Is my PSU unit poweful enough?

[runzwithsizorz]

I have Seasonic x650 Gold 😕

Gaming at 1080p (Skyrim, Witcher 3 when it arrives)

Currently have MSI hawk 7870

Considering buying either : GTX 970 or R9 290

Will not be buying until I see "real" tech specs for Witcher 3 (after it's released)

Just worried about the PSU power. I only use one vid card.

Thanks,
The Wife

You'll be fine. I used to run 2x 770 with a 525W PSU, a single 290 or 970 is no problem.

A good quality 650W unit is perfect for that setup. You'll be just fine.

Thanks for the replies. I thought so. but then some vid card manufacturers recommended min 750w for 970 or 290.

You'll be fine. Seasonic is a very reputable PSU manufacturer; you can trust their units to consistently output the specified amount. I looked up the maximum power usage for a third-party, factory-overclocked R9 290X (which is about the most power-hungry single GPU card on the market today). TechPowerUp measured it at 316W. This is with Furmark; a normal game would use far less power (they found a peak of 253W and an average of 221W on Crysis 2). So, even if we go with the worst-case scenario to be on the safe side, that gives a power budget of 330W left over for the rest of the system. That's more than enough.

Your PSU unit is powerful enough to power a small ATM machine! 😛

But seriously, it's good.
