the Corsair TX 750 as excessive for my PC). But seeing the few reviews of the Corsair GS series, I finally chose the Corsair TX 650 W (it has 52 Amps on the +12 V line).

Very good power supply, good choice, although I think the Corsair 550 is still a very good power supply and you didn't need to change.

Yes. I know that the Corsair VX550 is more than enough for a Core i5 2500K + GTX460, but the reason for the change is not due to that computer, but to the Core 2 Duo E8200 which has a GTX550 and has an additional hard drive. Previously this power supply was placed in the Core 2 Duo E8200 and previously I had put an 8800 GT in said Core 2 Duo. But the change of graphics card to the GTX550 and having changed that power supply to the Thermaltake Litepower 600 (which is actually a 500 W power supply), much inferior and much less efficient than the Corsair VX550, led to the change. Moreover, I have the Thermaltake Litepower 600 as a power supply to get by, since despite that power supply having active PFC, its efficiency is only 70% (it is not 80% plus, like the TX650 and the VX550). Now, after having bought the Corsair TX650 for the main computer, my Core 2 Duo E8200 has the Corsair VX550 again, since it is a computer that I am also giving a lot of strain.
