650watt or 750watt for this build I have.

arronleeds

Hi guys I currently have that build but with just one 970 and I'm planning on getting another, I already have a 750 watt psu but it's not modular and im planning on getting a modular one and was wondering would I get away with a 650watt modular as with 2 970s as it only uses 487 watts ( thats on idle I'm guessing), I'd rather save some money.

If you don't go crazy on overclocks 650Watt are sufficient.

 

 

edit: and spend the extra £25 on the 4790K instead of the 4790

edit2: also I would get a single 980 Ti instead of 970 in SLI ;)

If you dont think youll be changing too much later on and not OC'ing too much, 650 should be fine

Get a 4790k you selected the non k also get z97 board or make very sure that the board has the latest BIOS or your cpu won't work.

You can get away with 650w but it will be close I would say get a 750w

Cheers guys il probs leave my 970s at stock if I get another, and as I said, I already have that build and have for months. I won't be getting another 970 for around 2 months as I currently don't work.

Edit- I'd rather have 2 970s as I'm not selling my 970 to lose money just to have to spend more on a 980ti, I could pick anither 970 up for £260.

I should have read your opening post ... :P

 

at stock 970 SLI and a non oced CPU is easly manageable by a 650W PSU ;)

Gooood :P, I might just get the 750watt anyway, I'm looking at the evga supernova NEX and the 750 is only £12 more than the 650.

well such a system (non-oced) should pretty much never draw more than 450 Watt.

A higher-rated PSU might be more quiet under similar loads.

Hey arronleeds,
 
You should be fine with a 650W even if you OC the CPU.
I'd either get the K-version of that CPU or get rid of the custom CPU cooler. Your current CPU cannot be OCed and the CPU cooler is not needed. Also you might want to swap the motherboard with a Z97 one as the Z87 would most probably need a BIOS update in order to run that CPU. 
 
I'd also throw in a SSD in that build as it would make the whole system much more responsive. :) WD Green is a great drive for storage and backups but might not be fast enough for more demanding and intensive applications.

The GS 650 is enough for 2 970s even when OC'd.  The NEX is a lower quality PSU than the GS.  In the long run, the 650W is a better deal.

I don't have that kind of money to be selling CPUs and cpu coolers to get a k model, I also already have an ssd but forgot to put it in th build. I bought that cooler so I could keep it for future purposes like getting a new cpu, maybe a 5820k in the future. The z87 works fine and has done since I've used it.

Please don't tell me to sell things I've already purchased, I wouldn't buy them if I didn't know what I was doing, I'm a gamer not an editor or renderer, I bought the 4790 as I got it for a good deal.

For two 970s at stock, heck a good quality 550W is enough.

jesus thats good, think il go for the 650watt to be on the safe side and for some minor ocing.

Get 750W. 650W is fine, yes, but in the long run taking into account cap degradation, overclocking and such, and the small price it costs to go from 650->750W, get the 750W.

i5 4670k - Z87X-UD3H - EVGA GTX 670 Sig 2 - Samsung 840 Evo 250GB - 8GB Avexir Core White 1600Mhz - Corsair 750D w/ RGB LED Mod & Remote Control - 2x SP120 - 3x Enermax Cluster - 2TB Seagate SSHD - Arctic Freezer 7 Pro Rev.2 - SuperFlower Leadex Gold 750W
