Do I need moar watts?

[TheDigitalRealm]

So, I'll be upgrading my GPU this year to two R9 290X Lightnings and will be water cooling my system. I plan on Overclocking these cards as high as possible without entering into unsafe voltages. Also, my 24/7 CPU (3770K) Overclock is 4.8 GHz @ 1.225V.

 

My power supply is an old 850W Corsair AX850 (the original AX series - 80+ Gold) and only has four 6/8 pin PCI-e connectors, so I won't be able to plug in the additional 6 pin connector on the 290X lightnings. (Which really bugs me, as I wanted to really push these cards)

 

Would you recommend a larger power supply for me considering I'll be running 1.3-1.35V through both the cards.

 

I was considering something like an RM1000 instead, but the low quality components puts me off.

The RM power supplies are a lot better now. I would get one of the 1,000 watt ones and roll with it.

no. you will be fine, unless you want the RM series stuff (no fan)

[jaffacakes]

You will use ~800w, if you want more headroom get a new one, or else just keep it.

I think I'll roll with my 850 for a while then, at least until the unused 6 pin PCI-e connectors start really bugging me (OCD).

hahaha well yeah, direct the money you would use for a PSU towards somehting else in your system, like a sexy PSU cover or something

I've got that covered - My new case is a White Enthoo Primo, and my recently dyed White Sabertooth motherboard . It's going to be a black and white theme, but when I saw the styling of the White Enthoo Primo in person, I knew I had to do an Aegis Dynamics theme. No spoilers, but White Vinyl wrap may be used on the two 480mm radiators...

well if you do decide to in the future get a more powerful PSU, i may be interested in yours, mine will soon not be adequate anymore (dat 140W 5820k)

I can pretty much say for certain that by the end of summer I'll probably have found an excuse to get a larger PSU.

 

I'd definitely be interested in selling to you, at a discounted "LTT forum member" price

Welcome I'm skint anyway since I've just brought the two 290X lightning cards, I figure this is just the life of a PC enthusiast and I should get used to having an empty bank account.
