Another PSU rating question

post #1 of 6
Thread Starter 
Hi
I'm new to this forum and also to system building. I'm planning to build the system below and will look to over clock the CPU and video card. At some point i will add an SSD and maybe even a second video card.

From using an online calculator I thought a Corsair HX650 would do me fine but the computer store has told me it's not enough. Are they right or are they just trying to get me to spend more?

Thanks in advance
Chris

Any quality 550W would suffice for your needs.

By the way, SSD power draw is negligible, in the milliwatts.

Thanks but it seems like a good 550w PSU such as Seasonic x 560 will cost me a lot more? Will it save me over the long run?

well for 2 6850's a 550watts could do it but its usually recommended to go for 600watts so the hx650 would do fine but there are other options like the seasonic x650 which isn't much more then the hx650 but better then the hx

lol, the computer store kinda lied. The HX650 (or generally, anything within that range and above) will suit your needs perfectly. (Yes, including the crossfire)

Whether or not 650W is enough for Crossfire depends on the video card, but if it's the 6850 in your signature, 650W is definitely enough -- for that matter, 550W would still be enough. If your store has any of the following units, they would be my recommendation:
Antec Neo Eco 520C
Antec High Current Gamer 520
XFX 550W
SeaSonic S12II or M12II 520
They're all great, won't break the bank, and would easily power a system with an overclocked Core i5 2500K and a pair of 6850s.
