i7 6700K OC @ 4500Mhz 1.28v

A-DATA 16 GB DDR4 2OZ 2800MHz 1.24v

Reference Nvidia GTX 980 Ti @ 1250 MHz GPU clock, 2000MHz mem clock

I'm also connected to about 8 USB 3.0 devices via one hub and running dual monitors @ 1440p. I have a Corsair CX600M CX Series Modular 80 PLUS BRONZE as the PSU.

I also get like 90C+ on my 980 Ti in Furmark. I'm wondering if that's GPU issue or insufficient PSU..

Question: Is that 600W PSU enough? I've been reading around and even the calculator here (http://outervision.com/power-supply-calculator) tells me that I need at LEAST 650W. What do you guys think?

Question: Is that 600W PSU enough?

If you were using a good PSU, 600 watts would be fine.... but with the CX series which is not a good PSU you shouldn't be overclocking, I would stop overclocking and put everything back to stock until you get a good one.

That's what I was thinking.. ugh. Thanks

that is a small case so check if there would be a problem with a bigger PSU. If so get the cooler master VSM which is the shortest of them all. All the others psu are a little larger but you can check each one individually.

Thanks! Last question: I'm thinking of some hefty OCs. Would 650W hold? Or should I get 750W?

600 is fine, so the 650 will be more than fine!! The best 650 of all the options is the EVGA G2 650 (length =165mm), if you can afford it and it fits then go with that one. If size is a problem use the cooler master VSM (length = 140mm) or better the EVGA GS 650 (length =150mm).

the 650 G2 should fit as they offer the RMi650 and Thermaltake Toughpower as options. also, VSM 650 > 650 GS. ;)

max temp for the 980ti is 92C, so temps are really high (you need to be careful, as that is an expensive card). You are stressing to the max an overclock reference card that doesn't have the best optimal cooler. Reference card are great for water-cooling, but if you want to overclock on air, the ones with custom coolers are better.

Under normal loads (real world scenario), the card will never reach the stresses it receives from furmark, so i would just check temps while you are gaming. If you want to stress the card, i would do it at stock speeds.

what case do you have?

I forgot to mention that I ran furmark with stock clocks.

Case is a custom one made by CyberpowerPC, called Zeus Mini Evo. It's a pretty small form case so I didn't think GPUs that push air into the case would help.

Its true that in confine spaces the reference cooler may have an advantage. But this case is very similar to the silverstone RVZ02 which uses a riser and has the GPU in another compartment next to a side panel. I may be wrong but i think with a custom cooler it would run at lower temps and you don't have the problem of the card dumping hot air to the other components as the GPU is on top and the motherboard on bottom.

Anyways i would just do whatever has the more stress on your GPU and check temps. I don't think you should be stressing to the max your components in such a confine case with so many limitations regarding ventilation.

600 watts is enough but you should not use a budget psu for non budget hardware and overclocking, I would highly suggest replacing it with something like a Evga G2 or a Corsair RMi. Leave it to Cypberpower to put in a not so good psu so most likely when it goes out you will be too lazy to fix it yourself which is most likely what they are assuming and you will just buy another one from them which equals more money in their pockets.

I chose the CX600 myself haha. I didn't realize it would be bad since it was under Corsair's name. I should have researched. CyberpowerPC is not in the blame for this. :P

You can't chose psu by brand, you could have done worst, you could have just switched it out with a Diablotek psu.
